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

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.

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
