Hi,
A while ago I posed about an issue with my GPU in another thread. I never really made its own post thinking it was a straightforward issue.
Unfortunately its been a while now, and I am no closer to actually finding out what computer part I need to RMA.
Basically I used to have a GTX 980 and an Asus Rog Swift pg278q. I had no issues back then. Then I went and bought an MSI GTX 1080 Founders Edition from Amazon.
Soon after I got it, I got these annoying flickering on my screen. Not just while playing games, but when just browsing the internet. I tried a few things, and I finally figured that the GPU was faulty.
So I sent it back to Amazon saying it was faulty and MSI would not honor the warranty in Australia. I then bought the same GTX 1080 EVGA this time since they offer worldwide warranty, and ran into the same issue again. Then I decided it was my motherboard, since it did have other weird issues. But changing my whole PC incl the ram, cpu, motherboard, SSD, PSU I still had the same issues.
I tried turning off Gsync, and reducing the Hz to 60 and still had the same issue, though perhaps at a reduced frequency. Its very random, so its hard to be sure either way. I even removed nvidia drivers and went with the default microsoft ones without avail.
Finally I tried adding a second monitor, and since then I stopped getting these flicker issues. I can turn the second monitor off, and its gonna stay flicker free. But as soon as I set my display to single monitor flickering comes back.
Considering I have changed everything else, I really cant imagine it being anything else except the cable or the monitor. But it just makes no sense for this flickering to go away when attaching a second monitor. It sounds more like a software issue. And the fact that it only started on the first day after installing the new GTX 1080, makes me reluctant to try and RMA the monitor. I have a feeling if I were to try and RMA it, I would have issues with Asus accepting it. They dragged their feet a lot the last time I had to RMA it.
I don't even have a spare video card, or I would just see if changing the card fixes the issue. If that were the case, I would just sell this on ebay and get a different model if I have to. Can monitors even be incompatible with a GPU? And if yes, is it the GPU at fault or the monitor? Can I even use this as a valid reason to RMA it? The monitor turned 2 years old today. I cant even seem to find how much warranty this monitor has. I am hoping it is 3 years.
Can anyone here help me out with this? I am really not sure which direction to head towards fixing this issue.
