When will the 7970 eyefinity cards be released?

[bamaaviator]

I have a 7970 that I cant stand. Did not realize that having different ports on the back of the card would effect performance, but I have horrible screen tearing on 2 out of 3 of my monitors.

My old 5870 did not have this problem. I contacted MSI and was told that there was really nothing that could be done about the screen tearing issue since there is no way to connect 3 monitors to these cards via the same cable. Every 7970 I have seen so far only has 1 HDMI , 1 DVI, and 2 Mini ports.....when are the cards going to be released that have 3 of ANY identical port?

Very, very disappointed in this card right now.

I don't know bud, but I do know the 680 can run 3 screens off one card and doesn't suffer from screen tears.

Seems odd, I'm running my Eyefinity on a 6950 with 2x DVI and 1x DP with an active dvi adapter and had no issues. What cable/adapter setup are you using?

I don't understand how the performance would depend on the type of port?

Are you sure the issue is caused by the type of port?

Just to play devil's advocate, I think the 5XXX series and 6XXX series cards can successfully use different ports without the issue you mentioned, so why does this not affect those cards using different ports, but does affect your card using different ports?

Can't you link 3 monitors with 1 displayport ? I was under the impression that you can hook multiple monitors up via 1 displayport with the proper adapters, thats one of the selling points of DP. I haven't tried it though, I've never messed with eyefinity.

 

[chimaxi83]

Each mini DP connector on 7970 can daisy chain up to 3 monitors each.

 

[dac7nco]

Unfortunately to those two posters above, those MST (SP?) hubs are not available yet. I remember Anand discussing that very tech when the 5870 hit. It seems like people like NEC and HP would include daisy-chaining tech in their upper-echelon monitors, but nope. Indeed, full-sided DP connectors should go away entirely.

Did you ever set the 2 common outputs as the main display like we mentioned before? That should limit screen tearing to 1 screen. Otherwise you need to get the Asus Direct II linked above or the Msi Lightning and the apropriate adapter(s) to get rid of the screen tearing. Or as someone else mentioned just get a gtx 680 = no screen tearing.

Nope 5xxx and 6xxx had the same issues though it got worse with the 6xxx series(more people experienced it). Not eveyone gets it but many do. I believe it has something to do with the monitors being used.

i haven't had the screen tear with the last couple driver iterations.

i thought nvidia cards could only run 3 displays while gaming?

Thread winner. Had this card for a bit, no tearing across three u2311h via display port.

I like AMD and have had ATI card's for a long time. With that said, my friend and I were both really frustrated with the screen tearing that came with the 6000+ series. We spent hours researching to try and resolve the issue with no luck short of buying new cards. Now, seeing the same issue carry over into the 7000+ series is kind of sad.

Not only that, but the fact that AMD is completely silent on the issue and refuses to address it or provide a solution is kind of pathetic. Their documentation on Eyefinity that I have seen gives no warning about the tearing nor have I seen any official response on potential corrections in the hardware design.

Now that Nvidia has gotten off their lazy butts and done 3 monitor support, my friend has already swapped to a 680 and is getting no screen tearing right out of the box. I will be following him shortly as soon as I sell off my X-fire 6970's to get a 680.

In my opinion, both camps have really dropped the ball on multi-monitor support. I realize there may not be a large market segment using this, but if you are going to promote something as a company to increase sales, then you should make sure it works properly.

I have a single 7970 running 3x30" monitors at 7680x1600 with no issues.

I am required to have an active display port adapter, which is a bit crap, but everything works very well.

 

[AravanLandorin]

Which 7970 and you say you are getting no screen tearing in gaming at those resolutions?

If it's just normal use pc use, I never got screen tearing. The only time I ever had issues was in gaming at 5760X1200. The best I could do was get it to where only 1 screen would tear. I am also using active DP adapter for the 3rd monitor.

This is the same info that I found on tons of different websites and forums. The best you can do without a custom eyefinity card is tearing on 1 monitor while gaming.

I can't even imagine using a single 7970 for eyefinity when even 7970 cf barely cuts it for heavy games

All AMD 3 monitor DVI users have the tearing problem, they might just not realise it. Most users have 2 real DVI monitors and one attached with an active DP->DVI adapter and its that DP screen which will tear. Its actually pretty rubbish and I was quite annoyed that they decided to carry the problem across to the 7970 because they could have added another clock source or made it entirely DP with adapters for the extortionate cost of the card.

Personally its one of the few IQ things that don't irritate me with the AMD cards. I don't see it all too frequently and the tearing isn't that severe, for me at least. But I acknowledge the problem and anyone who says they don't have it either is running all DP monitors or else doesn't notice it, but its there on every card (except one particular model which was released with 3 clock sources by Sapphirein the 6000 range of cards IIRC).

Honestly NVidia with the 680 GTX has zoomed passed AMD with its surround support. With true 4 monitor support without tearing and better performance its really just a matter of availability. I can't recommend the 7970's, I've had lag problems in Windows, I have crashing bugs in CF and poor performance in all sorts of circumstances. It's a lemon of a card for its price, in many ways its a massive step back from my 5970 and that was far from stable.

After using 2x 7970's for 3.5 months I would recommend getting a 680 GTX. I haven't used one so I can't tell you what actual problems it has but I can say for certain the 7970 has problems which if you have them there is no known fix for and AMD support as usual is rubbish. Had I waited and I was offered these two choices today I would wait for the 680 GTX to be available. I hate these 7970's, they were a terrible buy and my next card will most likely be NVidia as long as it keeps up performance wise.

I disagree - I have tried a Sapphire 5870 and my current MSI 5850, no screen tearing that I can notice, and I can be picky.

I've seen a video of someone showing the 'eyefinity' screen tearing but I could not duplicate that result on my system. Do you have an example of the type of tearing you are talking about? It's not like the Vsync tearing right, but more of a mismatch on a border of a window when you move it across the screens, from one monitor to the next? Or what are you saying is present on every AMD card that I cannot detect on two AMD cards?

Interesting.. perhaps making a thread about it on AMD forums would be fine in that the thread won't get locked, but if not, then I guess you have to submit for a support "ticket".

It manifests to differing degrees depending on the active adapter and the monitor. But it ranges from a mild misalignment of a Windows borders across the horizontal plane when moving the Window quickly all the way up to 50+ pixel breaks across two screens.

I find decreasing the clock speed of the card increases the effect, and subsequently increasing the clock speed reduces it. I have no idea why that is, makes no sense to me but it can help reduce the problem.

Another way you can sometimes see it is to playback video across each of the monitors and you'll find one of them has a tendency to stutter and tear. But with tears of 1 px a few times a second they can be hard to spot, and recording them in Fraps etc doesn't seem to work.

Some people are lucky that its minor (you and me) others as you have seen have it much worse.

Im using the MSI Lightining model 7970 and running 3x Asus 27 inch monitors...all of which are displayport enabled. I have an active displayport adaptor and it still doesnt fix the issue.

I had never read about this problem before I purchased the card and never had any issue with the 5870.

I saw the model posted above that has 3x identical ports, but it seems to have a very high failure rate according to the egg rating on newegg. Could just be people trolling, but 31 reviews and a lot of them negative doesnt do much for my confidence level in buying that product.

The screen tearing I get is down right horrible in games, and I am no videophile. If I am gaming on the center monitor and browesing on another, it isnt much of an issue. However, load a game in 5760x1080 and its so annoying the games arent playable.

I may sell this model and move to Nvidias 680s this round if this isnt fixed in the very near future.

They can't fix it, its a hardware limitation. 680's are native DVI so you wont have this problem on NVidia at all.
