Like AMD's FreeSync or NVIDIA's G-SYNC, the HDMI group has created their own version of the VESA Adaptive Sync protocol, called HDMI Forum VRR. It's a VRR format that seems to only work with HDMI 2.1 sources, and the Xbox Series X currently supports it alongside its FreeSync VRR support. The PS5 should also receiveHDMI Forum VRR support in a future firmware update. Note that not all HDMI 2.1 TVs support HDMI Forum VRR, as is the case with the LG UN8500. All those extra pixels – six times that of standard 4K video – require greater bandwidth to send the information across. HDMI 2.1 cables are up to the task, with an upper limit of 48Gbps (Gigabits per second) rather than 18Gbps. As female HDMI connectors are usually recessed into the body of TVs, games consoles, projectors, computers, and monitors - and because they tend to be more susceptible to deforming under excessive strain than male connectors - they’re more widely sold as standalone replacement parts.

While certainly not sexy, a 48Gbps HDMI 2.1 cable is essential for getting the most out of a PS5, Xbox Series X or gaming PC (and, to a lesser extent, an Apple TV 4K). With a lesser cable, you likely won't get 4K/120Hz– and VRR might not work either. Or you might get a generally patchy performance. Of course, the PS5 and Xbox Series X each come with an HDMI 2.1 cable, but you might need a replacement or an extra one. Automotive Use HDMI Type E Connector "MX50/53 Series" Has Been Developed".

The only thing you need to do is connect your first monitor directly to the HDMI port. Then, use another cable that supports both your second monitor and PC. The 48 Gbit/s bandwidth provided by HDMI 2.1 is enough for 8K resolution at approximately 50 Hz, with 8 bpc RGB or Y′C BC R 4:4:4 color. To achieve even higher formats, HDMI 2.1 can use Display Stream Compression with a compression ratio of up to 3∶1. Using DSC, formats up to 8K ( 7680 × 4320) 120 Hz or 10K ( 10240 × 4320) 100 Hz at 8 bpc RGB/4:4:4 are possible. Using Y′C BC R with 4:2:2 or 4:2:0 chroma subsampling in combination with DSC can allow for even higher formats. [125]

HDMI 2.0a was released on April8, 2015, and added support for High Dynamic Range (HDR) video with static metadata. [120] The maximum limits for TMDS transmission are calculated using standard data rate calculations. [143] For FRL transmission, the limits are calculated using the capacity computation algorithm provided by the HDMI Specification. [144] :§6.5.6.2.1 All calculations assume uncompressed RGB video with CVT-RB v2 timing. Maximum limits may differ if compression (i.e. DSC) or Y′C BC R 4:2:0 chroma subsampling are used.

Basically, there are several techniques to display our content on dual or even multiple monitors. Large number of additions and clarifications for CEC commands. One addition is CEC command, allowing for volume control of an AV receiver. [5] :§CEC-1.3 As discussed above, there are now HDMI 2.1 TVs available from the likes of LG, Samsung, Sony, Vizio, Hisense, Panasonic and Philips. On January 28, 2008, In-Stat reported that shipments of HDMI were expected to exceed those of DVI in 2008, driven primarily by the consumer electronics market. [21] [31]Auto Low Latency Mode (ALLM)– When a display device supports the option to either optimize its pixel processing for best latency or best pixel processing, ALLM allows the current HDMI source device to automatically select, based on its better understanding of the nature of its own content, which mode the user would most likely prefer.
