Yup, in Seattle. Magnolia on Roosevelt just didn't have any good content being fed to their projectors/screens, so it was hard to judge anything other than ambient light rejection of screens.
Definitive had a LED DLP set up in 2.35:1 format showing 'The Prestige' (YES!); it was incredibly impressive, except the cycling of the LEDs still created a weird effect for me (no wonder color wheels/DLP just doesn't work for me).
Not really interested in 4k when content isn't widely available yet. Heck, they still won't release my favorite movie on Blu-Ray 1080p... & it's a Sony Classics picture! What gives!
Back to my main point: going into dealers & seeing for yourself isn't really useful for me here in Seattle-- the selection is so limited & then w/ the content problems I mentioned... all I learned was that the Black Diamond is better at scattering less light to ceilings than the Firehawk, but the former has a completely offensive texture. But I'm just OT at this point.
