lenovo y740 screen flickering after driver update

2020-11-20, 16:59 PM

This started a while back, the last good update was on 8/12/2020. After that when i updated my driver my screen started to flicker so i rolled back to my original driver hoping it would get fixed in the new update. Now after the new update it has gotten worse. I can barely see anything in my screen. I have to force shutdown to return the screen to normal and the flickering starts up again after the pc is booted up again or woken up from sleep.

There is a known issue with Intel UHD Graphics that could be causing the flicker, so I would recommend that you check it out just to be sure.    Also if you have just updated the driver for the Nvidia, make sure to update to the latest driver for the Intel UHD 630 as well.

Thanks for the reply, my system however never detects a intel UHD card in it, although i think there is one in it.  So , my laptop uses the NVidia card at all times.

update

I had a chat with lenovo support - waste of time.
verdict - "send the laptop for repair". 


as for now the stable nvidia driver for me is 452.06
newest drivers from lenovo site 457.20 and from nvidia site 457.30 - give display flickering. It happens often after sleep. 
system reset with windows reisntall doesn't help.

my question is - can it be that it is really a hardware problem with my machine or this laptop model. and the newest display drivers are "bringing the issue to the light"?

This has nothing to do with intel graphics. I experience the problem with no intel drivers installed, and the laptop is in dedicated graphics mode. that is I am using only nvidia graphics.
