on your monitor? make sure your monitor supports a higher resolution (if so, make sure you have the correct drivers installed for it), then open your display settings, go to the settings tab, move the resolution slider to the right.
the slider only goes that high... i use a UniCrome GFX and it dosent have dlable drivers does this mean that it cant work? if so im fine wit it
no, he needs to install drivers that support a higher resolution. default drivers usually suck and only support the lower resolutions.
I think your monitor has to support it. If you have a super small monitor, I don't think you can run higher resolutions
