Questions about this item

What is the maximum data rate the cable can sustain before it becomes the bottleneck?

The cable delivers up to 80 Gbps bi-directional bandwidth and can boost to 120 Gbps for display traffic, so the limit is the host or device capability.

How much heat or power loss should I expect when the cable runs at 240 W all day?

At 240 W Power Delivery the cable is rated for the full load; any warmth stays within normal USB-C operating limits for continuous use.

Which port feature must my laptop already have to drive a 16K display through this cable?

The host USB-C port must support DisplayPort Alternate Mode; without Alt Mode video output will not work.
