To editor - the title and the first paragraph do not agree with each other.

Good gawd: 8K broadcast testing? [dies massively] As if 4K isn't enough they are almost going beyond what the human eye can see in terms of resolution.

Yeah 8K might seems an overkill, but 4K definitely isn't. Just out of curiosity I've checked some 4K videos on the web, and the quality is amazing even when viewed on a 1080p screen. The difference is quite visible compared to HD, so in my opinion it wont be really necessary to upgrade to a 4K TV set to view in very high quality 4K videos...

Hi, sorry but this is nonsense.

The point of higher resolutions is to resolve more pixels.

Encoding at 4k is not a way of getting better encoding quality for a 1080p.

Encoding at 4k resoultion uses space to store details (subpixels) that cannot be displayed on a 1080p screen.

At any bitrate, encoding at 1080p will give better results on a 1080p screen.

What you are actually finding is that 1080p is a very good resolution, and the video you are used to seeing in 1080p has not fully exploited its resolution, whereas high quality demo samples show it at its best.
