Small white spot on my monitor, worse on bright screens

if it's the soft kind, it's usually pressure damage or a backlight spot and no software fixes that. check the warranty while it's still covered. a lot of manufacturers only replace after a set number of bad pixels, but a bright spot in the middle of the screen often counts on its own.

Does it show up as a single pixel stuck on white, or a soft blurry patch? If it's tiny and sharp it's a stuck pixel and a pixel fixing flasher sometimes revives it. A soft spot that's most visible on white backgrounds is usually the backlight, either a pressure mark or something pressing on the diffuser behind the panel. Software won't fix that one, so if it's still under warranty I'd send it back before it spreads.
