2 DVI20-Devices Overview

The DVI20-Device is an easy to use plug-and-play box that allows the use of much lower priced
DVI monitoring for SD and HD pictures. Set-up and operation are easy, and can be performed
using the HDVI-CP control utility, or the Infra-red Doremi Remote Control. To ensure that the
images look always good; Doremi has focused attention on the technical detail of the many
facets of the conversion process.

 Accurate spatial interpolation for clear sharp rendition of static images
 Advanced de-interlace processing for clear, accurate output of moving images
 Image output is automatically matched to the size of the monitor display to give optimum

results and avoid further processing

 Temporal processing for smoother frame rate conversion
 Small size, low power consumption

2.1 Devices Description

2.1.1 HDVI-20s

Doremi Labs’ HDVI-20s is a universal DVI-D converter / switcher. It converts SDI, HD-SDI, DVI­D and DVI-A (analog RGB) to DVI-D (digital RGB). It automatically detects the input scan rate

Doremi Labs

Note: According to the input(s)/output(s) available for each device, the OSD menus and remote
controller functions might not all be active for each device. For example, no SDI input setting will
be possible for the DSDI-20 device.

For clarity in this document, the OSD and remote controller functions are presented in their
entirety, while active functions might differ from one device to another.

Please refer to the table above to identify which function is applicable to each device.

2.3 DVI20-Devices Operation

On power up, the DVI20-Devices will automatically detect the input format of the selected input
and will send a message to the monitor connected via DVI requesting its EDID parameters. The
EDID parameters of the connected monitor will be used by the DVI20-Devices to determine its
output resolution.

The DVI20-Devices DVI-D output has 2 major controls: Resolution and Frequency.

Resolution:

Can be set to Auto (default) or forced to 1024x768, 1280x720, 1280x768, 1280x1024, 1366x768,
1400x1050, 1920x1080, 1920x1200 or 1080i

Frequency:

Can be set to 48Hz, 50Hz, 60Hz (default) or forced to Frame Sync.

2.3.1 Resolution

The output resolution can be set to Auto, 1024x768, 1280x720, 1280x768, 1280x1024,
1366x768, 1400x1050, 1920x1080, 1920x1200 or 1080i, using the On Screen Display (OSD). In
Auto mode, the output resolution will be set to match the monitor up to 1920x1200.

 If the EDID response of the monitor is not recognized or is higher than

1920x1200, the DVI20-Device will default to 1280x1024. In the case where this
same monitor does not support 1280x1024, the output resolution can bet forced
using the infrared remote control and without the OSD interface by using the
remote control DVI out selection.

 If the DVI20-Device DVI output is connected to a consumer TV that reports 1920x1080

interlaced, the unit will default to output 1080i.

 In case of a TV set that reports 1080i, the HDVI-20 device will output a compliant 1080i

signal and the TV will display it properly.

 XDVI-20 only:

The XDVI-20s cannot display both DVI-D and SDI at the same time - use the remote
control DVI out or SDI out selection.

Note: In case the selection is for SDI out, the displayed DVI output is not valid.

2.3.2 Frequency

The default frequency is 60Hz because it works with all displays. If your display supports lower
frequencies and if your input source is running at 24/48, 25/50 Frames/Fields per second, you
can avoid motion artifacts by forcing the output frequency to Frame Sync.

DVI.OM.000262.DRM Page 8 of 33 Version 1.4

Doremi Labs

2.3.3 DVI-A Special Instructions

Analog input sources can be noisy and jittery. We strongly recommend using the digital inputs
whenever possible. If you have to use the analog input, make sure your timing is compliant with
the CEA-861-B standard, especially for 1920x1080p @ 60 Hz. These are the Guidelines for DVI­A inputs:

1. The timing must comply with the standards: VESA or CEA

2. The Pixel Clock should be less than 165MHz

3. For 1920x1080, the timing must comply with CEA-861B that yields a pixel clock of 148.5

MHz.

4. For 1920x1200, the timing must comply with VESA or CEA, the total number of pixels
must be less than 2200 and the pixel clock must be lower than 165MHz.

The pixel clock P is equal to:

P = total_horizontal_size x total_vertical_size x refresh.

For a 1024*768 at 85 Hz:
total_horizontal_size = 1376 (1024 pixels + horizontal blanking)
total_vertical_size = 808 (768 + horizontal blanking)
refresh = 85

P = 1376 * 808 * 85
P = 94503680 Hz
P = 95.5 MHz

press the “Exit” button on the remote controller.

Note: According to the input(s)/output(s) available for each device, the OSD menus might not all
be active for each DVI20-Device.

For clarity, the OSD menus are presented in their entirety, while active menus might differ from
one device to another – each menu might also display/hide some items if they are not available
for a device.

Please refer to the table in section 2 to identify which OSD menu is available for your DVI20­Device. In the example of the DSDI-20 device, the only input available is DVI-D. So the first OSD
menu item - Input Source Selection - will not be displayed.

By default, the remote is unlocked. Paragraphs below present the OSD usage.

5.1 Input Source Selection

To enter the Input Source Selection window presented in Figure 6, go to the Input Source
Selection icon using the remote controller arrows - see Figure 5 - and hit “Select” – see Figure 1.

The Input Source Selection window allows you to choose the input format among four different

Resolution

-Auto (default): Use with all monitors up to 1920x1200. If the monitor reports a bad or
unsupported resolution, the HDVI-20s will default to 1280x1024. In the case
where this same monitor does not support 1280x1024, the output resolution can
be forced using the infrared remote control and without the OSD interface by
using the TV/Video + Number combination (see paragraph 2.3.1)

This menu can be used to reset the factory default settings of the unit. It also displays the
monitor’s native resolution, the current DVI output resolution, the current DVI output frequency,
the infrared remote control status, the current input and the firmware version. After you reset the
factory defaults, you MUST recycle power on the unit.

Note that some items might not be present for all DVI20-devices. For example, the DSDI-20
related “Miscellaneous” window would not contain “Current DVI Out Resolution”.

8 Recommended LCD Monitors Specifications

 16ms response time or less for best motion performance.

 Support for 1:1 display mode, in this mode the LCD will not scale the video and shows a

pixel-to-pixel image. (Useful when the LCD native pixel resolution is higher than
1920x1080).

 24/48 frequency support, in this mode 24 frame video can be displayed at its native

frame rate, and eliminate the need to re-process to 30 fames. (For LCDs that only
support 25/50 and 30/60 frequency the HDVI-20 can be set to re-processes the video to
25 or to 30 frames)

8.1 Note about the Viewsonic VP2290b

Because the VP2290b is a 3840x2400 monitor, the DVI20-Devices output must be forced to
1920x1200. This monitor supports Frame Sync and can be operated at frequencies as low as
24Hz. In addition, this monitor is pre-adjusted according to ITU-709 to be used as a high def.
reference monitor. The combination of the DVI20-Devices with the VP2290b creates a low cost
reference monitor that competes with CRT reference monitors that are priced over $30,000 US
Dollars.

8.2 Note about the Apple Cinema Displays

All Apple cinema displays are supported by the DVI20-Devices except for the 30”. The Apple
displays support 60Hz frequency only. Frame Sync Mode should not be set with these monitors;
the DVI20-Devices will display all input resolutions at 60Hz. Note that Apple Cinema displays
with the ADC connector will need a DVI to ADC converter.
