UGREEN Certified HDMI 2.1 Cable (48Gbps, 8K/4K up to 240Hz) with eARC, Dolby Atmos & Dolby Vision – 5M
Product description
The essentials
If you’re trying to get the most out of a modern games console or a high-spec monitor, HDMI 2.1 cables matter more than people think. This UGREEN Certified HDMI 2.1 lead is built around a stated 48Gbps bandwidth, with support for higher resolutions and refresh rates, plus features such as VRR and ALLM. It also includes eARC support, which is where it earns its keep if you’re running audio through a soundbar or AV setup.
On paper, it ticks a lot of the right boxes for gaming and home entertainment: smoother motion via the higher refresh-rate modes listed, lower input lag with ALLM, and less tearing with VRR. It’s also positioned as a work-friendly cable thanks to its slim, portable design and a braided jacket intended to resist wear and tear.
Worth noting: a cable can’t fix a device that doesn’t support the modes you’re aiming for. So the real win here is getting a cable that can carry the signals your TV/monitor and source are capable of.
Where it shines (in everyday use)
The most practical reason to choose a HDMI 2.1 cable like this is consistency when you switch between modes—gaming, movies, and general desktop use. For example, if you connect a PS5 or Xbox Series X/S to a compatible TV/monitor, you can use the higher refresh rate options mentioned in the listing (including 4K 120Hz and even 4K up to 240Hz, depending on what your display supports).
For audio, eARC is the feature you’ll notice if you’ve previously had to compromise on sound. With eARC in the chain between TV and an eARC-compatible soundbar (or similar audio device), the cable is intended to support higher-quality, uncompressed surround sound formats listed in the description, including Dolby Atmos and DTS:X.
And if you’re watching HDR content, the cable’s support for dynamic HDR is relevant for setups that use formats such as Dolby Vision and HDR10+ (as referenced in the listing). This is one of those “it’s good when it’s good” features—worth it only if your TV and source actually use those HDR modes.
Key takeaways for gaming and low-lag setups
This cable is explicitly aimed at gaming and work use. The listing calls out:
- VRR (variable refresh rate) to help reduce screen tearing.
- ALLM (auto low latency mode) to help minimise lag when you start playing.
- Dynamic HDR support linked to the 4K 120Hz mention.
If your display supports these features, this cable is one of the easier ways to avoid being the weak link. If it doesn’t, the cable can still be useful, but you won’t see the full benefit—some modes in the listing will simply never be used.

What to watch before you buy
This cable supports a wide spread of high-end video modes, but you should sanity-check your display and your source first. Two common “it doesn’t behave as expected” scenarios are:
- Your TV/monitor supports HDMI 2.1, but only some ports (or only some settings) will enable the higher refresh rates.
- You’re aiming for a specific HDR or surround format, but your TV and audio device chain doesn’t fully support it—especially for Dolby Vision / HDR10+ and certain Atmos/DTS modes.
It’s also a long lead (5M). That’s convenient for cable routing, but if you’re very sensitive to signal quality in a long run, placement and avoiding tight bends is still worth keeping in mind.
Compatibility and connections
The listing claims broad “plug and play” compatibility across a range of HDMI device types—consoles (PS5/PS4/PS3, Xbox Series X/S/One/360), laptops, PC, capture card/GPU setups, TV boxes, projectors, AV receivers, and eARC soundbars. It also references connection to standard HDMI ports including HDMI 2.1/2.0/1.4.
In real terms, that means it should be a sensible replacement or upgrade cable for a typical living-room gaming setup or a desk-based monitor workflow—especially where you want to carry both video and audio through the same HDMI connection to a TV and then out to sound.
Pros
- A high listed bandwidth (48Gbps) with support for high refresh-rate modes.
- Gaming-focused features called out in the description: VRR and ALLM.
- eARC support for soundbar/AV setups, with multi-format surround support listed.
- Slim, thin cable design with a braided jacket and metal-bodied plug elements mentioned.
It may not suit you if…
- You only need basic 1080p/60Hz viewing and don’t care about gaming features or HDR—this may be more than you need.
- Your TV/monitor and audio chain don’t support the specific HDMI 2.1-related modes you’re looking for, because the cable can’t enable features your equipment doesn’t offer.
Should you buy it?
Buy this UGREEN HDMI 2.1 cable if you’ve got a PS5/PS4 or Xbox Series X/S setup and a display that supports higher refresh rates and/or HDR modes, and you want one cable that can carry both video and (through eARC) higher-quality surround audio to a compatible soundbar. It also makes sense if you’re after a portable, tidier cable that’s built for day-to-day connections.
Skip it if your equipment is mostly older HDMI (or you’re not trying to run advanced gaming/HDR or eARC audio). In that case you may be paying for headroom you’ll never use.
Mini FAQ
Does this cable support 8K and 4K at high refresh rates?
The listing says it supports up to 8K@60Hz and multiple 4K refresh-rate options, including 4K@240Hz and 4K@120Hz. Whether you can actually use those modes depends on your TV/monitor settings and what it supports.
What does eARC add here?
eARC is intended to simplify an audio path between your TV and an eARC-compatible soundbar or audio device, and the description lists support for surround audio formats including Dolby Atmos.
Will VRR and ALLM work on any TV?
VRR and ALLM support depends on the TV/monitor and the source device both supporting those features. The cable is designed to help carry them when available.
Is 5M too long for gaming setups?
5M can be handy for routing around desks and consoles, but it’s still worth managing the cable sensibly (avoid harsh bends) and ensuring your display is configured correctly for the modes you want.
What’s the main limitation to keep in mind?
A cable can’t make unsupported video/audio modes appear. If your display or soundbar chain doesn’t support the relevant HDMI 2.1 features, you won’t see the full benefit.
