My 4K HDR discs include: Mad Max, X-Men Apocalypse, Tarzan , Snow White and the Huntsman, The Huntsman Winter's War, John Wick 1 & 2, The Martian, The Mountain Between us, Batman V Superman, and Wonder Woman.
With the new PJ and its updated firmware, every disc started and ran WITHOUT my intervention.
On the old PJ, I would sometimes have to attempt re-synching, turning everything off and on, going to USER mode,, then to NORMAL mode....trying all kinds of high speed cables, etc. For a couple of these titles, I was never able to get the HDR synched with the old PJ.
With the new projector, all I had to do was insert disc and wait; sometimes 30 sec, sometimes as much as a min, and part of that is due to the player. I still observed an occasional 1/2 second red and green bars, and/or momentary loss of signal at the immediate start of some of the movies. Not a big deal to me. Once started, it locked in with a beautiful, very good contrast/brightness/color. I am in "NORNAL" mode for HDR and all of these looked really very, very good to me.
I did match every one of my settings on the old PJ to the setting as was provided in the new PJ. [Since settings can vary a bit from PJ to PJ, I won't bother listing 'em all here.] With the PJ's running side-by-side, one fed by the Sony and the other by ROKU, I played the same YouTube Sony demo almost perfectly synched so I could compare performance. The New PJ was not as bright, but I made minor adjustment to the brightness and contrast on the new PJ, and they became identical to my eye. Running in movie mode, BTW.
It took me a long time to test all of my discs, since once I started them, I was too tempted to enjoy the beautiful picture, so I did...for at least 10 min per title.
The new PJ...If it is not brand new, they did a great job making it look brand new, packaged with all accessories like the original. The new PJ is 2 months newer than the old based on the mfgr date.
Now if someone sent their PJ in for update rather than getting an advance exchange like I did, why I think that is a good choice too. You won't be wondering if there is something different/ wrong about the replacement like: is it used? lamp hours? etc.?
The main thing for me is that the HDR is now working very well with my player.
Am next going to stream materials with the ROKU, and evaluate that, burning in the new PJ to ensure there are not problems. If all is well, I'll be returning my original/old PJ in a day or two.
And if you don't hear from me, everything is good and I will go back to being a lurker on the forum.
Thanks much to all the contributors!
