Radeon HD5770 and 3 Monitor Eyefinity CRASH

[pistonbroke]

Hello guys, new member here - looking for some help on an issue that has been killing me for 2 months.

Have obviously an older Graphics card - Rad HD 5770 and average PC - AMD Phenom II 2.6 gig / 8 Gig Ram / Win 7 Pro-64 bit.

Stable W7 OS, updated with all current windows updates

So... 3 screen Eyefinity setup has worked great for 3 years, with 3 x LG 22" monitors. Original Connections of the LG screens to Radeon Card were: 2 x DVI-D to DVI-D, 1 x Display Port via Active adapter (using USB port) to DVI-D. All worked great.

Decided to upgrade to bigger / better monitors in December '14 - 3 x ASUS VN279-QL, since they had small 8mm bezels and VGA / HDMI / Display Port Connections - Sounded Good..

Updated Catalyst Control Center to latest version (14.12 AMD Catalyst Omega) and setup 3-monitor. All 3 screens active in desktop setup with full resolution, no problem - so assume card & video driver good.

However, when setting up Eyefinity Group, as soon as I set the display group, and hit apply, Video CRASHES (no monitor support). Only reboot in Safe Mode and restore point back 1 will get me a display again.

Tried pretty much everything with no luck. If any one has had similar issue / and fix, would greatly appreciate hearing from you.

PS My gaming habits are all Racing games - Need 4 Speed / DIRT / R-Factor etc..

Thanks, K

have you tried installing older drivers ?
Make sure to uninstall the drivers fully with DDU
