From the start, when I ramped up and begin PJ installs over RPTVs, the 20-HD attracted my attention on this Forum and The Big Picture DVD Forum for two reasons; 1st..., ambient light performance. 2nd..., crisp detail at 100"+. Both forums were rife with arguments about tolerating LCD's SDE vs the overly smooth "Film Like" image produced by DLPs. Since I was always intending to create systems for HDTV viewing as well as DVDs, and often in Family Room HTs, the LCD got my vote. NEVER did I regret that decision. The 20 HD was the one LCD w/NO SDE to speak of....unless you shot it onto a High Gain screen. That's when I started experimenting with Beir's much darker "Old Chrome" cut 50/50 with Ultra Pure White Flat. Like your ME, besides damping down the Lumens, the grey also removes any last traced of SDE.
No SDE, but lumenosity off the wall was cut to the equivilent of a 1000 lumen PJ to effect that result. But the detail...THE DETAIL! I could spot detail no one else could approach.
I chuckled at the arguments on both Forums. I laughed at the Panny 300 owners with thier attempts to mitigate SDE by defocusing, but in doing so bringing clarity down to DLP levels. I guffawed when DLP owners griped about ambient light distress, yet expounded upon "Film Like" image quality and color correctness. But DLP distratcors (LCD owners, of course!) touted "Rainbows' as intolerable, while DLP owners puked about tolerating any SDE at all. Seems everyone forgot about value/ performance ratios in lue of trashing the other's choice of PJs. And both were getting Killer machines for what amounts to a pittance.
Since then I've installed both. For my "Entry Level" Clients I installed X1s shooting onto raw, unpainted Parkland (smooth side) or on walls with Ultra Pure White mixed with a touch of the Old Chrome. I'll give ME the nod on those installs next. Seems to be the way to go.
But even though it is more costly and time consuming, I am convinced that undercoats of SMG is the way to go to increase gain without glare. and a really good thing to use if your image goes out beyond 110" Liike the 168" Monster Screen I'm about to install in New Jersey! Last time there. I mearly painted the prepped wall area with Primer, and using the exact same Toshiba (...and I mean the EXACT same one, sent on afterwards to me to Memphis) I shot my images from 16' away.
Lordy, was it spectacular to see an image that big look so good on just primer alone. I was to spec out a 20-HD, but between it's heat issues, and size, I thought that the Toshiba would suffice. The Client whole hearted agreed.
Now, after my shootout with you, I'm hedging on that decision. I miss my detail. Oh, I'm going to set up a 50 HD and try it out soon, both in Jersey and Memphis (4 of 'em actually over the next 30 days) but if the new unit doesn't represent a significant gain in sharpness in detail over the past, I'm going back to LCDs with a vengence. I would not have realized the difference between the two (the DLP's image IS great.) without the comparisons between your excellent screen shots, and my own.
The larger Truths.
Image quality is great with both, especially at the prices we pay today.
DYI screens can AND do match or exceed the quality of ANY comparable Mfg screen.
DIY screen's Color correctness can meets or exceed "out of the Box
That you and I can nit pick over subtle differences about image detail while showing off different platforms on painted walls speaks for itself......
CMRA, WE ARE THERE !
And soon, the DIY screen crowd will become a Legion of converts to the mindthink, "Cheaper IS Better, and makes your experience all the more special because of it. All the more so if your quality is BETTER than a MFG screen."
So now I must depart into another day of bringing joy to common folk with 'real world' budgets.
Aint it grand? !!!!!
