📡 What is HDMI Bandwidth — And Why It Matters

Bandwidth determines how much data your cable can carry. Higher resolutions and refresh rates require more bandwidth. For example, 4K @ 60Hz needs around 18 Gbps, while 4K @ 120Hz or 8K requires up to 48 Gbps. Using a low-bandwidth cable can limit your display performance.

Recommended Product for This Scenario:
9-Pin Serial F-F 1.8M — ₹899
RS-232 • Female to Female • Coupler • 1.8 Meter
