There is suddenly a dot on the screen of my laptop. It’s not that big. Just the same size as a period. When my laptop is in the usual position (L), the dot looks grayish. When I move the screen a little forward to form an acute angle with the keyboard, the dot looks white. I searched the web for an answer but all I can get is stuck pixels. I tried some solutions but it’s still there. What could it be? Should I worry? What can I do about it?
Sounds like a bad pixel. I have a couple on mine. Doesn’t affect what I do with my laptop.
Yes, you have a stuck or dead pixel. There’s not a lot you can do about it, but there’s not a lot it’s going to affect you.
Well does it grow? Or spread? Thanks guys.
I know someone who got a discount on a good monitor because it had a bad pixel. He’s had it for years and it’s never gotten worse or spread.
Are you 100% sure it’s not some foreign object stuck on the screen?
It’s not an infection, it’s a manufacturing flaw. A screen with one bad pixel is presumably more likely to have others that are going to fail, and additionally pixels near the bad one are probably more likely to have the same flaw than others elsewhere on the screen. So in that sense it may “spread”, not because the bad one causes good ones to go bad but because they were more likely to be made with the same flaw.
There’s nothing you can do about this except wait and see, or replace the screen or the whole machine.
On dell monitors at least a single stuck pixel is warranty-able.
Maybe you should check with your computer manufacturer if it’s still fairly new.
Do stuck pixels appear after some time?
There are methods to fix stuck pixels – none are guaranteed, several could make it worse.
One is to “noise flood” your screen, which will essentially play a full-screen video of that old antenna TV fuzz on your monitor for a few hours. This is relatively harmless, but barely ever works.
The other method is to take a spoon and a dry rag, put the rag against the pixel , the spoon on the rag over the pixel, and GENTLY apply pressure while rocking the spoon (or marker cap, or other round-ish object). This is not a guaranteed method. THIS HAS A CHANCE OF KILLING EVEN MORE PIXELS. It has worked for me in the past, but only do it if you were planning on replacing the monitor if it didn’t work anyway. Even then, only do it if warranty will not cover the stuck pixel.
That said, if the “stuck pixel” is black, it’s likely a DEAD pixel, which can’t be fixed (to my knowledge).
Well i’ve tried both methods and they did not work. But hopefully, both did not also made anything worse. Thanks though. I guess i’ll just don’t mind the dead pixel on my screen.
