Fix Screen Artifacts By Editing DSDT On Sandy Bridge Laptop

To fix the screen tearing, white lines, artifacts appearing on the screen after monitor sleep wakes, we need to edit the dsdt on our Lenovo G770 Sandy Bridge HD3000 Laptop.


  • It is possible for this to work in WINDOWS 7 ??? Why everywhere is mac OS ? I have the same artifacts problem with an intel i3 2330M @ 2.2 ghz, sandy bridge… so should I install Mac OS on this laptop?

    • If you have artifacts on windows 7, try to install driver again for windows 7. You don’t need to install Mac OS.
