After updating to 18.3.4 2 of my 4 monitors are now flickering. I have switched the cables around to see if it was just 1 card or if it was the type of connection, and to remove the possibility of loose connections.
OS Windows 7
AMD 8 core @ 3.2G
Cards 2x Radeon 7770 HD
2 monitors connected by HDMI (no flicker) ASUS 22W 1920 x 1080
1 Connected by DVI to HDMI LG TV 1366 x 768 flickers
1 Connected by DVI to DVI emachines 22W 1920 x 1080 flickers
changing connections changed which monitors flickered only the DVI connections are flickering, unfortunately I can not change the DVI to HDMI as the cards only support 1 HDMI each.
also the CPU is now running warmer, before update avg temp while playing Planetside 2:
CPU 62 F
Card 1 95 F
Card 2 75 F
Game on monitor 1 or 2
if game is on 3 or 4 Swap card temps
Now CPU is averaging 77 F
Card 1 104 F
Card 2 80 F
cards are not bridged as you can not connect monitors to second card when bridged.
