I have my Steam Deck connected to the docking station, which is connected to my TV via HDMI.

When in desktop mode, whether the TV is the primary display or not, Steam Link launches on the Steam Deck display. Obviously, I want it to launch on the TV instead.

While Steam itself supports streaming games it does not support desktop sharing like Steam Link and the Steam Link app does.

I did not find any setting in Steam Link or otherwise that would allow me to select/specify the display to use - to launch it or change it to the TV.
