I used to have this worry as well as my CRT monitor burned recently. Since from threads some say that LCD optimum resolution was not good due to video card limitation.
My system is win XP, and CRT was running at 1064x768 display. After consulting few others , my input is that it depend on the existing graphic support. Mine was onboard intel display chip as my video card konked out even earlier. Since my CRT was running fine on said resolution I expect the same for the LCD.

Went to PC fair and bought an AOC F22 monitor. Decided on AOC due to its emphasis on quality (0 dead pixel warranty vs samsung 7 dead pixel).
Samsung 2243sw+ was tempting at RM578 but dont like the stand. The AOC F22 had an apple feel to it with an interesting picture frame stand which is much more stable.

Hooked up and give it a go, and to my delight, the monitor auto setup it self to find a working resolution and as expected used the 1064x768 for destop display supported by the graphic chipset. I had tried some tests including running games on different resolution and the monitor cope and changed accordingly. And for movies there is the option to set 16:9 aspect which improve screen size.

The only thing I noted of is that widescreen does stretch websites and photos native on 4:3 aspect. Believe this is a widescreen problem. (any comments to address this).

Believe its i915 .
I would say native resolution 1064x768

Thanks.. was guessing it was the resolution as well.. wonder if there is a lesser 16:9 resolution to use instead of 1920x1080.

Just that when looking for display settings, i cant find 1920x1080. So it must be the graphic card not able to support.
