From the way it looks like it, 2.0 and 2.1 are the same now, only the features from 2.1 are now optional.My cheap 4K TV only has HDMI 2.0b ports which also does VRR (variable refresh rate) , ALLM
Better use DP anyway. Well, using HDMI 2.0 is the next best thing then. You certainly don't need 2.1 for 60 Hz, so you're fine. Your GPU is backwards compatible with HDMI 2.0, so yes, your existing monitor will work fine. You will really only need 2.1 for higher resolution+refresh rate monitors, i.e. 1440p @ 240Hz or 4K @ 120Hz.

If you plan to play games on your display at higher refresh rates, now or in the future, HDMI 2.1 is the display cable to use (unless you have DisplayPort as an option). Do I need HDMI 2.1, is a question you might ask when buying a new TV. The answer is, if you can, do it, as you'll find yourself trying to take advantage of it sooner or later.

1. [deleted] • 3 yr. ago. Short answer: HDMI 2.0 is perfectly fine, HDMI 2.1 won't become a necessity for at least 5-7 years. Long Answer: The main difference between HDMI 2.0 and 2.1 is the maximum refresh rate at 4K and 8K, on an HDMI 2.0 cable you can achieve 1440p 120hz, 4K 60hz, and 8K 30hz.
Therefore, lots of people wonder which HDMI ports to use for 4K Samsung TV. According to a source, I can say that one must use HDMI 1 port for getting 4K video quality at 60Hz refresh rate with HDR support. Other HDMI ports also support 4K contents but don’t have the full range. Now, the discussion doesn’t end there.
Yep. What a disgrace. The entire display industry should’ve moved to DisplayPort years ago. “HDMI 2.0 no longer exists… the new capabilities and features associated with HDMI 2.1 are optional”

HDMI has been the de-facto connector for monitors, TVs, and projectors. If you want to connect your laptop or PC to an external display, just run an HDMI cable and you're golden.
Your 4K Blu-ray player can’t even scratch the surface of the 18 Gbps bandwidth of HDMI 2.0, let alone the 48 Gbps of HDMI 2.1. Everything a 4K Blu-ray can offer — 4K resolution, high chroma HDMI ARC and eARC: the one-cable solution for TV audio, fully explained. By Simon Cohen June 17, 2023. If you’re unboxing a brand new 4K TV, AV receiver, or soundbar, you’ve likely noticed a The HDMI 2.1 standard is faster than HDMI 2.0, the current connection used by modern home entertainment devices. It nearly triples the bandwidth of HDMI 2.0, defining a maximum speed of 48Gbps Increased bandwidth is the most salient improvement HDMI 2.1 delivers. We’re talking a staggering 48 gigabits per second, compared to the 18Gbps that HDMI 2.0 can handle. That bandwidth bump
Despite their similarities, though, there are some very real reasons you might choose to use DisplayPort 1.4 or HDMI 2.1, so let’s take a look at the major differences between these two popular connection standards. From a pure bandwidth perspective, HDMI 2.1 offers far more. Where HDMI 2.1 offers a maximum bandwidth of 48 Gbps.

Only HDMI 2.0 or newer cables support 4K 60Hz. Although 4K was introduced with HDMI 1.4, it’s only limited to 30Hz. If you want to watch content at 60 FPS, you need a compatible HDMI 2.0 cable, TV, and receiver. 4K 120Hz only works on HDMI 2.1 compatible devices and cables. 4K TVs weren’t all that common before HDMI 2.0 was released in 2013.

You can use a PS5 with HDMI 2.0 and display up to 60 frames per second at 4K resolution. HDMI 2.1 is only required for games running 8K resolution at 60 frames per second, or 4K resolution at 120 frames per second. A PS5 console with an HDMI cable connected to the port. What I just said probably sounds like absolute nonsense to less experienced
