HD 6950 Eyefinity Screen Tearing

[Davido]

So I recently upgraded to a HD 6950 to run a single eyefinity setup with my 2x Dell 2407wfp, and 1x L246WP-BN monitors. I was previously using a Accell displayport to dvi active ATI certified adapter with a HD 5770 video card. I was running eyefinity with no issues whats so ever. Since I've upgraded to the HD 6950, I had to buy a mini displayport to displayport adapter because the HD 6950 only supports mini displayports. My left and right monitors have a slight tearing issue when I'm playing games. I'm not sure if the extra adapter might be causing this issue. Any suggestions?? Thanks in advance!


Below are the two adapters I'm currently using,

I have pretty much the same setup and what i ddi to get rid of tearing was move the display port monitor to my far right (3rd monitor) then set the DVI monitors as my defaults in ATi control Panel, then in the control panel turn on triple buffering. When playing a game turn on V-sync and that should solve your problems. I still notice the occasional tear but nothing you can do because it happens because you are using a mix of outputs (DVI, DP)

Hey Davido, I wonder if my issue is similar or applicable?

I've got tearing on my center monitor with the adapter provided with the card, but I'm in portrait mode, and my connection setup seems to be the opposite of yours. I'm not sure why there'd be an issue due to the adapter since it should just be passive as far as anything I've read says.

warped: your question has been answered in this thread and yours you posted, along in other threads. It is because you are using different outputs for example 2 DVI then 1 DP. Tearing is barley if noticeable in landscape but if you use portrait it is much more noticeable. You can try so of the fixes posted in this thread and others but as of now there is no fix really for portrait it is a known problem just search around. Put everything back to landscape if its a problem for you

It's a connector issues, I'd look into getting an asus DCII 6950 or 6970 which has four DP outputs. I connected those via DP cables to monitors with DP outputs and the tearing is gone. Otherwise you could wait for those MST hubs to come out, but they are supposedly gonna be ~$150.

So there's nothing wrong with the accell mini displayport to displayport adapter? So does anyone know instead of using tdapters if I just bought an accell mini displayport to dvi active adapter, if that might solve the issue? I'm asking this because I used the same exact setup on a 5770 a there were no issues what so ever, but I only used one adapter.thanks for the responses

I wouldn't clarify any of the answers definitive but thanks for your input. I'll keep investigating.
