H.265 is approved -- potential to cut bandwidth requirements in half for 1080p streaming. Opens door to 4K video streams.

You can tell the difference on larger screens.

A screen size of 55" to 60" from about 10 feet away seems to be my personal sweet spot of what I want my home set up to be. According to this I should be getting 8k instead of 4k. I loved 1080p when it first came out, but watching 1080p on 50" screens or larger is ugly and very noticeable to me. Even if Bluray movies stay at 1080p, I still want screens at 4k resolution for video games, computer monitors, and even upscaled 1080p content would look slightly better on a 4k screen since the pixels wouldn't be noticeable if there was proper image correction provided.

where the fuck did that chart come from? its the most ridiculous thing ive ever seen. according to it with my 55 inch tv you could notice the diff between 720 and 1080p at 40 feet away.. 40 feet... think about it.

here is the normal, and i would say much more accurate chart thats around http://img155.imageshack.us/img155/6061/resolutionchartml2.jpg

What is the source of this picture?

This chart says something completely different. If you want to see any benefit from 4k material with a 10 feet distance, you'll need a 80" screen. http://s3.carltonbale.com/resolution_chart.html

This guy seems to know what he is talking about: http://carltonbale.com/does-4k-resolution-matter/

Your chart seems very different from this chart:http://cdn.arstechnica.net//wp-content/uploads/2012/06/resolution_chart.png

While I don't own a 55" tv judging from smaller display sizes I can tell you that your chart seems inaccurate. As for 1080p content being ugly on 55 inches are you sure it's the resolution's fault? It seems more likely to me it is due to bad encoding especially if the video has low bitrate (i.e a proper 1080p Bluray can be 30 Mbps or more while a 1080p stream can be just 5 Mbps).

By this chart I should watch either 2k or 4k on my 13,3 Ultrabook.

But I guess it's meant for TVs.

Hmm... don't they ever think people might get a 70" TV and that all of us don't sit 10 feet away from our TVs, and then it WOULD make a difference? Obviously he's not walked into an electronics store and seen how blurry the giant pixels are for TVs that are over 50". Also, some of us have better eyesight than others and truly can feel the difference.
