Welcome to HDLink.

We hope you share our dream for the television industry to become a truly creative industry by allowing
everyone access to the highest quality video.

Previously SDI monitoring required small and very expensive CRT displays which were unable to show
the full detail of the video image. HDLink has changed all that and now full resolution SDI monitoring
with pixel-for-pixel accuracy is affordable for everyone using large flat screen displays. We hope you
get years of use from your new HDLink and have fun monitoring your video and film with full digital
accuracy on a large display with DVI, HDMI or DisplayPort connections.

This instruction manual should contain all the information you’ll need on installing your HDLink. We
think it should take you approximately 5 minutes to complete installation. Before you install HDLink,
please check our website at www.blackmagic-design.com and click the support page to download the
latest updates to this manual and HDLink driver software.

If you’ve previously purchased a HDLink Pro Displayport, you can update its features to that of HDLink Pro
3D by updating its firmware with the latest HDLink software. This is a free update and another good reason
to check the support page for the latest HDLink updates.

Lastly, please register your HDLink when downloading software updates. We would love to keep you
updated on new software updates and new features for your HDLink. Perhaps you can even send
us any suggestions for improvements to the software. We are constantly working on new features and
improvements, so we would love to hear from you!

After running the HDLink software installer, a USB driver will be installed on your system and the HDLink
Utility will be added to the Applications or Programs folder. To use the HDLink Utility, you will need to connect
HDLink as follows.

1. Connect the 12 volt power supply which was included with your HDLink. The white power lamp
will illuminate.

2. Connect a USB cable between HDLink and a USB 2.0 port on your computer.

3. Open the HDLink Utility and the settings should be adjustable. If they are disabled and unadjustable,
check the USB connection to the HDLink, try another USB cable or try another USB port on your
host computer.

4. If your version of the HDLink Utility contains newer firmware than is currently installed on the HDLink, you
will be prompted to update the firmware. You must allow the firmware to be updated before you can
use this version of HDLink Utility to configure the HDLink. Select ‘download firmware’ for the firmware
to be updated.

5. If the firmware has been updated, it is important you unplug the power cable from HDLink, wait
5 seconds, and then plug in the power cable again. This ensures the HDLink is reset correctly.

6. HDLink allows 3D lookup tables (LUTs) to be applied to the display output. You can make changes to
lift, gamma and gain settings for red, green and blue color, and import custom 3D lookup tables. These
HDLink models will also import 1D tables created for the original HDLink. Changes to settings can be
seen on the DVI-D, HDMI or DisplayPort output in real time allowing accurate setup.

7. 3D lookup tables can be applied to the loop-through SDI and optical fiber SDI outputs, so you can use
the outputs for inline video processing. Simply enable the Send to all video outputs checkbox in the
Settings of HDLink Utility to enable 3D lookup table processing on all video outputs.

8. Changes made in the Settings tab of the HDLink Utility are updated immediately and don’t need HDLink
to be restarted.

The HDLink Utility interface is the same for all current models of HDLink on both Mac OS X and Windows
platforms. Any features that are not applicable to your HDLink model will be grayed out and inactive.

Lookup Tables (LUTs)

8

HDLink supports the use of LUTs to adjust the appearance of video on your monitor and optionally on the loop­through SDI output. Lookup tables can be used for standard definition and high definition video as well as 2K film.

All current models of HDLink are capable of enabling LUTs on the monitor output when working with the
demanding 1080p50/60 video formats. HDLink Pro 3D is also capable of optionally applying 3D or 1D lookup tables
to 1080p50/60 video, on its loop-through SDI output, as it has a more powerful processor than previous models of
HDLink.

1D LUTs are useful for making quick adjustments to a video image but any adjustments to color will also affect
brightness. They are often used when working with log video so that the image can be displayed on screen as
normal linear video. Built-in 1D LUTs are provided for log to linear conversion when playing video captured from
Panasonic Cinegamma

™

and Viper Filmstream™ cameras. 1D LUTs are supported in all HDLink models.

3D LUTs provide the ability to increase and decrease the amount of color in each color channel independently
from brightness. This allows for precise color grading to ensure a video monitor matches the color printed to tape
or film. 3D LUTs are supported in current HDLink models.

How to use Lookup Tables in HDLink

Connect HDLink to your computer with a USB cable.

Launch the HDLink Utility from your Applications folder in Mac OS X or from Programs in Microsoft Windows.
The HDLink interface should immediately be visible and adjustable. If the interface does not appear to be “active”,
check the USB connection, try another USB cable or try another USB port and it should become active.

