I am encountering an issue with my monitor when my monitor settings (both in video games and the Windows settings) are set to a resolution of 1600x900 and a refresh rate of 60 Hz. The issue is the resolution will be wrong, certainly not 1600x900. There will be a thick black bar at the bottom of the screen at the picture is stretched to the right of my monitor. When I press the button on my monitor to display info, it displays the resolution as set to 1280x960, rather than the normal 1600x900.
I've found that switching my refresh rate to 59 Hz allows the program (or Windows) to have a normal 1600x900. So basically my problem would be fixed, but not every game I have allows you to change the refresh rate. Could this be an incompatibility with my video card, as this issue did not occur with my old computer which had a different video card.
My monitor is an Acer P205H and my video card is a Nvidia Geforce GTX 560 Ti. I am using a dual-link DVI-D cable to connect them.
Thanks for all your help,
