Displayport-to-VGA Adapter = Successful 3 Monitor Eyefinity

[Marksest]

I bought this adapter and it worked perfectly on windows vista with my 5770 and 3 4:3 displays. After I wiped the hard drive and upgraded to windows 7 then I started getting displayport errors, they're really getting annoying. Its an error with windows 7 and the drivers, not the hardware.

I personally like to beat dead horses with dead horses so...

I bought the adapter from Monoprice:

I am running 1 Samsung 244T along with 2 HP LP2465's(Thanks a4mula for the tip) on either side at 5760x1200.

That being said I have had ZERO issues. I am running the adapter on my main monitor since it has a VGA port on it. I am quite sure that is a major reason why it works but if you have a similar setup. I highly recommend giving it a try.

I finally got my displayport-VGA adapter to work with mixed monitors and thought that I’d share my findings. I had been getting the “Displayport Link Failure” error message when I tried to add the second monitor. My primary is a 24” (1920x1200). I was having problems when I tried to add a 20” (1600x1200) or a 19” (1280x1024) as a second monitor using the displayport.

The trick: Lower the resolution of the primary monitor to a resolution that is compatible with the other monitor before attempting to add the second monitor. Catalyst seems to force a clone first, and automatically sets the resolution of the newly added monitor to the same resolution as the primary. The link error occurs if the newly added monitor is incompatible with that resolution.

Note1: The monitor on the displayport wasn’t even showing the post screens at boot up. Once I finally able to see it and configure in Catalyst, it began showing up at boot up.

Note2: I’m using XP. I’m not gaming or using Eyefinity.

any of you guys got it to work under the new 10.1 catalyst ?

mine does work perfect (the DP/VGA adaptor) but after installing the new drivers the displays went on black , got no image at all anymore , had to go back to old driver.

[xxBLIZZxx]

My monitor on the adapter went black at some point through the installation. It stayed that way till I restarted but came back with windows. Created my monitor group and I was back in business.

That was in Win 7 x64.

mine stayed black after restart .. i'm on win7 32bit

I just got my Displayport to VGA adaper.

FAIL.......

x3 22" off the 5870. (2253bw-DVI)(226bw-VGA)(2253-bw-DVI)

1. Profiles don't save, so I have to reset all the display properties and start from scratch each time.
2. It requires unplugging the display port to get it to pick up again.
3. Black screen flicker.... once every 10 seconds.... to..... once every 3min..... There seems to be no pattern to it.

Dirt 2 chainging res to 3 screens = 3 black screens. (only tried once)
Fallout 3 = no 3 screen res.
Black shark = working but aspect all wrong.

I shouldn't have to go through hoops and buy extra bits to get a $600 card to work.
And the box should have had in huge writing.
Need Display port monitor which you can't buy to use 3 monitors !


I have always bought Nvidia but thought I would give ATI a try seeing as they were so far ahead........
Sorry.... The FPS are fine, but its eyefinity which made me willing to give ATI a shot....
And from where I am sitting I shoudn't have....


Now to re-enable my Nvida card and remove the VGA adapter before the black screen flicker drives me insane.......

You can try flashing your card with bios that up the voltage on the DP port. It's a problem t hat was unforeseen. If you are having trouble getting the right res for your monitors, try using a EDID mask on the DP -> VGA monitor: http://www.widescreengamingforum.com/forum/viewtopic.php?f=64&t=17635

You really cant expect smooth sailing with "new" technology. When it's a pain in the butt to just get proper widescreen on on a single monitor with alot of games, why would it be easier to get it with 3 monitors? I know that's not how it should be, but we live in reality.

[TheVulcan]

I might give the BIOS flash ago.
Although the Adapter gets pretty warm as it is already.

Also when booting it shows the BIOS info on only 2 screens. (DVI)(VGA)(blank)

Thats fine but as soon as Windows kicks in the main screen goes blank. (DVI)(blank)(DVI)
Unplugging the adapter for a second is the only way to bring it back.
Screw that every start up.

You really cant expect smooth sailing with "new" technology.

I can and do.... Products shouldn't be released until they know it will be smooth sailing.
You can't tell me ATI didn't know how crap it was going to be for everyone when they released it.

I have no problem with it requiring a Displayport Monitor when no one has them.. (chicken & egg story)
But I bet 80% of people who bought it for Eyefinity when it came out got caught out by this.
A big bold sticker on the box saying Requires DisplayPort, would have cost sales.
But that would have been respectible.

