Hello,
I just got a 144hz 1080 27inch ASUS monitor, this is my 3rd, I had to send the first 2 back because of dead pixels. All 3 of them had small horizontal lines on the bottom 3rd of the screen. I mostly only see it on white backgrounds, while gaming or watching videos I don't see it at all. Is this normal or some kind of problem? I have used a old 1080 27 inch Samsung for years and have never seen these lines on it. They also seem to mostly show when I am looking right at the screen, if I change my angle a bit or get really close I can't really see it. I have tried a few display port and HDMI cables and all do the same. I am using it on the same computer with my old Samsung, so I don't think the GPU is a problem.

I have tried to take a picture, but can't get it to show up right on camera.

Thanks
