Better Gaming with HDMI 2.1 using VRR, QMS, QFT, ALLM

Posted by Charbax – February 10, 2018

HDMI 2.1 Specification Supports a Range of Features for Enhanced Gaming:
- 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.

48Gbit/s HDMI 2.1 cable, up to 10K120

Posted by Charbax – February 10, 2018

HDMI 2.1 Specification Supports Ultra High Speed Bandwidth Up to 48Gbps enabling Higher resolutions and faster refresh rates including 8K60Hz and 4K120Hz and support for resolutions up to 10K120 compressed. The Ultra High Speed HDMI Cable supports 48Gbit/s bandwidth for uncompressed HDMI 2.1 feature support and has very low emissions of Electromagnetic interference (EMI).

Dynamic HDR with HDMI 2.1, Technicolor Advanced Dynamic HDR

Posted by Charbax – February 10, 2018

Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts. Here this interview is with Technicolor about their implementation of Dynamic HDR supported as part of the new HDMI 2.1 Spec.

eARC with HDMI 2.1, Enhanced Audio Return Channel at up to 40mbit/s

Posted by Charbax – February 10, 2018

eARC in HDMI 2.1 simplifies connectivity and supports the most advanced audio formats such as object-based audio, such as Dolby Atmos and DTS:X, highest audio quality, and ensures compatibility between audio devices and upcoming HDMI 2.1 products, enabling to deliver those formats via an eARC-enabled HDMI port on a future HDMI 2.1 TV. eARC also provides support for the TV’s over-the-air tuner, streaming apps received by the TV, and audio from HDMI sources connected to the TV.

A key advantage of eARC is that it enables a TV-centric living room or home theater configuration that can provide a more seamless experience. Today, an AV receiver—or a similar repeater device—is necessary to extract high quality audio from an HDMI link, while the video is processed and passed through to the TV. The user may have to switch inputs on both the TV and an audio device to find the source of their content, and content sourced within the TV and from TV inputs is frequently limited to stereo or, in the best case, one of a very small number of compressed formats.

With eARC, it will be possible to connect all sources through the TV and send audio to the sound system completely uncompromised. Furthermore, eARC will make possible a new breed of audio-only receivers that will yield greater value and ease-of-use by eliminating a video subsystem. So, in theory anyway, overall video and audio performance will improve with eARC.

HDMI alt mode USB Type-C in a UHD Blu-ray player

Posted by Charbax – September 26, 2017

HDMI Licensing Administrator shows 4K60 Premium Certified HDMI alt mode over USB Type-C Connector on a modified UHD Blu-ray player, by just re-routing the HDMI signal instead of going to an HDMI connector can transfer the same HDMI signal through the USB Type-C connector. For now devices like smartphones, tablets and PCs who want to be able to output HDMI signal over USB Type-C need to have a small chip to transfer the HDMI signal but later some SoCs might be adding this functionality directly onto the SoC.

Premium HDMI Cable Certification Program at IFA 2017

Posted by Charbax – September 26, 2017

HDMI Licensing Administrator shows some examples of the HDMI cables that get to be part of the Premium HDMI Cable Certification Program from such brands as Hama and Avinity brands which are popular in Europe, Rocketfish which is Best Buy's HDMI cable brand, blackweb and GE which are Walmart's HDMI cable brands and the affordable monoprice brand too.

Premium HDMI Cable Certification Program

Posted by Charbax – August 24, 2017

The Premium HDMI Cable Certification Program is the new program from the creators of HDMI technology that encompasses additional and enhanced cable testing as well as an authentication and verification program. Cables are tested to ensure they support the full 18Gbps bandwidth from the HDMI 2.0b specification plus an EMI test to ensure cables minimize interference with wireless signals. The program is designed to give end users confidence when purchasing new HDMI cables for their 4K/UltraHD products that may include features such as 4K@60Hz, BT.2020 and HDR. Participating HDMI Adopters can promote their ATC-tested High Speed HDMI Cables as Premium High Speed HDMI Cables or Premium High Speed HDMI Cables with Ethernet using a unique anti-counterfeiting authentication label on their products which can be checked and authenticated using the app on any smartphone. Also watch my video about the new HDMI 2.1 spec and my video about HDMI Alt Mode for USB Type-C.

HDMI Alt Mode for USB Type-C

Posted by Charbax – June 29, 2017

The HDMI Alt Mode for USB Type-C connector will allow HDMI-enabled source devices such as smartphones, tablets, laptops and camcorders to utilize a USB Type-C connector to directly connect to the Billions of HDMI-enabled displays (which is included with 100% of flat panel TVs), and deliver native HDMI signals over a simple cable without the need for protocol and connector adapters or dongles. HDMI Alt Mode will support the full range of HDMI 1.4b features such as 4K, surround, ARC, 3D, HDMI Ethernet Channel (HEC), Consumer Electronic Control (CEC), Deep Color, x.v.Color and content types, HDCP 2.2. HDMI Alt Mode follows all necessary Alt Mode USB Type-C specification requirements which auto-detects HDMI Alt Mode source devices and HDMI-enabled displays, requires no adapters to connect from an HDMI source to an HDMI display, source output is AC coupled for HDMI Clock and Data lanes and other.

HDMI 2.1, 4K120, 8K60 (up to 10K120 compressed), new 48Gbps cable, Dynamic HDR

Posted by Charbax – June 6, 2017

HDMI 2.1 supports 4K120 and 8K60 uncompressed over a new 48Gbps cable, even supporting up to 10K 120fps compressed. HDMI 2.1 also supports Dynamic HDR, eARC and Game Mode VVR. Dynamic HDR enables variable HDR on a scene-by-scene even frame-by-frame basis. eARC enables object-based 3D audio. Game Mode VRR features variable refresh rate, which enables a GPU to display the image at the moment it is rendered for more fluid and better detailed gameplay, reducing or eliminating lag, stutter, and frame tearing.
