a b Even for a compressed audio codec that a given HDMI device cannot transport, the source device may be able to decode the audio codec and transmit the audio as uncompressed LPCM. In addition, the data is transmitted more efficiently by using a 16b/18b encoding scheme, which uses a larger percentage of the bandwidth for data rather than DC balancing compared to the TMDS scheme used by previous versions (88. Uncompressed 10 bpc (30 bit/px) color depth with RGB or Y′C BC R 4:4:4 color format and CVT-R2 timing are used to calculate these data rates.

This will reduce consumer confusion as DisplayPort Alternate Mode is the primary video protocol of choice over USB-C. Features specific to HDMI, such as remote-control and audio transport, are not available in devices that use legacy DVI-D signalling. You might want something higher-specced or more robust for longer stretches, not to mention something with more bandwidth if you’re purchasing a new mid-range or high-end telly, but for older kit and budget HDMI 2. p. III Each subsequent version of the specification uses the same kind of cable but increases the bandwidth or capabilities of what can be transmitted over the cable.can transport Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio bitstreams in compressed form. Otherwise, there are a few cables with different swivelling or 90-degree connectors that might make it easier to use them with a screen that’s in a constrained space or mounted on a wall. Auto Low Latency Mode: This ensures that games and other fast-paced content will be shown with minimal lag or delay.

e., it contains a USB-PD node) that serves to tunnel the DDC and CEC from the source over the Configuration Channel to the node in the cable, these USB-PD messages are received and relayed to the HDMI sink as regenerated DDC (SCL and SDA signals), or CEC signals. It’s the same story if you’re planning to make use of advanced AV and gaming features like Variable Refresh Rate (VRR), eARC lossless audio connectivity and Dynamic HDR at the highest resolutions or frame rates. A braided cable design means it's reasonably rugged too so if your cable has to sit at an awkward angle or gets pulled around a lot, it'll withstand any damage for longer than a regular cable.

As you can see, there are many different HDMI cable configurations and each has its own advantages and disadvantages that users need to be aware of when purchasing one for use with their video devices. HDMI cables with Ethernet differ in that three of the separate conductors instead form an additional shielded twisted pair (with the CEC/DDC ground as a shield).

If you want to make sure that you are getting the most out of your 4K TV, you need to use an HDMI 2.
