Limited Screen Resolution Even if 1024X768 is set in Control Panel

[BHexed]

Have a program which needs 1024X768 screen res. This program works fine on other systems, a laptop with 15" LCD monitor, a desktop with 15" LCD monitor and a desktop with 17" LCD monitor where program was originated. All are set to 1024X768 for the display and all are WINXP Home systems.

Another WINXP Home system with an older 15" LCD monitor appears not to attain necessary resolution in that the screen is cropped on the right and the bottom even though the resolution is to 1024X768. The adapter is apparently allowing the 1024X768 res. because the setting takes via control panel. The LCD monitor should have a native 1024X768 res. but maybe not.

Anyone have any thoughts on other possibilities to explain the Problem?

Thanks.

Do you have the correct drivers for the adapter and LCD?

You could try different refresh rates and color depths too.

Thanks for your input. Have solved the problem. In Display Properties, under Advanced Settings, the DPI was set to 120DPI instead of the expected 96DPI usually set for the LCD. This was inadvertently done by someone to up font size in lieu of doing the normal selection, under Appearance settings, of selecting Large or Extra large for fonts.

I didn't know before that the DPI setting had such an effect on the LCD monitor. There's always something new to discover.

Thanks again.
