Default Screen Tearing

Whenever I play games on my pc I get constant screen tearing and it pisses me off. A lot of the times it tears with Vsync on too.

I have a HD4870 and the screen tears when I play like Borderlands, Dragon Age, COD4, etc. I have a decent CPU (e5400 OC - 3.6ghz) but I don't think the cpu has very much to do with screen tearing, does it? I lower the res from 1920 x 1280 to like 1400 x 900 and the screen still tears.

I have the latest drivers installed and I have an Asus 22" LCD monitor.

Running win 7 RC.

Any advice?

I went into the catalyst control and the refresh rate is automatically set on 60. My horizontal refresh rate for my monitor is 76hz, so I forced my video card to refresh at 75hz and then it automatically changed my resolution to 800x 600.

Vertical refresh rate is what u want. Horizontal is the speed from left to right on the monitor.

Higher Refresh rate on an LCD doesn't matter much, since it doesn't flicker. Your video card drivers might be forcing Vsync off.

You may want to consider defaulting all system clocks to default (no overclocking), including the video adapter timings. Some of the early release candidates of W7 had a number of DirectX bugs in them (Direct Draw in particular), that were ironed out in final retail.

Also, sometimes the video cable is not seated well, or the pins become oxidized over time. Cheaper cables may not be insulated against RF interference very well, which results in a forced resync/reblank of the final buffered video (causes a frame stall and the "tearing" effect).

Examine the video cable - even if it's a digital one - for damage and oxidation, bent pins or loose insulation. Try out a new cable if you have one around.

If you can test out a game on another monitor (or TV), do this as well. If you still see screen tearing, you can rule out monitor hardware and cable problems.

Thanks for the tips R, but I also should have mentioned that I use this same monitor with the xbox and don't have any tearing with it. I actually did a reset to my bios and my video card this afternoon, but it didn't seem to help much.

Monitor refresh rate? Would that affect screen tearing any?
