Finally opened up the box and got my NX7 on the shelf last night.
I watched How to Train Your Dragon 2 (blu-ray) on it without changing any settings out of the box. I only adjusted the zoom/focus and position to fit my screen. No adjustments to convergence, brightness, etc. Oh wait, I did turn CMD off.
Initial impressions were that it's like I went from your standard theater (my Panasonic AE8000U) to a Dolby Cinema (a good one).
After the movie, I tried to watch a few short clips of 4K material, but ran into some problems.
When I played 4K files on my Zappiti One, ufortunately, I saw that the projector was being fed 1080p. Went through settings on the Zappiti and couldn't find anything. On the "TV System" setting, I had selected auto, but of the other selections, the highest it went to was 1080p, there was no 4K resolution listed.
Then I went to my Xbox One S, and it immediately said I had a 4K display and asked if I wanted to change the resolution. I clicked yes, and then the screen went blank and said no signal. I had to turn off my receiver (Yamaha A3050) and turn it back on to get a picture again - and that was the Xbox saying that the attempt didn't work. I checked the details screen, and it said my TV system was capable of 4K, but then said I wasn't able to do some other things. I went through some of the troubleshooting steps on the Xbox and got a few more of the items checked off, but most still said they wouldn't work. After this, I did get a 4K signal when watching Netflix, however, it was still not HDR. Zappiti is still just doing 1080p.
I'm not sure if I'm just not having the settings right, or if there is something wrong with 1 or more of my devices (or cables - Monoprice redmere). Any settings on the JVC (or the other devices) I should look at as a possible culprit?
Here's the initial detail on the Xbox:
Edit: Also, I did try putting the lamp in high mode before shutting down for the night, and the fan was quite loud.
