Okay, so i was just browsing for some cool wallpapers and suddenly outta no where a gray line appeared, a single horizontal straight line on my Samsung CFG70 which i bought just a week ago, it was working like a charm without any issues but suddenly this line appears, i will be sharing the photo to show you what exactly it is, and i also wanted to ask for any possible solution or should i just RMA it, and can please some one tell me what exactly the issue is, is it dead pixel or something else,
I already tried Changing cables from DP to HDMI but nothing worked.
A few suggestions would be really appreciated. please help me asap, thank you.

dead pixels, apply warranty, ask for a new unit now or a refund of your money
