4.2.2 Procedures for Selecting an HDMI Resolution and Frame Rate

The procedures below describe how to select the resolution in HDMI.
Note: You can create your own custom formats using the Quantum Data Format Editor. These procedures are

described in Creating and Using Custom Formats, EDIDs and Bitmaps.
When you make a physical connection to an HDMI HDTV, a hot plug event will occur. There are two modes the

780 can be set in when testing HDMI sink devices that determine how the 780 responds to this hot plug event:

1) Hot plug formats On; 2) Hot plug formats Off.

When hot plug formats are On and a hot plug event occurs, the 780 will read the EDID of the display device
connected to its output port. It will then automatically configure the list available signal types (resolutions and
frame rates) to only those supported by the HDMI sink device. The 780 will also be configured to output the

signal indicated in the EDID as the “preferred” timing. The preferred timing is highlighted in green following a

hot plug event.
When hot plug formats are Off, the 780 will display all viable HDMI formats for the HDMI interface whether they

are supported by the display or not.

1. Select the Preferences from the 780 top level menu. Navigate to the second page by touch selecting the
More… key.

780 Handheld Test Instrument – User Guide Page 18

May 15, 2012

Revision A28

2. Select the Hot Plug Formats mode to On or Off as desired. Refer to the screen above.

3. Touch select the interface button (left button on the bottom panel). Refer to the figure below.

For the HDMI interface, you will set the Color Space, sampling mode, Bit Depth and Format Type.

4. Touch select the resolution and frame rate (middle button on the bottom panel). Refer to the figure below.

780 Handheld Test Instrument – User Guide Page 19

May 15, 2012

Revision A28

For the HDMI formats, there are color codes that are applied to the Resolution and Frame Rate selections. The
following is a summary of their meaning:

 A Resolution or Frame Rate with white lettering but with no outline – a Resolution or Frame Rate that

appears in the EDID and has a short video descriptor associated with it.

 A Frame Rate with green lettering and with white outline – The Frame Rate that is currently selected.
 A Frame Rate with red lettering but with no outline – The Frame Rate is not supported by the EDID for

that Resolution.

 A Frame Rate(s) with green lettering and with white outline – The Frame Rate along with the currently

selected Resolution that is the “preferred” timing.

 A Frame Rate with black lettering but with no outline – The Frame Rate is not supported by the standard

for the selected resolution.

Note: When you make a physical connection to an HDMI HDTV, a hot plug event will occur. If Hot Plug
Formats is enabled on the Preference menu, when the hot plug event occurs, the 780 will read the EDID

of the display device connected to its output port. The output is automatically set to the preferred timing

3D Color Ramp

Application: This is a 3D
pattern used to test 3D color
uniformity and crosstalk or
extinction ratio.

No variants

Description: There are 4 pairs of horizontal color bars. Each bar
depicts a color gradation from red to purple; two from left to right
and one from right to left.

Method – Color uniformity:

1. Close left eye to view image from right eye.

2. Assess the color gradation on each bar.

3. Close right eye to view image from left eye.

4. Subjectively compare the images to assess color

uniformity.

Method – Crosstalk (extinction ratio):

1. Close left eye to view image from right eye.

2. Verify that the bottom bar is extinguished. The extent to

which the bar is not extinguished represents the amount
of crosstalk.

3. Repeat for a test of the left eye

3D Cross Talk

Application: This is a 3D
pattern used to measure the
crosstalk (extinction ratio) for
frame packing, top and bottom
and side by side 3D format
structures.

No variants

Description: This image is divided in two sections with four rows of
16 white boxes each. The top section is for testing with the left eye
open. The bottom section is for testing with the right eye open.
The background area surrounding the boxes is a series of
grayscale ramps. The ramps begin at 100 IRE and transitions to
50 IRE at the left end of the fourth row of each series.

