![]() ![]() That said, the bitrate, at least, allows the theoretical 4K 120Hz 4:2:2 over existing HDMI cables, given some minor future spec tweaks (2.0a or 2.1 league). I guess that’d be theoretically HDMI 2.0a or 2.1 as a revision to allow 4K 120Hz without raising clock rate. (2) Alternatively, the use of more efficient packet-based compression may prove sufficient (eliminating 8b/10b when transcivers on both ends support it), when combined with higher-quality HDMI cable. (1) 15.9 Mbps could easily fit in 14.6 Mbps with a little bit of compression (even 4:4:4 lossless compression may actually be possible for common material/content, and decimation to 4:2:2 / 4:1:1 only for torture test cases such as compressing heavy-noise patterns) which could be invented in the future, now that HDMI 2.0 is packet based and can theoretically transmit any kind of data, including new image formats not yet invented. Due to the subdivision of HDMI certification standards, HDMI 2.1 is divided into TMDS (the bandwidth is equivalent to the original HDMI 2.0 and FRL protocols). However, since HDMI 2.0 is a packet based protocol that can technically transmit any kind of raw data, there are technical solutions in two directions: There is 8b/10b overhead that limits the raw data rate to 14.6 Mbps. ![]() Preview of NVIDIA G-SYNC, Part #2 (Input Lag).Preview of NVIDIA G-SYNC, Part #1 (Fluidity).The bandwidth is still the same as HDMI 2. The data packet was updated to carry the HDR metadata. This bandwidth allows for support of 4K video resolutions at a higher frame rates with more detailed. The only thing that changed in HDMI 2.0a is the data being transmitted in the packets. HDMI 2.0 even allows two different video streams to be viewed on one screen. The new standard gained Dolby Atmos surround sound technology and Auro 3D Audio for higher audio fidelity. You won't be able to do HDR anyway with a 1.4 ported. Maximum bandwidth in the HDMI 2.0 specs is 18Gbps. Also known as HDMI UHD, 2.0 supports 4K resolution at 50 to 60HZ frame rates with a maximum bandwidth of 18 Gbps. If you aren't using HDR, you should keep deep color disabled. That explains why your Pro, which uses a 2.0 port, works correctly. Which means you won't be able to use RGB 444.
