How to Choose the Right HDMI Cable

Stop buying overpriced cables. Learn the difference between HDMI versions, bandwidth requirements, and certifications for your display setup.

1. Identify your resolution and refresh rate. Determine the native resolution and maximum refresh rate of your source device and display. 4K at 60Hz requires different bandwidth than 4K at 120Hz or 8K content. Higher resolutions and frame rates demand higher data throughput.
2. Match the cable classification to the bandwidth. Purchase 'Ultra High Speed' HDMI cables for 4K/120Hz or 8K support, as they handle 48Gbps. For 4K/60Hz, 'Premium High Speed' cables are sufficient at 18Gbps. Avoid legacy 'Standard' cables for modern displays.
3. Check for eARC support. If you are connecting a soundbar or receiver, ensure your cable supports eARC (Enhanced Audio Return Channel). All 'Ultra High Speed' cables support eARC by default. This enables high-bitrate audio formats like Dolby Atmos and DTS:X.
4. Determine the required cable length. Keep the cable length as short as possible to prevent signal degradation. For distances over 5 meters, use active optical HDMI cables to maintain signal stability. Avoid coiling excess cable tightly behind the display to prevent interference.
5. Verify physical build quality. Select cables with robust connector housing and shielding. Ensure the connector fits snugly into the HDMI ports without excessive wiggle room. Avoid cables with overly rigid jackets if you need to route them through tight cable management channels.
