2060 Super, horisontal glitch lines only from displayport.

[maraxion]

So i got a second hand 2060 super in an rig I bought.
Installed it and i see that on the screen from the displayport I get tiny rift lines horisontally. I tried changing my 2 screen cables around, and then I got it on the other screen instead. On the HDMI output the signal is perfect!
Both screens and cables have been working with no errors on a normal 2060 for a while.

Tried updating the drivers and as above change the cables around. My screens is not new enogh to have displayport settings on them.

Any chance you could snap a photo? As-described, it sounds like bad RAM but, the HDMI working fine kinda distances that probability.
Have you already load tested the card (over HDMI)? -it works fine, no colorful/black/grey/white artifacts?



First thing that comes to mind: Dust/corrosion.

Every card I've had (that I've removed the lil video-output protectors on), after awhile gets dust built-up in and around the receptacle.
1st would try blowing it out w/ canned air (or a straw and some diaphragm power. Try not to spit ).

If that isn't helping, I'd consider stopping by an auto parts/home improvement store for this stuff:

Kursah, addressed the issue. This is now the only thread.
Since, the creation times for the threads were ~same, it probably wasn't OP's fault. Prolly ISP/VPN glitch.

Hi,
Post a screen shot
There have been office 365 same issues as well posted around here somewhere
Solution was to disable hardware acceleration :/

Peculiar that'd be confined to just one kind of video-out.
Still, I'd forgotten about that issue+fix.

Thank you for all answers.

Iv now had a few more hours to test.
As said before the lines only comes from displayport, and always get more of them if there is something on that screen being used. So that means i can run benches like superposition on the HDMI output screen flawless, but the display port screen wil have red lines.
Also the flaw is there if the card is cold or warm in terms of use, and as can seen on the video is quite quick.

I first tried sceen dumps but couldent see the flaw, then I tried video recording but again the flaw do not seem visable on recording of the source. So I had to make a video from my phone:
Screen tearing, vimeo:


In terms of more info Im running windows 10, refresh rate 60hz, resoluton 1080P. As said this is a 2060S, but on this same rig and screens iv been running a 2060 flawlessly until yesterday. I only put this 2060S in to test.

TrashZone: I tried that but this multi display and mixed gpu acc is not on my global settings list.

LabRat 891: Il take the card out when back from work and try your suggestion.

Hi,
Likely road hard and put up hot mining hehe
I'd return if possible.
If not hdmi it is.

I'd definitely try to clean the ports out and clean the PCB (around the DP port). However, I'm suspecting The DP port is damaged (like being tripped over, while plugged in),
and/or the port / controlling components have "cold solder joints",
and/or there are failed ancillary board components (like, from a monitor catastrophically failing*)
*I personally have seen a failed HDTV's PSU put 60VAC *into* a PC, through the HDMI connection. I imagine even worse can happen.
