Meaning instead of 40Gbps both directions, you do 80Gbps in one direction (which for video is really what you want).
(If it was DP 2.0 alt-mode, the way they do it is by taking the 40Gbps of USB-C that is full duplex (so 40 Gbps each direction) and flipping the return lanes to transmit lanes. HDMI 2.1 comes in standard HDMI, Mini HDMI, and Micro HDMI, and you can get Ultra High-Speed HDMI cables (supporting HDMI 2.1 bandwidth and features) as well as Ultra High-Speed HDMI with Ethernet cables, which provide the same functionality but can also support an Ethernet connection. I half suspect they are saying 48Gbps but know anyone using it won't need that for the resolution they claim, and can say they only support up to 8k30 and 4k120 which is inside the DP 1.4 bandwidth range. I feel it usually takes longer though, and with everything going on in the chip market. Then again they were aiming for 2021 products. So it could do the resolutions it claims (8k30 and 4k120)ĭP 2.0 as an Alt mode (77Gbps) was released like a year ago, so I doubt its implemented in anything. That would be the only way to get the bandwidth for the resolutions it mentions.ĭP 1.4 (most common DP Alt Mode and also in Thunderbolt 3/4) is 32.4Gbps It reads "supports" but I suspect that means requires. This adapter supports USB-C devices with DP Alt Mode support and Thunderbolt 3 port / Thunderbolt 4 ports
