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 have a couple different units. Both recommendable, sub $100 range. Magnetic flaps are handy for slapping them to sheet metal like case sides. One is a trifold, the other a bifold. They stack and sit side by side nicely in many arrangements. Usb-c power pass through lets you Daisy chain a single high current input, they’re pretty slick. I’ve had both of the screens and a gl.inet travel router on a single power feed Daisy chained in series, no issues. Oh man, touch screen though? Have no experience unfortunately.