Method – Calculating percent crosstalk:

1. Close right eye to test the left eye using the top section.

2. Check the visibility of the boxes. Any deviation from

black indicates crosstalk.

3. Assess where the box and its background blend such

that they are not distinguishable.

4. Calculate the degree of crosstalk as a percent by

counting the number of boxes (from the beginning of the
series to the box identified in step 3) and divide that by

127. Example if the 20th box blends with its background,
the crosstalk would be 20/127 * 100 = 15.7%

5. Repeat with the left eye closed to test the right eye.

4.5 Rendering 3D Test Patterns on an HDTV

This subsection describes how to render 3D test patterns on an HDTV. The 780 supports Side-by-Side, Top­and-Bottom and Frame Packing (for both interlaced and progressive timings) 3D format structures.

4.5.1 Configurations for Rendering 3D Bitmaps on an HDMI Sink Device

Typically you will render 3D bitmap images with the 780 directly connected to an HDTV. This configuration is
shown below:

780 Handheld Test Instrument – User Guide Page 30

May 15, 2012

Revision A28

4.5.2 Procedures Obtaining 3D Bitmaps on HDMI Sink Device

Use the procedures below to render 3D bitmap images on an HDMI sink.

1. Follow the procedures provided above to enable the HDMI output as the Signal Type.

2. Obtain 3D bitmaps. You can obtain 3D bitmaps in three ways:

 Develop your own 3D bitmaps.
 Sample 3D bitmaps from the Quantum Data website (www.quantumdata.com/downloads).
 Generate 3D bitmaps from your own stereoscopic image pairs using the Quantum Data 3D Bitmap

Conversion Tool available from the Quantum Data website (www.quantumdata.com/downloads).

3. Transfer your 3D bitmaps over to the 780 using the procedures described in Importing Custom Bitmaps.

4.5.3 Procedures for Rendering 3D Bitmaps or 3D Test Patterns on HDMI Sink Device

1. Select a format that is suitable for rendering 3D images such as 720p60 and 1080. Use the procedures
above Procedures for Selecting an HDMI Resolution and Frame Rate.

If you have used the Quantum Data 3D Bitmap Conversion Tool, there is a naming convention for the 3D
bitmaps which also provides the required format for each specific bitmap.

2. Touch select 3D Output option from the top level menu shown below.

780 Handheld Test Instrument – User Guide Page 31

May 15, 2012

Revision A28

The following screen will appear:

3. Select the 3D mode (Side-by-Side, Top-and-Bottom or Frame Packing) and then select the subtype and
Left/Right options (if applicable).

4. Select the 3D bitmap image from the Test Pattern list.
Note: You will have to make sure that the 3D bitmap you use matches your selection of 3D formats and

timing (resolution). In the example above, a 3D Frame Packing bitmap is selected for 1280 x 720.
Therefore you have to make sure that you select that specific timing (i.e. 1280 x 720) and that specific 3D
format structure (Frame Packing).

4.6 How to Scroll a Bitmap Pattern

This subsection describes how to scroll bitmaps on your 780

4.6.1 Guidelines for Scrolling Bitmaps

There are two ways you can animate (move) a bitmap image: 1) image shifting (scrolling); 2) panning. You can
shift or scroll a bitmap image that you have imported into the 780 by modifying the X and Y parameters or by
dragging and panning. When you use the X and Y parameters, you are limited to linear scrolling. With panning
you can move the image in non-linear motions.

780 Handheld Test Instrument – User Guide Page 32

May 15, 2012

Revision A28

You can only scroll bitmaps whose overall pixel resolution is smaller than the resolution of the active format and
you can only scroll them within the bounds of the resolution of the active format. You cannot scroll the standard
test patterns in the 780.

In order to scroll a bitmap the name of the bitmap has to be “zp.bmp.” But you can scroll any bitmap. You just
have to make sure that you have named it “zp.bmp” (without the quotes). The zone plate bitmap is the only
bitmap that comes standard with the 780.

