Oh ffs, you really don't have the first clue.
Right now I'm using a CTX 21VL; At the bottom of my monitor are 4 small buttons and a large one.
ESC UP DOWN ENTER - POWER
Press Enter and you go into the Menu Mode:
Status - Displays Current Resolution (1280x1024), Render Speed
H:64.3KHZ V:60.5HZ
I press down one and I have a Picture menu. When my monitor goes into a resolution where i becomes squashes or stretched it is because the H: KHZ is out of sync, and so you have to adjust you monitor to compensate for it. This is where you do it.
In the Picture menu are 4 Controls, H/V-Position, H/V-Size. The monitor remembers these when you exit, so really if you have a factor set one you should never need to touch these apart from for minor adjustments for certain cards.
it should have 1.33 (4:3) at H/V-Size 50,50 and 1.20 (16:9) at 60,60 normally.
But you'd adjust these to personal tastes...
Of course if your getting around H:55KHZ or less this will look stretched because your monitor is not ACTUALLY capable of that given resolution.
No matter what you set your system to your Monitor itself has to be capable of <60KHZ refresh speed at that resolution. Else you will get a stretched look, you can always offset this; but sometimes when there just isn't enough speed for it there is nowt you can do about it.
Apple's Montiors all have a similar menu system, tucked underneath the main frame; but also accessible from within MacOSX Graphics Controls.
