And that means you want 48gbps bandwidth as opposed to 18gbps, to do what exactly? To do better than to achieve a 4K picture at 60 FPS or an 8K picture at 30 FPS? I know that HDMI 2.1, on the other hand, promises 4K resolution at 120 FPS, 8K resolution at 60 FPS, and a ceiling that will ultimately support 10k - whoopee! And precisely where do we see that content? Don'tget me wrong but HDMI 2.0b does what I need - to split the video and sound and all HD sound. Unfortunately eARC will not pass the DTS HD formats due to licencing, which convinced me not to wait for this inferior option to get off my new media player, HDR10+ video and all HD sound.
