  • HDMI 2.1 Final Specs Confirmed 10K Resolution Support “Enhanced Refresh Rate Features” & More

The much-anticipated HDMI 2.1 specification has been released by HDMI Forum, Inc. Dynamic HDR formats are also supported, with bandwidth capability upped to 48Gbps. The previous spec, HDMI 2.0, had a significantly lower bandwidth at 18 Gb/s. HDMI 2.1 also allows for "dynamic HDR (high dynamic range)", which features the same high range of contrast and brightness in a scene-by-scene or even frame-by-frame basis. It offers low electro-magnetic interference, which reduces interference with nearby wireless devices. It is backwards compatible and can be used with the existing installed base of HDMI devices.

If you're looking for more information, check out the HDMI Forum's Release Presentation.

Higher video resolutions support a range of high resolutions and faster refresh rates including 8K60Hz and 4K120Hz for immersive viewing and fast-action detail.

Up to 25000 bugs could be living in your Christmas tree
A lot of the farms that grew trees for the wholesale market to supply the retailers cut back on planting around 10 years ago. Procrastinators may win out too - plenty of Christmas tree farms drastically lower prices a few days before the 25th.

Refresh rates for 4K will top out at 120Hz, while 8K will peak at a still solid 60Hz.

It introduces some major improvements over the predecessor, HDMI 2.0, such as improved bandwidth speed of 48Gbps, up from 18Gbps seen in the predecessor. Don't worry if your TV does not support 10K (no TVs right now do) the new 2.1 standard of HDMI cables will be backwards compatible.

Additional features of the new standard includes eARC, which is designed for simplified connectivity and supports advanced audio formats, ensuring compatibility between audio devices and upcoming HDMI 2.1 products.

Hadiya, whose original name was Akhila Ashokan, had married Jahan after she met him on an Islamic matrimonial site. Saturday, before departing from Kochi , Hadiya had said that she wanted to go back and stay with her husband.

Another big novelty for HDMI is support for Dynamic HDR as well as the Variable Refresh Rate (VRR) technology, which should reduce lag, frame stutter, skipping and freezing as well as deal with that pesky frame tearing. There's also Quick Media Switching, which is helpful for movies and video because it eliminates the delay (often displayed as a black screen) before content appears on the screen. The new feature list also includes Quick Frame Transport, a reduced-latency mode for games, mixed reality, and karaoke.
