How to pick an HDMI cable — decide by version (1.4 / 2.0 / 2.1) and use case

2026 update: ported from the old VuePress blog. The original draft assumed HDMI 2.0a as the ceiling, but HDMI 2.1 has gone mainstream for 4K120Hz / 8K / VRR, so the body has been rewritten end to end. Re-check the affiliate links against the current line-up.

“I want to hook a TV up to a game console.” “I need a second one for my PC monitor.” “It’s supposed to be 4K, but it doesn’t look 4K.” The reasons people stall on buying an HDMI cable are usually one of these.

Prices run from a few hundred yen to several thousand, and the cables all look more or less the same. The difference lives in two things printed in small type on the box: the version and the connector shape. This piece focuses on those two and aims to give you the shape of “the HDMI cable you should buy right now.”

The short answer — version, length, connector shape

Short version: picking an HDMI cable is not hard. A version that matches your use case, a length that is just long enough, and a connector shape that matches your gear — settle those three in order and you are done.

The shortest path, by use case:

1. Up to Full HD (1080p) — HDMI 1.4 is enough
2. 4K60Hz / HDR — HDMI 2.0 (Premium High Speed)
3. 4K120Hz / 8K / VRR (game consoles, latest GPUs) — HDMI 2.1 (Ultra High Speed)

For length, treat 1–3 m as the desk-side baseline and pick something a little longer than your actual run. For the connector, confirm “Type A (standard) / Mini / Micro” on both ends of the connection. Do those things and failure is rare.

What an HDMI version is — a bundle of bandwidth and features

What an HDMI version is

The number that marks a generation of the HDMI cable and connector spec. Each generation fixes a maximum bandwidth (Gbps), which in turn fixes the maximum resolution, refresh rate, and feature set (HDR, VRR, etc.) it supports. Newer cables are backward compatible with older features, but not the other way around — older cables cannot deliver newer features.

Miss this point and you get “the TV is 4K but the picture isn’t 4K” or “the game won’t push 120Hz.” When the cable can’t carry the bandwidth, the device automatically falls back to a lower signal.

The headline specs for each version look like this.

HDMI 1.4 — Full HD / up to 4K30Hz

Defined in 2009. Maximum bandwidth around 10.2 Gbps, with Full HD (1920×1080) at 60Hz and 4K (3840×2160) at 30Hz as the practical ceiling.

3D video and the Ethernet channel showed up in this generation. Today it sits as the floor for Full HD TVs and older monitors.

HDMI 2.0 — the mainstream for 4K60Hz / HDR

Defined in 2013. Maximum bandwidth 18 Gbps, supporting 4K60Hz and HDR10.

As of 2026, pairing a typical 4K TV or 4K monitor with mainstream gear, this is the safest baseline. Cables labeled Premium High Speed fall in this band.

If you actually want HDR to work, pick HDMI 2.0a or later. The difference between 2.0 and 2.0a is HDR metadata support, and the shortcut is to look for “HDR” called out on the box.

HDMI 2.1 — 4K120Hz / 8K / VRR

Defined in 2017. Maximum bandwidth jumps to 48 Gbps, with support for 4K120Hz, 8K60Hz, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM).

For 4K120Hz on a PlayStation 5, an Xbox Series X / S, or a current GPU, the cable has to be this generation or the bandwidth won’t hold up. These are sold as Ultra High Speed HDMI cables.

Some products call themselves HDMI 2.1 without actually clearing 48 Gbps, so when you buy, the safe move is to look for the “Ultra High Speed HDMI Cable” certification label.

Picking by use case — five patterns

Short version: the answer is set by what you are plugging into what. Drop your situation into one of the cases below.

TV + recorder (Full HD) — HDMI 1.4

For recording and playing back Full HD terrestrial broadcasts, HDMI 1.4 is plenty. A cheap basic-grade cable is fine.

4K TV + Blu-ray or streaming stick — HDMI 2.0

The content is mostly 4K60Hz / HDR. Pick a Premium High Speed certified cable. Anything sold at an electronics store under the “4K compatible” label is usually in this class.

PC + 4K monitor (creative work) — HDMI 2.0

For photo work, video editing, and design, 4K60Hz is enough. Use HDMI 2.0 as the baseline.

If the monitor has DisplayPort input, DisplayPort is often a generation ahead on bandwidth. If you aren’t tied to HDMI, it’s worth considering.

