I’ve got these things locally available in the $50-60 range. This being a generic brand, I imagine a buncha those are available globally. Anyone tried 'em, do they work OK with modern desktops (gnome, plasma)? Touch? DP-Alt or are they DisplayLink? Do they have PD?
Sellers are helpful nada, same with youtube videos, just marketing fluff.
I’ve used a non-touch DisplayLink USB monitor before. You might run into issues with getting it to work properly based on your OS. DisplayLink and Debian were not friends, and took a lot of messing around with drivers and other apps to get it to work. I can’t speak for other OSs though
