HDMI 2.0 is not long, the standard was introduced in 2014 and offered for the support of the high 4K image resolution. Barely three years later now comes with HDMI 2.1, the successor and puts once again on top. The HDMI Forum has introduced the specifications for the connection standard.
The classic 4K resolution (3840 x 2160 pixels) can be transferred using a favorite HDMI cable that can handle both audio and video transmission. However, a new HDMI 2.1 cable that will most likely replace the old one in the future; it can transmit up to 10K, which is an incredibly powerful 10240 x 4320 pixels. The new prototypes of HDMI 2.1 cables deliver an audio-visual transfer of everything that even the existing HDMI cables can handle, especially the 4K resolution and HDR graphics range. Joy makes the new standard of the HDMI connector and the players who can use the 120 Hz flame rate, or the QFT function, that is the limitation of the delay between the connection.
HDMI 2.1 is able to plug into any of today’s classic HDMI jacks of all devices, so there will not be a new connector that would not be ready for a lot of customers. HDMI 2.1 is now a kind of messenger of the future that came to tell us that although it does not look like, the era of 8K and 10K televisions will come soon and we should be well prepared.
HDMI 2.1: The new features and benefits
On paper HDMI brings some interesting innovations and advantages. Here are the most important new features summarized in overview.
- The higher bandwidth of up to 48 Gbps enables high resolutions and faster refresh rates. 4K (120 Hz), 8K (60 Hz) and 10K (120 Hz) are possible.
- HDMI 2.1 also supports Dynamic High Dynamic Range (HDR) transmission for better black-and-white contrasts in the picture. The new technology reproduces differences in brightness even better than the old standard, which so far only transmits the metadata statically.
- In addition, Dynamic HDR provides HDR information for each image (frame) compared to Static HDR and supports up to 16 bits per color channel – allowing film producers to set and get the ideal depth, detail, image brightness, and contrast levels for individual scenes Access to a wider color spectrum than before.
- Also renewed was the Audio Return Channel (ARC). With HDMI 2.1, it gets the addition Enhanced (eARC) and is intended to automatically detect object-based audio formats as well as provide enhanced control of the audio signal.
- Particularly interesting for gamers is the new VRR mode: The image signal in the cable is optimized for delay-free operation. By variable adjustment (frame dropping) of the refresh rate, the annoying tearing and stuttering should be prevented.
- The new high-performance console Xbox One is said to be one of the first devices to support the standard.
