Well, I've got a 70 inch 4k, and an HD projector that I throw an 180inch picture on screen to watch normally.

Having gone and viewed 4k projectors, I don't find the difference to be such a step up to drive me to upgrade.

HDR material is to me where 4k meets having value for upgrading.

I'm not debating on the question of whether or not there's better resolution. It's just a technology of diminishing returns. A 30 megapixel vs 50 megapixel doesn't mean you are going to gain much more visually if looking at it zoomed all the way out.

HDRs colorspace is a tangible advance in my opinion. No doubt that the 4k is important to the HDRs improved PQ.

I see your point, man. I perceive a difference, but deciding whether it's worth the upgrade is wholly subjective.

I see your chart and raise you this article:

Essentially, while it's absolutely true that there is a boatload more information passed through 4K, the human eye has a finite ability to perceive resolution.

Completely agree on 4k. It's quite noticeable with good source material.

HDR is an even bigger deal IMO but many current TVs still don't get bright enough to fully see it.

I can't really argue with that article. I feel like I can see the difference in sharpness, but maybe I'm just not far enough away.

HDR "upscaling", an interpolation algorithm, to to mimic HDR from non HDR shot sources is horrible horrible horrible right now.

Also, you're right, it darkens PQ way too much. It almost looks more like it's tinted brown.

It'll improve, HD upscaling made monumental advances.

If you have ever played around with video editing software, some of the more obscure conversion programs can take a vcr quality picture and get you close to HD. Of course, it takes about 3 days running nonstop doing multiple passes, and the file output size is enormous. Now a days you could upscale it, end up with a that giant file, and then convert it again to h265 to make it manageable for storage and playback.
