All 3 monitors randomly blink in and out. It is worse when I am just logging into Windows, as in the YouTube video linked or if I go between Eyefinity and normal modes. Either more reboots or just wait and eventually it stops and I can work normally until the next reboot or game that uses Eyefinity
Mouse seems non-responsive while this is happening
sometimes the blinking pauses briefly and the systems responds normally for just a second or 2, then starts again.
There is an Oculus rift plugged into the HDMI port but unplugging it made no difference
I have disabled freesync on the monitors and the Radeon settings
reset Radeon settings to factory defaults
Stripped out the AMD drivers and reinstalled (AMD clean install methods)
tried the color depth at 6bpc.
Purchased Startech 'certified' cables. No change.
power saver and standby 'off' on the monitors
Previous setup on this card was 3 old Dell monitors with combination of display port and some DP to DVI adapters which seemed to work fine.
I have used ATI cards since `98? including Rage, Radeons and several All In Wonders. Would like to stay with AMD but I like to not have these types of issues more.
