I have a Samsung Tab 6 with a very nice 8" oled screen. I want to use it in combo with my Bluetooth controller for my Steam Games (for a little more reading room). I’ve tried Steam Link and it works, but the lag of my wifi make it quite unplayable so, since i already have a dock and an hdmi cable, i was thinking of buying a second dock ( as the one in the photo). Anyone has done anything similar? Can you suggest any free android app to do the mirroring from the deck to my tablet??
