Philips user66666,

I have that screen and 3d is awesome, and active 3d gives me headache, so i can assure you that the 3d is great.

It may seems stupid but, i may have a solution for,you.
When launching a 3d movies go into the 3d menu and select side by side instead of inversed side by side. You may have configured inversed side by side from beginning and it might have saved it as your original choice=====> really hope this is the solution for you

Another thing, do you also have flashing ambilight problems when watching 3d movies or games?
