i currently have the 5850, with three monitor baring 1080 resolution, from what i read so far only the 100 dollar ones with the usb works without a hinch? since the dp-vga only works if you have a higher resolution and a lower one?

Yeah I think it'll work with 1920 and lower.. or maybe just 1680 and lower. I'm not too sure. Either way I don't have panels that scale greater than 1680 so I hope I'm in the green!

I have three 22" at 1920x1080 and my DP-VGA works fine. This only after i flashed my BIOS.

Had my Monoprice VGA adapter for 2 days and here's how it's working for me:
When I turn the computer on all 3 monitors come on, center one primary, one on the left and the one on the right are extended desktops. They work as expected.

If I turn Eyefinity mode on the Displayport one will go black. I have to unplug the Displayport, and plug it back in, then fiddle with Catalyst (opening and closing it) before it will go into Eyefinity mode. Once in Eyefinity mode it seems to work fine. Anybody else think that might just be a driver issue?

On games I got it to work with several on its own, at first Widescreen Fixer didn't want to do anything with Call of Duty, but I eventually got it to. Crysis is the only one that refuses to load with an Eyefinity resolution. (While loading the center area and a bit of the side monitors remains black, but where they never expected anybody to see on the edges turns white, then when it gets to 99% loaded the sound goes into a stutter and it locks up.)

edit: I wanted it to be a reply in this thread: http://www.widescreengamingforum.com/forum/viewtopic.php?f=64&t=17468 but I don't know what I'm doing wrong. I could swear I hit reply, but it created a new thread twice. [merged ;) - /mod]

I think it's a combination of drivers and a hardware issue. From what I've read, the BIOS update for the 5800 series cards made some changes to the Display Port which appears to have resolved the issue for those cards. I've got a couple of 5770's so I'm waiting to see what will happen there.

As far as software goes, yes I believe it contributes to the problem. I received the same adapter yesterday and I've had the same problems. It was working fine at first, all 3 monitors appeared and were working fine under Windows. Then I tried to enable Eyefinity and all hell broke loose to the point where my monitor with the adapter is blank in Windows (appears fine when booting). I've tried numerous things (different cables, replugging in and out, playing with the software etc) and it just will not renable, complaining of a Display link failure.

Hopefully a BIOS update will arrive for the 5770 series and I'll give it another go then.

What monitors and resolution are you running?

I've got 2x20" Dell 2007's @ 1600x1200 for my left and right screens (left has the DP>VGA), and a 24" Dell 2405 @ 1920x1200 for my centre screen. Of course with Eyefinity they will all run at 1600x1200 for a total of 4800x1200.

I did a bit more fiddling around, this time I was able to get all 3 displays running in Eyefinity on the desktop after unplugging/plugging the DP>VGA a few times. But as soon as I tried loading Dirt 2, all screens went black and my PC locked up.

At the moment I've got all 3 displays going with the normal desktop extend. I'll see if this lasts without dropping out, but for now Eyefinity is still out of reach. :(

Is does seem like using different monitors can cause problems sometimes. I'm waiting on my DP>VGA adapter to arrive and I also have 5770s in crossfire, but I have three identical 22" monitors. I'll post here how it goes.

Here's what I do, I boot up with the DP>VGA adapter attached, it shows the extended desktop with 1 primary 2 extended, Displayport one working fine. I go into Catalyst, set each one of the 3 to Duplicate instead of extend. At this point the DP connected one goes black. Unplug, and plug that one back in. Close Catalyst, Open Catalyst again, now set that one to Duplicate. That time it'll stick and you will have the same image on all 3 screens. Then click the down arrow on one and enable the Eyefinity mode.

Awesome stuff it actually worked! However for some reason I still couldn't get Dirt 2 to work. This time it loaded fine and I had the resolution 4800x1200 in the settings, but when I selected it, all screens went black and some weird white lines started appearing on the main screen which went away as soon as I unplugged the DP>VGA adapter. However I was able to get Badlands to work so I've finally got some sort of Eyefinity setup working! Still a work in progress. :wink:

Thanks ualdayan. :cheers

I have a VGA>DP adapter from here http://www.dealextreme.com/details.dx/sku.20776

After some initial issues on getting Win7 to get the monitor on the DP to run in it's native 1920x1080 resolution I have it going no problems.

I don't suffer from any of the black screen flicker that some have. But, switching between Eyefinity and Extended is a nightmare with the monitor on the DP port. It will always loose the DP connection and it takes several unplugs/replugs/Catalyst restarts to get it back. Then I need to reconfigure the monitors as they are always in the wrong order. The profiles don't seem to work, as selecting one of them doesn't bring back the settings. Although, loosing the DP link may have something to do with this?

