LCD issue or Stuck/Dead Pixels?

I bought a new gaming laptop from Lenovo in February and on the 20th March I notice a row of dots starting from the top left and finishing in the center of the screen. I've tried the usual fixes such as disabling and uninstalling my graphics drivers but the problem still persists.

This is how they look during a LCD test. Otherwise they appear to blend in with whatever colour is on the screen.

Are these stuck pixels or is it to do with the LCD its self?

Connect laptop to an external monitor or TV or similar.

If problem follows (appears on TV), issue is with graphics card on laptop. If it doesn't, issue is with stuck pixels/LCD screen.
https://www.jscreenfix.com/ might be of use for the latter.

Thanks Neil,

I have tried two external monitors and i cannot see the issue on an external monitor. Do the red dots in my image indicate dead pixels?

Dead pixels are usually black, stuck pixels are usually either red, green or blue depending on the state they were in when they became stuck.

It's very unusual to see a long row of pixels stuck like that, they tend to either be sporadic or spaced out, not in a big long continuous row/splodge like that. That what you've posted is more likely a damaged screen such as if you slammed lid down with some considerable force or if there was an object between screen and the keyboard/touchpad and the lid was closed accidentally.

As I say if it was a graphics card issue it would follow onto the external monitor. And it hasn't, so it can only be a screen issue. You can try jscreenfix (link above) and see what happens, but no guarantees and it won't help if the screen's damaged anyway.

I've just been on the phone to Lenovo and opened up a support ticket with them.

I don't recall slamming the lid down, i always close it as i usually would. The screen was fine on the morning of the 20th March and it was closed for two hours. When i opened the lid back up later that afternoon is when i noticed that row of pixels.

I have been putting the laptop back in it's protective cover that it came in as a bit of extra protection in my sleeve. Could that have accidentally damaged the screen?

Would fail the entire definition of "Protection" if the cover did that Wink
AndrewPSSP and JasonB gave kudos

Least my mind can be put to rest about what it is and Lenovo are aware. Everywhere else i've asked hasn't been too sure.