The lookup table interface in HDLink Utility can be adjusted using a method similar to that used for image
adjustment with the Curves feature in Adobe Photoshop

™

. The horizontal axis of each graph represents the
original color input values and the vertical axis represents the new color output values. When first opened, each
lookup table displays a straight diagonal line because the color values have not yet been changed.

Changes made to the lookup tables can immediately be seen on a monitor attached to the DVI/HDMI or
DisplayPort output of HDLink. Changes are saved to the HDLink hardware by clicking the Download button so
that you don’t need to leave HDLink connected to your computer via USB. Lookup tables can be reset to original
values by clicking the Reset Unity button and this effectively disables the lookup tables. Click the Download
button again if you wish to save the original values.

Importing and exporting 3D LUTs

Current HDLink models support the popular Autodesk .3dl, IRIDAS .itx and IRIDAS .cube lookup table formats
when importing 3D LUTs. Click the Load Table button to load lookup tables.

3D LUTs can also be exported from HDLink in the .cube format. HDLink uses the .cube format to store 3D LUTs
internally as this is a most memory efficient way to store complex lookup tables. Both 3D LUTs created with curves
in the lookup table interface, and 3D LUTs imported from .3dl, .itx and .cube files, are exported from HDLink in
the .cube format. Click the Save Table button to save lookup tables.

The .cube file format is fully compatible with current and previous Blackmagic Design products which share the
same LUT format: HDLink Pro 3D, HDLink Optical Fiber, HDLink Pro DVI Digital, Multibridge Eclipse, Multibridge
Pro (October 2007 model) and DeckLink HD Extreme 2.

Importing and exporting 1D LUTs

All HDLink models can import 1D LUTs. The 1D file format is any tab-delimited text file with red, green and blue
values for each record and the first line (title line) is skipped. Lookup tables need to be 1024 records long with
the first line reserved for the title line. Check out the sample 1D lookup table accompanying the HDLink software
installer. 1D lookup tables can be created in a spreadsheet program and then must be exported to a ‘tab separated’
text file prior to being imported in to HDLink Utility. Click the Load Table button to load lookup tables.

1D LUTs can also be exported from HDLink in the same text format mentioned above. Both 1D LUTs created with
the curves in the lookup table interface, and 1D LUTs imported from text files, are exported from HDLink in the
same text format. Click the Save Table button to save lookup tables.

The 1D LUT text file format is fully compatible with the following Blackmagic Design products which share the
same LUT format: HDLink Pro 3D, HDLink Optical Fiber, HDLink Pro DVI Digital, HDLink 2, HDLink, Multibridge
Eclipse, Multibridge Pro (October 2007 model), Multibridge Extreme (DVI output), DeckLink HD Extreme 2 and
DeckLink HD Pro 4:4:4 (PCI-X).

Settings

HDLink Utility provides several settings for current HDLink models.

Scale video to fill larger display.

Most HDMI displays automatically scale video to fill the screen so a PAL or NTSC image would automatically
scale to fill the high definition display. By contrast, DVI and DisplayPort displays rarely provide scaling. This
option enables current HDLink models to scale smaller video formats to fill larger DVI and DisplayPort displays
and avoid thick black borders around the video. When this feature is used with SD video, the aspect ratio
chosen below will also be applied.

Standard definition video scales as:

1:1 Direct pixel for pixel

This option allows for precise pixel-for-pixel viewing of standard definition video. However as HDLink uses
square pixels, and standard definition video uses rectangular pixels, your video may seem squashed and
circles may appear to be egg-shaped.

4:3 Aspect ratio

This option scales standard definition video in the traditional 4:3 aspect ratio so it will appear normally on
your computer display via HDLink. Circles will appear as circles as expected but the image will no longer
be presented pixel-for-pixel.

16:9 Anamorphic aspect ratio

This option scales widescreen standard definition video to appear in the expected 16:9 aspect ratio on the
computer monitor attached to HDLink. The image will appear correctly but will no longer be presented
pixel-for-pixel.

Display video using blue only

This option enables blue only mode which is helpful in detecting noise in video.

Simulate interlace on monitor

This option attempts to display interlaced video on progressive DVI and DisplayPort monitors, with a similar look
to traditional CRT monitors, and to avoid video tearing.

When a lookup table is used, Send to all video outputs.

