Promate PrimeLink8K-300 HDMI 2.1 Cable 3M – 8K@60Hz

Promate PrimeLink8K-300 HDMI 2.1 Cable 3M – 8K@60Hz

If you’ve shopped around, you’ll notice every other Kenyan retailer runs the exact same Promate spec sheet for this cable. Here’s what actually matters when you’re buying one: does it carry a genuine certification, will it actually hit 48Gbps in real use, and will it work with what you already own? The PrimeLink8K-300 is Promate’s certified Ultra High-Speed HDMI cable — independently tested to the full HDMI 2.1 specification, not just labelled “8K” because the box says so. A lot of uncertified cables claim 8K support but cap out around 18–24Gbps in practice, which means dropped frames or no signal at all on real 8K/4K120 content.

Is This Cable Actually Different From a Cheaper One?

Cable Type	Bandwidth	Max Resolution	eARC	Dynamic HDR	Typical KE Price
Standard HDMI 2.0 cable	18 Gbps	4K@60Hz	No (ARC only)	No	KES 500–900
Uncertified “8K” cable	Often overstated	Claims 8K, frequently fails above 4K60	Inconsistent	Inconsistent	KES 600–1,500
PrimeLink8K-300 (this cable)	48 Gbps (certified)	8K@60Hz / 4K@120Hz	Yes	Yes	KES 2,200
Promate PrimeLink8K-500 (5M)	48 Gbps (certified)	8K@60Hz / 4K@120Hz	Yes	Yes	Higher (longer run)

 

Who Actually Needs This Cable

• PS5 / Xbox Series X owners running 4K@120Hz or VRR — standard HDMI 2.0 cables physically cannot carry this, regardless of what the console settings menu shows.
• Owners of newer Samsung, LG, Hisense, or Skyworth TVs with HDMI 2.1 ports — common on 2023+ mid-range and flagship models sold in Nairobi electronics shops; this cable unlocks those ports’ full spec instead of running them at HDMI 2.0 speeds.
• Home theatre setups using eARC for Dolby Atmos / DTS:X soundbars and AV receivers.
• Content creators and editors moving 4K/8K footage from a laptop to an external reference monitor.
• Office and boardroom presentations where a single reliable 3M cable beats hunting for adapters.

How Do I Know If I Actually Need 8K vs. Just 4K?

Most Kenyan households are running 4K TVs, not 8K — and that’s fine, because the PrimeLink8K-300 is fully backward compatible and will simply run at your device’s native resolution. The reason to buy the 48Gbps version even for a 4K setup is 4K@120Hz gaming (PS5/Xbox/PC) and VRR/ALLM support, which a standard HDMI 2.0 cable cannot carry no matter how it’s marketed. If you’re only ever doing 4K@60Hz with no console gaming, a standard cable works — but it won’t future-proof you for an 8K TV or a 120Hz gaming session.

Frequently Asked Questions

Is this the genuine Promate PrimeLink8K-300, or a clone?

This is a genuine, certified Promate unit sourced through official channels, not a generic “8K-labelled” cable. Promate’s HDMI 2.1 cables carry official Ultra High Speed HDMI certification, which uncertified cables sold under generic “8K 60Hz 48Gbps” listings typically don’t have — meaning they’re not guaranteed to hit the spec printed on the box.

Will this work with my PS5 or Xbox Series X for 4K@120Hz?

Yes. HDMI 2.1’s 48Gbps bandwidth is exactly what’s required for 4K@120Hz and VRR gaming on PS5 and Xbox Series X/S — a standard HDMI 2.0 cable will bottleneck this even if your console and TV both support it.

I have a 4K TV, not 8K — is this cable overkill?

No. It’s fully backward-compatible with 4K and HD displays, and the extra bandwidth still gets used for 4K@120Hz gaming, eARC audio, and Dynamic HDR — none of which a basic 18Gbps cable can carry.

What’s the difference between eARC and the older ARC?

ARC (older HDMI standard) caps out around 1Mbps and can’t carry full Dolby Atmos or DTS:X. eARC, supported here, handles up to 37Mbps — enough for uncompressed high-fidelity surround formats from your TV’s apps straight to a soundbar or AVR.

Does cable length affect signal quality at 8K/48Gbps?

Yes, more than with older HDMI standards — the higher the bandwidth, the more signal degrades over distance. 3M is within Promate’s certified passive-cable range for full 48Gbps performance; if you need a longer run (5M+), an active or fiber HDMI 2.1 cable is recommended instead of a longer passive one.

Is this cable compatible with older devices?

Yes — HDMI 2.1 is backward compatible with HDMI 2.0, 1.4, and earlier, so it works on older TVs, monitors, and consoles too, just without the 2.1-specific features like VRR or 4K@120Hz.
