So I wanted to chime in. One of the questions that Scott asked Tyler was about light output of current HDR displays based on window size.
There are five HDR displays in this graph. Some 2015 and 2016 models. The names have been changed to protect the innocent. You will notice that 3 of the five displays go down in brightness as the window size gets larger. Two go the opposite direction. Which is better? In my opinion, HDR bright pixels are mostly specular highlights, which means small areas of the image. Therefor I would say that 1-3 are better in that regard.
Display number two, in my opinion, is by far the best HDR display in the graph for many reasons, none of which this graph will tell you. Display number three is my least favorite HDR display in the graph and in general.
Another question Scott raised was about not having any UI on the display and using a tablet / phone device. This is probably more of a personal preference. I will provide my personal opinion.
1. I think the ability to have an external app be able to adjust all of the picture controls is really cool. Some really cool stuff is going to be done with this, especially when I get some free time.
2. I do NOT like having to use a tablet / phone to select content to stream.
2a. Today if I have a group of people watching Netflix, we can all look at the TV and make our suggestions. In this new system, you have to huddle around the tablet.
2b. There is no tactile feedback. If I am in a dark theater and i need to look at a touch screen, the image will get bright and the IRIS of my eye will close to compensate. Then when I look back at the display, it will take time to re-adjust.
2c. With the R65 and other manufacturers displays, you can plug in a USB drive with content and play it. I have found this useful, especially with courses I take such as FXPHD.com We have not found a way to play them on the P series. I will concede that this is a niche feature, but its how I plan to release a version of my test content this year before I release a UHD BD product next year.
2d. While I mentioned that some cool stuff can be done with their API interface for control, I still like to have on-screen menus. As Tyler posted a while back, there was previously a code to access the menus. That has been removed with the latest firmware, which I think is a mistake.
I personally will not buy a display that uses a system like this where I can't view the content on the display itself. You could use an external box with apps on it, but they currently don't support HDR.
Again, these are just my personal preferences. If you are the type of person that is okay buying a new display every year or two, then many of the 2016 displays will hold you over nicely for year or two while things get sorted. And you will get plenty of HDR enjoyment today. If you are the type of person that buys a display and wants to keep it for 5+ years, then I would wait another year or two before buying a display.
I also agree with the stand VIZIO made about the UHDA Premium program. This is a logo program that is made up by some parties with a vested interest in having a logo program. To be fair, there are others that are part of UHDA Premium that actually want to raise the quality bar. Just because a display does not have the logo does not mean that it is not superior to a display with the logo. I believe a logo program like this needs to created by an independent 3rd party with no vested interest in what passes and fails. The UHDA premium program is a pretty low bar to pass. THX, for example, would carry much more weight in my opinion. Spears & Munsil could create a logo program, but I don't believe any consumer dispaly would pass it today. :-)
