## Description
Adds a settings for automatic resolution switching. When enabled, the
app tries to output content at the video stream's resolution.
For example, if playing 1080p content on a 4K TV, the actual output by
the Android TV device will be 1080p.
This works in hand-in-hand with automatic refresh rate switching. So
enabling both allows for the output to match both refresh rate and
content resolution. Outputting the best refresh rate is preferred over
best resolution.
Also, shows the current display mode in the playback debug info.
