horizontal green white flickering lines in screen

whitish-green horizontal flickering lines on the screen. its Lenovo legion y540, but that device was not in the option so I chose y530 coz its structure is exactly the same as this one. it has Nvidia GeForce RTX 2060. when I looked up the device manager, the display adapter Nvidia GeForce RTX 2060 has a danger sign next to it, but it’s updated. I don’t know what’s wrong there.

the lines don’t appear in the bios window. it appears from the logo itself when I start the pc.

I called Lenovo support, they think its software issue and windows need to be cleanly reinstalled again. but I read here and there that it could be the fault of loose screen connection as well, I don’t want to reinstall everything coz its a big step and it takes so long.

can someone tell me if its really a software issue or some hardware issue?

To check if is is a screen problem, connect an external monitor to the laptop and check its’ display. Even a TV can be used as an external monitor.

It appears from what you said that there is a problem with the Nvidia GPU given the exclamation mark so presumably the laptop is using the integrated Intel GPU as the display adapter.

In Device Manager > Display adapters > you should see two GPUs, the Intel Graphics and NVIDIA

Have you checked that the driver versions for both GPUs are as shown here? Click on the See Files link to the right of the drivers to see what the version number is.

To check if the drivers are up to date and also the status of the GPUs device go to Device Manager > Display adapters > right click the Nvidia entry > Properties > Driver tab > Driver Version and also to Device Manager > Display adapters > right click the Nvidia entry > Properties > General tab > Device Status. Do the same for the Intel entry.

See if you can switch to the Nvidia adapter. To switch to your NVidia dedicated GPU, Right-click the blank space on the desktop, select NVIDIA Control Panel to switch between two graphics, manually under Manage 3D Settings > Preferred Graphics Processor.

Try starting the laptop in safe mode and check if the problem is still there as far as the lines are concerned. Only generic Windows drivers are loaded when in safe mode so if the lines aren’t there it may be a driver problem with the Intel drivers as I’m assuming there is a problem with the Nvidia GPU.

device manager only showing Nvidia GPU, no intel. also, I can't open the Nvidia control panel for some reason. it just not opening. I checked with the official Lenovo site for a driver update scan, it says my machine doesn't require any driver update.

still, I downloaded intel VGA driver and installed it but I still can't see it in the device manager. whats wrong with it? why is it being like this?


@Aish A

Don't know the laptop so I'm not sure but check in BIOS to see what adapters it shows.

Also did you try with an external monitor or safe mode, you didn't say?
