Bought a PS5 or Xbox Series X to play at 4K@120Hz — and the games look juddery or drop to 4K@60Hz no matter what? The cable is the bottleneck on most setups. Standard High-Speed HDMI 1.4 tops out at 10.2 Gbps; 4K@120Hz needs the full 48 Gbps that only HDMI 2.1 provides. This Certified Ultra High-Speed HDMI 2.1 cable carries the official HDMI Forum certification (every certified cable is individually tested) and supports the full 48 Gbps bandwidth for 8K@60Hz, 4K@120Hz, dynamic HDR, VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and eARC. Built with high-purity tinned copper conductors, triple shielding, gold-plated connectors, and a flexible PVC jacket. Bi-directional — either end works as source or display. Compatible with PS5, Xbox Series X/S, RTX 30/40 series GPUs, Apple TV 4K, 8K and 4K@120Hz TVs, gaming monitors, AV receivers, and any HDMI 2.1 device. Best for: 4K@120Hz gaming, 8K home theater, eARC soundbars, and VRR-enabled displays. Not for: in-wall installation (no CL2 jacket). RoHS compliant.

PS5 and Xbox Series X output 4K at 120Hz, but standard HDMI 1.4 cables top out at 10.2 Gbps and force the console down to 4K@60Hz. This cable carries the full 48 Gbps that HDMI 2.1 requires, unlocking 4K@120Hz gaming, VRR, ALLM, and the smoother frame pacing PS5 and Xbox Series X were designed for.

High-purity tinned copper conductors carry the 48 Gbps signal without bottleneck. Triple shielding (foil + braid + drain wire) suppresses electrical interference at the higher bandwidth where shielding matters most. Gold-plated 19-pin connectors resist corrosion. Flexible PVC jacket bends easily behind a TV.
Each cable is sample-tested during production for full 48 Gbps continuity, HDMI 2.1 feature support, and connector retention. Manufactured to RoHS environmental standards. If a cable arrives defective or stops working in normal use, Cable Leader handles replacement requests directly — no manufacturer redirects.
