T570 - flickering on UHD display

Since a few weeks I see flashing on my Display. A kind of white lightning that comes only once in a while when I use my machine ... Have you ever seen that kind of thing? My screen is a UHD model. And my model a T570 20H9. my GPU are Intel HD Graphics 620 and NVIDIA GeForce 940MX. What should I do to try to better understand what is happening and potentially identify the cause ...

I do not remember having recently installed a driver update for the display.


thanks in advance

Re: T570 - flickering on UHD display

Hi! I don't know if it is related, but I have these issue and than now if I lower the brightness or unplug the power cord the sceen became scrumbled. And it is random to get it back to normal if increase the brightness again.
