BYOD laptop over a single USB-C cable to display and room camera does not always work
USB-C can carry video, audio, USB data and power at once, but only if cable, port and host laptop all support the same profile. One weak link and you get half the picture or no mic.
Try this first
- 1Check if the laptop USB-C port supports DisplayPort Alt Mode, older laptops use USB-C only for data and power.
- 2Use a certified USB-C cable with the right markings, a random phone cable rarely carries 4K or 100W power.
- 3Verify cable length, for 4K at 60Hz a 1 meter passive cable is the safe limit, longer goes active and costs more.
- 4Test on the room system that the USB-C input delivers all three, video to the room, audio from room speakers, mic into the laptop.
- 5Stock the same brand and model cable in every room, that prevents incidents where someone grabs a thin spare that does video only.
- 6Document which laptops have Thunderbolt requirements, a Mac with Thunderbolt 3 behaves differently from a budget Windows USB-C 3.2.
When to bring us in
If laptop models keep changing and behaviour stays inconsistent, a dock with fixed interfaces is more stable than loose cables per room. Vectel can standardise it.
