UPDATE:
Moments after posting I got the idea of seeing if the built in monitor had the same issue as the LG curved ultra wide so I tested it out. Nope. It does not seem to have this issue on the built in screen. I went back to the big screen and saw the artifacts within seconds. So, signal error? What can that be?


Original Post:
I am trying to figure out if this is a graphics card issue or something else. Out of the box I started experiencing what you can see in the video here.

Video of artifacts playing Starcraft 2

I love this laptop and I use it all the time so I really don't want to send it back but I don't need to. I've already completely uninstalled and reinstalled Starcraft 2 and I've also completely erased all video drivers and started over. No change. Changing the resolution also doesn't seem to resolve anything. Reducing the quality doesn't change anything. It will randomly go to a black screen while playing games. Just for about 2 seconds. So it's definitely an annoyance but because I don't really play serious games like first person shooters, it's not the end of the world. I just need to know if I need to send it in for repair or not.

Does it do the same thing if you're using the laptop screen for output instead of external display?

This behavior doesn't really look like what I'd expect from VRAM failure, but it could certainly be a hardware problem just the same. I'd suggest cleaning out your laptop thorougly to see if there's any change.
 
Well, that was my exact thought just moments after posting and I tested it out. Nope. It does not seem to have this issue on the built in screen. I went back to the big screen and saw the artifacts within seconds. So, signal error? What can that be?
