I’ve owned this RS400 since they came out and this is the first week I feel like I really used it! I used The Martian to compare and I was amazed.
Ok so now, I have some questions on my setup that you guys (Mr 787) might be able to help me with. Settings and clarity to ensure I’ve got this right.
First the 820... I’ve got SDR/2020 selected for the output. Done. There’s a few other settings you can help me with:
1. HDR10+ I selected to Off (I see no value in it being on)
2. Selection for Color 4:4:4. It was set to off and I selected it on. The process performed a handshake with the projector and asked me if I saw the image. After two tries it worked. This is the preferred mode correct? The 400 can receive the full bandwidth 4:4:4 from 2160/60 I believe. Interesting that I get 2160/24fps at 12bit, the menu screen is at 8 bit color and 60, and other times on 4K content (like Netflix 4K) the color space goes blank (greyed out) in the rs400 info tab. Does this sound correct? My understanding of color space is very very limited to nil. I can double check and screen shot those for better clarity.
3. The UHD Netflix content seems to be taking advantage of the SDR/BT2020 just like the disc content. I used the 2.4 gamma with it and it looks good whereas the 85nit Javs import looks overdriven. Sounds right? I believe you mentioned that the Javs Import you only select with the NVIdIA or another streaming source other than the Panny right? Then this makes sense.
4. When using the Panny and Javs import 85nit curve, the colors really really pop (bright bright RGBs) but looks also over driven or ‘clipping’ - does this sound right? I know use 2.4 with the 820 just asking for confirmation it’s all working properly.
5. The Info panel on my RS400, when playing a disc or content from the Panny 820, where it says HDR, it always says YES? If the 820 is putting out SDR at 2020 shouldnt that say NO? Is this only looking at the HDR flag in the stream and I wonder if although the 820 is putting out SDR the flag still exists from the disc content?
6. Finally, the RS400 never reverts back to Gamma D. When I load the 820 and a disc, I expected to have to go in and reselect User 1 or the 2.4 gamma curve from Gamma D. I don’t have to. Even after both are powered off completely and back on. I thought this was a ‘thing’ for the 490/500/600 1st Gen projectors?
Anything else I can do to “Live my Best RS400 life”? I feel like this week, was the first time I’ve used the unit to its potential in 3 years. It’s frustrating but happy I’m here with it today.
Thx again to all that have assisted, esp Mr. 787!
I'll have you know, I was using Dreamliner long before Boeing ripped me off, but I'm happy to share the skies.
1) Not sure, but obviously if you are not outputting HDR it should not make a difference.
2) I have mine set to 4:4:4 but I did not see any difference.
3) I have not yet streamed any content at all with the UB820, so far, discs only.
4) Yes, the premade curves have trade offs. The brighter curves will clip highs, and the dark curves clip lows. You have to try a few curves to find a balance but I'd rather blowout a few highlights and actually see whats going on.
5) I noticed this too but have no answer. Perhaps the BT2020 is triggering the HDR marker.
6) Correct. The projector is technically seeing SDR from the UB820 so it does not trigger the Gamma D switch. When you switch in and out of the user modes (HD/3D/4K) it will remember your Gamma selection too. Glorious.
I need to do some testing with the UB820 on streaming and update my guide to strongly recommend it. Since I've only done discs I need to try Netflix HDR & Amazon HDR and see what they do and if you need to enable that "HDR/SDR Conv. (Network Service)" option. I want my guide to flow well but I have to make sure its accurate so I need to mess around with the UB820 more to know exactly what to change. It is very clear to me and anyone who buys the UB820 that it is the correct and single best player for these projectors and worth every single penny. It really wakes up the projector and removes the compromises. The premade Gamma curves are definitely a great place to start (and finish). I was blown away at how great they are, but to know it gets even better is what really sold me on the UB820.
I try very hard to eliminate owners bias and not post a bunch of puffed up hyperbole but the difference between JVC Gamma D and a premade curve is like a fast food hamburger compared to a Rib Eye Steak. The UB820 is like getting a giant slice of warm apple with ice cream after that steak!