I haven't done a heap of testing yet, but it appears booting up is an issue as well. I've done 3-4 restarts and everytime I've had to unplug/plug the DP monitor several times to get it to display. Does anyone have their POST screen display on the DP>VGA monitor as their computer boots up?

re-reading the posts in this thread, I made the monitor connected to the DP port the default monitor and that seems to have gotten rid of the DP link failures. Except from boot up/restart, where the DP Link doesn't work until I unplug>replug the DP.

I spoke too soon re the DP link Failures :(

At first I was thinking that this a totally hardware related issue. Then today my DP>VGA monitor fired up on boot and showed the POST screen. Interestingly, one of the Other DVI connected monitors didn't come on while this happened. Once the Win7 logon screen came up the DP>VGA monitor went off the DVI one came on and I had to do the plug toggle to get all three on.

Playing with the CCC profiles is still problematic, with the changes doing random things when switching between Extended and Eyefinity. Most times switching between the two causes the DP Link failure - not always. I even had the monitor recover from a DP Link failure once today but using the profile hotkeys without needing the plug toggle. I couldn't replicate this tho.

The profile switch in CCC sometimes seems to die. When this happens, using the hotkeys or selecting the profile from the menu does nothing. The CCC app seems to blink but does not switch to the profile. CCC still seems to working ok as I can do do other stuff within the app, it just will not switch the profile. Restarting the runtime is the only solution I have found to fix it.

So, it does seem that the DP Link Failure could possibly fixed in the driver which should negate the need to fumble around at the back of the PC. Those DP plugs are not the easiest of things to unplug and plug.

Does anyone have their POST screen display on the DP>VGA monitor as their computer boots up?

Yes, the displayport screen and 1 DVI monitor show post text, and when it gets into windows the other DVI port becomes active.

I use this one http://www.newegg.com/Product/Product.aspx?Item=N82E16812270279&cm_re=dp_vga-_-12-270-279-_-Product

It's an updated version to ones we first saw. And cost about the same. I haven't had any issues with it since plugging it in for the first time. The only issue is a link failure if you let your monitors sleep. But I just turn my monitors off when I leave the room and set the power setting to never sleep.

Interestingly though I made contact with bizlink's engineers and they seem interested in troublshooting that device and why it constantly flickers. If I make progress with that I'll post it here.

But allasudden my main DVI output won't send a signal any more to my center monitor. But it will if I use a DVI-VGA adaptor like supplied with the card. So that sucks. I think the card may have to be RMA'd

This morning on boot up, all three monitors showed the post screen and windows login. I had the PC in Eyefinity mode when I shut down last night. When I got into windows the monitors were all duplicates and not Eyefinity. CCC was showing that I was in Eyefinity so it wouldn't fix it. I had to change back to Extended desktop, then back to Eyefinity before it worked (with the normal DP link failure happening in the process)

I can confirm the dp>vga works for me 100%

i have it set up at 5760x1200 on 3xdell 24inches

left monitor = DVI
middle = dvi>vga yes u read correct
right = (primary monitor) DP > vga

I have it working flawlessly without any flickers or whateva, windows keeps all settings after reset.

Been playing left4dead2 at 5760x1200 4aa 16af very high I get about 35-40fps average on my 2.4ghz q6600 with 2 gb ram lol!

very please with this $18 buck adapter :P

Took me about 6 hours to figure everything out though. You really need to play around with it.

wow i have the same issue, but mine is the 2nd dvi connection lol!

So I'm using dvi to vga atm which works 100% so I ain't complaining lol!

VGA vs DVI = no difference in PQ for me

Hi guys first post.
I have an acer 27IN 2048X1152 ,i have an older 24IN Dell 1920X1200.
I purchased a xfx 5870 ,a cheap hp 1900X1200 lcd (to match my Dell)
and I then realized i needed an adapter so i bought a passive dp to dvi adapter.

1)my first concern are my different monitors.I was hoping i could put all three at 1920X1080 res.will this work?
2)my second worry is my passive dp to dvi.Everyone says dp to vga is the one to get.I was wondering if i could stick one of my dvi to vga adapters that I have laying around on top of the dp to dvi adapter and effectively be the same as a dp to vga?

I already ordered to 5870 card,extra monitor and that bloody dp to dvi adapter so some advice would be greatly appreciated.

thanks guys, good forum by the way :)
