This article covers the Monoprice 4K Slim Certified Premium High Speed HDMI Cable 6ft (18Gbps, black), including the things worth knowing before you buy.
Overview
This is a Premium High Speed certified HDMI cable with 18Gbps of bandwidth, tested by an HDMI Authorized Test Center, supporting 3840x2160 (4K) video. The short version: it is more than enough for 4K/60Hz with HDR, and it is not the cable for 4K/120Hz or 8K.
The 1.8m (6ft) length suits TV cabinets and desktop runs.
The slim construction bends easily behind wall-mounted TVs and inside tight racks. On Amazon.co.jp it held 4.7 out of 5 stars across 611 reviews (94% positive) as of May 2026.
Compatibility Guide
Both ends use standard HDMI Type A connectors, so it works with essentially any HDMI-equipped TV, monitor, projector, console, or PC. It follows HDMI 2.0-class 18Gbps signaling and supports 4K/60Hz, 32 audio channels, and a 1536kHz sampling rate.
The key question is what 18Gbps does and does not cover:
| Use case | Enough at 18Gbps? |
|---|---|
| 1080p/60Hz and 1080p/120Hz | Easily |
| 4K/60Hz with HDR | Yes — the intended use |
| 1440p around 144Hz | Generally yes, depending on device settings |
| 4K/120Hz, 8K/60Hz, 48Gbps eARC setups | No — you need an Ultra High Speed cable |
If you plan to use the 4K/120Hz modes on a PS5 or Xbox Series X, or a high-refresh HDMI 2.1 monitor, buy a 48Gbps Ultra High Speed certified cable instead.
For Blu-ray players, streaming sticks, 4K/60Hz console gaming, or a laptop feeding a meeting-room display, 18Gbps is simply not the bottleneck.
With an AV receiver in the chain, the receiver's HDMI ports set the ceiling, not the cable. If a receiver is HDMI 2.0-era, a 48Gbps cable will not unlock 4K/120Hz.
When the picture drops or flickers, check the oldest device in the chain before blaming the cable.
The 1.8m length also helps stability.
High-bandwidth HDMI signals attenuate with distance, and passive runs beyond 5m more often struggle at 4K/60Hz. Over short distances like this one, that risk largely disappears.
Product Info
Key specs: HDMI Type A connectors on both ends, 1.8m (6ft) length, 18Gbps maximum data rate, 3840x2160 (4K) supported resolution, Premium High Speed HDMI Cable certification from an HDMI Authorized Test Center, and Monoprice's Lifetime Warranty that covers all of its cables.
On pricing: as captured on 27 August 2026, Amazon.co.jp listed it at ¥3,104, while the Amazon US listing showed ¥3,105 as captured on 29 May 2026.
An eBay US listing showed $4.25 as captured on 8 July 2026.
All are point-in-time figures that move with sales, exchange rates, and stock, so check the product page for the current price. The package contains the cable only.
Reviews stood at 611 with 4.7 out of 5 stars (94% positive) as of May 2026.
Cable reviews tend to be confirmations rather than critiques, but holding 4.7 across 600-plus reviews is reasonable evidence that defect and unit-to-unit variation risk is low.

How It Compares
Monoprice HDMI cables have confusingly similar names. Three axes matter:
- Certified or not — the same "4K Slim 18Gbps" description exists both with and without Premium High Speed certification. Certified cables have passed Authorized Test Center testing, which makes troubleshooting a failed 4K/60Hz link much easier. For a few hundred yen, it is worth it.
- Length — the family includes 3ft, 6ft, and 15ft options. Longer runs are sometimes Active (with signal amplification) and directional, so orientation matters there. This 6ft cable is passive, so either end can face the source.
- Bandwidth — 18Gbps and 48Gbps 8K Ultra High Speed cables are different products. If a 4K/120Hz display is in your future, buying the 48Gbps cable now is cheaper overall.
