FAQ & Answers

• I had the same issue with my Acer Aspire 5740G. How I fixed it.

  Solution 1. Change the brightness of your screen (even though you'll see no difference when changing) then turn your screen off and on again with the key Fn+F6. Your brightness will change upon restart! It isn't very convenient but it's better than burning your eyes and it works with the right drivers.

  Solution 2. If you do not like the first solution then you can change your video driver to standard microsoft driver. This can be done in your device manager. There is no need to use Fn+F6 as it should work right away but you might loose your video performance.

  Hope that helps!