This option sends the effect of any lookup tables to all HDLink outputs. It is useful for inline color correction of an
SDI signal as the effect of the LUTs will be seen on all SDI, optical fiber SDI, DVI/HDMI and DisplayPort outputs
of your HDLink model. If you want to leave the SDI output unchanged, and only apply the LUTs to the attached
display, leave this option unchecked.

3D settings

HDLink Pro 3D supports dual stream 3D HD-SDI input and output to compatible 3D displays with a HDMI, DVI or
DisplayPort connection. HDLink Utility provides several settings to control 3D behavior.

3D stereoscopic.

Enabling this option configures HDLink Pro 3D to receive dual stream HD-SDI input and mux the signals for
display on a 3D monitor. Disabling this option returns HDLink Pro 3D to traditional 2D operation.

3D stereoscopic output format.

There are a number of different standards for 3D stereoscopic video. Select a standard that is supported by your
3D display from the following list: Side by Side, Line by Line and Top and Bottom.

Apply video adjustment.

If you have used a beam splitter camera rig (mirror camera rig) to shoot 3D stereoscopic video, one eye might be
upside down or the mirror image of how it should look. Enable this option if you need to adjust the orientation
of either the left eye or the right eye input.

When this option is enabled, choose to flip the video horizontally, vertically or both depending on the
configuration of the camera rig.

When in 3D mode, send video to SDI output

This option determines whether the left eye, right eye or 3D muxed video is sent to the SDI loop through output
when 3D stereoscopic operation is enabled. Video adjustments are applied to 3D muxed video but not just to
the left eye or right eye.

While 3D muxed video is useful for watching or recording 3D video with a single SDI connection, some colorists
may prefer to send a single eye to a traditional CRT monitor for color grading at the same time as viewing the 3D
stereoscopic output via the DisplayPort output of HDLink Pro 3D.

HDLink Optical Fiber is easy to use because any valid video signal received by the SDI or optical
fiber SDI inputs is sent to all outputs, i.e. DVI/HDMI, SDI and optical fiber SDI outputs. HDLink
Optical Fiber automatically detects the format of the incoming signal and displays the video on
any supported DVI or HDMI-based monitor. Check the HDLink verified compatibility matrix at

www.blackmagic-design.com/support/detail.asp?techID=186

HDLink Optical Fiber has two video input connections which means that one can be used as a redundant
connection for the other in case a video feed is lost. If HDLink Optical Fiber receives valid video signals
through both of the SDI and optical fiber SDI inputs, the first signal received will be displayed on the
DVI/HDMI output and also sent to the SDI and optical fiber SDI outputs. Should the first signal be lost, the
other will immediately replace it. For example if HDLink Optical Fiber was receiving video from a distant
location via optical fiber SDI, and the link was unexpectedly cut, HDLink would automatically switch over to
the SDI video input which could be from a nearby SDI source. Similarly HDLink would automatically switch
to the optical fiber SDI source should the SDI input be unexpectedly lost.

Note: To switch between SDI input and Optical Fiber SDI input, ensure a video signal is being sent to
the desired input and then simply stop the signal on the input which you no longer require. HDLink will
automatically switch over and receive video from the desired input.

HDLink is preconfigured for you, requiring no initial setup to connect. Your HDLink will simply run without
changing any settings, however, if you would like to update the firmware, modify settings or load custom
gamma tables, then use the HDLink Utility software. This can be downloaded from the Blackmagic Design
web site support page. Check www.blackmagic-design.com/support/

HDLink Optical Fiber uses the same software as other HDLink models and shares the same software
interface for changing settings including 3D LUTs. 3D and 1D lookup tables can be applied to the DVI/
HDMI output of HDLink Optical Fiber. If HDLink Optical Fiber is configured to send lookup tables to all
video outputs, the lookup tables will be applied to both the SDI and optical fiber SDI outputs in addition
to the DVI/HDMI output.

DVI-D monitors are shown in most of the connection diagrams shown for this HDLink model. An HDMI
display can be used in all cases except for 2K monitoring as HDMI displays do not have sufficient resolution
to display a full 2K image. HDMI displays are best for use with HD720p50 as most DVI displays do not
support this format. The included DVI-to-HDMI adapter can be used to attach an HDMI display to the DVI
output of HDLink.

HDLink Optical Fiber provides SDI and optical fiber SDI inputs which can be used for standard definition
SDI, HD-SDI 4:2:2, 3 Gb/s HD-SDI 4:4:4 video or 2K film.

