Do you think it would be better to get the Seymour uf or xd screen material? They are sending me samples. I do want the best hdr and brightness that I can get. I am not worried to pay more to get a better screen material. Any recommendations?
Neither of the above can reach up to the gain level that assures one of a comprehensive level of HDR performance. Period. As such, if one is to go "AT", the focus should be on image quality, and the acceptance that....at least for now....HDR falls into the realm of those who can have enough gain
***. And
THAT does not include those whose Theaters (...or personal desires....) include having AT Screens of humongous proportions. Honestly.....the specifications of, and how HDR is being delivered is changing, but even with that, there is a wide gap between what can be had....and what can actually be done. The Future looks bright....but that's the Future, not the Present.
Also would it be better to just do a non AT screen as far as picture quality goes? I have samples of the spandex, Seymour uf and xd and Elite screens cinewhite screen samples coming to check out.
As I've stated....Image Quality on Spandex is certainly not lacking.....just the degree of gain required to assure that "any" HDR content will show as brilliantly as non-HDR content will.
As a good and valid example, currently the "accepted" amount of Foot Lambert to have coming off a Screen for effective HDR across most all Content Platforms is a "MINIMUM" of 40 fl....and preferably higher. But Hey....so very many do compromise on that.
In your situation, at 130" and with a 1.3 gain conventional surface, at a Throw of 13'-7" you'd garner 43 fl. Now your where you want to be.
AT Screens...the very few who do sport gain levels above 1.2, all have visual issues whereas the Weave or Perforations become very apparent unless one sits back at the "old school" ratio of 1.8:1 ......or more. That effectively makes a large screen become a decidedly smaller screen...the very anti-thesis of what the Big Picture is supposed to be all about.
Coming back around to your situation, your build would certainly look splendid in a AT-oriented design. Now you did already tip your hat toward the NX5....so therein lies both your desire for DLA 4K....and at a reasonable buy in. Personally, if someone comes to me before they bite, and AT is considered as being mandatory, I would refer them to the EShift Epson 5050.....for now, because it has the Lumen Ooomph to handle almost any reasonable size. (...at 130" with Spandex it can achieve 35 fl...) But I'm also a staunch JVC advocate & Dealer...and I install 'em whenever the budget and circumstances permit. But........I also do not send a Boy to do a Man's job as far as needed lumen output, so...../forum/images/smilies/frown.gif It is hard for me to justify specifying a PJ costing over $5K solely on the back of being Native 4K when such only sports 40K:1 Contrast and 1800 lumen. Nope....I steer people toward a x790r / RS-540u instead....and let the over $2K saved be justification for a future upgrade when PJ Mfg get wised up and give us all 4K @ 3000 lumen and 100K:1 Native contrast......for under $4K.
Now rest assured, I understand why people fawn over the NX-/RS-'000 series. We've all been clamoring for JVC to produce a Native 4K DLA machine. But they still have their own limitations, and some of those limitations are coming to roost on your Window sill right now.
Sooooooo....my advice would be to go with a conventional screen (...but choose....wisely! ) if HDR is an important factor in your plans.
PS......you can easily get what you want with a DIY Painted Screen and in doing so both save a huge bundle while waiting for another viable Screen alternative. (...had to toss that into the grinder.../forum/images/smilies/tongue.gif)
