Question Some doubts about USB ability to carry HDMI signals

[doragasu]

I have one of those USB-C hubs with HDMI output typically used on laptops to attach one more monitor. The question is: can I use it with my desktop? For reference, my desktop has an ASUS Prime X570-P motherboard, with USB 3.2 but no USB-C ports.

I have seen there are some USB hubs that are plugged to a USB-A host and have USB-C ports, for example this one, but I suspect that the USB-C port in these can only carry data, no HDMI (unless you put a display controller inbetween). So would this work?

If it doesn't, my second option is buying an internal PCIe card with USB-C ports, something like this. But even in this case I don't know if it would work...

correct, the usb-c port have to support display output
doesn't sound like the pcie card support display output as it is not in the spec

Thanks for the info.

I also asked on Mastodon and got a very clear and detailed explanation, in case anyone is interested: https://social.treehouse.systems/@marcan/112095607065526102

TL;DR: It will not work neither for the USB hub nor for the PCIe card. At least not with severe caveats.
