HDMI Forum, Inc. today announced the release of Version 2.1 of the HDMI Specification which is now available to all HDMI 2.0 adopters. This latest HDMI Specification supports a range of higher video resolutions and refresh rates including 8K60 and 4K120, and resolutions up to 10K. Dynamic HDR formats are also supported, and bandwidth capability is increased up to 48Gbps. Supporting the 48Gbps bandwidth is the new Ultra High Speed HDMI Cable. The cable ensures high- bandwidth dependent features are delivered including uncompressed 8K video with HDR. It features exceptionally low EMI (electro-magnetic interference) which reduces interference with nearby wireless devices. The cable is backwards compatible and can be used with the existing installed base of HDMI devices.
Version 2.1 of the HDMI Specification is backward compatible with earlier versions of the specification, and was developed by the HDMI Forum's Technical Working Group whose members represent some of the world's leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components.
"The HDMI Forum's mission is to develop specifications meeting market needs, growing demands for higher performance, and to enable future product opportunities," said Robert Blanchard of Sony Electronics, president of the HDMI Forum.
HDMI Specification 2.1 Features Include:- Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and smooth fast-action detail. Resolutions up to 10K are also supported for commercial AV, and industrial and specialty usages.
- Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts-on a scene-by-scene or even a frame-by- frame basis.
- The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.
- eARC simplifies connectivity, provides greater ease of use, and supports the most advanced audio formats and highest audio quality. It ensures full compatibility between audio devices and upcoming HDMI 2.1 products.
- Enhanced refresh rate features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include:
- Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
- Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
- Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
- Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.
The HDMI 2.1 Compliance Test Specification (CTS) will be published in stages during Q1-Q3 2018, and HDMI adopters will be notified when it is available.
The HDMI Forum Reaches Out to Grow Global Membership
The HDMI Forum is an open trade association that guides the future direction of HDMI technology and develops new versions of the HDMI Specification. The HDMI Forum currently has a membership of 92 companies, and is actively inviting more companies to apply for membership and help shape the future of HDMI technology. There is also a focus to encourage more companies to participate as the global presence of HDMI-enabled products and solutions continues to grow.

The fact is the reason they went digital was more efficient use of bandwidth channels, nothing more.
They even keep a list to name and shame companies that are no longer licensees of the HDMI standard - www.hdmi.org/learningcenter/adopters_terminated.aspx :kookoo:

Now, 4K TVs are all over the place but content is not. ATSC is to NTSC as ATSC 3.0 is to ATSC 1.0. It will introduce HEVC, 4K, and HDR standards making them as benign as MPEG2, 720p, and 1080i are today. HDMI 2.0 was needed to transmit that signal. HDMI 2.1? First it was black and white TV, then it was color, then it was DTV, then it was HDTV, now we're getting to 4K UHD, and HDMI 2.1 exists solely to begin the push to 8K UHD. Not only does everyone have to buy new TVs to support 8K UHD, broadcasters have to buy new cameras, recording, editing, and transmission equipment, and people have to buy new receivers so their content isn't downscaled. We're talking billions of dollars easily, and repeatable about every decade or less.
But we are way off topic now.
The fact that the mandate seems to have coincided with other significant technical improvements in tv's, monitors, GPU's etc. is just more icing on the cake for us :)
[/LEFT] And a huge boon to their bottom line. ATSC 1.0 is going to be phased out too sometime after ATSC 3.0 rolls out. Reason: ATSC 1.0 tuners don't know what to do with an ATSC 3.0 signal. Nope, they go hand in hand. A "TV" is a TV because it has an NTSC/ATSC/PAL tuner in it. HDMI was practically invented to handle ATSC/PAL signals uncompressed with audio.
HDMI 2.0 was invented to handle 4K UHD BluRay. HDMI 2.1 is for 8K UHD.
Of course it's possible. The argument you are driving that the analog to digital conversion was primarily to drive upgrades (and furthermore, that no other standard would do) is insanely offtopic.
The problem with DTV is that it's an all or nothing proposition. In most cases people don't have an antenna big enough (approximately a foot of antenna length per 10 miles of distance to the broadcast tower) to handle the signal from the distance they're receiving it or they're not amplifying it enough to compensate for the number of connected devices. I get 95%+ reception here 24/7 and I'm 40-50 miles from the towers.
A lot of people buy dinky 3' circular antennas from Wal-Mart and expect it to magically work. If you aren't living in the cities where the broadcast towers are, mileage will vary greatly.
Oh right these idiots haven't even made a 5K@144Hz display yet, let alone a decent one with REAL HDR...
To think the OLED 4K HDR screen on my phone is probably nicer than ANY monitor you can buy right now for gaming under $5000 lol.
8K60, 4K120, Dynamic HDR etc etc
Shows picture of $3 HDMI cable from China o_O
