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 used two of these - one that’s 1080p which I’ve used for years, and one that’s 1440p that broke after a short time (but that was my fault).
I don’t really use them as touch screens. I once tried with my then-work-Macbook, but it was mapped to the wrong screen, so I stopped. Since then I’ve been using it exclusively as a screen.
The colors aren’t perfect, but otherwise it’s absolutely acceptable quality - not much worse than a 5-10 year old monitor IMO. I’m driving it through Micro USB & HDMI. Be aware that somehow every couple weeks I have to continuously unplug and replug the HDMI for the monitor to recognize the signal, don’t know why.
This was probably not very helpful, sorry! If there are any specific tests you’d like me to do, I’ll gladly do them. I bought mine at a fair and have never found it online, so you won’t be able to buy it, but there’s probably much better ones available now.
