Legion 7i: Weird colors on external monitor after sleep?

Tech Support

After my Legion 7i wakes up from sleep, my external monitor always has messed up colors. It looks like its in some corrupt 256 color mode or something. Reconnecting the monitor or restarting fixes this. Really annoying, has anyone had this problem?

This is a good LG monitor which has never demonstrated this problem on my desktop PC.

The photo enclosed shows real photos of the monitor, on the left is the "messed up" version, on the right is how it should normally look.

External screen is wired to the dgpu. Im almost certain its an nvidia driver issue. Ddu your driver and try another version.

I think the problem not come from default lenovo nvidia driver but the geforce driver below 512.15.. thats why it shows weird.. the latest geforce driver version 512.15 released on 22 March fixed the weird brightness and other problem for 2560x1600 reso.

Sometimes my integrated monitor wont go to full brightness after sleep. So I would say its pretty much a Legion issue. Doubt it will ever get addressed, they move on and pump out the next model right away.
