I am pretty sure that it is monitor related, but I have a 1080Ti and it could be the card. I noticed some weird vertical lines, that do not cover the whole screen, they are very tight together and appear at random. They usually only appear in Battlefront 2, but could have sworn that I saw them on the desktop today and I did notice them in Intel Extreme Tuning Utility a couple times. I can not get them to reproduce anymore. I used to be able to get it to show up in Battlefront 2 on one of the loading screens. 
 
I have been recording games since this morning trying to capture it. I have also been trying to catch it on my phone, this has been to no avail. However, just a few minutes ago I was recording the game, with the XBOX app game dvr, and it happened for several seconds on the score screen. I went back and watched the video and it was not on the video. Does this mean that the issue is related to the monitor? I tried three different displayport cables and it show up with all three cables (so that eliminates a bad cable). If it was hardware related to my computer itself, it would have shown up on the video, right?

I had a card that artifacted when it was starting to die. It was the only card that did not last me more than two years and it was a MSI GTX 260,  when it artifacted I got lots of spots on my screen that looked like dead pixels but they would constantly move across the screen especially when I would move really fast in games, then eventually the entire screen flashed random colors and the card died.  You'll know if its artifacting it'd be very obvious.

Definitely not tearing. I know what that looks like. I'm trying to get a video on my phone, but now it wont do it where I wss able to replicate it before. It is really obvious when it does happen.

What monitor do you have?

PG258Q ASUS 240Hz monitor. Is there no way to upload an image on this forum anymore? Just add a link to one? 

Here is a picture of the issue. 

Was going to try my PG278q and see if it still has issues, but it is on a monitor arm. The issue is really hit and miss and never happens while actually playing the game.

With the intel extreme app, it was just like that picture, but only inside of the intel app.

Like which picture? I can't see your pics.

The second one you posted.

Try 120 hz for awhile.

Sure, but if it works that means the monitor is defective. After all, it should run at 240.

That does look like the monitor though, right?

I had the same issue with an Asus PG278QR monitor and had to RMA it and what a terrible process it was with Asus. I dread doing another through Asus and I actually wish EVGA made high refresh rate monitors...

That's what I am afraid of. I hate dealing with Asus and their RMA process. I also got a near perfect panel, no bad light bleed and no pixel issues. I am afraid to see what I get back with an RMA... 
 
Did your's look like the picture that I posted? 

Hooked up my PG278Q and so far no issue... I need more time with it to determine no issue though, as the problem was not consistent. It was not happening all the time. I am guessing a loose connection? Or, maybe that Gsync module is going bad. I honestly probably won't buy another Gsync monitor, it seems pretty much anything that Nvidia makes that is not a graphics card is low quality junk. Just my opinion though. 

So far no issues with the 278q. I'll run this one for probably a week and it there is no issue start the dreadful RMA process through ASUS. I was almost hoping it was a graphics card issue, as EVGA's RMA process is the best that I have ever dealt with. 

I think my display port cable was not going in the port all the way. I went to hook the monitor back up to do some more troubleshooting before sending it off to Asus. When I was plugging the monitor back in, the cable would click and feel like it was all the way in. However, I took a look, just in case, and there was some metal showing. I then re-positioned the cable and reinserted it, while actually looking at the cable going in this time, and sure enough the cable did go much further in the port this time. So far, no issues. I guess time will only tell.
