Best HDMI Cable Prices

Up to 50 ft fine for HDMI 2.0. HDMI 2.1 loses signal over 15 ft. Longer cables = thicker jacket needed.

Gold plating is marketing. Digital signal doesn't care. Certified cables by bandwidth spec matter. Brand matters for durability.

Yes, if you want 4K 120Hz output. The PS5 and Xbox Series X both output 4K 120Hz via HDMI 2.1, but a standard HDMI 2.0 cable is physically identical and may or may not carry the 48Gbps bandwidth required. Use a cable labeled 'Ultra High Speed HDMI' (the official HDMI 2.1 certification designation) to guarantee support. Most consoles ship with a basic cable — swapping it for a certified Ultra High Speed cable costs $10–15.

For 4K 60Hz projection: a standard High Speed HDMI 2.0 cable (18Gbps) is sufficient. For 4K with HDR: use a Premium High Speed HDMI cable (also 18Gbps but tested for HDR bandwidth). For 4K 120Hz on a laser projector: you need an Ultra High Speed HDMI 2.1 cable (48Gbps). Cable length matters — keep runs under 15 feet for 2.1; use an active optical cable for longer distances.

ARC (Audio Return Channel) carries compressed audio (Dolby Digital 5.1, DTS) from your TV back to a soundbar or AV receiver over a single HDMI cable — no separate optical cable needed. eARC (enhanced ARC) supports uncompressed Dolby TrueHD and Atmos at full bandwidth. If you have a Dolby Atmos soundbar or AV receiver, use eARC — both the TV and the soundbar must support it. Connect via HDMI 2.1 cable to an eARC-labeled port on both devices.
