I have found (with my projector W1070) that 1920*1080 @50, I don't have issues. If the GUI is set to 1920*1080 @ 23.98, once I stop the 3d iso, the projector gets stuck in frame Packing mode (hence the GUI is not right). I know you have a different projector now, but maybe try 50Hz

Can you also report output of:

Code:

tvservice -s

when you believe projector is incorrectly in FP mode. I'd like to know if firmware believes it is signalling FP or not.
