Starting video in Steam Link - Plus start up video feature request

[Former user]

First, want to say great product, love it. Just got a big box licence.

My issue is when I start up big box with a start up video on Steam Link, the video very small on my TV but full screen on my monitor. Is there a setting I need to make it full on the link?

Second, a feature request to have random start up video play for variety. For example instead of big box looking for startupvideo.mp4 it will randomly select a file in a startup video folder.
