Asus laptop whitepoints?

Asus laptop has white dots on the screen but the white dots are only there when I open something black. I have this laptop for about 6 months and what can I do about it and especially that the dots go away

Are they really points or cloud-like areas? Maybe you should upload a picture.

There's a big difference.

If it's really dots, it could be a stuck pixel. That's not bad, you can try https://www.jscreenfix.com/ to make the pixel fit again.

Otherwise it's a dead pixel. It's hard to save him again.

If it's cloud-like, that's called clouding. Clouding is normal with monitors. Just google it.
