Where can I go in and update this name in Input switcher?

by smdifansmfjsmsnd

I went into Settings > Watching TV > External Inputs > Manage Inputs and it shows the correct name but on the Input switcher it shows a name it came up with all on its own.

Sony Bravia x800h Android

Isn't that the host name of the device?
