Placing a small sample of EN4K on your XD screen is going to give a big disadvantage to the EN4K, due to the lower gain of the EN4K. Of course with EN4K it is going to take more lumens to light up the same size screen compared to XD.
Agree with Mike
Projectors will get brighter over time thus I didn't mind getting the EN4K and giving up a good amount of gain. By the time I get my projector and screen unboxed we should have quad LED HID Fiber Optic Lightning Bolts technology so I'll be ready to upgrade

Also went with a 16:9 because I could always switch to 2:40 or whatever the next common ratio is by getting smaller side frames.
One thing I am terrified with the EN4K is the screen getting dirty. I fear the day Mark Sanchez or Tim Tebow throw an interception in the Super Bowl that cause us to lose the game...I can see a cup of Wild Cherry Pepsi coming in contact with the screen.
