Hello,

 

I recently replaced my laptop's screen and have noticed that there are now two upside down red letters, DT, permanently on the new screen.  I haven't been able to easily find anything on the back of the screen which might be causing this to appear.

Would anyone here be able to tell me if the two letters are from a flaw in the screen itself (so I need to buy another new one) or if it's something I can fix/adjust?  I am using Windows 10 on a Lenovo ideapad 320 with AMD processor.  Thanks for any advice provided.

It is a fault in the screen, the resemblance to characters is by chance. If it's a new screen, that many bad pixels should qualify for replacement under warranty, unless recently actually means outside of some specified part warranty period like 3 months.

not trying to make you fill dumb but, did you pull the protective plastic film off the screen before installing it?

 

those dots are drawn on the film.  not part of the screen.

ok i'll admit it!  I once replaced a screen in an ipad put it all the way together and noticed the exact same thing and said "CRAP! I forgot to remove the protective film."  i didn't say the word crap.

Definitely a good thing to check for, something I considered but dismissed as those dots coincide exactly with the cell matrix of the panel, and have characteristic fuzzy edges giving the exact appearance of leaking pixel sacs. Also the panel shows numerous other pixel and subpixel flaws, it just looks like a low grade panel.

However it would be nice if it did turn out to be a cover sheet, I probably should have mentioned it just in case...

that's because the panel has plastic film over it making the display not as clear as it could be.
