Currently connected with VGA, tried with DVI - same results.

Situation: Purchased Monitor yesterday and replaced 17.5" MAG LCD monitor
which displayed normal ar resolution od 1280 x 1024.

New monitor is set to it's native resolution of 1400 x 1040. Display is
grainy and pixelated as if contrast is high and sharpness is too sharp. I
have played with all settings on the monitor to no avail. I have tried
windows display settings as well as NVIDIA control panel - still no fix.
Lower resolutions display as horribly blurry. I have installed and
uninstalled drivers after each attempt to resolve, such as changing my BIOS
and installing drivers.

Take particular note of how radio button appears in a3.jpg

I do have cleartype enable as well as Vista Aero.

Please suggest a fix to this problem.. the current display is extremely
harsh. Thank you so much in advance.
