Purple Marks on Black Screen

[FlamingFury691]

There is a few purple marks on my screen and I would like to know first off, what are they, and second off if they are covered by warranty. I've linked a picture below they are visable in any low light games. Thank you for any response!

Hello @FlamingFury691 

Privacy Problem:

Please edit your first post and remove the image, crop the image so that only the screen is visible (no people!)

Do you have same error pattern on external monitor connected via vga/hdmi ?

Please report your results

Have done, they do not show on hdmi and my apologies for not cropping the photo.
