[quote]The configuration is still limited by the number of clocks on the card. The 6850 and 6870 will only support six monitors, regardless of the number of adapters or hubs you have.

Well if I read correctly, that seems incorrect.
For DP, there seems to be ONE clock for all the ports. Then there are two clock clock for DVI / HDMI / VGA (DVI->VGA adapter).

So bandwidth allowing I see 6 on DP, and 2 on "legacy" ports = 8 monitors.

I also head that those HUBs will have built in clocks for each port. Which makes sense, because then DP 1.0 / 1.1 wouldn't work with the HUBs.

Some ports share clocks. This is the reason you can't do DVI+DVI+HDMI. All I can say is that I asked AMD specifically, and the reference 6850 and 6870 can only do six displays.

Do we know if there is going to be a 'specialist' multi-monitor card ala equivalent of the Eyefinity 6?

I.e. is there going to be a card with all mini-DP outputs allowing at least a straight 1:1 connection of six DP monitors (presumably with DP1.2 support for daisy chaining options etc.) or is the dual 1.2 DP, dual DVI, single HDMI going to be standard across the board (i.e. max of 5 monitors without using DP1.2 capable monitors or hubs).

I asked this question on the conference call announcing the 6850 and 6870. The answer from Dave Baumann was, "We'll be having those discussions with the 6900 launch."

It was this one....

I ordered a 6870 and will report how it will behave with the Bizlink DP > VGA *crossesfingers*

Any dates on the 6900 launch?

Any dates on the 6900 launch?

The original embargo date was late November, but has been pushed into mid-December. Here is some other info that recently leaked out:

Looks like 6990 will be early January...

I finally got my PowerColor 6870 and had no troubles to get 3 monitors to work at once and forming an eyefinity group with miniDP>DP and Bizlink DP>VGA adapters. After configuring Bezel Compensation it resets to one screen though. it seems to save the bezel compensated resolution and its selectable ingame, but it doesn't really look bezel compensated :-/ had little time to fiddle around with it though, will try later.

I found my problem to be with the Gigabyte video card, itself! One of the Mini-DP ports was bad and the other was "iffy" at best.

I sent that card back to Newegg, they refunded my money, and I picked up an XFX HD6870 this morning. Within 30 minutes I had a 3x1 Eyefinity group enabled and it's been close to an hour now without the first hiccup.

Yay for XFX!!!

Good review!

For the setup, a reference 6870 was connected to 3 x Dell U2211H (which has a DVI, a DP and a VGA input)
May I ask which 3 outputs of the 6870 were used to connect to the U2211H (and what inputs were used respectively)?

Thank you.

I have 3 matching dp monitors. Sold my 5970 2 weeks ago. Using 2x260gtx in multimonitor till the 6990 comes out or I go 580 or 570 sli.
Since I used eyefinity for 11 months and nvidia surround for the last 3 weeks I was surprised to see that I liked the eyefinity solution better.

When I had the 5970 I also used a 250gts for physx. For a fourth monitor I used a tritton usb to vga converter. Worked very well with the amd card but it does not work right with the nvidia solution. When I use the tritton it disables physx from the nvidia control panel and even gpu-z says physx is not working. If I disable the tritton uv-150 the physx comes right back.

CAN the 6870 use 3 monitors in triplewide gaming and use a fourth monitor for extended display? I like to have pc temps, voicechat progs open while gaming. Remember I have 3 native dp monitors.

Sorry for the delay. I used 2xMini-DP and 1xDVI. For the Mini-DP, I use Mini-DP > DP cables.

Yes. The reference 6870/6850 supports four monitors. I don't see any reason you couldn't use your USB monitor if you wanted.
