HDMI (High-Definition Multimedia Interface) is the world’s most ubiquitous audio-video interface standard. HDMI 2.1 is the current cutting-edge version, offering up to 48 Gbps bandwidth for 8K@60Hz and 4K@120Hz (up to 144Hz for PCs) with features like VRR, ALLM, and eARC. HDMI 2.0 remains the most common standard, supporting 4K@60Hz at 18 Gbps, while HDMI 1.4 is largely obsolete, limited to 4K@30Hz at 10.2 Gbps.
⚠️ STATUS DISCLAIMER
HDMI 2.2 ANNOUNCED (January 2025)
The HDMI 2.2 specification was officially released in January 2025, doubling maximum bandwidth to 96 Gbps and enabling uncompressed 4K@240Hz, 8K@60Hz with full 4:4:4 chroma, 12K@120Hz, and 16K@60Hz.
However, full 96 Gbps consumer products are not expected to hit the market until 2027 as chip makers are only now beginning to sample the new FRL2 silicon. The first HDMI 2.2-certified devices may reach the market before the end of 2026, but they will likely not support the full 96 Gbps specification. Ultra96 cables are expected to arrive in Q3 2026.
For 2026 buyers: HDMI 2.1 (48 Gbps) remains the most sensible choice for future-proofing your setup.

- ⚠️ First HDMI 2.2-certified devices expected by end of 2026, but they may not support the full 96 Gbps specification
- ⚠️ Full 96 Gbps consumer products expected 2027
Cable Type: Ultra96 HDMI® Cable – certified for up to 96 Gbps, part of the Ultra HDMI Cable Certification Program
💡 Pro Tip: The Ultra96 HDMI Cable and Ultra High Speed HDMI Cable are both part of the Ultra HDMI Cable Certification Program—a mandatory certification program ensuring that only high-quality, tested, certified, and compliant cables enter the market. Both cable types must be tested and certified to ensure low EMI characteristics, reducing interference risks with wireless networks, streaming players, Bluetooth devices, and mobile phones.
🔌 HDMI Cable Types & Certification
Understanding cable certification is more important than the version number on the box. Here are the five main cable types you’ll encounter:
| Cable Type | Bandwidth | Supports | Certification Label |
|---|---|---|---|
| Standard HDMI® | Up to 1080i | Basic HD content | Standard HDMI Logo |
| High Speed HDMI® | 10.2 Gbps | 1080p, 4K@30Hz, 3D, Deep Color | High Speed HDMI Logo |
| Premium High Speed HDMI® | 18 Gbps | 4K@60Hz, HDR, BT.2020 | Premium HDMI Certification Label with QR code |
| Ultra High Speed HDMI® | 48 Gbps | 8K@60Hz, 4K@120Hz, eARC, VRR, ALLM | Ultra High Speed HDMI Certification Label with QR code |
| Ultra96 HDMI® | 96 Gbps | 8K@60Hz full chroma, 4K@240Hz, 16K@60Hz | Ultra96 Certification Label with QR code |
⚠️ CRITICAL: As of mid-2025, the most sensible HDMI cable to purchase is the Ultra High Speed HDMI cable. It’s future-proof, backward-compatible, and you won’t really save money by going with older cables.
How to Spot Certified Cables
Look for the official certification label on the packaging:
- The certification logo must be displayed on the package
- Scan the QR code with your phone to verify the certificate was issued to that specific cable and length
- The cable jacket must display the official cable name
Price ≠ Quality – A $5 certified cable performs identically to a $50 “premium” cable as long as both meet the same certification standard.
Anti-Counterfeit Measures: The HDMI Forum has implemented an extensive certification program, including anti-counterfeit measures, to ensure consumers receive genuine, high-performance cables.
🛠️ How to Choose the Right HDMI Cable for Your Setup
Step 1: Identify Your Devices’ HDMI Ports
| Your Device | HDMI Version | Cable Needed |
|---|---|---|
| PS5 / Xbox Series X | HDMI 2.1 | Ultra High Speed HDMI |
| PS4 Pro / Xbox One X | HDMI 2.0 | Premium High Speed HDMI |
| PS4 / Xbox One / Switch | HDMI 1.4 | High Speed HDMI |
| 4K TV (2020+) | HDMI 2.1 or 2.0 | Ultra High Speed or Premium High Speed |
| 4K TV (pre-2020) | HDMI 2.0 | Premium High Speed HDMI |
| 8K TV | HDMI 2.1 | Ultra High Speed HDMI |
| RTX 30/40-series GPU | HDMI 2.1 | Ultra High Speed HDMI |
| GTX 10/20-series GPU | HDMI 2.0 | Premium High Speed HDMI |
Step 2: Check Your TV’s HDMI Port Labels
⚠️ Common Gotcha: Many TVs have multiple HDMI ports, but only one supports HDMI 2.1 features. Look for ports labeled:
- “eARC” – usually the HDMI 2.1 port
- “4K@120Hz” – HDMI 2.1 port
- “VRR” or “Game” – HDMI 2.1 port
For more help choosing the right display, check our best smart TV and Android TV guide.
