I have 3 displays. A Dell 21" IPS LCD 1680x1050. A HP 24" LP2475w IPS LCD 1920x1200 and a Panasonic TX-P50G20B Plasma HDTV 1920x1080.
When all three displays are connected Aero/DWM will randomly crash. The error reported is.
Event ID 1000 Faulting application name: Dwm.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc541 Faulting module name: atidxx64.dll, version: 126.96.36.1990, time stamp: 0x53bd5dfb Exception code: 0xc0000005 Fault offset: 0x0000000000593bf9 Faulting process id: 0x133c Faulting application start time: 0x01cfb3ebc3d612da Faulting application path: C:\Windows\system32\Dwm.exe Faulting module path: C:\Windows\system32\atidxx64.dll Report Id: 75079c81-1ff2-11e4-a13b-448a5b2b8452
If I disconnect either one of the displays I get no crashes. In order to use my HDTv I have to first disconnect the Dell LCD. If I want to use the Dell LCD I have to disconnected or turn off the HDTV.
I have tried 'clean' installs of ALL of the drivers since around April/May when the system was built. I am using a Sapphiretech R9 290 Tri-X Non-OC.
Motherboard is an MSI Z87-GD65 Gaming with latest BIOS.
The PSU is a Thermaltake 1000w
CPU is Intel 4770K
Operating system is Windows 7 Ultimate 64 running on a Samsung EVO Pro 256GB SSD.
