HDR 10+ - Best HDR for projectors?

I'm in the process of determining  which 4K UHD player I will be getting and Panasonic's new DP-UB820  player with their HDR 10+ ,  sophisticated HDR re-mapping and HCX picture processor looks  pretty good I must say.   Of particular interest for a projector user is its ability to take HDR material  and re-map it to the level of nits that will suit your projector.    It will also be interesting to see how Oppo's own tone mapping  compares to Panasonic's   although  it doesn't look like Oppo  has  HDR 10+ certification yet.      No word yet on release date for the new player but most likely in the northern spring.

as the guy states one of the things i think are a bit of an unknown is just how this player based tone mapping will interact with the tone mapping already in all devices ?

 

otherwise a case of tone mapping on top of tone mapping ! which can result in unpredictable end result. ! 

 

ps re oppo they declared when asked that they were holding back on hdr10+ to see if gets some widespread support ... ie before they waste their time. so time will tell i guess ...

May be handy for those very early displays that don't have the nit levels available now ; otherwise glad were finally able to match dv for scene by scene metadata :) Just need some discs..

The nice thing is the 12bit upscaling in the panas that perfectly matches the 12bit processing throughput in the latest 7000+ models :cool:

 

Oppo will take their time if history is any guide Al. A bit like pana not having dv out of the box  ; dolby makes certification not so easy..

Noticed this comment at avs btw which makes sense :aww: {It was announced today that all the 2017 Samsung UHD players will be getting a firmware update for HDR10+.] Rather have the pana but - either of the hcx models..

The new HDR10+ standard seems to be a brought about by a collaboration between Panasonic and Samsung and have set up an accreditation process.  If the standard is widely adopted by display manufacturers , I would think there should be compatibility and avoid layers of tone mapping.   There is no way the consortium would allow Oppo to have HDR10+ compatibility before  Panasonic and Samsung release their own players (this is also a clever commercial play)  and to get it later they will need to be accredited .   Oppo might just choose to adopt the the identical process without calling it HDR10+.

With such influential heavyweights like Panasonic and Samsung  creating a solution for a clear problem with many HDR implementations,  you can bet it will be very well thought out and they will get some uptake - providing they don't charge too much for licence fees.

Almost no current domestic projector displays can give full justice to  HDR   - unless you go for Sony or JVC laser and $$$.

Yes Tasso ; was off on a tangent; why I  said displays as distinct from projectors ; the nit levels of early oleds were not to the level of current ones let alone led :) That said some projectors with high lumens and wider contrast do better with HDR than other lamp based ones ie JVC :ahappy:

Projectors in general can't really offer all the benefits of HDR... HDR needs a combination of peak luminance and black level that projectors struggle with.

Yes j ; As said JVC's with their wider contrast - deeper black levels - and high lumens are the go to projectors for HDR :)

You see comments like this in reviews

my tests showed contrast that competes with a Pioneer PRO-111FD plasma, the panel I still watch in my living room. Now that is some serious contrast!

Its all relative ; obviously a panel has nit level etc advantages as you say .

      Panasonic 65" Plasma Display
      By LWA Staff
      Item: Panasonic 65" Plasma Display TH-65VX100W
      Location: Len Wallis Audio HQ, 64 Burns Bay Road, Lane Cove NSW
      Price: $799
      Item Condition: Excellent
      Payment Method: Cash, Credit Cards, PayPal
      Extra Info:
      First things, first - this is Full HD plasma display, not a television in the conventional sense. There is no built-in tuner and there are no speakers but don’t let that discourage you.
      What have here is Full HD 1080p plasma with exceptional picture quality and lots of settings to tweak. Think professional display monitor. Spend a little time getting the calibration dialed-in and it still looks absolutely stunning and satisfying to watch.
      To make it really shine you are going to want to connect it to a decent source like the 2nd hand Oppo BDP95 Blu-Ray Player ($599) we have it hooked up to in the showroom PLUS your AV Receiver/Speaker combo to manage sound.
      It’s a decent sized thing too and (very) solid, measuring 1,554mm wide, 924mm tall and 94mm deep. You can be wall mounted or use it with the desktop stand.
      With the stand it weights little over 70kgs. When new in 2010 they were $13,749
      Ports & interfaces:
      Audio L/R in
      Component video (YPbPr/YCbCr)
      HDMI = 4
      PC RGB = 1
      RS-232 port - 1
      Freight: Freight is not included in the price of this item and is POA. We are happy to ship anywhere in Australia but this is a heavy Item and we will need to get a price to transport to your location.

      By terminator
      Item: Panasonic Microsystem SA-PMX100B  (with remote)
      Location: Gold Coast (Helensvale)
      Price: $425
      Item Condition: Used but rarely used, not a single mark, dint or scratch. 
      Reason for selling: Need the money, I have a bigger onkyo amp + spealers, sonos etc. so dont really need this anymore.
      Payment Method: Pickup - Cash, Paypal 
      Extra Info: i joined this forum to sell you this, to find it a good home. Also I can now learn few things off the forum. 
      This thing really sounds awesome, read the reviews online. 5 star from most people. The spotify functionality is great, unlike sonos, the spotify app directly talks to this stereo so you can use your familiar spotify app.
      You can pair this to other panasonic "ALLPLAY" speakers so you get a multiroom setup. 
      The panasonic app for android is easy to use to configure wifi connection etc

      Eoi - Panasonic Sa-Xr55 Av Receiver (Sunshine Coast, Qld)
      By Brazzwald
      Hi all,
      I used to be a frequent reader of this forum, but alas life has a habit of getting in the way to find the time.
      Anyway, I'm thinking of upgrading my system at home and getting an amp which has a few more of the mod cons, like HDMI. So gauging if there's any interest out there for my 7.1ch SA-XR55 Panasonic Digital Amplifier, with Dual Amp and Bi-amp, 2 optical and 2 coax digital audio inputs.
      It's had an easy life since I bought it new. Remote is in great condition and I still have the manual for it.
      I'd love to keep it, but I don't have the room or stereo set up (yet) to intergrate it into. Can be auditioned working, currently drives Dali Concept 6's and Dali Concept Centre, as well as other not-so-good surround speakers and sub. PM if interested.
      Cheers
      Brazzwald
