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 4-digit 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
