Not stated
A USB-C port that carries power and not video
The cable seats, the plug is reversible, and something usually happens: the laptop may charge, a drive may appear. None of that is evidence about video.
What each node contributes
Machine USB-C port · decides this
Whether a given USB-C port sends video depends on support for DisplayPort Alt Mode, which VESA describes as an Alternate Mode functional extension of the USB Type-C interface. No laptop listing in this catalog names its ports, let alone their modes.
USB-C cable
USB-C cables are defined by the USB Implementers Forum and differ in what they carry. The connector is the same either way.
Screen USB-C input
Some screens here name a USB-C input. None of them state which modes that input accepts.
Why it looks fine on the page
USB-C is a connector specification. Power delivery, data and video are separate capabilities that a given port may or may not implement, and the socket looks identical in every case. A port that charges the machine has demonstrated that it does power. It has demonstrated nothing at all about whether it will drive a screen, and the two are decided independently.

What is actually limited here
The machine port, if it does not support the alternate mode that carries a picture.
What to check instead
- Whether the screen listing names a USB-C input, or only a USB-C socket for power.
- Whether the machine manufacturer publishes video support for that specific port, since the retail listing does not.
- Whether there is a second route — an HDMI or DisplayPort input on the same screen — that is stated more clearly.
- Whether the cable in the box is described as carrying video, or only as a charging cable.
