Screen shaking as refresh rate is turned up...

[VigilanteCS]

Hi,
This has really started to annoy me. As I turn the refresh rate of my screen up it almost starts shaking (look at a letter and it's moving back and forth very quickly). The moire of my monitor is set to 0. It doesn't shake at 60 hz, but 60hz hurts my eyes.
PC specs
19" Samsung SyncMaster 997DF CRT monitor
Athlon 64 3500+
1 gig Corsair XMS
GeForce 6800GT
80 gig SATA hdd
Asus A8V Dlx
Antec 550watt psu.

Does anybody know how to get rid of this? It's so annoying!

Just about all.

Can you increase the screen refresh rate a bit?

Edited --> nevermind, I've had one too many :beer: :beer: :beer:

get everest home edition and go to your monitor, and see the supported refresh rates. also, make sure you have 71.89 nvidia drivers.

Windows tells me what my monitor can support. At 1280x1024 it can do 85 Hz (which shakes the least)
