Yes, the quality and specifications of the HDMI cable can matter for 4K resolution, especially for longer cable lengths or higher refresh rates. While older HDMI cables may be capable of transmitting a 4K signal, they may not support the full bandwidth required for high-resolution content or advanced features like HDR (High Dynamic Range) or higher refresh rates.
For optimal performance with 4K content, it's recommended to use an HDMI cable that meets the HDMI 2.0 or later specification. These cables are designed to support the higher bandwidth requirements of 4K video at 60Hz refresh rates and can handle features like HDR and wide color gamuts. Additionally, if you're planning to use HDMI cables for longer distances, consider using cables that are certified for longer runs and have built-in signal amplification or shielding to prevent signal degradation.
In summary, while an older HDMI cable may work for basic 4K video playback, using a newer HDMI cable that meets the HDMI 2.0 or later specification can ensure the best performance and compatibility with advanced 4K content and features.
