I have noticed a dot on my laptop screen. The behaviour of this dot is changing under different background colors. I just want to know if this is a DEAD PIXEL of anything else and is there any fix for this. Here is some explanation and images...
With RED and BLUE background the dot becomes barely white:
With YELLOW OR WHITE background its gone and with GREEN background the spot looks BLACK:
Here is the strange thing heppening i will try to explain,
The conditions i have explained above are only applicable if the whole display is of one color and there is no other program open with white background (eg. any browser or file explorer etc).However if I open some program somewhere on screen (not full-screen) then the spot becomes white,no matter the screen wallpaper is green or red.
