***EDIT 2***: You *may not* need the IR extender. Just click Function Test and then say Yes when it asks you if your devices turned off or on. Sorry for not making this clear. If you have a model that does ask for one, try any 1/8″ audio jack which might fool the tv into thinking you have the IR extender connected.
This video describes how to give your inputs custom names on your Samsung smart tv. If there is a better/easier way, please let me (and others) know.
By default you can’t change the name of the input under ‘Edit Name’ from the ‘Source’ selector.
You have to create a custom input source to have a custom name as far as I can tell.
Menu (on remote) .. System .. Device Manager .. Universal Remote Setup .. (Follow instruction in the video)
