I'm using an older monitor but it was fine until a few days ago. I had a desktop background that was red and it was perfect until one day is made weird stuff on my screen. Now in random videos where it is normally black; you can see red stuff.
Not sure what it is.
PS: I use a two monitor set up and I simply move the picture from the bad monitor to the good one and the red stuff disappears. Does this mean my monitor is bad now?
