Hey Man,
Try Changing Your Monitor Driver to
Plug And Play Monitor then try to get the resolution up.

the pretender can u tell me how to do that

go to properties of my computer, go to hardware, click device manager,
then locate monitors, double click it, then click update driver,
then click i will search for drivers my self, just click next and click show all devices, on right it will show plug and play monitor, click that and click next.
