Recently I switched to the new monitor and graphic card - DELL U2312HM and GeForce GTX 550 Ti. I have problems with screen tearing, like in this picture from Wikipedia:
Usually it is somewhere in upper part of the screen. Mainly happens in videos (in flash videos tearing heavier). In games all fine, except in-game videos (sometimes even videos built on game engine), but gameplay itself is clear, even in very fast actions.
Connection with DVI.
Problems both in Linux (Debian GNU/Linux, openSUSE 12.1, Linux Mint 13) and Windows (Windows XP, Windows 7), with various driver versions. 1920x1080, 60Mhz.
How can I resolve this?
UPD: Ok, Compiz with anabled VSync have resolved problem on Linux Mint, tearing now much rarer and almost non-fixeable by eye. Though it works with Cinnamon pretty bad. Anyway, It would be nice also to figure out, how to fix it in Windows XP - VSync enabled in NVIDIA panel, maybe it must be enabled somewhere else?
UPD2: I have tested this monitor with another computer. There is tearing too. Could it be hardware fixable problem? Or maybe problem with electricity? Because there is heavy tearing even in window-dragging and every enough wide horizontal animation. I do not think that this is because of 60mhz - there is some "tears" even if I just slowly scroll down browser window with the middle mouse button. Also, one month there was absolutely no tearing in movies with VLC. But then it returned. So, maybe this is because bad electricity? I read that it can be because of grounding, there were advice to bend out metal things of electricity socket or surge protector - but I am not sure that it is safe.