Step 3: Calculate Your Bandwidth Needs
| Content Type | Bandwidth Required | HDMI Version Needed |
|---|---|---|
| 1080p @ 60Hz | ~3 Gbps | HDMI 1.4 |
| 4K @ 30Hz | ~8 Gbps | HDMI 1.4 |
| 4K @ 60Hz (8-bit) | ~12 Gbps | HDMI 2.0 |
| 4K @ 60Hz (10-bit HDR) | ~16 Gbps | HDMI 2.0 |
| 4K @ 120Hz (10-bit HDR) | ~32 Gbps | HDMI 2.1 |
| 8K @ 60Hz | ~48 Gbps | HDMI 2.1 |
Step 4: Consider Cable Length
- Up to 16 feet (5m): Ultra High Speed HDMI cables are typically certified for full 48 Gbps bandwidth at this length. Standard copper cables work well.
- Up to 25 feet (7.6m): Premium High Speed HDMI cables (18 Gbps) can work at this length. Some certified Ultra High Speed cables may also work at this length with active technology.
- Beyond 25 feet: Consider active HDMI cables or fiber optic HDMI cables to prevent signal degradation.
💡 Pro Tip: For Ultra High Speed HDMI cables (48 Gbps), certified lengths typically max out at 16 feet (5m) for full bandwidth. Beyond that, consider active or fiber optic cables.
Step 5: Verify Device Specifications, Not Just Labels
⚠️ Critical: The HDMI 2.1 label alone doesn’t guarantee performance. A device can legally wear an “HDMI 2.1” badge while supporting just one 2.1 feature and only 18 Gbps of bandwidth. Before buying for a high-bandwidth setup, confirm the device explicitly states 48 Gbps FRL support—not just “HDMI 2.1”.

❓ Frequently Asked Questions
Can I use an HDMI 2.1 cable with an HDMI 2.0 device?
✅ Yes. HDMI is fully backward-compatible. An Ultra High Speed HDMI cable (HDMI 2.1) will work perfectly with HDMI 2.0, 1.4, and older devices. However, performance will be limited to the lowest version in the chain.
Do I need HDMI 2.1 for 4K at 60Hz?
❌ No. HDMI 2.0 supports 4K@60Hz just fine. HDMI 2.1 is only needed for 4K@120Hz (or 144Hz on PC), 8K, or gaming features like VRR and ALLM.
What’s the difference between ARC and eARC?
ARC (Audio Return Channel) – introduced with HDMI 1.4 – allows TV to send audio back to a soundbar or AVR through the same HDMI cable. However, it has limited bandwidth (~1 Mbps) and supports only compressed audio formats like Dolby Digital.
eARC (Enhanced Audio Return Channel) – introduced with HDMI 2.1 – offers significantly higher bandwidth (~37 Mbps) and supports uncompressed, lossless audio formats like Dolby TrueHD and DTS:X, including Dolby Atmos. eARC is backward-compatible with ARC, but limited by ARC’s reduced bandwidth.
Do I need to buy expensive HDMI cables?
❌ No. Price does not determine performance. As long as the cable is properly certified (Premium High Speed or Ultra High Speed), a $5 cable performs identically to a $50 cable. Look for the certification label and QR code.
What HDMI version do I need for PS5 / Xbox Series X?
HDMI 2.1 is required to unlock the full capabilities of PS5 and Xbox Series X – 4K@120Hz, VRR, and ALLM. While these consoles will work with HDMI 2.0 (at 4K@60Hz), you’ll miss out on the key next-gen gaming features.
Is there an HDMI 2.2? When is it coming?
✅ Yes. HDMI 2.2 was announced at CES 2025 with 96 Gbps bandwidth. Ultra96 cables are expected in late 2026, with full 96 Gbps consumer products (TVs, AV receivers, GPUs) expected in 2027. For 2026 buyers, HDMI 2.1 remains the most sensible choice.
What’s the maximum length for an HDMI cable?
Standard passive Ultra High Speed HDMI cables (48 Gbps) work reliably up to about 16 feet (5 meters) for full bandwidth. Premium High Speed HDMI cables (18 Gbps) work up to about 25 feet (7.6 meters). For longer distances, you’ll need active HDMI cables or fiber optic HDMI cables that boost or convert the signal.
Does HDMI version affect picture quality?
✅ Yes and no. HDMI itself doesn’t “improve” picture quality – it simply provides the bandwidth needed for higher resolutions, refresh rates, and HDR formats. A higher HDMI version enables more data to pass through, allowing for better picture quality if your content and display support it. For more on visual quality, see our Full HD vs UHD 4K guide.
What is HDCP and why does it matter?
HDCP (High-bandwidth Digital Content Protection) is a copy-protection standard required for playing protected content like 4K Blu-rays and streaming services. HDMI 2.0 typically supports HDCP 2.2, while HDMI 2.1 supports HDCP 2.3. If your devices don’t support the same HDCP version, you may get a “No Signal” error or reduced resolution.
Can I use a longer HDMI cable for 4K@120Hz?
⚠️ Yes, but with caution. 4K@120Hz requires the full 48 Gbps bandwidth of HDMI 2.1. For runs over 10-15 feet, signal degradation becomes a risk. For longer runs, use a certified Ultra High Speed active cable or fiber optic HDMI cable.
What is Source-Based Tone Mapping (SBTM)?
SBTM is a feature introduced in HDMI 2.1a that allows the source device (e.g., a game console, PC, or streaming box) to assist the display with HDR tone mapping. This ensures a more consistent HDR experience across different devices, particularly when using external streaming devices connected via HDMI.
What is the Latency Indication Protocol (LIP)?
LIP is a new protocol introduced in HDMI 2.2 that “enhances audio video synchronization enables source devices to determine latency adjustments and to mitigate differences in audio and video to achieve improved audio/video synchronization”. It’s particularly important for “complex setups involving multiple devices such as AV receivers or soundbars”.
