Hi, I'm having some weird problems, looking for any advice.

My multimedia computer I keep near the TV, for using the secondary monitor extending to my HDTV, is having some issues. It seems these have to do directly with the Radeon and the Catalyst setting program AMD Vision Engine Control Center.

I noticed I was having noticable screen-tearing when watching videos on the extended desktop's secondary monitor (the HDTV). I remember an older ATI card of mine had this problem too, and I've read about screen-tearing on secondary monitors being a problem with ATI cards.

I know there are things like maybe the TV has a different refresh rate than the LCD monitor, both are recent, the TV is 1080p. I didn't have the screen-tearing problem on that TV when using a different brand of card on a Windows 7 computer for example.

I also know Windows Vista has less robust extended desktop settings than Win7, but the extended option has worked. Anyways, to try to clear up this screan-tearing if possible I looked into a lot of online things that suggested various things in the settings, such as trying the "duplicate desktop" via ATI instead of the "extended desktop" via windows, since Vista doesn't have the duplicate option like Win7 does.

This caused problems, such as my mouse pointer becoming invisible after a while and issues like that. Though still screen-tearing on the TV. So the only option I saw to undo this duplicate thing was to click "disable" on the TV display in the ATI settings, then click "extend" to that TV again via Windows display settings.

Any ideas on how to get rid of this screen tearing when watching videos on a second monitor? Thanks. Using the latest version of drivers available for that card. (13.9)

Just trying this. I've found some tear some don't. Used Windows media centre and Media Player. Playing a DVD is perfect with WMC.

What player are you using? Is it all vids that tear?

Using a player that gives you the option to select the rederer might help. Many say MPC-HC + MadVR are the best. MPC also has an alternate sync option on renderers that support it.

The Problem with tearing on dualmonitor-setups is the issue with the timing clocks on radeon cards.

You can use a Catalyst driver , which hasnt got any Idle-Clocks OR using Ati-Tray-Tools to keep your card at the max core/memory clock, not allowing to go into any idle-mode.

The advantage is, tearing is gone. The disadvantage is that your card will be running at a steady 100%-mode even when your PC is idling -> more power consumption + higher temperature.
