Title: Sony SRX-R800 phosphor laser projector contains 6 laser moduals.
Post by: MrPixels on Fri November 03, 2017, 12:45:00 AM
This is a first, Sonys new SRX-R800 series phosphor laser projector contains six laser modules. For the first time, Sonys cinema light engine is sealed. In theory, this should help maintain contrast.
Still curious if HDMI 2.0 has been added, so far no news on the inputs. Sounds like a nice projector.

Yes this is good news but still a lot of questions not only about there HDMI 2.0 inputs also how they handle HDR if at all from UHD Disc and more things.

The 10.000:1 on of sounds great but question is the Ansi Cr. that normally is not this good with LCOS.
I have never hear that one with big Lumen output have more than 350:1.

Also a Question is can be with a more aggressive Iris in the Lens the on off cr. improve or not and how much it will kills the Ansi cr.?
A Consumer LCOS can gain about good 60% in on off cr. when shrink the Iris in the lens.
That should boost this Pr. to above 16.000:1 on of and this if it works can be a ideal number at home.

How much off the listed 15000 lumens would one have to cut for such a gain in on-off contrast, you would think?

I expect to have with this modification only about 7000 Lumen may less so not "soo much more" than a Sony VW 5000 that had from beginning about 14.000:1 cr. and may Sony can/have increase this number already i dont know.

That need to be consider when talking about this new Laser Sony and do not forget the Sony VW 5000 have all the inputs we need  can do all what is need for home cinema and UHD Disc HDR 3D in a small quiet Pr.!
