Eyefinity work ok on desktop but fails in games

[sehested]

my right screen turns of / looses signal?? as soon i boot the game.

my system is set up like this.

i have 3 samsung syncmaster A350 they have either support for VGA or HDMI

i use an active display adapter that goes from mini dp to DVI , the i have en converter from DVI to HDMI (so this monitor are hooked up with a HDMI cable.
then i use an HDMI cable som the HDMI output on the GFX
and the last monitor with is the one that looses the picture are connected from a cable that goes from DVI to HDMI, plugged in the DVI output on GFX.


hope u can understand me, sry for the poor english :)

happens with every game?

Only thing i can think of is wrong refresh rate! Lower than 60hz in windows and when starting a game it goes up to 60hz which causes an error in the adapter.

ive just looked in CCC its say my desktop res. is 1080p on all screens running at 60hz

What is your exact desktop resultion? 1080p isnt quite right for eyeinity.
It should be about 5760x1080 at 60hz (or slightly higher with bezel correction on).

Did you create en eyefinity group or just extended the image over the 3 monitors?

I have created a eyefinity group. and i use the res. 5760*1080 at 60hz

yesterday i managed to have picture on all 3 screen ingame, after i switched the old cable to the screen that turns off. the old cable where a DVI DL to HDMI.
instead i used a DVI SL>HDMI converter in the GFX and then a HDMI cable to the screen.
BUT after 2-5 minutes ingame its turn off again, then there goes some time, then its turns on again.

What do you have for PSU on that system? And what is the motherboard and CPU?

Specs are:

AMD phenom 2 X4 965

Gigabyte GA-890-GPA-UD3H

PSU: Corsair 520W


i have made som changes, now im able to launch games use eyefinity for hmm 5- maybe 10 min then it begins to turn of the screen again.

improvement from before where screen turned off as soon as the game launched.

The change i made was a DVI DL>HDMI cable i changed with a SL DVI>HDMI converter and a HDMI cable to the screen.


im using the DVI output, and the HDMI output+ the mini DP, with and active adapter without USB powersupply.

maybe a broken cable? Defective GPU ? if ALL screens turn off then maybe even PSU. hard to say

this confuses me..

you need an ACTIVE adapter, there are lots of passive adapters out there and lots of people have no idea what an ACTIVE one is. So they would sell you one as ACTIVE when its not.
