ARD
digitizes monitor signals with a pixel frequency up to 270 MHz. The software
video
is
pre-configured for displaying most common VESA-timings.
Please, refer to
for all pre-configured timings
(presets).
Since most monitor signals differ slightly from the VESA-timings, the user can adjust the pre-configured modes to
the provided monitor signals. Also additional timings can be entered and stored as new presets.
Usually the auto-selected preset of the default preset file
rgb3010.prs
has to be individually adjusted. In order to
create your individual user preset find out resolution and refresh rate of your graphic card and set up a test pat-
tern.
