ProBook 450 G5 Display issue

HP Recommended
ProBook 450 G5
Microsoft Windows 10 (64-bit)

I use this notebook for work and since some months I experiencing a very annoying problem with the display. On left side of the screen, several vertical lines appear which sometimes flash.
In Windows the problem occurs after the display has been turned off for a few minutes of inactivity, and in some cases even randomly while using it. After a few minutes, the display returns to working correctly.
Initially I thought it depended on the operating system, so I updated the drivers, Windows and even the bios (Q85 Ver. 01.14.01) to the latest version available.
Unfortunately the problem was not solved, on the contrary, I noticed that it also occurs in the bios screen, when I slightly move the lid back and forth.

The warranty expired in 2019, please help me.
