I just got a Steam Link, and I've searched on the steam forums, around reddit, and I can't find an updated answer for this, so I apologize if this has been asked before me.
I'm on a Mac, with dual monitors, and the Steam Link, when any game is launched (windowed or full screen) shows both monitors. The second monitor will be a black rectangle and the main monitor will be full screen, but the problem is that because it shows both monitors, I can hardly see anything going on.
Short of pulling the plug on my second monitor every time I want to use the Steam Link, how can I get it to just show the main display through Steam Link? I found a post 5 months ago from a Valve employee that made it sound like they were going to add this feature of only showing one monitor through Steam Link, but that was over 5 months ago and I can't find anything more current. Is there a setting I'm missing in either the Steam client or on the Steam Link?
Or, is this just for Windows, and Mac users continue to get the shaft on Steam support?
