4K HDR TV Sets Are Here...

Yes and no. Whilst high nit screens devour a lot of reflection, theres still something there and watching HDR even in a dark room offers a lot when the roll from a deep black to a middle grey is a seamless transition of light as opposed to banding. I can watch content side by side, well more one after the other in HDR and then switch to SDR and the difference is noticeable that way.

Don't the color gradients depend more on the bit depth?

PS. As someone who had spent a lot of time on the retail floor, I can pretty much guarantee that the "gradient talk" will not appear during a normal sales process. It's too technical for most customers.

As long as you record in log format your sources will be HDR ready.

Too technically speaking, HDR needs 13 stops and, if a given camera doesn't have it, ...
 
I want blacker blacks, but all my screens are set lo almost-minimum brightness, otherwise they just hurt my eyes after a while. The only reason I ever wanted my screen to be brighter is because of reflections. Can we get screens with less intrusive reflections and forget HDR as a display format? Thanks.
 
It seems there are a lot of misunderstandings about what HDR is, HDR is certainly not that your screen on average gets brighter.

In the old days (cue the violin ... then the drums ... then the bass), Sony's Trinitron tube reflected the light differently (a smaller center area) than the spherical tubes used by their competitors. The rear projection TV's actually had a lot less glare but their screen was far more vulnerable to kids and pets. At one of the stores where I worked, someone developed a thin plastic screen cover that was Velcro'd on. Naturally, it produced a horrible glare but parents thanked us for having it. Finally, most RPTV's put a similar plastic cover on. It made the projection look more like a tube TV, the look they were used to.

I am pretty sure the minimum spec for HDR playback is 10 stops, not 13 stops. And given that the HDR displays will be 10-bit, you should be shooting 10-bit or higher color depth.
 
I suppose the next question would be what cams can shoot 10 stops or higher?
DVX200, FS700, C100, C300, FS5, FS7, GH5, FZ2500?

Art Adams, in the linked article, says it's 13.

In any case, a few faux four kay projectors are out ... technically, it's a 2.8K DLP chip that has a pixel shifting technology to deliver a claimed 4K resolution.

They also claim to be HDR but one would have to see how the stated brightness checks out in real life.
 
Most of the current HDR video standards also state a minimum of 10-bits color depth, so 8-bit footage won't really cut it.

I wonder how many of these HDR TVs are able to reach 1000 nits brightness while maintaining proper black levels ?

But he doesn't state which HDR standard he is referencing. So far I think there are 5 different HDR standards for video. ( this will probably be a battle of the HDR standards until one of them wins out )

So, it's faux four kay, faux HDR, faux everything .. but it's under $2,500 and it's a projector ... as Hegel (or Marx or Engels or Stalin) once said, quantity has a quality of its own ... in this instance, if you can get 4K on a 100" screen, you're doing all right

I'd reckon none until the laser powered units come out and, these days, one needs to go upmarket to find them. That said, a lot of folks with projectors have separate rooms/basements dedicated to home theater and those are designed to allow as little ambient light as possible.
 
Depending on the image, that's not bad at all, boys. Unless/until 90"-100" quality panels get affordable($5K-$7K), projection is the only way for me to go "up" in my den set-up. I have a 92" rear projection Mitsubishi DLP(the last one they made). The size is pretty good(you always want a bigger screen), but the picture is disappointing by today's standards. My GF doesn't get why I like to watch movies, etc. in the bedroom now, instead. I have an LG OLED in there. OLED, HDR, built-in Netflix, Amazon, wipes your butt, etc.
 
Sony 75" OLED pricing has just been announced - $20,000 MSRP (and it looks like $18,000 MAP, which is what some stores are advertising). Not in stock yet. Darn.

Or one can pick up Vizio 75" LED HDR M-series for $3,500.
