Do you plan to mount some of your screens in portrait (vertical) orientation? No problem. Once you've added your player to XOGO Manager using its simple PIN code, just use the drop-down menu to tell the player whether it should display content in landscape or portrait orientation.
Some players don't support portrait. FireTV/Firestick falls into that category at the time of this writing. No problem! You can handle this from the design side. Please see this video tutorial: https://youtu.be/c-eTkGTq2wk
