Is it possible to use a Thunderbolt hub "in reverse"? (lemmy.ml)

I have an LG-38WN95C monitor which has a single Thunderbolt 3 port, which I use for my work M1 Macbook Pro. It's really convenient to have a single cable running from my laptop to my monitor.

But is it possible to achieve something similar with a full desktop PC? My PC has discrete graphics and a motherboard with no video-capable Thunderbolt output.

I was thinking of using a Thunderbolt hub, but most of them look like they are for use cases where the Thunderbolt cable plugs into the host machine, and then the monitor and peripherals branch off from the hub using DisplayPort / HDMI and USB.

But I want to do the reverse for the video signal. I want the hub's Thunderbolt cable plugged into my monitor, with the hub's DisplayPort link used as an input, not an output, which is passed to the monitor.

I feel like Thunderbolt's bi-directional-ness and daisy-chainability should mean this is possible, but I have little experience using Thunderbolt and I find it difficult to understand what hardware is capable of what behaviors. And with Thunderbolt hubs as expensive as they are, I am hesitant to drop significant money on a blind experiment.

The direction does not matter. Buy a USB-C to DisplayPort cable.

Funnily enough they are similar monitors. Good luck!
