hereby asking some advice -
I recently built a new secondhand rig:
AMD Phenom II X4 965 Black Edition
ASUS M4A78
4Gb kingston DDR2
radeon R9 270
etc
Problem is that I'm having minor flaws in graphic card output. Namely, DVI to monitor has flickering pixels occasionally, green ones if there's some black background and purple/pinkish if background is white. Not too much, mostly on some black graphics, for example if I google for "black" and check images, like one third of the previews (the ones that have more halftones) are flickering a little, the worst of them dashing a full green line for a split second on screen. There's lot less flickering on white surface, but it occasionally occurs on some page menus or similar.
I experience a problem with hdmi output too, there's a strange flickering "faze shift" going on on some parts of the screen, like a strict line drawn from 1/8th (1/10th?) of screen's upper or lower part. It does not occur on still scenes,but when there's fast moving background, pretty much always.
I had my dvi cable in dual output, and there the flickering was considerably worse. Single link suffers less. I was pretty sure its the dvi cable, but now I do'nt know as hdmi has its flaws too. I sure could be faulty video card but I'd like to eliminate any other reason before I go by new one. So, I have some idea's of my own but please spare me your's.
Oh, and I tried both vlc and potplayer with their built in codecs, and I get the faze shift with any format, even flash from youtube.
what to test, what to check?
