Samsung Tab S7+ versus Blueendless HC101A

I got a Blueendless HC101A USB-C hub to experiment with my Samsung Tab S7+.

Here’s some notes.

Audio

  • 3.5mm audio output only works when VGA or HDMI is connected. Choose “Display Output” in Samsung Output Devices.

LAN

  • LAN works on my Tab S7+.
  • Settings -> Connections -> More connection settings -> Ethernet

SD

  • SD works on my Tab S7+.

Video things

  • HDMI -> DP cable doesn’t work for me to attach a monitor.
  • VGA and HDMI can be used at the same time. They get mirrored.
  • By default the Tab S7+ screen gets mirrored to the video output.
  • Until you start Dex, when you get a separate 1080p60 output from the Tab S7+.

Power things.

Powerbank: Bluebuilt CBL1130 Tester: Mustcol UD18 AC adapter: FSP060-D1AR4

  • When not connected to Tab S7+, the HC101A pulls ~1.1w from my powerbank.

  • When powering HC101A from my powerbank via USB-A - USB-C cable, it pulls ~4w.
  • When powering HC101A from my AC adapter, it charges Tab S7+ with 9V/1.8A
