Hey,

How necessary is 1:1 pixel mapping on a 24" monitor? I can't find too many with the ability, but do the ones that don't have it always stretch the image? Or can I watch HD and DVD's with black bars anyway?
 
Unless we are talking about something else, 1:1 Mapping means you are matching your source resolution output to perfectly match your display.
So for example, if you have a 1080p display, you want to send it a 1080p signal to avoid any upsampling or downsampling.
Because LCDs only have one real resolution, anything else you send them means a not so sharp picture and sometimes its quite a dramatic difference.
 
Yes, but the monitor I want to buy has a native resolution of 1920x1200, no pixel mapping. I want to watch movies without them getting stretched to fill the screen.
 
It depends on the source. If you use your PC to watch the movies then they will scale properly, as your PC will do the scaling and send the image at the 1920x1200 res. If you use a PS3 or another player, then you will most likely have stretching.
 
Nice, thanks! All I'm going to use is a pc. Does it also work with old games like Red Alert 2, because I calculated that if I manage to get them 4:3 on a 16:10 monitor the image will still be bigger than on my old 21" CRT.