The fiber optic module, included with HDLink Optical Fiber, is a standard SFP transceiver module which
includes an LC connector port for attaching fiber optic cables. While other kinds of optical connectors exist,
the SMPTE standard for Optical Fiber SDI specifies that LC type optical fiber connectors be used and this
makes it easy for all SMPTE compliant optical equipment to connect together.

The consumer level analog audio outputs are fully compatible with a wide range of consumer HiFi
equipment and are perfect for monitoring of stereo audio or even up to 6 channels of audio. 2 channel
audio output via HDMI is provided for maximum compatibility with HDMI TVs and monitors.

Troubleshooting

Why are there thick black borders around my video?

Most HDMI displays automatically scale video to fill the screen enabling PAL or NTSC video to automatically
scale and fill a high definition display so you should not encounter thick black borders around your video.

By contrast, DVI and DisplayPort displays rarely provide scaling. HDLink Utility provides an option named
Scale video to fill larger display. This option enables current HDLink models to scale smaller video formats
to fill larger DVI and DisplayPort displays and avoid thick black borders around the video.

Why do circles appear elliptical or egg-shaped via HDLink in standard definition?

HDTV uses square pixels for display as does your DVI-D/DisplayPort based computer monitor or HDMI
display. SDTV uses rectangular pixels for display which is different to your computer monitor. When HDLink
is used to view standard definition video, and is set to scale video as 1:1 direct pixel for pixel, circles will display
egg-shaped.

If you want the standard definition picture to look as it would on an old CRT display, launch the HDLink Utility
and select the 4:3 Aspect ratio scaling option for standard definition video. This scaling option will scale the
standard definition video to make it appear normal on an LCD display and circles will look like circles.

HD720p50 support

All models of HDLink support the HD720p50 standard. However there are very few DVI-D or DisplayPort
monitors which support this standard. Most new HDMI-based monitors and TVs purchased in PAL countries
now include 720p50 support and should work well with any HDLink.

Strange colors on display

HDLink automatically prevents illegal YUV colors from being displayed on your LCD monitor when
converted to the RGB colorspace. Enabling the option Scale to view illegal YUV colors will scale illegal
YUV colors into the viewable quantizing range on an LCD monitor. This will cause YUV SDI video to be
incorrectly displayed with black colors appearing higher than normal and white colors lower than normal.
Ensure this setting is disabled after use.

This setting is available from the

HDLink Utility>Preferences menu option in both Mac OS X

and Windows.

HDLink Settings can scale video to eliminate black borders
and display SD video in a traditional aspect ratio

Why doesn’t my monitor display video with HDLink?

If your monitor specifications are nominally adequate for the video formats with which you work, but
your monitor does not display video from HDLink, try the preference to override the monitor’s preferred
EDID settings.

Every monitor with DVI-D, HDMI or DisplayPort connections should include an EDID chip which provides
information about the attributes of the display and which video formats it should support. HDLink
interrogates the EDID chip and uses this information to present video on the display. If the EDID information
is not present or is invalid, then HDLink cannot automatically display video correctly.

In this situation:

 Connect HDLink via USB to your Mac or PC.
 Launch HDLink Utility and choose HDLink Utility>Preferences
 Enable the preference named “Override Monitor’s Preferred EDID settings”.

HDLink will output video at its native frame rate and ignore the preferred timing information supplied by
the monitor’s EDID chip. This will usually overcome the problem and allow HDLink to successfully output
video on uncooperative monitors.

Why can’t I see DVI or HDMI video on the DisplayPort output of my HDLink Pro 3D?

HDLink Pro 3D supports DVI and HDMI displays via third party DisplayPort adapters and cables.
While testing HDLink Pro 3D, we have found some DisplayPort to DVI/HDMI adapters and cables work
perfectly but others show no video.

If you have verified your DVI or HDMI monitor is working fine, but you cannot see video when connected
to HDLink Pro 3D, we would recommend trying a different brand of DisplayPort adapter or cable.
We have found the MonoPrice brand of DisplayPort adapters to be reliable during our testing.
The models we have used are:

 DisplayPort male to HDMI female adapter, product ID 4826
 DisplayPort male to DVI female adapter, product ID 4827

The Override Monitor’s Preferred EDID settings can be
accessed by choosing Preferences from the HDLink
Utility menu.

Why does my HDLink Pro 3D output show lots of green color with 3D Stereoscopic video?

If you are working with 3D Stereoscopic video, and your left and right eye cameras are out of sync, you will
often see half of your video image replaced with green color. This green image will appear on both the
monitor attached to the DisplayPort output of your HDLink and also to the 3D Muxed Video on the loop­through SDI output.

