There are several things you should know / do in order to test you monitor / video card:
3DMark Vantage is a PC benchmark suite designed to test the DirectX10 performance of your graphics card. A 3DMark score is an overall measure of your system’s 3D gaming capabilities, based on comprehensive real-time 3D graphics and processor tests.
Note that you can test your graphic card with every 3D program (mostly, 3D mark will be more useful for that purpose)
RivaTuner is a complete powerful tweaking environment, providing you everything you may need to tune NVIDIA GPU based display adapters. The widest driver-level Direct3D / OpenGL and system tuning options, flexible profiling system allowing to make custom settings on per-application basis, both driver-level and low-level hardware access modes, unique diagnostic and real-time hardware monitoring features

Try rolling back to a previous set of drivers if you just updated. Or try a reboot.
The scientific way: try another monitor to see if the default is in the graphical card. (That supposes you have a spare monitor, of course). – Gnoupi – 2010-07-12T09:28:46.990