Game consoles (PS5 / Xbox Series X) — HDMI 2.1

If you want 4K120Hz or VRR working, HDMI 2.1 is required. The PS5 ships with an HDMI 2.1 cable in the box, so match that grade when you buy a second one.

Laptop + projector (occasional use) — HDMI 1.4 is fine

For projecting in a meeting room or on a trip, resolutions often drop to WUXGA or so. Length tends to need 3 m or more, so cable quality (shielding, conductor) moves the needle more than the generation does.

Comparison — HDMI 1.4 / 2.0 / 2.1

Max resolution, refresh rate, and headline use case in one table.

Length — pick “actual run + a little slack”

Short version: too short and it won’t reach; too long and it sags and gets in the way. The practical sweet spot is the measured run plus 0.5–1 m of slack.

Permanent install — 2–3 m

Wiring that runs behind a desk or down a wall is always longer than it looks. If your desk-side run measures 1.5 m, pick 2–3 m of cable.

Temporary use — 1–2 m

Plugging a laptop straight into a monitor puts the two devices close together. 1–2 m is enough.

Anything past 5 m needs care

HDMI works at long runs on paper, but 4K60Hz / HDR signals start dropping out around the 5 m mark. For long runs, look at optical fiber HDMI cables (Active Optical Cable, AOC).

Connector shape — confirm both ends

Short version: HDMI connectors come in three shapes — Type A (standard) / Mini HDMI (Type C) / Micro HDMI (Type D). Before you buy, check the connector shape on both ends of the link.

Home gear is almost always Type A, but Mini / Micro show up in these cases:

• Mirrorless cameras / camcorders — usually Mini or Micro
• Small laptops and 2-in-1s — Mini HDMI sometimes
• Action cameras — typically Micro HDMI

There’s also more gear that uses DisplayPort or USB Type-C (DP Alt Mode) instead of HDMI. A laptop with USB-C as the only video out won’t connect with an HDMI cable directly — you’ll need a USB-C to HDMI adapter.

FAQ

Q. If I buy an HDMI 2.1 cable, will my old gear get upgraded? A. No. HDMI only delivers a generation’s features when both endpoints and the cable support it. Plug a 2.1 cable into an older TV and the TV is still the ceiling.

Q. How do I tell Premium High Speed apart from Ultra High Speed? A. By the certification label on the packaging. “Premium High Speed HDMI Cable” corresponds to HDMI 2.0 / 2.0a, and “Ultra High Speed HDMI Cable” corresponds to HDMI 2.1. A bare “4K compatible” tag without a label is no guarantee of bandwidth.

Q. What’s the difference between a 1,000-yen cable and a 5,000-yen one? A. Mostly conductor material, shielding thickness, and connector build. For Full HD or 4K60Hz, a certified cheap cable is fine, and the 5,000-yen difference only really shows up in long runs, 4K120Hz, 8K, or pro gear.

Q. Does the cable itself change input lag? A. Almost never. Video input lag is dominated by what the TV or monitor is doing internally, and a cable doesn’t usually add to it. For gaming, picking an HDMI 2.1 device with ALLM / VRR support matters more.

Picks by use case

The picks below were chosen at the time of writing, with 2026 equivalents in the same band. Confirm the current generation at the time of purchase.

4K60Hz / HDR — HDMI 2.0 Premium High Speed

For the everyday case of plugging a home 4K TV into a PC or game console, a certified Premium High Speed cable is the first pick. Around 2 m is enough.

4K120Hz / 8K / VRR — HDMI 2.1 Ultra High Speed

If you want 120Hz out of a PS5, Xbox Series X, or current GPU, pick an Ultra High Speed certified cable.

Long runs past 5 m — Optical Fiber HDMI (AOC)

Good for ceiling-mounted projectors in meeting rooms, or layouts where the TV and the AV rack are far apart. They cost more than copper at the same length, but they carry 4K60Hz / HDR cleanly.

Wrapping up

Because HDMI cables look almost identical, just keeping version, length, and connector shape in mind collapses the decision to something simple.

Full HD: 1.4. 4K60Hz / HDR: 2.0. 4K120Hz, 8K, or VRR: 2.1. Length is the measured run plus 0.5–1 m, and confirm the connector on both ends. Stick to that and you avoid the “I bought it but it doesn’t deliver the picture quality” trap.

If you’re unsure, the shortcut is to check the maximum resolution and refresh rate of the gear you already own first. A cable is a tool that lets the gear hit its limit — it cannot push past what the gear itself can do.
