Macrosilicon MS2130(S?) Dongle, Tailed, USB-C / A Plug, No Loop Out - This Is The One I Bought
I picked up one of these for 18.98€ on Amazon, which had a better selection and clearer information about Ugreen device models than on eBay.
The version I have does not have HDMI loop-out, it's a single input endpoint.
This is the highest-resolution Macrosilicon device on the market as of May 2026.
