Widescreen Gaming Forum

Hello,

I just got 3 new flatscreens for my pc and im having problems setting up 3x1 eyefinity.

this is my setup:

AMD Phenom II X4 965BE 3.4GHz
Asus M4A87TD
Corsair Dominator 16GB DDR3 1600MHz
ATI HD5850 1GB
1x500GB Seagate, 1x1000GB Seagate
Windows 7 Ultimate x64
Samsung Syncmaster SA350 x3

I have one monitor in the HDMI slot with a HDMI --> HDMI cable
I have one monitor in the DVI slot with a DVI --> HDMI cable
I have one monitor in the DP slot with a DP adaptor --> HDMI --> HDMI cable

Windows 7 shows 3 monitors in the display set up, but only 2 work at one time. One monitor is always "greyed out" and disconnected.
when i tried to save the settings, Windows says "Unable to save settings"

I checked the internet and every news/post i checked was old (2009/2010) and they say i need an active adaptor. I thought i had an active adaptor. I actually have 3 different DP adaptors and im guessing all are passive if none of them solve this problem. I currently live in China and every shop here has never heard of what i want, they all just show me what i guess are passive adaptors as they cost about £5 (8USD)

Does anyone have a work-around for this?

Many Thanks

Nips

You NEED an active DP-whatever adaptor, unless one of your displays has a DIsplayport connection. I'm sure you can order one from Europe. They're pretty expensive compared to passive adaptors, about $50-$80 USD.

Ok thanks

One more question: Would this setup work if i used a DP --> HDMI cable or is that the same as using a DP passive adaptor?

In your case, at least one display needs to be connected via active mini-DP to HDMI. The other can be connected with any mix of DVI/HDMI/passive mini-DP to HDMI.

Seeing as DP-equipped monitors are still in the minority, it' pretty lame that it took them until the third generation of Eyefintiy cards to include those active adapters.

Ok thanks. Ill find an active adaptor. Cant wait to get my eyefinity up and running!

Happy hunting. Yes, EF is pretty sweet.

So i have got my DP --> DVI adaptor, took a while to locate and arrive. I plugged it in and found that the monitor isnt recognised (generic Non-pnp Monitor) and the max resolution is 1600x1200. Have i spent £45 on the wrong adaptor or am i missing something really easy?

Err... I recall others having that same issue, but not sure of the solution. It could be that the adapter is a single-link DVI, which (i think) cannot do 1920x1080 at more than 60hz refresh rate, so see if your display is running a refresh higher than 60hz.

What is the brand/specs/model of your adapter?

The brand/spec/model of my adaptor, i have no idea. Things in China are just made without copyright etc. I got mine specially made from the factory, but as Chinese people dont communicate, i have no idea where or how. The actual adaptor has no marking on it except "Active" on the DVI end.

I have checked my monitors and this is the setup: (without eyefinity)

DVI --> HDMI = HDMI 67.5kHz 60 Hz PP 1920x1080 (Black border around screen, Can not stretch to fit monitor)
HDMI --> HDMI = HDMI 67.5kHz 60 Hz PP 1920x1080 (Black border around screen, Can not stretch to fit monitor)
DP --> Adaptor --> HDMI = HDMI 75.0kHz 60 Hz PP 1600x1200 (how can i change the 75.0kHz to 67.5 kHz? Maybe thats the problem?)

With eyefinity:

3x1 (horz) = 4800x900

I have also noticed that when using eyefinity, on some games i get pink pixels that really stand up in red sections of colour and on other games, the DP adator monitor will flash pink. The whole screen will have a pink tinge. Some times flashes on and off, some times its fine for a few minutes. When not playing a game, the DP adaptor monitor will flash on and off as if its installing drivers of something.

When checking for new drivers, Windows 7 found that the DVI and HDMI cable monitors are Samsung SA350's, but Windows thinks the DP adaptor monitor is an Acer S271HL

A pink tinge? That's pretty weird. Sound like the problems with that adapter are stacking up. The joys of poor quality control, eh? Since it at least show a triple-wide image (even though it's pink and low-res, it does indeed, seem to be an active adapter
- just a poor one. It's not the first; when Eyefinity first came out, many people reports poorly-working active adapters.

I know there are a fair number of quality models that have been reported as working well here on on WSGF. But since I've never had the need for one, I'm not sure which ones they are, and I have no idea where you woudl order them on or near your area. Perhaps someone else can pipe in and tell you where you can order a quality Active Adapter from Europe.

Hopefully you can return the one you bought...