True, btw, what card are you using? You don't have your system specs in your sig.

I'm having problems with eyefinity. I was glad once I read that a dp->vga worked so I wouldnt have to spend $100 for an active dp->dvi converter. After it arrived, I was happy it worked but soon problems followed. Here are my monitors, I have 2 Samsung 2253bw hooked up through DVI, and a Samsung T220 in the vga->dp port. My setup is that my main monitor i use is the one on the very left, then 2 on my right. I'll show you a picture of my setup quick to give you an idea.


I would occasionally get the link failure. Sometimes when I try extending to the other 2 monitors, my T220 would only display at resolution of 640 x 480 and I won't be able to change it. Only way I can get it to work is if I disable the 3rd monitor, unplug n plug the dp-vga then re activate it. Then I can do eyefinity (5040x1050) and games would run fine. If I disable it, I won't be able to get it to work again until I restart my computer. I haven't tried plugging different ports/monitors yet. I'm debating whether if this problem is my cable, or my dp-vga converter, or just a general problem. I'll try flashing my bios later if that helps, but any help would be great.

I have XFX 5870

Displayport > DVI $110 AU.
Shipping to Australia $110 AU.
I thought screw another $220 AU just for Eyefinity..... I'll just wait for a monitor to die and get a new Displayport monitor.

When I saw the Display to VGA that I could get to my door for $50 AU I was happy.
Waited 3 weeks for it to arive..... Only to find it buggy as hell....

Sounds exactly the same as me.......

Had the same exact issues, I didn't have them on vista 64 bit but when I upgraded I did. After I got the new drivers it solved all the problems though.

[lm24hrs]

I could not get Eyefinity to work on my main install of Win7 64 with a vga adapter(did work on another install for a while) downloaded CC 10.1 yesterday & it's working very well up to now :rockout

[neosin]

I don't know why so many problems but my dp>vga works almost perfect on my 5770

remember you have to have your dp>vga as ur primary

I also have that 640x480 issue sometimes BUT all i hae to do is right click and bring up CCC and it automatically fixes itself :P

I'm gonna stick with my current drivers

btw anyone in Australia wants one I have a spare DP>VGA for $20 aud,

[Robbit]

I actually went back to the older driver, the new driver gives me the invisible mouse cursor bug when I try extending/eyefinity with the third monitor. I still haven't flashed my bios yet but I plan on doing that later today (Doubt it would work, seems like it fixes problems with the active dp-dvi). I can get 3 extended working by unplugging and plugging back in the dp-vga. Works every time, but as soon as I deactivate it and try reactivating, it will mess up

[sonicthemouse]

Hi everyone, first post etc.

Seem to have done the n00b thing and bought a DP - DVI adaptor for my 5770 but I'm gonna change that lol.

@neosin: I'm in Aus (Melb) and I'd like to get my hands on that adaptor, depending which one it is and if you've still got it. I'll PM you when I finish this post.

Anyways, I'm very interested to see how all this turns out.

-- even with all the issues you guys are experiencing... --
I'd like to see if anyone here has muched around with SoftTH (Software Triple-Head-To-Go)
I had it running across 2 separate nVidia cards (8800GTS + 7900GTO) and managed to actually get a fair few games to behave themselves.
It took a *lot* of editing of text files, but I could run Fallout 3, CoD2 and CoD4 and a handful of other at 4800x1200 across my 3 21" Dell LCDs, with the various aspect ratio fixing utilities for each game obviously.

The problem with this was the =performance=, when I built that system it was fairly decent (C2Q6600, 8gb Patriot Viper 1066, 650W Thermaltake, 1TB WD Black, amongst other junk), and even CoD2 struggled to pull a decent framerate.

Has anyone who's got it going with DVI + DVI + DP->VGA done any performance benchmarks or can give a basic indication of frame rates on common games?

Let me know, especially if the results are good! (Come on guys, I wanna hear about Crysis at 4800x1200 with full everything pulling 50+ FPS =P)

[BloodTotal]

Bought a Monoprice adapter, working fine on a dell 2209wa. haven't played any games so far but it works

[Lyrix]

I'm using a HP DP>VGA adapter wich works great for me!
No flicker or anything like that!

Here is the adapter : https://h10057.www1.hp.com/ecomcat/hpcatalog/specs/provisioner/99/AS615AA.htm

Cost me 37.- euro's