4.6.2 Procedures for Scrolling Bitmaps

Use the following procedure to scroll your bitmaps.

1. Touch select the desired bitmap image, e.g. Zone Plate image from the list of video patterns.

2. Double touch select on the Zone Plate bitmap to access its options.
The Zone Plate Options menu appears:

3. Specify the Horizontal Movement by touch selecting the appropriate setting Slow, Medium, Fast.

4. Specify the Vertical Movement by touch selecting the appropriate setting Slow, Medium, Fast.
The pattern will begin to move around the raster of the display in accordance with the horizontal and

vertical settings. To halt the motion, touch Stop for either or both of the Horizontal Movement and
Vertical Movement.

Revision A28

4.7 How to Pan a Bitmap Image

This subsection describes how to pan bitmap test patterns on your 780

4.7.1 Guidelines for Panning Bitmaps

There are two ways you can animate a bitmap image: 1) image shifting (scrolling) 2) panning. Here are the
rules and capabilities:

 You can pan bitmaps whose overall pixel resolution is greater than the resolution of the active format only

to the extent of the difference between the resolution of the bitmap and the resolution of the format you
currently have selected.

 You can pan bitmaps whose resolution is lower than the active format but only within the range of the

excess space in the raster. You cannot pan the standard test patterns in the 780.

4.7.2 Procedures for Panning Bitmaps

Use the following procedure to pan your custom bitmaps.

1. Select by double touching, the desired bitmap image, e.g. Master 1920x1080 image from the list of video
patterns (shown below).

A message will appear informing you how to scroll the bitmap.

have purchased the Network Analyzer option.

6.1 Testing Video from an HDMI Source Device

This subsection describes how to test the video on HDMI source devices.

Note: You will not obtain correct results when you test a DVI device with computer formats.

6.1.1 Connection Configurations for Testing HDMI Source Devices

The 780’s HDMI input port acts as a “reference” HDMI sink device. Therefore it enables you to emulate a
known good HDMI sink device to conduct a basic confidence test of an HDMI source device. This test ensures
that you are receiving a valid HDMI video signal by displaying the timing of the incoming signal and informing
you whether it is HDCP encrypted or not. You can run this test in three configurations:

 Source device connected directly to the 780 HDMI IN connector.
 Source device connected to the 780 HDMI IN connector through a repeater device.
 780 HDMI OUT and HDMI IN ports acting as both as a known good source and a known good sink connect

to both the input and output of the repeater device.

In all cases the 780 is emulating a sink to test an upstream source. In the third configuration, the 780 is
emulating both an HDMI source and sink. These test configurations are shown below.

6.5 Testing an HDMI Source’s Response to an EDID

The 780 HDMI IN port emulates an HDMI sink device. Part of that emulation function is presenting an EDID to
a source when a sink device is powered and hot plug is asserted. The 780 is provisioned with a default EDID
from the factory. There are two standard EDIDs available with the 780 as provided: 1) Standard HDTV EDID, 2)
Standard A/V Receiver EDID.

However you can reprovision the EDID by connecting it to a sink device whose EDID you would like to use for
testing. The 780 can store multiple EDIDs. These EDIDs can be obtained either by extracting them from an
HDMI sink device (e.g. HDTV or AVR) or by importing EDID .xml files created using Quantum Data EDID Editor
tools. For procedures on importing EDIDs refer to Adding Reference EDIDs for Use in Testing HDMI Devices.

The EDID test of an HDMI source device enables you to see how a source device responds to a specific EDID
or a series of EDIDs. The EDID could be a known good EDID or an EDID you have chosen specifically for
testing purposes.

6.5.1 Configurations for Testing an HDMI Source Devices Response to an EDID

You can run this test in two configurations: 1) with your source device connected directly to the 780, 2) with
your source device connected to the 780 through a repeater device. In both cases the 780 is emulating an
HDMI sink to test an upstream source. These configurations are shown below.
