Windows 7: Flickering/Flashing ONLY in Software/Programs

27 Jul 2015   #1

Windows 7 Pro x64
Flickering/Flashing ONLY in Software/Programs


I try'd several forums to get this answered but no luck, i will try to make as short as possible:

When i installed the Asus 290x GPU (before i had a NVIDIA GTX960 FTW) i had alot of
VSYNC/FPS/Hz problems, screen tearing/flickering/Flashing everywhere, this was caused later on when i finded out reading forums and alot of Google by Aero Peek, turned it back on,
this never was a problem before, till i went from NIVIDIA to AMD...

What i still have is really annoying, i have 2 monitors in extended mode (one desktop, so NOT DUAL),
when i use Vegas Pro 13 or After Effects CC2015 WITH external preview monitor on
and when i click on media files (anything in the project from pictures till video) in the project like in AE or "explorering" for files in VP13 (auto preview play) then BOTH screens flickers (it's more flashing) like 5 times orso, everytime when i click a meda file.

I have no idea nomore what it is, googling, reading forums for weeks now but not this
"specific" flickering/flashing on extended desktop, even out of insanity i made a "fresh"
install of windows7x64, offcoursse no difference.

Windows on login screen have one little flash to, its not noticible while browsing but it
is there (FPS/VSYNC?!) the problems, i record with FRAPS and it is flickering like madniss
(the opposite what i see in programs, so that explains something) when i record with
one monitor there is nothing wrong or flashing, only in extended mode.

I tryd everything (as far as i know), from latest/older drivers, GPU-Z, MSI Combuster for
testing OpenGL, tested OpenCL with Luxmark, its flying the card, like there is nothing wrong.

See my specs below what i tryd todo to solf this, new PSU, new Cables (and tryd every thinkeble monitor set-up, tryd HD'tv's to), i had the Asus as said before, i returned that because it could be faulty, many monitor/analyzer programs, every possible setting in CCC, no OC in bios, every possibele BIOS setup, latest drivers for my motherboard offcourse, device manger/conflict says everything OK, memtest name it..

i did may had other one or the same one, well the Sapphire have the same, i really am stuck here
and most forums have no idea anymore to, last option would be somehting in windows or even my

My specs:
Asus P9X79 Pro
Corsair RM1000w (before Corsair TX850w v2)
i7-3930K Hexa-Core Processor 3.2Ghz (OC 3.8)
