These are 10-bit, 4K displays with HDR support (supposedly Dolby Vision out of the box and HDR10 coming via firmware within 90 days or so), and Wide Color Gamut. Also, they are full array, local dimming (FALD). Depending on how well these review and test out, I would consider a 50" P series for my next display upgrade.

That's a very nice start. Now for a receiver that can handle this stuff...

Yes, when including the new HBR3 link rate option, DisplayPort 1.3 will enable a 4K UHD display to operate at a 120Hz refresh rate using 24-bit pixels, or a 96Hz refresh rate using 30-bit pixels.
...
You need DP 1.3 to get 10 bit color support. Display port 1.4 does not change any physical characteristics.
DP 1.4 adds support for Rec 2020 color space. DP 1.4 screens wont be ready for a while.
From AMD Reddit AMA: Will the cards come with DP1.4?
They will come with DP1.3. There is a 12-18 month lag time between the final ratification of a display spec and the design/manufacture/testing of silicon compliant with that spec. This is true at all levels of the display industry. For example: DP 1.3 was finished in September, 2014.
...
HDMI 2.0 adds Rec 2020 support, HDMI 2.0a adds HDR support but it does not have the bandwidth beyond 4k@30/10 bit w/o tricks.
TL;DR:
HDMI 2.0a gets you access to the new colors for movie viewing rates.
DP 1.3 gets you bandwidth for gaming but not Rec 2020 color space.

Finally, we have an honest man on the current uses of 4k.

When it arrived we mounted it on the wall and tested it with a few "movies" and tested it as a second monitor attached to his desktop.

Sitting on the couch about 2.5m from the TV we couldn't tell the difference between 1080p and 2160p. However, when we paused the movies, the still images were much better from the 2160p source files than from the 1080p files.
We could easily tell the difference between 720p and 2160p content but that appears to be largely a result of the way the TV scaled up the video. Further evidence for was that the 720p content looked better when we used software to scale it up to 2160p and then played the new 2160p clip. Ie., we had two 2160p clips: one downloaded at 2160p and one scaled up from 720p by the editing software: the scaled up 2160p clip was not as good as the native 2160p clip but it was much better than playing the 720p clip and letting the TV do the scaling.
When watching TV provided by the cable company there was no benefit from the 2160p TV - all of the HD content provided over cable was a mix of 1080p and 720p.
When using the TV as a second monitor for things other than watching movies/porn the benefits of 2160p resolution was the most noticeable: text and images were crisp and clear. My friend had previously has a 60" 1080p TV as his second monitor, with a 30" 2160p monitor as the primary monitor and there was a huge benefit to having the resolution of the new TV match the resolution of the primary monitor.

I'm picking out displays for the conference rooms here at work. I'm considering up to 84" for the largest room, with a ten seat conference table. My fears:
- 1080p will be too low resolution to look good
- 2160p will be too tiny to see for the people in the back, or too fuzzy from bad scaling
I remember reading that the scaling isn't so great on Windows 8 or Windows 8.1. Are things any better today?
Which would you choose for a conference room that spends a lot of time looking at Google Finance? 70" or 84"? 1080p or 2160p?

I know I'm not. And with all the research dollars thrown at this, I'm sure if there were an easy solution, it would have been implemented already.

'Nuther year or two? We don't have a DP spec implemented that can handle that yet do we, especially with HDR/10bit thrown in?
