You cannot change the firmware to equal an Infocus 4805. You're confusing the Infocus 4805 with the 4800. Two different classes of projectors. You can change the X1's firmware to make it a Screenplay 4800, but not a Screenplay 4805 (they're totaly different projectors). Big big difference. The 4805 is in another league than the 4800/X1. It has no white segment, a faster color wheel, darkchip2, etc.
I owned both an X1 with 4800 firmware and a 4805 projector. The X1/4800 has much more washed out colors than the 4805, much weaker contrast, poorer color accuracy, clearly poorer blacks, poorer shadow detail and isn't nearly as bright as the 4805 (despite what the specs say). The X1 has a white segment; the 4805 does not. The 4805 runs about $300-$400 as is true 16:9 native. The contrast is upto 2200:1 calibrated at about 600-750 lumens. The X1/4800 calibrates to about 800:1 contrast at 350 lumens. The 4805 can be converted to true 2.35:1 aspect ratio with an anamorphic adapter (which gives about 20% extra brightness to 2.35:1 films if VC is used). The X1 can only be converted to a true 16:9 projector with the same adapter.
Anamorphic lens on an X1/4800 = about 5-10% overall improvment.
4805 = about 75-100% improvement over an X1/4800 even with the lens.
So, the 4805 is about twice as good overall, maybe more.
