Its been a while since this topic has been posted on. My problem is similar, not completely the same, however possible solutions to this problem may help with my other screen tearing problems.
My Current Specs are:
CPU Type DualCore AMD Athlon 64 X2, 2200 MHz (11 x 200) 4200+
4GB DDR2-800 RAM
nVIDIA GeForce 8800 GT OC - GPU: 650 MHz, Shader: 1625 MHz, Memory: 950 MHz, Memory: 1024 MB
Dual Screening With:
Compaq S900 - 19" CRT Running at 85 Hz
LG L225W (Digital) - 22" LCD Running at 60 Hz - 5ms
I currently have Vertical Sync Forced on in Nvidia Control Panel, and Triple Buffering on in the same application.
I have all my drivers updated fully (my bios is not, though im not sure if that would affect anything).
I however still get screen tearing on both monitors, this happens regularly no matter the size of the movie, I generally only play avi files.
This also happens in some games, specifically CS:S, but does not increase substantially when i run both a movie and game at the same time. Vsync and Triple Buffering helped reduce the amount of screen tearing, having only one monitor also does this, however I require 2 monitors, wondering if anyone has any ideas on how to remedy this problem (not just software, but upgrading of hardware) it would be much appreciated.
