I just read this on the ATi website: Does that mean that if I have 2 cards in crossfire, and want 3 displays, I can only run them off ONE of my video cards? If so, that's the most stupid think I've ever heard.
I am, but I want 3 monitors - 2x 1200x1600 portrait - and one 2560x1600. I can't do that with a nvidia card, so I will have to go to the dark side
Maybe he wants to upgrade? OT: Seems that way yea, even though you could get 2 "groups" of displays( 1 group on each card)
You mean have one group of 2 on one card, and the third on a second? Seems odd that I have to take a performance hit to run multiple monitors. So eyefinity can only run on a single card? 4960x1600 will run crap on one card! This sucks.
You can run Eyefinity on a Crossfire setup... So long as all the monitors are fed from one card. Here's a review from Guru3d where they did 6 display setup with 1 5870 2GB Eyefinity 6 card (the one with 6 miniDP outputs)... They then added a second card (same as above) and ran benchmarks. http://www.guru3d.com/article/radeon-hd-5870-eyefinity6-review/8 And here's a link to a video where I guy manages to get Eyefinity 9 going (using softTH) http://www.youtube.com/watch?v=QiYDbdHB548
I see. So even if all screens are connected to one card, it still uses the other card too? THAT makes more sense. Thanks for the links.
Yep... the second card is there to boost performance, but I think both cards need to be the same model/speed for it to work properly. Here's a bit more Eyefinty pr0n http://www.youtube.com/watch?v=N6Vf8R_gOec&feature=related 4 x 5870 2GB Eyefinity 6 24 Displays ---> 6 Displays per card - No Xfire
I can't be doing with these 6, or even 24 screen set ups because the dead centre of the screen always contains a bezel. IMO it only works with 3 screens. It's impressive as a technical showcase, but in reality, playing games where there's a bezel right in the middle is awful. I think I may go for 2x 5870s 2x 20" in portrait and obviously, my 30" in the middle. I don't like wide screens at the side as the camera view becomes too distorted. When you have a 30" as your main screen, you don't need 2 more 30s as they are out of your field of view anyway. Someone one here posted up his set up not long ago that has the same - 2x 20" in portrait, and a single 30". It looked sweet!
Aaaaaargh!!! Eyefinity does not support portrait/landscape mixing!!! *******s! SoftTH doesn't support DX10 or 11, so can't use that either. I'll be damned if I'm buying 2 more 30" panels, and even if I wanted to, I don't have the room for them either. That's that plan scuppered.
Ok... no need to panic. Although P-L-P configuration is not natively supported; some people have succeeded in fooling their GPUs into allowing it.... Here's a link where the user got it to work... http://www.widescreengamingforum.com/forum/viewtopic.php?f=64&t=19007 And here's a video of the setup at work http://www.youtube.com/watch?v=-AEAhExuaaM From the thread with the workarround... that trick is game dependant and will only work on some games... And since XFire is not compatible, then performance will take a hit.
Kinda related, does one of the three screens have to be connected via display port? I heard somewhere that with three screens on one card you can't use two DVI's + HDMI, but need to use Display port + any combination of the rest.
Indeed ATI does not CURRENTLY support PLP, however this is a feature they are looking to add in a driver update (which update and when however is yet to be known). The workaround is essentially just running the game in windowed mode and having it sctretched across all windows, this is while the ATI configuration is in extended mode (ie 3 independent monitors). This can also already be achieved with nvidia cards using the same technique. Of cause windowed mode usually takes quite a hit on perfomance for most games. Correct, the 5xxx series cards have 2 clock generators so they can drive 2 outputs as dvi/hdmi/vga(using a dvi/hdmi to vga adaptor), however the 3rd to 6th (depending on the card) additional outputs are displayport, for which you will require an active adaptor to convert to vga/dvi/hdmi.
Nice links, thanks. Windowed mode really sucks in terms of a performance hit though , and apparently won't be using crossfire, so that's not something I'd be willing to spend hundreds of pounds for, as I'll be paying for a performance hit. Not much of an upgrade Yes, one has to be display port, but you can get display port to DVI adaptors no problem. Easy tiger! Or do you mean because she gets a free GTX295?
