7970 Eyefinity Screen Tearing problem Still Exist?

Ah ya, now that I think about it you could limit the tearing to one screen by setting one of the side monitors as the "primary" display.

That's what I did. I'm running 2 monitors DVI and one off of mini-DP. I set the mini DP one on my left side (non-dominant eye side), and then in CCC set one of the DVI monitors to "primary." I barely notice the tearing since it only happens on the left-most monitor and my dominant eye doesn't focus on that one as much.

Sure you can. A few manufacturers have already done it with Eyefinity 6 versions of cards. Put all miniDP ports on the card, then include a few legacy adapter cables. Then you get the ability to connect up to 6 monitors and the flexibility to use whatever connector type you want.

yes, but not for reference design...those 6 port cards are niche designs..

don't forget eyefinity setups are in the minority, most people just have one or two monitors. They dont want to hassle with resignaling cables...

Who can forget the rats-nest of dongles that was the ATI AIW 9700pro?

lol

Those DP ports require passive/active adapters adding to the cost of ownership, weather they ship with the card or not.

Reference design is supposed to appeal to the most people possible therefore there will always be 2 legacy ports on refernce designs otherwise like isaid, you are wasting a RAMDAC (or two if you have no legacy ports).....

i suppose the cost could be somewhat mitigated by a redesign dropping the two legacy RAMDACS, but thats cost money too...

Just make the reference design the Eyefinity 6 version.

And it doesn't "waste" the RAMDACS by going all miniDP. You can still connect two monitors on those cards with passive adapters (which are what's typically included with those cards). It wouldn't cost that much more to include a few passive adapters (especially considering they already include a couple of adapter cables with the 7970...probably one miniDP to DP and one HDMI to DVI, at least).

its not quite that simple, there is board redesign involved for switching logic nessisary for use when the passive/resignaling adapers are being used for the legacy RAMDACs instead of the direct DP.

So, again, you wont see them on reference designs...

Perhpas if ATI included that logic in its refernce design, it could be up to the board maker to determine how they want to wire the ports...

That would however increse the cost of the card, not something ATI wants to do at launch particularily when a large majoriy of the market is still using legacy monitors...

Question: Is there still Eyefinity Screen Tearing with 7970 using different output connectors

Answer: Yes there is, it is there, and noticeable. No change.

Using DVI + Mini-DP + Mini-DP = There is tearing on the display with DVI. The Mini-DP displays = no tearing.

Well this puts a damn kink in my plans...
 
Note this is with the AMD supplied driver for use with 7970. I have not tried Catalyst 12.1 Preview or 12.1a preview driver yet.
 
How is eyefinity set up if you are xfiring. Are all 3 connections off one card or can you use a combination of connectors from either card?
 
I was afraid of this. This may mean Kepler for me but since I'm experiencing this already, then if Kepler isn't coming as soon as I think it is, then the way I look at it is:

More performance with the same issue is better than the same issue and my current performance. I might get 7970 or 7950s if they unlock if kepler is still months out and then switch to kepler. This issue and display port blanking out my screens randomly have me about to throw in the towel with AMD Radeon cards until they get their shit together.

BTW this does happen in gams but only if movement is fast enough. In Batman arkham city, for example, if you grapel up a tall building and acellerate with the mod it will speed you up enough to cause a tear in game. Several other games exibit the issue under the correct circumstances.

Thanks for looking into this Brent!! You are the Man! :)

BTW drivers will not fix this, it's a hardware issue, I'm convinced of this.
 
I'll be doing some more testing in another game this weekend, after I finish this OC article, and Ill install the latest 1.21a driver and report back using that driver, just in case.

Also note, I am NOT seeing this issue in GAMES, only in Windows.

hmm this is interesting: hope that 12.1 or 12.1a fixes this. Tearing in windows is a deal breaker for me.

Weird,

I would notice this problem in windows AND games. So maybe there is a fix implemented or something?
 
I have this problem too with my 6950 and its very annoying. So annoying that I barely use eyefinity mode anymore... If i'm not in eyefinity mode in windows, then there is no tearing at all. But with eyefinity on, its noticeable in both games and windows.

I was hoping this problem would be fixed, but this may hinder my upgrade...

A little of topic, but does this happen in nvidia surround?

No tearing for me in surround. Neither in windows nor games.

WOW it still does this?!?!?! fucking....wow AMD seriously.

Only way to fix this is to run all display port monitors....with a card that has 3 display ports on it.

Fail AMD (although i gave up on using my eyefinity setup until bezels are gone)

This issue only happens when you mix/match different outputs.

so 3xdvi would not have an issue, nor would 3xdisplay port.

Which, it should be noted, is impossible on the reference 7970 design. Asinine!

Exactly. Thats why whent he 6970's were released, the best card to get was the Asus ones since they had 3x displayports.
 
Customized cards from AIBs might have different output connections.

Custom cards are just gettin started, I'd look for some flexibility to come in the future.
 
Was the tearing issue strictly a 6900 series issue? I had the problem on my HD5850 with the shift in a window when moving it from one screen to another but that was solved with drivers over a year ago. I have tried moving the window really fast on the screen connected to the dp port and don't get the tearing like in that vimeo video. I have my screens in portrait while my daughters are in landscape mode and I have tried it on both setups. I am not trying to start any fights just trying to learn more about the problem.

Nope, its an eyefinity tech problem.

If all 3 monitors arent using the same port, it can cause the tearing effect.

The reason Nvidia does not see this issue, is because they use 3xdvi.
 
Just get the 6GB 7970's with 6 mini-DP. That is what I am waiting for.

A lot of people myself included had no tearing with mixed output with their 5 series card only to upgrade and get the tearing with the 6 series.

I was thinking about picking up a 7950 to replace my gtx 460 2gb surround but that plan is now shot. Bravo Amd...
 
My tentative plan is to try out a reference 7970 at launch. If I notice tearing then I'll be sure to Crossfire it with a non-reference card that has 3xDP (or move to Kepler if I can't support 3D Eyefinity with projectors using AMD).

Same - well, sans the whole 3D stuff. So mostly the same. Mmhmmmm.
 
The 7990's should have 4x DP just like the 6990's, just have to wait until March.
 
you DON'T NEED an active display port adapter. I use a passive one for 1920x1200. Only if you are going higher then that will you need an active adapter.

you need it if you are going to use more than one DP, or dual link....
 
Also you will need one if you run a 1080P 120Hz screen. Passive adapters only work at 60Hz.
 
This is interesting.

I have two 6970's. My two side monitors are hooked up using DVI. My center monitor is hooked up using DP.

I have never noticed the tearing.

Maybe it's there and I just haven't been observant.
 
^ I'm not 100% sure on that device, but things like that usually only clone the display, i.e. making the same display visible on two displays
