hi, I have an Acer Nitro 5 AN515-54-728C my screen was damaged and it showed a bunch of red pixels in that area, i brought it to warranty provider company initially they installed a screen which had some bad pixels and it was a little bit off-center, i rejected it then they installed an even more off-center screen to the point that I barely could see the blue highlight under the Taskbar apps that shows which apps are currently open but i found only one dead pixel on it. it goes dark when i open a dark or black windows on my desktop and after closing, it takes couple seconds to go back to normal it's so annoying i think they installed a cheaper downgraded model not the exact one (Device Manager shows that it currently is NV156FHM-NX3 Code: BOE090F), After the replacement, I also noticed that sometimes when the lid is closed, it turns on by itself and shows login screen, sometimes there is a notification sound and it turns off after a few moments, sometimes I have to open the lid myself and close it again to turn it off Whereas back then it used to be turned on only for Windows updates and when I opened the lid, it would show the blue screen of Windows being updated, not the login screen. I'm not sure whether this is normal or a new problem. they probably threw the original screen away by now, so i don't know what the default pre-installed screen model was. i was looking for it on the google that i came across this:
Apparently some who also had a AN515-54-728C model laptop had similar problem, he said his original screen model is LM156LF2F01 but these three websites say that the screen model for this laptop is NV156FHM-N4k: https://laptopmedia.com/laptop-specs/acer-nitro-5-an515-54-728c/

so now i'm confused, is there a way for me to confirm the exact lcd model number without having the original screen? i want someone to confirm and tell me what the original screen model was so I can eventually buy it with confidence and also explain why these websites said something else. Thanks.
