Colors banding issue

Anexel · Jul 18, 2015

It looks like theres no "antyaliasing" in colors, beacose I can see them being pixelated where colors change. There are also green square pixels that occurs in dark areas with black color.
This problem occurs everywhere. In games, movies, apps etc. I have set 32bit depth(not 16), I reinstalled drivers, changed monitors and cables but also no fix. My pc:
Core i5 4590 3.30 GHz
8 GB DDR3 RAM
Radeon HD 6840 1GB RAM
Gigabyte GA-B85-HD3
Chieftec 500W
Monitor Asus 22"
And some screenshots. From Dragon Age Inquisition before menu load:

I suspect this is GPU or PSU problem beacose those are oldest components in my pc. Also if banding is not visible on screenshots above then I can post screenshots from camera.

post screenshots from camera. try another monitor to see if still have a problem. the green pixels might be stuck pixels in your monitor which is where the camera shots come in to see them.

I try to make best picture, but my camera is old. To make it clear its not the picture compression on screens its just how it looks on monitor. Picture of desktop:

I tried three monitors and still the same. Also I first noticed this problem after changing monitor to Acer, a long time ago. I thought it was monitor, but recently I bought ASUS(much better than Acer) and this problem is not fixed.

as you also have onboard video, pull that radeon out & see if the onboard video displays the same thing as it is not a monitor issue if 3 different monitors have that issue.

Anexel · Jul 19, 2015

I did few minutes ago what you suggested and its still the same. Does that mean GPU is not the fault of this?

ffg7 · Jul 19, 2015

as onboard does it then not videocard problem. try another psu as you said it is an old component.

Anexel · Jul 21, 2015

I tried another PSU, 520W, but nothing changed. Im starting to think that this is monitor problem after all. This banding occures also on Windows loading logo when starting pc. All monitors I try had TFT/TN matrix. Maybe if I pick monitor with other matrix, maybe IPS, will this banding disappear?

ffg7 · Jul 21, 2015

don't know if the banding will disappear if you tried an ips or similar monitor til you try it.

Anexel · Jul 25, 2015

Well, just replaced ASUS monitor with new LG with IPS matrix. Issue is gone

Tron Legacy and other movies dont have banding like on screenshots above. Dragon Age Inquisition dont have those bandings. Only Dying Light still have them, but not so noticeable. Its probably game fault as game runs on mix of medium and low settings.

Picking up your latest answer, ffg7, as solution. And thank you for the help

this also happens to me, but in some cases it also happens in browsers, i notice it's stronger in chrome and in firefox, and on IE doesn't seem so bad, but i only had this problem when i got my new monitor, although i sent it to repair, they said there was no problem to it. I also tried with my hd tv with an hdmi cable instead of vga, but still same problem, here are some examples:

and it also happens in some games, where are dark areas i can see color banding too but i am already with 32-bit true color mode. Also tried replacing the gpu for an old one i had that i used and it's still in good condition, and same problem... So i thought it could only be either the pci-e slot on the mobo or some software problem, but already unnistalled all drivers and didnt solved a thing, and updated them all and same issue :/

ffg7 · Jan 25, 2016

does your motherboard also have onboard video?

darksiderpt · Jan 25, 2016

ffg7 :

I guess so, i already used the vga cable connected to it, are you sugesting trying it out with the gpu disabled?

ffg7 · Jan 25, 2016

yes as in pulled out of motherboard video slot to see if still have issue or not.

darksiderpt · Jan 25, 2016

ffg7 :

tried it right now, seems to be a software problem, but not a driver one because the intel hd graphics where up to date and still had same problem, thinking of installing a fresh windows version, at this point hardware is ruled out, so it can only be software, and drivers i tried a bunch of them and none did the trick

ffg7 · Jan 25, 2016

could do a fresh install of windows to see if that corrects the problem. start a thread in the correct windows version then put a link in this thread to your new thread. i'll see if I can't move your posts & mine into that thread.