The first three images, on the left of this page, show how this problem will present itself depending upon
which 3D stereoscopic output format has been chosen in the HDLink Utility. The last image shows the
correct image with no unexpected green color.

This problem is easily overcome by attaching a sync generator, to both cameras, such as the Mini Converter
Sync Generator or OpenGear Sync Generator from Blackmagic Design. The sync generator should support
high definition tri-sync signals.

Why does my HDLink Pro 3D output show lots of green color with traditional non-3D video?

Unless you are working with 3D Stereoscopic video, make sure that the setting “3D Stereoscopic”
is disabled.

If “3D Stereoscopic” is accidentally enabled, you will often see half of your video image replaced with
green color when working with traditional non-3D video. This green image will appear on both the monitor
attached to the DisplayPort output of your HDLink and also to the 3D Muxed Video on the loop-through
SDI output.

The first three images on the left of this page show how this problem will present itself depending upon
which 3D stereoscopic output format has been chosen. The last image shows the correct image with no
unexpected green color.

This problem is easily overcome as follows. Open the HDLink Utility, click on the 3D tab and disable the
option named “3D Stereoscopic”.

3D Stereoscopic Side by Side enabled

3D Stereoscopic Line by Line enabled

3D Stereoscopic Top and Bottom enabled

Blackmagic 2K Format – Overview

The latest Blackmagic Design products use the new
3 Gb/s SDI video, which allows twice the data rate of
traditional HD-SDI video. We thought it would be a
really nice idea to add 2K film support, via this new
3 Gb/s SDI technology, so we could simplify feature film
workflows. With the popularity of Blackmagic Design
editing systems worldwide, now thousands of people
can benefit from a feature film workflow revolution.

This information includes everything product
developers need to know for building native 2K SDI
equipment. Of course, all Blackmagic products can
be updated, so if the television industry adopts an
alternative SDI-based film standard, we can add
support for that too!

Using HDLink Utility

34

After running the HDLink software installer, a USB driver will be installed on your system and the HDLink
Utility will be added to the your Applications or Programs folder. To use the HDLink Utility you will need to
connect HDLink as follows.

1. Connect the 5 volt HDLink™ power supply. The red power light will turn on.

2. Connect a USB cable between HDLink and a USB 2.0 port on your computer.

3. The red power light will flash indicating the USB has been connected.

4. Open the HDLink Utility and the settings should be adjustable. If they are ‘grayed out’, it indicates your
computer is not communicating with HDLink

™

. In this case, check the USB connection or try another

USB connection on your host computer.

5. If your version of the HDLink Utility contains newer firmware than is currently installed on the HDLink

™

convertor, you will be prompted to update the firmware. You must allow the firmware to be updated
before you can use this version of HDLink Utility to configure the HDLink

™

convertor. Select ‘download

firmware’ and, after a short delay, the firmware will be updated.

6. Once the firmware has been updated, it is important you unplug both the USB and power cables from
HDLink

™

, wait 5 seconds, and then plug in the power and then USB cables in that order. This ensures

the HDLink

™

is reset correctly.

7. You can make changes to red, green and blue, lift, gamma and gain settings on HDLink

™

, and import

custom gamma tables. Changes to settings can be seen on the HDLink

™

DVI-D output in real time

allowing accurate setup.

8. Gamma tables are loaded into HDLink

™

at power up and so HDLink™ needs to be restarted if new tables

are loaded. It is important to unplug both the USB and power cables from HDLink

™

, wait 5 seconds, and

then plug in the power, and then USB cables in that order. This ensures the HDLink

™

is reset and the

gamma tables are loaded into the HDLink

™

video path correctly.

9. Other settings at the bottom of the HDLink Utility window are updated immediately and don’t need
HDLink

™

to be restarted.

The HDLink Utility interface is the same on both Mac OS X and Windows platforms. Any features that are
not applicable to your HDLink model will be grayed out and inactive.

Lookup Tables (LUTs)

35

HDLink supports the use of LUTs to adjust the appearance of video on your monitor. Lookup tables can be used for
standard definition and high definition video.

1D LUTs are useful for making quick adjustments to a video image but any adjustments to color will also affect
brightness. They are often used when working with log video so that the image can be displayed on screen as
normal linear video. Built-in 1D LUTs are provided for log to linear conversion when playing video captured from
Panasonic Cinegamma

™

and Viper Filmstream™ cameras. 1D LUTs are supported in all HDLink models.

