Quick question: what screens are you folks using?
I'm looking at buying either the Da-Lite CinemaVision (1.3 gain) or the Perlescent (2.0 gain) screens to replace my 1.0ish gain blackout screen. If anyone is running with a Thumperized unit and the Perlescent I'd really like their comments.
Evidently I forgot to reset my unit back to quiet whites after using the projector for powerpoint and my eyes have gotten used to the brightness of the normal mode. Viewing the Tuhumperized on my homemade screen is distracting except when there is no ambient light to contend with. Unfortunately I'll have to deal with moderate ambient for entertaining.
This is a mod worth doing...if you have a Plus get on his list to have this done. Thumper has been great!
I'll post a more detailed review after I get the unit tweaked again this weekend. Black level is good, halo is effectively gone, colors are better and except for a minor problem being corrected the unit is quite a bit improved.
I just need to get the brightness back up a notch by getting a better screen.
PS Figuring 45" x80" screen...possibly a 52"x92" depending on budget. Oh and JXO you have private email.
I am running a Thumperized 1100 with htpc and a DaLite High Power (16x9 format/119" diag). Am very pleased. The Greyhawk may further improve blacks but brightness and color impact will suffer. I saw the Greyhawk at CES and felt it lost some of the punch that the HP screen imparts. The ideal solution would be a single screen case with both the high power and grayhawk screens.
Assuming your projector is a realistic 500 lumens (the stock projector is NOT 1000) and the high power is actually about 2.5 in gain. Your image should be about as bright as the following:
500/30*2.5 = 41.667 Ft-L.
I personally prefer to be in the 20 - 30 Ft-Lambert area, but you're not way too bright.
I would use an ultramat 150 (which is actually about 1.4) or da-lite pearlescent screen (which is actually more like 1.5) instead of the high power. This will but you about 25 ft-L. If you have a dark theater room than this is probably a better intensity.
However, if your in a brightly lit room, stick with the high power.
Just a note on the pearlescent - I had one of those with my old CRT projector (needed the gain for the size screen I wanted). I did not at all like the "sparklies" it created. Not bad at all during most viewing, but if you got a scene with real bright white light like a sunlight picture, it was noticable.
Make sure you can see one before you buy, IMO.
(I made my own screen with my DLP and like it better, though admittedly the gain is not there).
