Bandwidth Calculator
Video Signal Bandwidth Calculator
This tool helps you calculate the bandwidth needed for a video signal based on its resolution, refresh rate, bit depth, and timing settings. It shows whether common connections like HDMI®, DisplayPort™ or USB-C® can handle your setup without or with compression like DSC. Use the presets for popular resolutions or customize the inputs to fit your specific needs, and see a visual comparison of resolutions and connection limits.

USB-C®1
¹Direct USB-C® to USB-C® like from laptop to the monitor connections (using Alt Mode without USB data) provide the full bandwidth equivalent to the corresponding DisplayPort™ standard found in the center column.
²Real bandwidth is approximately 80% of the specified rate for older standards and 97% for newer ones due to encoding overhead.
³Using a USB-C® hub with USB data ports typically uses 2 of the 4 high-speed lanes for data, leaving only 2 lanes for video, effectively halving the available bandwidth.

⁴The chart shows the most commonly used resolutions today and the maximum window sizes for various video standards with base settings: 16:9 ratio, 60Hz, 8-bit, DSC used if available.
