Cáp HDMI Tốt Nhất Cho Gaming 4K 120Hz

## Requirements for 4K@120Hz

You need an **Ultra High Speed HDMI cable** (48 Gbps). Standard or High Speed cables physically cannot carry enough bandwidth for 4K@120Hz + HDR.

## How to Verify

Look for the holographic label from hdmi.org. Scan the QR code to verify certification. No hologram = not certified (may still work, but no guarantee).
