Hey guys
I owned a GTX 1080 Classified (it turns out this card is very identical to FTW, no performance whatsoever improvement) purchased in August. I had two times censored pic on Chrome (see attachment), after I close the chrome and re-open Chrome, it backs to normal. When I watch some Facebook videos, sometimes the first 3-5s video had 1/3 censored black random shape blocks on the top and then it backed to normal later.
And seldom had some flashing colorful rendering censored blocks on the desktop (When you overclock it too much while running the benchmark), it happened for 2-3 times.
I am always running stock speed. 
Please advise, I am considering getting a replacement unit since I need to get a thermal pad and I am also not very comfortable with changing the thermal pad myself.

I am using a 27 inch 4K 60hz Dell monitor which technically is not a high refresh rate monitor, but it doesn't hurt to give it a try.
I also had a question. I am using 3840*2160 with 150% DPI magnification. When the monitor sleeps, after it turns back on, the desktop resolution changes to 2K which is weird, I literally need to turn off my monitor and turn it back on and it will back to normal. Is it known as a Windows issue, Driver issue or it is just my monitor's problem? Thanks in advance.

The Chrome issue is related to the drivers.
As for the other thing, can't help you.
