Chapter 4, Configuring Matrox Convert DVI
Specifying your Convert DVI display modes
By default, Convert DVI supports a predefined set of common desktop
resolutions at 60 Hz and 75 Hz. This is to ensure that Convert DVI functions with
most DVI monitors/devices. The default 60 Hz resolutions provide optimal
results for outputting video at 29.97 fps or 59.94 fps, such as NTSC and
1920×1080i @ 59.94 fps. However, you may need to change the supported
Convert DVI display modes for the following reasons:
• If the Convert DVI video output format is set to PAL, 1280×720p @ 50 fps,
or 1920×1080i @ 25 fps (see “Specifying your output settings” on page 29),
you can optimize your video output by changing the Convert DVI display
modes to support 50 Hz refresh rates.
¦NoteTo avoid display issues when changing the display modes to support
50 Hz refresh rates, the DVI monitor connected to the DVI OUT of your
Convert DVI must also support 50 Hz refresh rates. If the monitor connected
to Convert DVI’s DVI output does not support a 50 Hz refresh rate, you can
connect a video monitor or other display device to Convert DVI’s analog or
SDI outputs in order to see your Convert DVI desktop.
• If the display mode of the monitor/device that is connected to the DVI IN or
DVI OUT connector on your Convert DVI is not supported by default.
¦NoteYou must restart your computer after changing the supported display
modes for the changes to take effect.
