Any way to increase my refresh rate?

[SirDante]

21" monitor, 1152x864, 75 Hertz, Geforce2 Pro 64 mb

It won't let me go higher but the specs say it should.

The left side of the screen pulsates/flickers slightly and it's distracting. I just got this monitor. Should I return it?

Thanks.

Do you have the correct driver installed for it?

Check your cables and try adjusting the image with your controls.
