What HDMI version do I need?
For streaming and Blu-ray (4K/60 Hz), HDMI 2.0 is sufficient. For gaming at 4K/120 Hz or using VRR on a PS5 or Xbox Series X, you need HDMI 2.1 — both the cable and the HDMI port on your TV must be 2.1.
HDMI version comparison
| HDMI version | Bandwidth | Max resolution | HDR | VRR / eARC |
|---|---|---|---|---|
| 1.4 | 10.2 Gbps | 4K / 30 Hz | No | No |
| 2.0 | 18 Gbps | 4K / 60 Hz | HDR10, Dolby Vision | No / ARC only |
| 2.1 | 48 Gbps | 4K / 120 Hz; 8K / 60 Hz | Full HDR suite | VRR + eARC |
When 2.0 is enough
- Streaming services (Netflix, Prime, Disney+) top out at 4K/60 Hz
- 4K Blu-ray players output 4K/60 Hz
- Cable and satellite boxes are typically 1080p or 4K/30 Hz
- Most current-gen streaming sticks (Fire TV, Chromecast) use HDMI 2.0
When you need 2.1
- PS5 or Xbox Series X at 4K/120 Hz (requires 2.1 port on TV and 2.1 cable)
- PC gaming monitor at 4K/120+ Hz
- Variable Refresh Rate (VRR) to eliminate screen tearing
- Enhanced Audio Return Channel (eARC) for lossless Dolby TrueHD / Atmos passthrough to soundbar
HDMI cable certification labels
The version of the cable is defined by bandwidth, not a version number on the box. Look for these labels:
- Premium High Speed — 18 Gbps; supports HDMI 2.0 features
- Ultra High Speed — 48 Gbps; supports HDMI 2.1 features
