Cast via cable USB C - USB C or USB C - HDMI to a TV/PC MONITOR

Hi there,

I hope you're doing well.

I'm trying to confirm whether wired screen mirroring is supported on the Meta Quest 3S.

I found the Meta support article "Cast to an external display using USB‑C, DisplayPort or HDMI cables", which states that Meta Quest 3 can mirror its display to an external screen using DisplayPort over USB‑C and lists several tested cable/adapter configurations. Link: "Transmitir en una pantalla externa con cables USB-C, DisplayPort o HDMI | Ayuda de Quest (es)"

My use case is the following:

Meta Quest 3S

USB‑C dock/hub with HDMI output

External monitor or TV

The goal is to display exactly what the user sees in the headset on the external screen through a physical cable only, without using Wi‑Fi casting, Chromecast, a browser, or a PC.

My questions are:

Does the wired external display feature supported on Quest 3 also work on Quest 3S?

Can a Quest 3S output video through a USB‑C dock/hub to HDMI?

Does the dock need to support DisplayPort Alt Mode?

Has anyone successfully tested Quest 3S → USB‑C dock → HDMI monitor/TV?

Any clarification would be greatly appreciated, especially from someone who has tested this on a Quest 3S.

Thank you for your help!
