Chief also said the VCM heavy-duty mount (250lbs) won't work because the screw holes don't line up.
2) On YouTube, there is a review of the NX7 by Pan the Organizer from 3/15/19. From 7:07 until 7:30 it shows his dealer mounting the NX7 on the ceiling. What mount are they using? Pan says it's his old mount but is it a Chief mount? It sort of looks like a Chief but it sort of doesn't.
3) I too have a 3-5 second delay on video at the beginning of a movie, as Vaha commented here recently. I agree with others it's a handshake issue because I have different equipment than Vaha and I still have the same issue.
4a) True or False. Every movie I watch, I will need to start the movie, adjust the picture settings until the picture looks good (especially Picture Mode, Color Profile, and Gamma Settings) and either continue on with the movie or start over so the setup window isn't in the way any more? In other words, there is no "set-it-and-forget-it" any more? I know the answer is no, which is fine, I'm an tweaker so I will enjoy playing with the settings. It's just that this seems to be a fact-of-life with high-end projectors especially now with HDR, but I haven't actually seen anyone admit that this is indeed the way it is now and I want to see people say it in black and white. I realize there are many settings which can be set for Auto but not all can.
4b) I'm coming up with 106 different combinations of Picture Modes and Color Profiles according to page 31 of the manual. Natural has 6, Cinema 6, HDR10 and HLG 4 each, Film 2, User 1-6 has 8 before even considering the remaining 6 user Picture Modes can have 6 each custom Color Profiles. I probably did the math wrong but I can't be too far off. The point it, it's nice to have alot of choices, but who can explore 106 different looking pictures before watching a movie, especially for a tweaker like me. You know how us AV enthusiasts can be. But I only have so much patience and so much time. That being said, I can't be the only one who just wants to know that he's watching the absolute best picture he can! So my question to you all is, how do I find the best picture I can without exploring 106 different picture combinations at once?! This is not even taking into account all the different Gamma settings, Tone Mapping adjustments, Color Temp settings, and everything other setting that can be tweaked on the unit and on the player and receiver. Makes me almost want to go back to the 1970s when there were only five knobs on the TV; Channel, Volume, Hue, Color, and Picture!
5) Tell me if I'm on the right track on these Color Profiles:
HDR - seems to work best so far, but I have gotten mixed results, probably due to settings, and also I have the HDR Optimizer engaged on my Panasonic UB9000.
BT.2020 - seems to be the the de facto standard for newer titles? When in doubt, start with BT.2020 and HDR and see they look? Is that the best approach? If those don't look good then it's a gamble on the other Color Profiles? That's what I've found so far.
BT.709 - from what I read, seems to be best with older material or material originally meant for TV? (For ex, the BBC's "Oceans")
DCI - seemed to work very well on one of my movies but the HDR Color Profile looked better. I see some technical explanations of DCI online but not alot of talk in enthusiast circles. What's the deal with this one?
Video, Anime, Cinema, Film1, Film2 - are self-explanatory but am I missing out on anything? These remind me of receivers from the 1990s that had Hall, Jazz, Club and other horrible sounding surround modes, but they look good on the brochure before you buy it so the manufacturer feels obliged to include them.
Custom 1 and 2 - match them up with User 1 and User 2 Picture Modes which are matched up with Basic and High Luminance on the Panny 9000?
Custom 4 through 6 - for tweaking?
6) The picture sometimes flashes in and out, like the bulb is struggling to keep up, especially on bright scenes. I only have about 10 hours on the bulb so far so I will reserve judgement until after 100-200 hours but just wanted to comment.
Thanks for your feedback everyone!
1) I use a Peerless with a plate. But the Chief is the best mount out there and should have no problems with the weight.
2) No comment, haven't seen it
3) A handshaking delay is perfectly normal
4a) False. If you are using the HDR PQ setting with an overall mapping level set you should have many titles looking fine without tweaking. If you have a Panasonic UB820 or 9000 with auto tonemapping/HDR Optimizer it should be even more plug and play. Any title that lacks metadata, like Disney, you will have to tweak things to look their best. But the majority of titles do have proper metadata and look great with the same settings. I believe you mention owning a Panasonic 9000, I use my UB820 optimizer on with brightness set at -1 as a baseline. For titles that lack metadata I find the Panasonic easier to adjust things with.
4b) The key is to find the settings that get closest to accurate for what you are watching. For SDR I'm using a Custom setting with 6500K color temp, gamma 2.3 and brightness -1 (adjust the iris according to preference, I use -9 for scope with Auto-1 and -11 for narrow material with Auto-1). For HDR I'm using another custom slot, BT.2020 color (I prefer the filter, HDR is BT2020 without the filter), HDR PQ gamma (which is using a mapping level of 3) and brightness -3 (for HDR iris settings I use -3 for scope with Auto-1 and -5 for narrow with Auto-1). Once you find the setting that is closest to accurate for the material you are watching, you really don't need to worry about the rest of the color presets.
5) HDR and BT2020 are both displaying wide color gamut (WCG) found on 4K material. HDR does not use the color filter which limits it ~90% of P3 coverage, but offers more light output. BT2020 does use the filter and gives you over 100% P3 coverage at the cost of light output. I find the richer colors preferable and use the filter, you may prefer HDR. Either way these are what you will use for UHD material. For SDR you'll want look at what works. I found 6500K to work well.
6) Sounds like cabling/signal drop out
