This HDMI fragmentation is also why some of the latest HDMI 2.1 TVs don’t support VRR: it is not a given just because you have an HDMI 2.1 socket. It will be less of a headache by the end of Unlike the original HDMI ARC, which works with all HDMI cables, eARC does require new cables that have the higher bandwidth of the 2.1 spec. eARC will work with HDMI 2.0 cables as well, but they As above, there's no such thing as HDMI 2.1 cables. (Or HDMI 2.0 cables or any other number, HDMI cables don't have numbers) HDMI 2.1 is a hardware standard for TV's, AVR's etc. The cable you'd be looking for is an Ultra High-Speed Certified Cable, but they only exist at 3M just now AFAIK and they cost a fortune. About 6 months ago, I purchased a 4K TV with an HDMI 2.0 port and 120hz. I have googled HDMI 2.0 to HDMI 2.1 adapters, but only found HDMI 1.4 to HDMI 2.1 adapters. However, these adapters seem to be in development and the websites I found that sell them are off-brand (i.e. not at Best Buy, Wal-Mart etc.). 1463 posts · Joined 2001. #10 · Mar 14, 2022. eARC is great. ARC isn't. eARC is part of the feature set of hdmi 2.1, but can work on HDMI 2.0 (b) receivers. So while hdmi 2.1 might not be needed, i'd suggest eARC is. While up until HDMI 1.3 the saying “all HDMI cables are made equal” was more or less correct, since HDMI 1.4 and the advent of 4K the various data bandwidth of each cable makes a huge difference. To place things in perspective, HDMI 1.3 can pass 10.2Gbps (gigabits per second) and doesn’t support 4K at all. That version of HDMI is now A cable designed for HDMI 2.0 will work fine on an HDMI 1.4 connection, and vice versa. That does change with HDMI 2.1, as all the additional bandwidth needs a new generation of high-end cables to best support it. But they aren't mandatory. If you're wondering, do I need HDMI 2.1 cables, then the answer is yes, but not necessarily straight away. Kinda silly. Yes. Your monitor will need an HDMI 2.1 input and you'll need to use HDMI 2.1 cables in order to utilize 120hz for console systems at 4K. If your monitor is 1080p or 1440p with 120hz, you can get 120hz in those modes I believe with HDMI cables iirc. So it's my understanding if you want 4K @ 120hz, you'll need to have a monitor with Hdmi 2.0 is capable of 1440p@120hz and 4k@60hz with HDR at 4:2:2 chroma which Xbox supports. Those are the max targets of Series S so it doesn't need an Ultra High Speed HDMI cable. Series S also has a hdmi 2.1 port so if you want those resolutions with 4:4:4 chroma just go buy a $10 Ultra High Speed HDMI cable. 145. rG5Wh.
