[Reaper114]

Thanks, I'll have my HD 5770 soon, and I wanted to know if you were using the same setup. Hopefully I can get similar results. Fingers crossed :)

Well i got my Dp to VGA adapter yesterday and was very exicited...Plugged everything in but no luck. DP screen does not come on...Fiddle around and the got it running @ 3840 x 1024 , which looks bad as my screen are 1920 x 1080. All of them Benq T2200HD's.
Played more but no luck and then BANG: BSOD with them message: atikmdag.sys
From then on i could not activate my DP display. each time i do it BSOD.
This morning decided to format and re-install Windows 7 with the hotfix dirt2 driver...reboot...nothing dp display off. ....click on detect display...bang eyefinity @ 5760 1080, but my dp display flinkers on and off every few second...reboot...start up...no eyefinity...try setting it up..bang BSOD...well at work now...this not good.

[quote]I tried the dp to vga from apple, it doesnt seem to support 1920x1200,when i make a group it forces all three monitors to do 1600x1200???

which native resolution do your monitors have?
does it work with a single screen in 1920x1200?

in the german apple shop, some1 commented it does work with his 1920x1200, but most specs around the net only mention 1080p

Native res. is 1920x1200, i tried hooking up 1 monitor,via dp>vga, and the highest res was 1600x1200.Will try active adapter later this week, when it arrives.

I have purchased one of these from the UK seller linked in this thread, got the item 2 days after payment so thats the good news out of the way.

bad news if just like the active DP adaptors the monitor connected to the DP blinks black randomly.

Hi, I'm new to multi-monitor gaming, but have 3x 24" monitors running @5760x1200 with my HD5870. I did now know that such a simple adapter would work, instead, I spent a lot of time and effort scouting around for an active DP->DVI adapter. It's non-existent in my neck of the wood, so I had to resort to Amazon, ordered it and wait for stock to be replenished. Finally got it a few days back, it's an Accell B087B-002B btw, and it works right out of the box. Followed [H] video review on how to enable EyeFinity and I've been cruising along since. Anyway, I'll be around here more often asking questions when I need to, so please excuse my 'newbishness'. :oops:

Thanks! :cheers One question though, when IS ATi gonna release a driver that supports CFX + CFX for users like me? I'm not the only one you know.... :wink:

Thanks to TexasTango for the info on that time. I saw it while poking around monoprice.com and they have the damned thing for a measly $23.44 shipped to Canada. Saw the mention of the "chip" and figured it'd be a possible TH solution. And lo, WSGF has info on it, already. Lovely.

But now I'm considering buying 3 24" displays instead of a big TV, but my local stores only have shitty TN panel displays and I'm too paranoid to order something so pricey without eyeballing it first, Sometimes living on an island is a p.i.t.a.

GUYS!!! And Gals :D I am happy to report that I received my $20 Monoprice DP->VGA Adapter. And it works! At FULL 1920x1200 RESOLUTION! I was really worried after reading reports of high resolutions not working properly with these adapters, but this one works almost perfectly for me! I say almost, because I do get the flicker issue that many people have reported - but the same issue has been reported on the expensive DP->DVI adapters as well. By flicker, i mean that once every once in a while (seems like every 15 min or so) the screen will flicker black for a moment, as if its lost signal, and then return to use. Games do NOT lag when this happens, so I'm not too concerned about it - hopefully ATI will fix this issue in a future driver release.

Here's the adapter i purchased:

And some screenshots of the final setup! Those are 3x Dell 2405FPWs, attached to a Radeon 5850.

Welcome, Nice setup and have great fun. Well you are lucky to only get flicker every 15 minutes. Mine starts of by flickering often and then after a few hours it gets less to a point where i don't have any. Don't know the reason for this.

[mikeysg]

Well, with the active DP->DVI adapter that I have, I don't have this flickering issue. Only odd issue (sort of) is that when I power up my system, one of monitor stays in standby mode, I'd have to hit the power button to switch it off, then I switch it on again and it's fine. I'll post a pic or two of my setup when I've finally align the monitor perfectly, still a little off right now....looking around for a 3x 24" WS monitor stand, only model available now fits 3x 19" WS LCD's.

[Abram]

Sweet to hear it does actually work. Good thing they have cheap HDMI and dvi cables, too. Now i can triple-display with my three not-all-all matching displays.

[chineseleper]

I can confirm that Eyefinity is working with the HP DisplayPort To VGA Adapter (AS615AA) at 3x 1680x1050 without any problems at all. I just got one in Germany for 11€ incl. shipping.

[Shooter777]

So you having no flickering on and off of your dp screen

Have you written a Monoprice review yet?

Guys I joined this forum to respond to this thread. I have ordered the adapter mentioned and it did not work with resolutions above 1280x768. Anything higher and the screen would show scan lines, sort of like what happens when you are trying to tune in an old tv that is getting signal via antenna.

I tried 3 differently shielded cables, 2 5870's, 3 20.5" Samsung monitors capable of 1680x1050, and I went out and specifically purchased 3 Acer 23" monitors capable of 1920x1080.

I'm very upset with this whole Eyefinity setup. The best I can do is with the Apple adapter. The Dell adapter is horrid and only works for a few min at a time. The Apple will not work with 1680x1050 for me so that is one reason I bought new monitors. The Apple adapter at least works rock solid @ 1920x1080 but has problems recovering from a resolution change when I create the display group. I have to unplug the usb and plug it back in for the adapter to recalibrate itself, otherwise I'm stuck at 640x480.

I wish ATI would pull their heads out of their rears and either get an adapter out for us that works or make a card with a different connector on it.

Just curious-
What power supply are you running?
Single 12 volt rail, or multiple?
Amps per rail, and total amps?


I run single rail, 60 amps and have none of the problems you mention with either DP-VGA, or Dell DP-DVI adapters pushing 3840x1024 on 19"-22"-19".

Thanks

4 12+ Rails @ 30A each

I put each card on a separate rail. I've had the USB plug of both Adapters plugged into the motherboard, a separately powered USB hub, and into an AC adapter. I do not have the cards overclocked. Everything on the system works flawlessly except for Eyefinity. I've been reading elsewhere about a bios update that ups the driving signal to the displayport. I may try this when I get home tonight to see if it solves my problems.

I can confirm that the DP to vga adapter from monoprice works with three 21" monitors running at 1600x1200 resolution. Here is a post of the setup that I made on another forum.