How to use Lookup Tables in HDLink

Connect HDLink to your computer with a USB cable.

Launch the HDLink Utility from your Applications folder in Mac OS X or from Programs in Microsoft Windows.
The HDLink interface should immediately be visible and adjustable. If the interface does not appear to be “active”,
check the USB connection, try another USB cable or try another USB port and it should become active.

The lookup table interface in HDLink Utility can be adjusted using a method similar to that used for image
adjustment with the Curves feature in Adobe Photoshop

™

. The horizontal axis of each graph represents the
original color input values and the vertical axis represents the new color output values. When first opened, each
lookup table displays a straight diagonal line because the color values have not yet been changed.

Changes made to the lookup tables can immediately be seen on a monitor attached to the DVI/HDMI output of
HDLink. Changes are saved to the HDLink hardware by clicking the Download button so that you don’t need to
leave HDLink connected to your computer via USB. Lookup tables can be reset to original values by clicking the
Reset Unity button and this effectively disables the lookup tables. Click the Download button again if you wish
to save the original values.

Importing and exporting 1D LUTs

All HDLink models can import 1D LUTs. The 1D file format is any tab-delimited text file with red, green and blue
values for each record and the first line (title line) is skipped. Lookup tables need to be 1024 records long with
the first line reserved for the title line. Check out the sample 1D lookup table accompanying the HDLink software
installer. 1D lookup tables can be created in a spreadsheet program and then must be exported to a ‘tab separated’
text file prior to being imported in to HDLink Utility. Click the Load Table button to load lookup tables.

1D LUTs can also be exported from HDLink in the same text format mentioned above. Both 1D LUTs created with
the curves in the lookup table interface, and 1D LUTs imported from text files, are exported from HDLink in the
same text format. Click the Save Table button to save lookup tables.

The 1D LUT text file format is fully compatible with the following Blackmagic Design products which share the
same LUT format: HDLink Pro 3D, HDLink Optical Fiber, HDLink Pro DVI Digital, HDLink 2, HDLink, Multibridge
Eclipse, Multibridge Pro (October 2007 model), Multibridge Extreme (DVI output), DeckLink HD Extreme 2 and
DeckLink HD Pro 4:4:4 (PCI-X).

HDLink Utility provides several settings for the HDLink and HDLink 2 models.

Scale SD video to fill larger DVI display.

HDLink and HDLink 2 models can scale standard definition video to fill larger DVI displays and avoid thick black
borders around the video.

1:1 Direct pixel for pixel

This option allows for precise pixel-for-pixel viewing of standard definition video. However as HDLink
uses square pixels, and standard definition video uses rectangular pixels, your video may seem squashed
and circles may appear to be egg-shaped. See the troubleshooting section of this manual for more
information.

16:9 Anamorphic aspect ratio

This option scales widescreen standard definition video to appear in the expected 16:9 aspect ratio on the
computer monitor attached to HDLink. The image will appear correctly but will no longer be presented
pixel-for-pixel.

Enable 2x Scaling of SD Video

This option will present NTSC or PAL video at double the original size on a monitor with a 1920 x 1200 resolution.
This is useful for displaying standard definition video on 24” LCD computer monitors without the video image
appearing as if it were a small postage stamp in the middle of a large black display.

Default Dual Link SDI video input

Usually when working with dual-link 4:4:4 HD-SDI video, the RGB colorspace will be used. In very rare cases, you
might need to switch this to use the 4:4:4 Y,Cr,Cb colorspace. Only change this setting if you are sure that you
need to use the 4:4:4 Y,Cr,Cb colorspace.

Default 24 fps HD format

When working with HD1080 video at 24 frames per second, it is necessary to tell HDLink whether it is receiving 24
PsF progressive video or 48i interlaced video.

Display video using blue only

This option enables blue only mode which is helpful in detecting noise in video.

Interlace simulation on DVI monitors

This option attempts to display interlaced video on progressive DVI monitors, with a similar look to traditional
CRT monitors, and to avoid video tearing.

HDLink features two, red, indicator lamps to show the operational status of the unit. The two lamps are
located on either side of the USB port. The two lamps will independently vary between being on, off or
flashing. Status information is printed on the top of the HDLink chassis.

 Both lamps off HDLink is powered off.
 Left lamp on HDLink is powered on.
 Left lamp flashing HDLink has been connected to a computer via USB.

 Right lamp on HDLink is receiving a valid SDI video signal.
 Right lamp flashing HDLink is receiving a valid dual-link 4:4:4 HD-SDI video signal.

