"USB 2.0"
Seriously?! Are we still in ~2002 here?! Clearly, this device doesn't support full *fluid* local streaming and Xiaomi fails to mention which Dolby Vision profiles this thing supports; which it could mean, most likely it only support streaming services fake Dolby Vision (p8) and not TRUE Dolby Vision (FEL/p7) profile.
Just saying "we support Dolby Vision" is part of marketing trickery; if Xiaomi supported all DV profiles... Xiaomi what have stated such... fast, especially today.
Edit: I see this thing only supports Dolby Vision p5, that's even worse (only a few displays support p5 over p8). Wow!
Pass!
