Pixel on my monitor that i just noticed

Solution
How does it appear on other backgrounds? Black for example.

If it's "stuck", it should continue to be purple regardless of the background. If it's dead, it'll be a variation of the background it's on.


It cant be seen on black/red, but it is seen easily on white,green
 


its purple on every background though, i thought dead pixels are black
 
Oh sorry, I misunderstood. I thought you meant it was no longer purple on the black/red backgrounds.
If it's still purple, it's stuck. There are some (epilepsy inducing!) freeware in existence that claim to fix 'stuck' pixels, but I haven't tried any myself to recommend.
