Specifying your Convert DVI display modes
¥ Tips
• Right-click to temporarily hide the selection window and mouse icon.
• If Allow clicking through selection window is disabled (see “Specifying
your region of interest settings” on page 33 ), double-click anywhere within
the selection window border to center it on your Convert DVI desktop, and
restore the window to a preset size and aspect ratio based on the current
output format. In some cases, this may result in an unsupported scaling mode
(selection window border becomes red). If this occurs, the video output will
display the last supported output until you resize the selection window so
that its border is no longer red, or adjust the output scaling (see
“Scaling and
positioning your output” on page 46 ).
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 27 ),
you can optimize your video output by changing the Convert DVI display
modes to support 50 Hz refresh rates.
¦ Note To 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.
¦ Note
You must restart your computer after changing the supported display
modes for the changes to take effect.