Valid video signals supported by HDLink include HD1080, HD720, NTSC and PAL when used with a DVI­based computer monitor. HDMI monitors can also be used for display of HD1080 and HD720 video signals.
Computer video formats are generally not supported unless they coincidentally match a TV format.

1D lookup tables can be applied to the DVI/HDMI output of HDLink.

DVI-D monitors are shown in most of the connection diagrams shown for this HDLink model. An HDMI
display can be used in all cases except for standard definition monitoring. HDMI displays are best for use
with HD720p50 as most DVI displays do not support this format. The included DVI-to-HDMI adapter can
be used to attach an HDMI display to the DVI output of HDLink. Third party DVI to HDMI adapters can also
be used if your HDLink shipped before the addition of HDMI support.

HDLink provides two SDI inputs which can be used for standard definition SDI, HD-SDI 4:2:2 and Dual Link
HD-SDI 4:4:4 as shown in the connection diagrams of this manual.

The consumer level analog audio outputs are fully compatible with a wide range of consumer HiFi

Why can’t I see standard definition on my HDMI-based TV?

The HDLink and HDLink 2 models were originally designed for use with DVI displays before HDMI was
widely available. HDMI support was subsequently added with a HDLink software update which upgraded
the firmware in both the HDLink and HDLink 2 models. This firmware update exclusively supported high
definition video formats and not standard definition. If you need to monitor standard definition with these
models of HDLink, you will need to use a DVI-based monitor. If your DVI monitor supports 1920 x 1200
resolution, you may wish to use the Enable 2x Scaling of SD Video setting in order to mostly fill the display
with your video. This will minimize the black borders around your standard definition video. Blackmagic
Design has newer HDLink models which support standard definition via HDMI.

Why can’t I hear audio on my HDMI TV?

The original HDLink and HDLink 2 were originally designed for use with DVI displays and the DVI
standard does not support audio. That is why stereo, analog, RCA ports are provided on the HDLink
for low cost, 2-channel monitoring of SDI audio. HDMI support was subsequently added with a HDLink
software update which upgraded the firmware in both the HDLink and HDLink 2 models. This firmware
update exclusively supported high definition video formats via HDMI but audio must still be monitored
via the analog outputs. Analog audio can be connected to an amplifier for audio monitoring and some
HDMI-based TVs also provide analog, RCA audio inputs which makes it even easier to connect the HDMI
video and analog audio directly to the TV. Blackmagic Design has newer HDLink models which support
2-channel audio monitoring via HDMI.

Why can’t I use a 30” DVI monitor?

HDLink and HDLink 2 models connect to DVI-based monitors via a single-link DVI-D connection. This
includes LCD computer monitors with a resolution of up to 1920 x 1200 pixels. Larger monitors, such as 30”
LCD computer monitors, support higher resolutions but require a dual-link DVI-D connection. Blackmagic
Design has newer HDLink models which support 30” dual-link DVI-D LCD computer monitors as well as
smaller single-link DVI-D monitors.

Some or all video formats fail to work with a DVI display

The following information relates to the use of DVI-D displays with HDLink and HDLink 2. It does not apply
to HDMI displays used with HDLink.

1. Check the DVI-D cable

DVI-D cables are usually reliable but there are many different brands and lengths and it is wise to test
with another cable if you have poor video or no video output. Try using a good quality cable which is of a
standard length, i.e. around 6 feet or 2 meters. While long DVI-D cables are available, some work better
than others and so we recommend the use of the standard length cables, i.e. around 6 feet or 2 meters.

2. Check the specifications of your display.

HDLink supports single-link DVI-D displays. It does not support dual-link DVI-D displays such as the Apple
Cinema HD 30” display. Blackmagic Design has newer HDLink models which support both single-link and
dual-link DVI-D displays.

Next, check that your DVI-D display has an adequate resolution to support the video formats with which
you work. HDLink is designed to display video pixel-for-pixel and does not scale down to fit lower resolution
displays. HDLink supports video formats including:

 NTSC, 720 x 486 pixels
 PAL, 720 x 576 pixels
 HDTV 720p, 1280 x 720 pixels
 HDTV 1080, 1920 x 1080

Numerous 23” and 24” DVI-D displays support 1920 x 1200 resolution and these are excellent for use with
HDTV 1080 material. The resolution of these displays is high enough for HDLink to display NTSC and PAL
at x2 resolution. This is nice as standard definition video almost fills these displays at x2 resolution.

