Here is my system:
core i5 750
12 gb ram
2x HD 5850 on crossfireX mode
LG monitor W2353 1080p 60hz on DVI
Samsung TV 46F7500 1080p 60hz on HDMI
I'm using a duplicate (clone) display setup. But I get a lot of tearing on both screens whey playing any kind of movie. Even in exented display I get tearing. How do I solve that?
I've tried forcing vsinc with no success.
There is another problem that should be associated: sometimes the video card (or the TV) "losses" the resolution information, as if the TV and the video card aren't able to communicate properly. I turn on the computer and the TV has drop to 640x480 and I can't change it anymore (grayed out). Also the TV is recognized as a non PNP (plug and play) monitor when this happens. I can force it to display 1080p using Catalyst Control Center (CCC) but when i restart the computer it "erases" the resolution settings as if I have connected a new TV. Sometimes it gets back to 1080p (recognizing the TV properly) sometimes it doesn't.
My video card drivers are up to date.
If I disconnect the HDMI cable from the TV **AND** the computer and connect again it recognizes the TV as it should (1080p). But after some time, for no apparent reason, it ends up "loosing" the resolution info as I said before.
I realized that the TV is "always on" for the video card, even if i turn it of. To illustrate: if i have an extended setup, my mouse continuous to disappear into the TV, even if it's turned off by the remote control. I don't know if this would be related to the problem.
I've already formatted my PC because of this.
This problem is getting me crazy. Why can't my PC, monitor and TV work all together?! Why are movies tearing so much?
Thank you guys! Any help is very much welcome.
Hum... something really interesting just happened: with the clone mode on i've set the TV as the primary/prefferd display. The tearing on both displays disappeared!! : D
The problem is that games only play full screen on the TV, even when i'ts on standby. What now? Any idea on how should this help solve the problem? Or at least lead to it's origin?
