eyefinity 6950 tearing issue

HI,
I moved from matrox triple head to eyefinity on my 3 dell 24"s. All has been just perfect with the 5870 I have. It was configured 2x dvi and 1x dp>dvi adapter.
Now I have just checked out a 6950 on my rig, same monitors, same configuration and notice a horrendous tearing on the 2 monitors connected to the DVI outs on the card. Imagine moving a box around the screen and noticing what seems like a step in the verticals. It seems as if it is lagging behind in scanning the monitor lines if you know what I mean.
The card is actually a friends who asked me to try it out to see if it is the same, it obviously is.
Moving the connectiions about makes either dvi outs ok, dp not etc etc.
Any thoughts guys?, surely someone has this issue too?
Different drivers have no effect either, all drivers removed correctly and no nvidia remnants whatsoever, total clean install.
Thankkyou

I had this issue when i was using 3 completely different monitors. The issue might be EDID. Like they may use different sync polarities for dp and dvi.

yes, but my monitors are all dell 24" same model.
The friends monitors are different makes, but same size.
The tearing happens on mine and his rigs which are totally different.
could it be the 6950 cards displaying 2x dvi 1x dp>dvi adapter?
I have a sapphire dp>dvi adapter with the 5 series card, the 6 series is using a xfx active eyefinity approved dp>dvi adapter; what do you think about trying a 2 dp>dpi adapters and 1 dvi on the 6 series?
I will have to find
a mini dp >standard dp adapter as the 6 series has only 2 mini dps and 2 dvis.
this has to be a problem eleswhere as the card is on 2 very different rigs?
The card is perfect in 3x monitors before the group is setup, once the group is setup it begins.
cheers
Help?

I have the exact same problem with my 6950. The two DVI output monitors experience severe screen tearing. The mini-DP output monitor (through an Apple active adaptor) has no problem.
My work-around has been to put the mini-DP monitor in the center and the two DVI monitors on the outsides. I notice the tearing much less in my peripheral vision (although it is still there if I focus on either oustide monitor).
All three monitors are identical (Dell 1909, 1440x900). Driver Sweeper was used to clean previous nVidia drivers.
I have a second active DP adaptor on order. When I get it, I will try two monitors on DP and a single monitor on DVI and see if that resolves the problem.

I also have the same tearing issue you guys described here. Some people are talking about it on another forum over here: http://hardforum.com/showthread.php?t=1576329
I disabled vsync in all my games and that seems to have reduced the tearing considerably. It's still there, but now barely noticeable.

Its a problem with how the 69XX series uses both DP and DVI-D. If you use both, your going to get a line/tearing effect on the monitors. There is no "fix" yet, other than either going all DP or getting some kind of hub I read about online (for about $150).
What I did was I set my HDMI and DVI monitor up first, than connected my mini-DP port (with an adapter to go to DVI-D) last, now the tearing only shows up on that one monitor. And since its not the center monitor (since that would be too noticable) and only shows up on the right monitor, its hardly noticable, especially in games. I actually have to try to find the line.
So thats basically all you can do. For now.

This is a very sad problem, I had no tearing at all on my 5870 card, but since I "upgraded" to a 6970 I got this tearing thing. Now I'm used to it, but that kind of things should never happen.
Anyway you don't need to switch connectors, you can configure your preferred display in EyeFinity settings on Catalyst Control Center. My DP monitor is on the left, so the center and right monitors are using DVI. If you put a DVI monitor as favorite monitor, both DVI monitor's won't tear, only the DP.

I'm sorry, I don't understand. What do you mean by "favorite monitor"?

Edit: After reading the post again, he's probably talking about preferred monitors. This can be set in Desktop Management -> Creating and Arranging Desktops section when in Eyefinity. Right click the monitor and click the "Make Preferred" button. I don't think this fixes the problem because I've always had my center DVI monitor as the preferred one. I still get tearing on the center DVI monitor, and not just the DP one as others have suggested.

well. yesterday I had huge tearing in Mafia 2 on my center monitor. I reinstalled windows, since I had to do that any way. after that I first connected my center and right monitor (dvi, hdmi). after that I connected my left dp monitor and now the tearing is only on the left one instead of center!
I noticed this tearing problem before, but I'm so happy that now it is only on the left one instead of the center. Don't know what exactly caused the tearing to move, but it did :) .

