Black, White stripes on the Lenovo Legion y540 17irh laptop monitor, what should I do?

Question

Lenovo

Good day gentlemen. I really hope for a useful answer and help.

In general, six months ago I bought a Lenovo Legion y540 17irh gaming laptop. The flight is excellent and everything is ok, literally 2-3 weeks ago white / black stripes appeared on the bottom of the monitor (all on the screenshots and video). The laptop is still under warranty, but has not yet been serviced.

I immediately thought of a cable, but I was confused by the fact that from the moment of purchase, the lid of the laptop opened 4-5 times , all this time it stood open on the table as the main computer and was connected to the additional one. monitor.
I also remembered that before the appearance of the bands, I updated the vidyuhi driver. I decided to reinstall, the bands disappeared for exactly 5 days. Then they appeared again, I decided to roll back the driver to an older version, the stripes disappeared again and reappeared a week later. I installed the last version of the firewood, nothing helped, the stripes remained and before there were 2-3 of them, now it's about 6-8, as you can see on the screenshots.

Also, for the first time as they appeared, turning off the laptop helped, that is, I turned it off, turned it on and everything was OK, there were no bands.
Also, they are somehow strange, on a black background of the browser / discord they are seen as white, on a light background of the browser they are gray, and on a black background of the desktop they cannot be seen at all.

In terms of temperatures, everything is ok, the video card is max 60-70 degrees, percent. in idle 45-47, in games max 70-85 degrees.

No other problems are observed, there are no friezes in games, everything is ok.

Please tell me what could be the problem.

Try to go into the BIOS (UEFI), if the stripes are visible there, then most likely the defect is hardware and it is better to determine it in the service, especially if the warranty has not yet ended. Perhaps they appeared from overheating of the matrix itself or from mechanical impact on it.
