So I encountered this problem two days ago, as follows; When im running the screen while lightly flicker, it seems like the brightness goes up and down as well, I messed with the brightness tab and it does it make a difference, the darkest areas are still dark as hell. I just reinstalled norton anti virus when all this started and changed one setting i didnt have on before, then it started.
Then I turned that setting off, deleted DODS folder and reinstalled all the content.
Not sure whats going on if you have any ideas or suggestions, id greatly appreciate (-=