Not to be a pain but all you needed to do like mentioned above is change your prefered display to a DVI monitor, and only the DP monitor will display this effect. And vice versa.
Can anyone confirm if only using one DVI port, this corrects the issue?

I saw really bad lagged tearing in the top 20% or so of the screen of a 2x2 1920x1200 configuration (3840x2400) driven on a single monitor. For some reason when using the native 41Hz it had this problem but when I created a custom EDID to run at 60Hz the really bad tearing went away (now just some monitor tearing from running 60hz on a 41hz native monitor).

Man that really sucks, I was about to buy a 6970 because like a lot of people here I purchased 2 5870's last year but my experience with eyefinity and crossfire was so bad I sold 1 5870.. After that experience I will never crossfire and use multi monitors ever again.
I need a little more juice to run eyefinity and use a little AA than just 1 5870. I am shocked to see more of the same problems with 2nd gen eyefinity cards.. unfortunately this tells me the problem is probably unfixable on there part because its probably issues with the individual monitors. Hopefully the 7979 will be able to handle 5040x1050 @ 60 with AA ...
The only reason a person would or should want 2 cards is:)
A:) you have a 30" Panel
B:) Your gaming with eyefinity or surround.
And these problems make crossfire pointless if you use eyefinity. I am still pissed off about this BS.

Confirmed same problem on 6950 bios mod > 6970 - config'd like [DVI][DP][DVI]
Win7x64 is fine when spanned. After grouping, tearing is noticable when on DVI screens only. Removing v-sync from games seems to lessen the effect.
I have hope this is a software/driver issue, not hardware problem, as only happens when group.

Sapphire 6950 flashed to 6970 problem confirmed.
With the card setup, you'll have either 2xDVI & 1xDP or 2xDP & 1xDVI.
On the two monitors with like connections, make sure one of them is in the middle. When you enable Eyefinity, in the Eyefinity setup area be sure to select the middle monitor and choose "Make Preferred Display". This will keep 2 of the 3 monitors from tearing. Sadly the odd monitor out will have nasty tearing.
This is a pretty sad issue to have to deal with honestly.

Hey everyone. At the extreme danger of butting in, thinking allowed and making a fool of myself:
Can you run three dvi monitors (or 3 vga monitors) off the display port and the two minidp ports using three active adaptors to solve the issue?
Edit: I take it Ninefingers above me has my answer... I'm honestly finding it hard to find the reason why you can't do three dp outputs on the 6xxx series though (with that added 1.2 display port)? Would be grateful if someone could point me in the right direction.
Edit2: Wow. OK. Got it. :oops:

6950 flashed to 6970 - same problem, uber tearing on left and right screens, I wasn't experienced tearing issue on my 5850 before.

It's a hardware problem with out of sync timings between the DP and DVI ports. $150 MST Hub (2012?), Eyefinity 6 5870/5970 or a 6990 is the only way to fix screen tearing in 3+ setups. The 6990 maxes out at 4.
For now, you can minimize it by placing the odd-port-out on either side of your config and making one of the two common connected monitors your "preferred" monitor.
This problem has really ticked me off and I wish I had known about it before I wasted money on a pair of 6950s. I was hoping to tri-fire them for $50 more than the cost of a single 6990 but now it looks like I have to pony up $100 more per GPU and get the 6990 or wait till 2012-2013 when the MST Hub comes out.
It looks like quad/tri-fire can't handle 3 30" either due to the crossfire bridge bottlenecking; only 6990s, albeit with no AA since they'll be slamming up against 2GB even without it. 3GB 580s are too expensive for my blood. :(

Yepp. 6950 with unlocked shaders. Also DVI-DP-DVI configuration, only occurs in my 3x1 group. Though for me, only the Center tears,it's pretty slight, and only really noticeable on video playback and webpage scrolling, but it's there. Oh, using mini-DP to DP cable. 11.3 drivers.
Oh. I get it in Extended, as well. But only center display. HAve the newer drivers fixed this?
