HDMI 2.1 Supported TVs! Which one to buy in 2023?


Wait! We intentionally skipped the article which one to buy in 2019. We told you in 2018 that HDMI 2.1 is going to be the next big thing, and if you want to get future-proofed, you should wait. Xbox one X, Series X, PS4 pro, PS5 , google stadia, whatever you’ve it.

Now its the time 2020. 2019 was lame half baked. This year, Every major manufacturer has HDMI 2.1 going into its new TVs (Sony is still in confusion hehe). 

We are skipping the technical jargon here. What’s matters are, Variable Refresh Rate (VRR), Enhanced Audio Return Channel (eARC), Quick Media Switching,Auto Low Latency Mode (ALLM), Dynamic HDR and Quick Frame Transport.

What is HDMI 2.1? Why it matters?

VRR, ALLM, and Quick Frame Transport all promise the best gaming experience for console gamers. These features are of high-end gaming monitors. Dynamic HDR and eARC improve picture quality and the audio experience significantly, while Quick Media Switching enhances the user experience. Instantaneous – no more black screen while making the switch between, say, a video game, and a streaming app. Too fast! These are not gimmick. These are real.

HDMI 2.0 vs 2.1 – What Can HDMI 2.1 Do That HDMI 2.0 Cannot? 

Let’s face it; technology powers the New Age, and without it, we would be nothing. New technology drives modernity, and every day new advancements are being made by computer technicians who are hard at work, determined to create new versions of cables, TVs, and other devices. New versions that are much more powerful, better, stronger.

There are many versions of HDMI connections, and version 2.1 is the latest one. Entering worldwide markets this year, HDMI 2.1 is the future of cables. To help you understand, we’ve compiled a list of details specs comparing 2020’s HDMI 2.1 with 2.0, so you can get the best out of your upgraded cable experience!


Naturally, because HDMI 2.1 is a newer version of the same product, it comes with improved resolution. Not only does it allow for higher resolutions, but it also encourages the use of higher frame rates. Where HDMI 2.0b offered up to 4K resolution with a 60Hz frame rate, version 2.1 is set to host 4K at 1120Hz, 8K at 60Hz, and even up to an outstanding 10K resolution for heavy-duty commercial requirements.

The frame rate jump is excellent news for gamers because it will allow them to experience a whole new world of gaming like never before. With an improvement in frame rate, games will appear more lifelike and be able to support better graphics.


In HDMI 2.0b, we saw the handy Audio Return Channel (ARC) feature, which allows audio to travel forward and back through an HDMI cable plugged between one’s TV and A/V receiver. However, the limitations in the HMDI 2.0 bandwidth led to distortions in audio quality, especially for more tedious formats. 

Luckily, HDMI 2.1 offers Enhanced Audio Return Channel (eARC), which will encourage the transmission of uncompromised audio in its original full resolution.

Dynamic HDR

HDR significantly improves picture quality when compared with older systems like 1080. Dynamic HDR, as the name suggests, provides even greater picture quality thanks to improvements in certain features, like more brightness steps and stronger visual representation of details in dark, shadowy footage.

Variable Refresh Rate

HDMI 2.1 has the brilliant ability to allow TVs to load new gaming frames at any time, even if the actual frame rate is highly variable. The framerate may jump and fall as it wishes, depending on the game coding. But problems occur because most TVs are not made for such framerate jumps. However, thanks to the new HMDI 2.1 cable, such jumps can be accommodated, and any problems or fragmentation can be overcome.

Quick Frame Transport

This is a system in HDMI cables that reduces the time it takes for video frames to pass from the initial source device, like a PC or gaming console, to a visual display device, like a TV or VR headset. Gamers will again benefit from this and will experience significantly less lagging, especially in fast, action-packed first-person shooter games. VR devices, too, will experience a substantial positive shift in speed and framerate.

Quick Media Switching.

Sometimes, when you switch on a screen or try to change input sources, an annoying black screen shows up. Well, there’s great news to follow, because now that’s going away permanently!

Auto Low Latency Mode (ALLM)

Gamers rejoice; this fantastic feature allows an ALLM to inform your TV or display system when a signal is coming from a gaming console or PC. In turn, the display system automatically shuts off any alternative picture processing system, so you don’t need to switch to Game Mode. Your TV will just do it for you.

Lip Sync Issues

Syncing your TV video to your receiver or soundbar’s audio can be an absolute hassle sometimes. Because of audio processes faster than video, often there is a system lag, and the two don’t sync up. This can be a real problem and ruins the entire experience. Sometimes, a reverse effect also goes through, which is equally disturbing. 

The great thing about HDMI 2.1 is that it fixes this issue by enabling TVs to communicate in real-time with sound systems, guaranteeing perfect synchronization.

HDMI 2.1 Cables

HDMI 2.1 cables are a massive upgrade from the previous versions, like 2.0a and 2.0b. Here are the key points:

· Faster speed

· Better framerate

· Flawless synchronization

· Less lagging

· Improved resolution

HDMI 2.1 Backward Compatibility

Yes! HMDI 2.1 does have the backward capability with older technology. They can work well together because while HDMI 2.1 does have better capabilities, it’s still just a buildup from the previous versions. 

How Does HDMI 2.1 Matter in New TVs Compare to Old TVs with HDMI 2.0?

Whether or not you need a new cable for your TV depends on some things. If your new TV is made for solely HDMI 2.1 cables, naturally you will need a new cable. Also, if you want to use a device with a higher resolution that’s only supported by HDMI 2.1, again, you will need a new cable.

New TVs are generally made with new features that HDMI 2.0 cannot support. They have improved qualities like higher minimum framerate support and improved resolution threshold. 

Compared to HDMI 2.1, HDMI 2.0 has lesser features, which are only compatible with older TVs. The gist is that older TVs can use both HDMI 2.0 and 2.1, but newer TVs cannot use 2.0, only 2.1.


The world of HDMI is growing, booming, and improving at an insane rate. The new 2.1 cables may not become popular immediately, but there is undoubtedly a positive forecast prediction for it. For now, though, you can continue using your 2.0 cable, or even upgrade to 2.1. The choice is yours..
