Question Pixalated display after windows lock

[Guilherme Louzada]

After my windows auto lock or after I do (Win+L) my screen gets pixelated as the images attached.
Images gets like this in my laptop monitor and secondary monitor as well.

This doesn't occur before windows locking.

Already tried to:

1. Update drivers (Intel's and Nvidia)
2. Update Windows 10
3. Setting both screen resolution and image scaling to default/recommended

Could anyone please help?
