Why waste money on a steam dock? You can literally just buy a USB C to USB C power and HDMI output splitter cable for way cheaper on Amazon and save the money you'd waste on a steam dock to do the exact same thing. That's what I have and for about $15 I get the exact same results when connecting it to my TV and a power supply at the same time. Plus, you can use that cable on any device (tablet/phone) with USB C output also. It's a super handy cable to have on hand for sure. Here is a link to the exact cable I bought: https://a.co/d/0gK7JseA
