So I just purchased a second 5770 and am now running both cards. I've noticed that I can't run my three screens when crossfire is enabled. I've also noticed that I can't merge all three screens into one giant resolution in CCC. How can I accomplish this?
If you don't have it already, you'll need the latest drivers. They added Crossfire support in a hotfix for 9.2 but it is also found in 10.2
Turns out you can't run three DVI monitors spread over both the cards. How gay is that? You have to spend shit-tons of money on displyport just to run three or more screens? That's really annoying.

Isn't an active displayport to dvi adapter like $100?
[QUOTE=thf;20448726]Isn't an active displayport to dvi adapter like $100?[/QUOTE] yes it is
[QUOTE=Daolpu;20447817]Nope, those two (assuming he bought the HIS ones from Newegg) cards combined are only $304.00 as opposed to the $300.00 for the adapter. It's an entire four dollars. :smug:[/QUOTE] What? That doesn't make any sense. I use the $300 I spent to purchase TripleHead2Go... but then I have no graphics card to hook it up to. Also, running three screens as one resolution on a single 5770 is going to rape my fps ingame. I just gotta save up another $100 for an active adapter so I can run crossfire with eyefinity.
Doesn't triplehead also have vertical resolution limited to 1050 or 1024
New drivers (out next month) will allow eyefinity on crossfire setups.
[QUOTE=thf;20448726]Isn't an active displayport to dvi adapter like $100?[/QUOTE] If i got one of those, could i use 3 monitors on one card?
[QUOTE=birkett;20455606]New drivers (out next month) will allow eyefinity on crossfire setups.[/QUOTE] As in it'll allow three DVI monitors (two monitor connected to card#1, one monitor connected to card#2) to run eyefinity? If so... I don't even know... I'll be so happy. [QUOTE=Shadowspike;20455759]If i got one of those, could i use 3 monitors on one card?[/QUOTE] Yes. Three DVI monitors would work on a single card if one of them was using an active adapter.
Here is the info you need... [B]1. Regardless of whether or not you run crossfire, you can only use the ports on the primary display adapter in Eyefinity.[/B] They have stated elsewhere that you will not be able to use the ports on a secondary GPU in an Eyefinity setup; this is due to the fact that there would be syncing issues. Just like the tearing effect that can occur without Vsync on, whole display panels could be out of sync with the others. It isn't an issue that can be fixed through a driver update. [B]2. You must use either: a native displayport monitor, OR a passive DP to VGA adapter, OR an active DP to DVI adapter in order to use a third monitor with Eyefinity[/B]. This is due to the fact that the GPUs only have two timing clocks and each DVI output requires one, DP does not so you can use that, but if you are using a DP to DVI you need an active adapter to generate a timing clock. Currently they can't be found for less than $100 and some people are experiencing strange and often annoying behavior when using them. [B]3. Eyefinity has supported Crossfire since the 9.12 hotfix. It is also present in current drivers.[/B] As stated earlier, no driver release is going to add the ability to use ports on secondary GPUs. [B]4. Triple Head 2 GO has been around for many years but has significant limitations.[/B] The maximum resolution per monitor is 1680x1050 and if you choose to use their bezel management software, some of those pixels will be shifted out of view and you will be left with black bars on the edges of the two outer monitors. It is also quite a "hacky" solution and often involves editing config files manually. It's $300 price tag makes no sense with the advent of Eyefinity. Eyefinity can support resolutions in excess of 2560x1600 per monitor, requires no additional hardware (unless you need the active adapter), features bezel management (a feature of 10.3 drivers I believe) that adds pixels to the edge of the screen, and allows you to use them as regular extended desktops with ease. They are working with developers to get it working with a multitude of new games coming out. I have purchased 3 Dell displayport monitors in anticipation of my own Eyefinity setup...just have to wait a few weeks longer to get the GPU. I've done plenty of research on Eyefinity so if you have any other questions, I'd be glad to help.
How can you run 3 displayport monitors off one card when theres only one dp port?
[QUOTE=thf;20458230]How can you run 3 displayport monitors off one card when theres only one dp port?[/QUOTE] Displayport to DVI dongles. ATI should be coming out with "eyefinity" versions of the 5000 series, which includes 6 displayport connections on each card.
[QUOTE=thf;20458230]How can you run 3 displayport monitors off one card when theres only one dp port?[/QUOTE] The monitors have DP, VGA, and DVI connections. I'm going to be using 2 DVI ports and the DP port. [url]http://accessories.us.dell.com/sna/products/Displays/productdetail.aspx?c=us&l=en&cs=19&sku=320-8325[/url] Their will be a 6 mini-DP 5870 available within a few months. It will have to DP+ ports that will allow you to run 2 DVI monitors with passive adapters, and the other 4 ports will require you to use an active adapter if you wish to use DVI connections. It has been hinted at by the product manager for the 5700 and 5800 series that this card will come with some adapters, at least likely to have mini-DP to DP adapters. The official name of the card is the "5870 Eyefinity6 edition".

