USB-C Display Link Budget Calculator

DISPLAY STREAM

Estimate the uncompressed link load

Enter one repeated display mode. Mixed-monitor desks should be calculated separately and summed.

Display countCount displays using this same resolution, refresh, and color depth.Display widthUse the active horizontal pixel count, such as 3840 for 4K UHD.Display heightUse the active vertical pixel count, such as 2160 for 4K UHD.Refresh rateUse the target mode shown in the monitor and host specifications.

Color depthHigher color depth increases the uncompressed stream.Display lanesUSB-C Alt Mode may reserve two lanes for USB 3 data.Link classSelect the documented host-to-dock link mode, not the connector shape.

Why a payload estimate is only one gate

USB-C is the connector shape, not proof of a display path. This comparison uses standard link payload classes and an explicit 5% timing allowance. Exact blanking, compression, color mode, host limits, dock topology, and cable support can move a real setup above or below the estimate.