Against rival brands, Monoprice's appeal is not nylon braiding or gold-plated marketing but certification plus a lifetime warranty at a low price. Choose a braided competitor if you want a premium feel; choose this if you want function and coverage.
Installation Tips
Slim cables are flexible but the connector strain relief is still the weak point. Behind a wall-mounted TV where the cable hangs straight down, leave a small service loop so the connector is not carrying weight, and avoid cinching zip ties tightly.
If the picture drops out, troubleshoot in this order: reseat the cable, try a different HDMI port, verify the TV or monitor's enhanced HDMI input mode is enabled (the name varies by brand), then test with another cable. That third step is a very common cause of 4K/60Hz failing, and no cable swap will fix it.
Before You Buy
1. No 4K/120Hz, no 8K. This is the core trade-off.
18Gbps is HDMI 2.0-era bandwidth; 4K/120Hz and 8K/60Hz require a 48Gbps Ultra High Speed certified cable.
"4K support" here means 4K/60Hz. Anyone buying this for 120Hz gaming will regret it.
2. Cables do not improve picture quality. HDMI is digital: within spec, a pricier cable will not change color or sharpness.
Certification buys reliability of the link, not image quality. When bandwidth is insufficient the failure mode is a black or flickering screen, not visible noise.
3. The product names are easy to confuse. "4K Slim High Speed," "4K Slim Certified Premium High Speed," and "8K Ultra High Speed" differ by only a couple of words.
Confirm the length (6ft), bandwidth (18Gbps), and certification wording on the listing before ordering.
4. Do not take listing metadata at face value. Amazon listings sometimes carry manufacturer names, model numbers, or specs that do not match the physical product.
Nothing looked inconsistent for ASIN B074FFM8NH and the Monoprice branding at the time of writing, but verify the product with the images and title yourself. Cables in particular bundle multiple variations on one page, so double-check which variation is selected.
5. The lifetime warranty is only as useful as your purchase path. Claiming it depends on the seller and region.
For a cable at this price, treat it as insurance against DOA units rather than a long-term service plan.
6. Prices change. Every figure here is point-in-time.
Cables in this bracket swing by several hundred yen with sales and coupons, so confirm the current price before ordering.
Best Use Cases
- Home theater setups running 4K/60Hz with HDR that want a certified, known-good cable
- Short 1.8m runs from a Blu-ray player or streaming stick to a TV
- PS5 or Xbox Series X owners happy to stay at 4K/60Hz and skip 120Hz modes
- Gaming PCs feeding a 4K/60Hz or 1440p monitor
- Wall-mounted TVs and cramped racks where thick cables will not route cleanly
- Offices and meeting rooms stocking spares
It is not for you if 4K/120Hz or 8K is on the roadmap, if you need runs longer than about 5m, or if cable aesthetics matter to you. The first two are hard spec limits; the last reflects a deliberately practical design.
FAQ
Q. Will it work with a PS5? A.
Yes, up to 4K/60Hz. It cannot carry the PS5's 4K/120Hz output; use a 48Gbps Ultra High Speed cable for that.
Q. Can I connect it to an 8K TV?
A. You will get a picture, but not at 8K. 18Gbps tops out at 4K/60Hz.
Q. Does eARC work? A.
eARC depends on your TV and receiver support and settings. This cable is listed at 18Gbps with 32-channel audio, but check the required bandwidth and your devices' specs on the product pages before buying for an eARC-centric setup.
Q. How does it differ from the non-"Certified" version? A.
Only the certification through an HDMI Authorized Test Center. You may see no practical difference, but certification lets you rule the cable out when troubleshooting.
Q. Can I extend it if 1.8m is too short? A.
HDMI couplers tend to degrade the signal and are not recommended at 4K/60Hz. Buy a single cable of the right length, such as the 15ft version, instead.
Q. What does it cost? A.
Amazon.co.jp listed it at ¥3,104 as captured on 27 August 2026.
Prices move often, so check the listing for the current figure.
