HDMI 2.1 and DisplayPort Cables: Certification, Length and Gaming – Buying Guide 2026

For 4K at high refresh rates, VRR and eARC, a random “HDMI cable” is often not enough. HDMI Licensing Administrator and HDMI.org define cable categories; for HDMI 2.1 bandwidths up to 48 Gbps, the official Ultra High Speed HDMI Cable is the class to look for. On a PC, DisplayPort 1.4 (HBR3) is often the better link — ideally with VESA certification. This guide covers certification, length and connectors, plus five models currently available on Amazon.de.

Transparency: We have not tested these cables ourselves. The basics come from HDMI.org / HDMI LA, VESA/DisplayPort.org and verified Amazon.de product pages (as of October 2026). We do not list prices because they change constantly.

HDMI 2.1 vs DisplayPort — quick view

PS5/Xbox and many TVs use HDMI. For gaming PCs with DisplayPort on the monitor, DP is usually preferable — high refresh without HDMI adapters. Monitor details: Gaming Monitor Buying Guide. Laptops often have HDMI and USB-C/DP — see Gaming Laptop and USB-C Hub.

What matters most

1. Official cable names, not marketing buzzwords

Per HDMI.org, the Ultra High Speed HDMI Cable belongs to the HDMI 2.1 world and targets configurations up to 48 Gbps. It is part of the Ultra HDMI Cable Certification Program: every length must be tested at an HDMI Forum Authorized Testing Center. Packaging should show the Certification Label with the official cable name and a QR code; the name should also appear on the jacket. “HDMI 2.1” or “8K” on the box alone is not a substitute for the label.

For DisplayPort, VESA defines certified cable classes; for DP 1.4/HBR3, DP8K-certified cables are the common reference for 8K@60 / 4K@120 in maker materials.

2. What bandwidth means for gaming

An Ultra High Speed HDMI cable can carry the high data rates that enable features such as uncompressed video up to 8K@60 or 4K@120, dynamic HDR, eARC, VRR and ALLM — if both source and display support them. The cable alone does not unlock features.

DisplayPort 1.4 with HBR3 provides up to 32.4 Gbps raw bandwidth per VESA (about 25.9 Gbps payload with 8b/10b). Many gaming monitors use that for 1440p/4K at high Hz; extreme modes may need DSC. UHBR/DP 2.x (DP40/DP80) needs matching devices and cables — for most 2026 setups, certified DP 1.4 is enough.

3. Keep length short; long runs only if certified

Passive copper gets harder at high frequencies as length grows. Desks often need only 1–2 m. For 3–5 m, buy certified Ultra High Speed lengths only (each length is certified separately). Longer runs may need certified active/optical HDMI cables — not covered in the product list below.

4. Connectors and shielding

• HDMI Type A for TV/console/monitor
• DisplayPort with latch — KabelDirekt and others advertise locking plugs
• Solid shielding (foil/braid) helps with EMI; Ultra High Speed cables are also tested for low EMI per HDMI.org

5. Check the ports on both ends

PS5 and Xbox Series X use HDMI 2.1 ports. Many portable monitors and laptops have HDMI 2.0 or 2.1 — the port spec decides, not only the cable. On a PC: GPU output and monitor input must both support DisplayPort 1.4 (or higher).

More sources than HDMI ports: a switch with a cable

When a PS5, an Xbox and a PC compete for one HDMI 2.1 input, an HDMI switch helps. Then every cable counts twice: the path to the display stays Ultra High Speed, and the runs to the switch should be short. FeinTech recommends HDMI cables of at most 1.5 m for 4K/120 on the SW211. What matters for bandwidth, power and ARC is covered in the HDMI switch buying guide.

Example: FeinTech SW211 with an integrated cable

According to FeinTech: HDMI 2.1 up to 48 Gbps, 4K/120 or 8K/60, VRR, ALLM and QFT, two inputs and one output (also usable in reverse), integrated HDMI cable of about 50 cm, powered by the source. No ARC/eARC. Fulfilled by Amazon, in stock (checked November 2026).

Matching TV: check the HDMI 2.1 ports

The best cable only helps if the TV input supports 4K@120 and VRR too. On many TVs, not every port does. What to look for in ports, VRR, ALLM and eARC is covered in the gaming TV buying guide.

Example model

Example TV with four HDMI 2.1 ports: LG OLED55C6ELB

Per LG, all four HDMI inputs support 4K@120Hz, VRR, ALLM, QMS and QFT; VRR up to 165Hz, eARC on HDMI 2. Sold and shipped by Amazon, in stock (checked October 2026).

Checklist before you buy

1. Which ports do source and display have — HDMI or DisplayPort?
2. Do you actually need 4K@120 / VRR / eARC — and can both devices do it?
3. Is the Ultra High Speed label (HDMI) or VESA claim (DP) on the packaging?
4. Keep length as short as possible — verify each certified length?
5. For TV + soundbar: eARC port and a matching HDMI cable?
6. On a PC: prefer DP cable over HDMI adapters when both ends have DP?

FAQ

Is a “High Speed” HDMI cable enough for the PS5?

For 4K@60 and many cases, often yes. For full HDMI 2.1 data rates (e.g. 4K@120 when TV and console support it), HDMI.org points to the Ultra High Speed HDMI Cable class with a certification label.

Do DisplayPort cables need certification too?

VESA-certified cables give more confidence at HBR3. Cheap uncertified cables can fail at high modes — use maker claims and Amazon’s return policy.

HDMI or DisplayPort on a gaming monitor?

If GPU and monitor both have DisplayPort, DP is usually first choice for high refresh. Use HDMI when the monitor only has HDMI 2.1 or you connect a console/TV.

Does a pricier cable improve picture quality?

Within the same certified class: not in a measurable “prettier” way. Either the link sustains the required rate — or you get dropouts / no signal.

Do I need DP 2.0 / UHBR?

Only if GPU and monitor actually use UHBR rates. For typical 1440p/4K gaming in 2026, certified DP 1.4 is often enough.
