Following this thread for a few weeks and it was perfectly timed for our newly upgraded theater. Had a 78" DaLite permwall 1.1 or 1.2 in our dedicated room, but I wanted more! Upgraded to the Epson TW100 and so I was pretty sure a gray screen would do the trick for the added contrast I wanted. Enter CMRA and Misty Evening.
I looked, but as others have mentioned, the East Coast HDs and Lowe's don't carry Parkland materials, so I improvised and got a sheet of some glossy white coated hardboard with the intention of painting the ME on the glossy side. Also made a 1x4 frame to solidify the whole thing. I scuffed the glossy white surface and, following CMRA's advice, I primed it with Kilz2 before coating with 3 coats of ME. I used the groovy foam roller since I figured it would give few nap issues - and because I couldn't find any fine nap cotton rollers at the HD.
Upon mounting we watched a few movies and I eventually got around to calibrating with Avia. One word: WOW! As CMRA keeps mentioning to folks, you must perform this calibration before you can get meaningful info from the comparison. My suggestion: watch a few scenes from a well-filmed and transfered movie (Attack of the clones, Lotr, Gladiator) and get to know them with your current screen. Even take pics if that will help. Then try the new one (ME, or your favorite silver concoction, etc) and recalibrate with Avia before any viewing. Then revisit those favorite scenes and take more pics in the same conditions.
My settings from the old screen to the new ME screen were dramatically different and I was unimpressed with the ME until I did it. It wasn't bad, but it was pretty dull. After calibration, the contrast was improved enough that I'm sold. The colors aren't changed dramatically and I notice none of the white issues others have mentioned. I should point out that I'm running a Bravo D1 player with the DVI output (there's no other way to run this thing as the component output is pretty poor) and the ME screen does convey a slight 3D effect as CMRA said at the beginning of the thread.
I watched a few more scenes in Attack of the Clones and Toy Story 2 last night and the picture is outstanding. The Matrix and Se7en will be other standards to test the improved contrast (I don't own Moulin Rouge). Maybe by this weekend I'll get those notched off the list. I also have to buy Monsters, Inc and Shrek to see more of the 3D effect. I'll try to post some screen shots from my watching, both from movies and HDTV.
Concensus thus far from me and the wife: better than the Dalite and the contrast alone is worth the $65 invested. Now I have to work on a masking system...
