Calibration question
 
Will 4k or UHD content make video/display calibration simpler?
What specific considerations does higher pixel count add into the mix?

Pretty much nothing at all. A gray box is a gray box is a gray box.

People just have to be seated way closer to the TV than before to benefit from the extra pixels. (This really messes up the audio experience part of the equation of course.)

It will make a difference when adjusting sharpness. 4K will allow more detail and the ability to see smaller line detail on a test pattern. Sharpness adds noise to the edges of the lines and noticeable when viewing text. More sharpness may cause you to lose detail.

Even for sharpness ... at typical viewing distances ... it makes no difference at all. Only if you decide to sit at 1.8 x picture height or closer to the TV does it matter. And most people are never that close.

I haven't seen anyone that will move closer to their TV because it is UHD. Certainly not anyone that cares about their audio.

I'm going to get all near field monitors and sit with my nose touching the screen:D

If the finalized UHD spec. incorporates a wider color gamut and HDR, will that affect calibration at a fundamental level a all? Other than needing software that understands the new colorspace and patterns for it, the process should be the same. For HDR, I wouldn't think so either.

We already sit close, true UHD or 4k is most welcome. Thankfully its a ways away yet.

Rec.2020 doesn't include anything for HDR. HDR is coming from Dolby and so far hasn't been standardized by SMPTE or IBU, to my knowledge.

Also the Rec.2020 spec is a pipedream for color reproduction and in general simply a bad spec that appears to be marketing driven with little sound color science behind it. It doesn't even specify a EOTF (gamma function). Hopefully it'll never truly go into use.

The more I read about the pending UHD specification and the phased in way it will be implemented, the more I feel good about upgrading to a JVC RS4910 now. I want more than just a resolution increase, and the full implantation of a UHD spec seems a ways out....not to mention the content.
