📺 Why HDMI 2.1 / 48 Gbps matters

• For real 8K at 60 Hz (or smooth 4K at 120 Hz) — which is what HDMI 2.1 supports — you need a cable with 48 Gbps bandwidth. Older cables (HDMI 2.0 and below) may only support up to 18–24 Gbps, limiting resolution or refresh rate. 

• HDMI 2.1 cables also support newer features like eARC, HDR10 / Dolby Vision, variable refresh rate (VRR), smoother gaming/streaming — all useful if you have a modern console, 8K/4K TV or PC setup.
