Making a screenshoot with the print key, it results the resolution of 1280x800 O_o
But the monitor is a 1200x800!!!
So the column at the right side is the 80px difference beetween 1280 and 1200, and the part of screen that displays q3 is exactly 1200px wide.
yes, 1200x800 is the native resolution for my LCD.
About the solution, I already read the page, is the same solution I used (knowing consolle commands in q3, it's obvious), but my problem is different, nevertheless the wide resolution is accepted, the image don't fit the screen!
I tried Q3 on my notebook (16:10 widescreen 1200x800) using settings for custom resolution.
The result is a 4:3 image (or about 4:3) with a strip of faded desktop as a vertical bar on the right side.
But Quake see the resolution as 1200x800, as screenshoots demonstrate ...
