Dell Laptop LCD - color slightly different on each side of screen
Ok I have a strange thing going on with my newish Dell laptop.
When I am looking at a browser, Discord, any normal windows app, I can see a line down the middle of the screen where the color is slightly different on each side. This is there no matter the color (though it isn't there or at least is very hard to see on white).
It is not there playing games. I need to double check later but I do not think it is there when using an external monitor.
I do not see it doing a LCD diag test (holding down D key while turning on laptop).
Is this a bad LCD or something to do with calibration?
