HDMI 2.0a, for example, added support for high dynamic range, or HDR, which allows for a more vivid picture with a greater range and depth of colors.The LG OLED65E9 TV is equipped with HDMI 2.1 controllers. As well as providing a maximum bandwidth of 48 Gbps compatible with video resolutions and refresh rates that are a lot higher than the HDMI 2.0 standard (up to 8K 50/60 FPS and 4K 100/120 FPS), the HDMI 2.1 standard also offers two new features for gamers: VRR and ALLM. Both the cable and HDMI 2.1 standards will be backward compatible with their previous models. For everything over 8K at 60Hz, HDMI 2.1 uses DSC (Display Stream Compression), which is an effective form of data rate compression without any impact on the image quality. It increases latency, but the added delay is imperceptible (below 1ms). While TVs with HDMI 2.1 ports are pretty much guaranteed to have eARC support, several manufacturers have added eARC support on their devices with HDMI 2.0 as well. You can check the HDMI connectors on the back of your device, and an eARC-compatible device will typically have eARC mentioned next to a connector.
HDMI 2.1 also supports the latest color spaces, such as BT.2020, with 10 or more bits per color and higher frame rates in uncompressed 8K resolution video at 60 frames (4:2:0) per second and 4K video at 120 frames (4:4:4) per second. Resolutions that use Display Stream Compression (DSC) technology, like 8K at 120 Hz and 10K at 120 Hz, are only
Also Read: Is HDMI Backwards Compatible? HDMI is Backwards Compatible BUT NOT Forward Compatible. So the key concept to understand here is that the HDMI interface and cable versions are backward compatible. Hence, you can: Use an HDMI 2.1 (Ultra High-Speed Cable) with a 1.4 port; Use an HDMI 2.1 cable (Ultra High-Speed Cable) with a 2.0 port . 341 992 766 390 943 813 446 124