[QUOTE=MTMod;20459742]Holy shit. $750 on monitors alone? That's crazy.[/QUOTE] There was a sale on when I bought them. I believe they were $210 each + tax and shipping. Prior to that they were on sale for $189. Sadly I missed that deal. They are really awesome monitors though. They came with DVI, VGA, and USB cables. It has an integrated USB hub. It also has a 3 year premium guarantee. No dead/bright pixel policy too. Much better than my original Sceptre monitor. Can't wait till I can use all three. Stuck with a GTX 260 right now. :dance:

They are not using Eyefinity for that. There was another demo they did awhile back where they had a flight simulator running on 24 screens. Apparently you can run mulitple instances of FS and have them sync up. Apparently there was still an issue where one or two monitors would lag behind the others.

[editline]08:16PM[/editline] Because I may be buying one of those monitors. [editline]08:17PM[/editline] And can you not run one monitor from HDMI, two from DVI and one from DP?

[editline]08:17PM[/editline] And can you not run one monitor from HDMI, two from DVI and one from DP?[/QUOTE] I find the monitors to be incredible, but it really is a matter of perspective. There are snobs in a [url=http://www.hardforum.com/forumdisplay.php?f=78]certain forum[/url] that think TN panels are awful and that you should spend $400+ per monitor to get IPS panels. I personally find that ridiculous. If you use a HDMI port it will use one of the timing clocks so you have to give up a DVI port. For Eyefinity, DVI-DVI-DP is the only way. As mentioned earlier, you can use a passive DP-VGA adapter or an active DP-DVI adapter to use three DVI monitors. Of course, if you get one of these monitors which has a DP then no adapters are needed...something to keep in mind considering that the DVI adapter is $100 and can be temperamental. [editline]10:00PM[/editline] I should point out that you [B]can[/B] use more than 3 monitors with 2 GPUs, just not all grouped together into one Eyefinity group. So, as an example, you could have 1 5870 running 3 displays in an Eyefinity group and then another (not in crossfire) ATI GPU running 1 or more extra displays.

Unfortunately it doesn't look like you can buy them...[/QUOTE] [H]ardOCP ran an editorial on Eyefinity performance and if I recall correctly they said a single 5870 or 5970 can deal quite well with resolutions up to 1920x1200. Of course, that depends on what games you are playing; Crysis will require lowering most settings to a medium level, but I believe you can max source games like L4D2 even with some AA. The main issue with Crossfire and Eyefinity right now is that you become memory limited. That means even with dual 5870's or 5970's you will hit a ceiling in terms of what amount of AA you can use. The Eyefinity6 edition is rumored to have 2GB of memory and there is always the possibility of future custom OEM boards. Wow, a DP-only monitor. First I've seen. Does it match the resolution of your current monitors?
[QUOTE=ChristopherB;20468881] Wow, a DP-only monitor. First I've seen. Does it match the resolution of your current monitors?[/QUOTE] Indeed it does. Unfortunately this thing is like impossible to get. I even... *shudder*... called Dell's customer service. Also, I was speaking in terms of my situation. Three screens on a single 5770 is bad news. Oh how I wish I could crossfire 5870s...
Did you call them over the phone? I've used their live help chat feature on the website and it has been really useful. I have to say "ouch" at the 5770. No doubt it will be quite a struggle. At least the low resolution will work in your favor. I found it for sale on ebay, seems a bit pricey though.

Live chat isn't open on sat. and sun. Also, I live in the US, and I've already messaged that seller on where I might be able to get one of those monitors. Although I've suddenly made some cash so I might just purchase an adapter.
