I would think you have good screen, unless a grey screen would be better to help out in the RBE, but I'm not sure about that.
Under 10 feet back from PJ to screen is pretty close, if you are seeing RBE, if you can maybe move PJ back 14 feet back, but you might not be able to do that, not sure.
Maybe you could get a ND filter, to tone down the brightness, sometimes that helps too, look in the w1070 thread of advice about that.
Now, how does the RBE effect you, does it give you headaches, hurt your eyes, cause eye strain, disorientition? It effect everybody a little differently. Where are you sitting, how far back. I notice if I'm too close to screen, I can feel a little disoriented, it's a slight light strobe effect, but if I move back a little I don't get it.
It's hard to put it into words, so do your best. Does it effect you where you can't get into the movie, distracting. Does it happen a number of times per minute, or 1 or 2 times an hour. I guess I'm trying to figure out if it's something you can live with, or soemthing that will "drive you mad".
If I move my head fast side to side, I can see the effect, but I don't notice it at all if I'm sitting straight back from screen about 7-8 feet back. At 4-5 feet from screen it's too much for me. If you do get a different PJ, let us know how you like it.
