Just bought this XFX Radeon HD 7990 - cost me over €450 and this is all I get out of it when I try to put any game into 3 screen Eyefinity mode. I set up a Eyefinity display using three identical Acer 24" 1080p monitors using CCC. The Windows desktop works without major problems (it does seem to forget presets when going from Eyefinity to normal Extended mode but that's a different problem). But when I go into any game I tried and change the in-game resolution to the Eyefinity one the three monitors go blank, start going on and off, I get that beeping noise you get like when the driver is installing and it says the screens may flicker during installation. This goes on continuously until I break out of game and kill it. Tried various driver versions to see if there was a problem with driver - tried the latest beta amd_catalyst_13.11_betav8 because needed for Battlefield 4 which is what I bought the card for and want working across 3 monitors!, Then tried the latest WHQL driver 13-9_win7_win8_64_dd_ccc_whql. Then tried the driver supplied with my card by XFX - 13.4. Also tried beta1 - amd_catalyst_13.11_betav1 None of them work and exact same behaviour in all of them! I have got a DirectX error after one game failed - "DirectX function "FindClosestMatchingMode" failed with E_FAIL ("Attempted to create a device with the debug layer enabled and the layer is not installed"). GPU: "AMD Radeon HD 7900 Series", Driver: 13.11 (13.25.18-131029a-164333E-ATI) Also when I tried to run the latest 3DMark FireStrike benchmark when desktop was in Extended mode I got a failure which I have never seen in years of running 3DMark benchmarks... "Window focus lost while running tests. Workload Single init returned error message: window_focus_lost: Display resolution changed" When I turned of Extended monitors and left just one and re-ran the Firestrike benchmark it worked fine. I CANNOT get any game I tried to run when the resolution is set to a large Eyefinity resolution. BF4 and others do the weird flicking and beeping (like as error above states the display is changing. The monitors actually go ON and OFF during this with NO SIGNAL input. Other games will NOT open in fullscreen mode - they seem to be stuck displaying in a window and while game runs the window top and bottom and the entire Windows taskbar stay stuck there during game even in single screen 1080p resolution. The monitors are connected 1 x DVI, 1 x mini-DP to DVI (supplied with card by XFX), 1 x active mini-DP to DVI ("Mini DisplayPort to DVI-D Active Single-Link Adapter" which worked fine with 5970 and is Eyefinity certified). Isn't this high-end dual GPU card designed for large multi-monitor gaming??? Why else would people buy more than one GPU only for multi-monitor!! WTF is going on? This windows install is only a few weeks old - no strange stuff installed at all.
