Hi everyone, I have a problem on an elitebook 840 g2 notebook with the Intel HD Graphics 5500 video card. In practice, black gray vertical lines appear only on some web pages or on some windows pages, such as in the control panel. In all other windows, they never appear. I updated the BIOS, put an older one, updated the drivers to the latest version available on both the HP and Intel web sites, installed older drivers, left with the basic Windows drivers ... nothing. At resolutions below the maximum 1920x1080 this never happens, only on high resolutions. The operating system is windows 10, updated. If I use a linux live distro it doesn't happen, so I assume it's some driver problem or similar. I also put a small video of the problem, so you can understand what happens. Thanks and I hope to receive many answers!
This looks to me more like a hardware failure. If I was to hazard a guess (which I am never afraid to do!), I would say that there is a problem in the interface between the screen in the lid and the processor in the base of the laptop. A laptop can only be opened so many times. Sometimes, you can verify this by simply watching the screen while changing the angle of the lid.
Hope this helps,
hi, thanks for the reply. I was also thinking about a hardware problem, but it does it ONLY with some web pages and when I open certain windows, not always and above all by lowering the resolution (eg 100x900) it does not. For example, in the video, you can see that as soon as I closed that web page the problem disappeared.
