Product description
If you’re trying to squeeze the most out of a modern TV or gaming setup, the cable matters more than most people expect. The Ubluker Certified Ultra High Speed HDMI cable is positioned as a “future-friendly” HDMI lead, with a certified label on the outer packaging and support for a wide set of HDMI features.
That said, cables still aren’t magic: if your devices and ports don’t support the features you’re aiming for, you won’t get the headline numbers just by swapping the lead. Still, on paper, this one ticks enough boxes to be a sensible upgrade for high-refresh gaming and HDR viewing.
The essentials
This is an HDMI-to-HDMI cable from Ubluker, marketed as “Certified Ultra High Speed HDMI”. The listing highlights an official HDMI certification label on the front of the outer packaging, and full compliance with the HDMI Forum requirements (as specified in the description).
The key idea is bandwidth and compatibility with modern video and audio formats. The cable is described with:
- Up to 48Gbps
- Low EMI
- Support for features such as 0.01ms, CEC, eARC/ARC, ALLM, VRR, QMS, and QFT
- HDR10+ and “Dynamic HDR”
- HDCP 2.2 and HDCP 2.3
If you want a single HDMI cable that can cover gaming consoles, TVs, projectors, monitors and sound systems without constantly second-guessing feature support, this is the type of cable that tends to fit the bill.
What you’ll notice day to day
Where this cable is most likely to make a practical difference is in setups that actually use modern HDMI features: high refresh rate gaming, HDR streaming, and passing audio back to a soundbar or AV receiver.
For example, imagine you’ve got a PS5 (or an Xbox) connected to a TV, and you also care about sound going through eARC to your speaker system. With HDMI eARC support flagged in the listing, this cable is aimed at that kind of “one cable for picture and sound” arrangement.
It’s also geared towards displays and sources that support HDR10+ and other HDR modes mentioned in the description, which matters if your TV can’t do those formats over a lower-capability cable.
Where it shines (and where it might fall short)
On the “worth considering” side, this cable is clearly specified for high data-rate use. The listing includes multiple refresh-rate and resolution combinations (including 4K 240Hz and 8K 60Hz) and also points to support for deep colour (12bit) and relevant HDMI behaviours for gaming and fast switching (like VRR and ALLM).
But here’s the limitation to keep in mind: the impressive headline modes only apply when the source device, display, and settings all line up. A cable can be certified, but it can’t force a TV to run at 4K 240Hz if the TV/port doesn’t support it.
Also, the cable length is given as 4M. That’s usually fine for many living room layouts, but if your routing needs a longer run—or if it has to cross power-heavy cables—distance and environment can become a factor. The listing doesn’t provide installation guidance, so it’s worth planning the route before you commit.

Buying guidance: who it’s for
It’s a good fit if you’ve got a modern TV or monitor setup where you care about:
- High refresh rate gaming (the listing explicitly mentions 4K 240Hz)
- HDR10+ and “Dynamic HDR” playback
- Sending audio over eARC to a soundbar or AV receiver
- Using multiple devices such as a games console, PC/laptop, projector or media players without swapping cables each time
It may not suit you if your system is mainly older equipment that doesn’t support the advanced HDMI features referenced in the listing. In that case, paying for certification and bandwidth you can’t use can feel a bit pointless.
What to check before you buy
Before you order, it’s worth checking three practical things:
1) Whether your TV/monitor actually supports the mode you want (for example, the “4K 240Hz” type of setup referenced in the listing). 2) Whether your audio chain supports eARC/ARC, if you want sound through a soundbar or receiver. 3) Whether 4M is the right length for your room layout—especially if you’re routing around entertainment units.
Final verdict
It’s worth considering if you want a certified Ultra High Speed HDMI lead that’s aimed at modern, feature-heavy viewing and gaming, including HDR10+ and eARC. If your devices support those features, this cable’s spec and certification positioning make a lot of sense.
You may want to skip it if you’re using older hardware that won’t take advantage of higher refresh rates, deeper colour, or advanced HDR and audio modes. And remember: the best results depend on device compatibility and the settings you select, not just the cable.
Mini FAQ
Does this cable support HDR10+?
The listing states support for HDR10+ and “Dynamic HDR”.
Is eARC supported?
Yes, eARC (and ARC) are specifically mentioned in the description.
What does “48Gbps” mean in practice?
In simple terms, it’s the cable’s bandwidth capability, which helps it handle high-bit-rate video/audio combinations that compatible TVs and sources can output.
Is 4M likely to be enough?
4M can cover many typical home setups, but you should measure your route first to avoid stretching or awkward routing.
Will it automatically give 4K 240Hz?
Not automatically. The listing includes support for 4K 240Hz, but the source, display, and settings all need to support it.
