When purchasing an HDMI cable, here are the key factors to consider:

HDMI Version: Cables come in different versions, each supporting varying resolutions and refresh rates. For example:

• HDMI 1.4 supports up to 1080p and 4K at 30Hz.
• HDMI 2.0 supports 4K at 60Hz.
• HDMI 2.1 supports 4K at 120Hz and 8K at 60Hz. Check your device specifications to match the cable to your desired resolution and refresh rate.

Cable Length: Longer cables can sometimes experience signal degradation. For lengths under 10 feet, standard HDMI cables should work well, but for longer distances (20+ feet), consider high-quality, active HDMI cables designed to boost the signal.

Bandwidth and Speed Rating:

• Standard Speed: Works for resolutions up to 1080i.
• High Speed: Handles 1080p, 4K at 30Hz, and HDR.
• Premium High Speed: Designed for 4K at 60Hz with HDR.
• Ultra High Speed: Suitable for HDMI 2.1 capabilities (8K, high refresh rates).

Certification: Look for cables labeled “Certified” or with a certification sticker. This guarantees the cable meets HDMI standards and performance claims.

Build Quality: For durability, consider cables with reinforced connectors, gold-plated contacts, and braided or thick outer jackets, especially if they’ll be plugged in and out often.

Compatibility with Your Devices: Some devices have specific HDMI requirements, so always check if they need a particular HDMI version or special features like Ethernet or ARC/eARC (for advanced audio setup).

With these factors in mind, you’ll be better equipped to choose an HDMI cable that matches your needs and ensures reliable performance for your TCL devices!
