i just got some da-lite progressive samples, .6, .9, 1.1, and 1.3. I have a flat white wall i project onto, and floor to ceiling windows so ambient light is sort of a problem (no blackout shades though the curtains help). i do have the projector farther away from the windows though.
With the shades down, I did not notice a great difference on any of the samples. maybe because samples were so small? it was def not a $1k difference in viewing for me at least. even with the lights off and at night, the difference was not that great. projecting onto the wall in the dark looks fine to me so thought a screen would be even better.
i've been hearing screens make a huge differenvce, but from the samples i've seen, the difference is not that great. how big of a difference have you guys noticed with a screen vs your walls?
using a benq w1070, about 12' throw distance, white wall room.
