New HDMI 2.1 Spec Includes Support For Dynamic HDR, 8K Resolution (techhive.com)

Posted by msmash on from the feel-bad-for-your-old-tv dept.

The HDMI Licensing Group has unveiled the HDMI 2.1 spec, adding support for dynamic HDR, 8K60, and 4K120. From a report on TechHive: To take full advantage of the new HDMI spec, you'll need a new 48-gigabit-per-second cable. That cable will also work with older HDMI 1.3 (10.2Gbps) and HDMI 2.0a (16Gbps) ports, but those ports don't support the new HDMI 2.1 features. [...] HDMI 2.1 adds support for the new object-oriented audio codecs -- such as Dolby Atmos and DTS X -- which can position audio events from movie soundtracks in 3D space.

    I'm sure there's a reason why someone might want 8K, but I've not even been convinced of the benefit of 4K yet.

      For movies, not much. There's definitely a wow factor in some of them but you quickly forget about it and just enjoy the movie.

      But for coding and web browsing, I found 4K to be a surprising win.

      The extra clarity in text is absolutely wonderful. With low-res screens I often find myself wanting to zoom in on text despite being able to read the small text without straining my eyes. When I got my first 4K screen I noticed I was no longer tempted to do any zooming.

    Really? 100Gbps ethernet? Maybe you should go look at the specs again. ONE Gbps is common at home, 10Gbps is common only in enterprise environments, 100Gbps is not common at all and usually requires fiber optics.

  3. Funny thing about 8K... by Locke2005 · · Score: 4, Insightful

    8K is TWICE the resolution of human eye, which can only distinguish about 4000 pixels across the field of vision. Higher resolution is only useful if you're sitting close enough to only see half the screen in your field of view! Point it, 4K is the point of diminishing returns in video resolution. At 4K, you cannot distinguish individual pixels when the entire screen is in your field of view. Higher resolution for a TV screen is pointless. Higher resolution for a camera only makes sense if you plan on blowing the image or a section of the image up.Satellite cameras can still use all the resolution they can get.