If your display is of a lower resolution than the video format with which you are working, your video will not
display correctly. For example, you cannot output 1920 x 1080 video to a 1280 x 720 display.

Similarly, a 1280 x 720 display is more than adequate to display NTSC and PAL video but it will not support
x2 display of these formats.

3. Try the EDID Manual Override settings

If you have verified that your display specifications are nominally adequate for the video formats with which
you work, then the next step is to try the EDID Manual Override settings in HDLink and HDLink 2.

Every DVI-D display should include an EDID chip which provides information about the attributes of
the display and which video formats it should support. HDLink interrogates the EDID chip and uses this
information to present video on the display. If the EDID information is not present or is invalid, then HDLink
cannot automatically display video correctly.

In this situation, connect the HDLink via USB to your Mac or PC and launch the HDLink Utility. Go to the
HDLink menu and select Preferences.

Enable the EDID Manual Override option. From the pulldown menu, try the different options until you find
one that works with your display.

If the video format is interlaced, you should only select an Interlaced Display option.

If the video format is progressive, you should only select a Progressive Display option.

An override mode outputs video at a different frequency to the incoming video signal. For example, if you
were to use the Force 5:2 Interlaced Display on PAL (25 Hz) video, you would need to multiply the video
input frequency by the force factor to calculate the video output frequency, i.e. [25 Hz x (5 ÷ 2)] = 62.5 Hz.
Therefore the HDLink would output 62.5 Hz. In the case of some displays which do not work with PAL video
rates, forcing the HDLink output to 62.5 Hz will often allow PAL video to be viewed on the display.

Please note that if you are using more than one video format, e.g. 1080i50 and 1080i59.94, your monitor
might require that you use different EDID override modes for the different video formats.

The EDID Manual Override settings are not available for use with newer models of HDLink as this process
has been automated and so is no longer required.

HD720p50 support

HDLink and HDLink 2 both support the HD720p50 standard. However there are very few DVI-D monitors
which support this standard. Most new HDMI-based monitors and TVs purchased in PAL countries now
include 720p50 support and should work well with HDLink.

The EDID Manual Override settings can be accessed by
going to the HDLink Utility menu and choosing Preferences.

Do I have a HDLink or HDLink 2 model?

To check if you have a HDLink 2, connect the HDLink unit via USB and then launch the HDLink utility.
The title bar of the HDLink Utility will report either HDLink 2 or HDLink. There are some minor internal
differences between the two models and HDLink 2 can also adjust for the difference between rectangular
standard definition pixels and square pixels used on LCD computer monitors.

Why do circles appear elliptical or egg-shaped via HDLink in standard definition?

HDTV uses square pixels for display as does your DVI-D based computer monitor. SDTV uses rectangular
pixels for display which is different to your computer monitor.

HDLink is primarily designed for display of HDTV. It uses square pixels and maps them perfectly, pixel for
pixel, on to the screen.

HDLink can also be used for SDTV monitoring but there are some technicalities related to the fact that
HDLink is displaying square pixels whereas standard definition uses rectangular pixels and that is why your
circles may display egg-shaped.

The following solution exists for HDLink 2 units but not the original HDLink.

If you want the standard definition picture to look as it would on an old CRT display, download and install the
latest HDLink software from the software downloads web page at www.blackmagic-design.com/support/
software/. After installing this software and updating the firmware on the HDLink, launch the HDLink Utility
and select the x2 scaling option for standard definition video. This scaling option will both double the
size of the video and scale the standard definition video to make it appear normal on a 1920 x 1200 pixel
display. Circles will look like circles.

To check if you have a HDLink 2, connect the HDLink unit via USB and then launch the HDLink utility.
The title bar of the HDLink utility will report either HDLink 2 or HDLink.

Strange colors on display

HDLink automatically prevents illegal YUV colors from being displayed on your LCD monitor when
converted to the RGB colorspace. Enabling the option Scale to view illegal YUV colors will scale illegal
YUV colors into the viewable quantizing range on an LCD monitor. This will cause YUV SDI video to be
incorrectly displayed with black colors appearing higher than normal and white colors lower than normal.
Ensure this setting is disabled after use.

This setting is available from the

HDLink Utility>Preferences menu option in both Mac OS X

and Windows.

1:1 direct pixel for pixel scaling of standard definition video is
technically correct but may make SD video appear squashed.
Enabling 2x Scaling with HDLink 2 models will provide the
video with a normal appearance when using a 1920 x 1200
resolution monitor.
