I have an old small CRT from Sony and wonder if I could probably connect a Nintendo Swich there. Would be funny😅
If you have a suitable connection, then this is not a problem.
Without hdmi connection it will be difficult, possibly an adapter
Clearly with an adabter it could go but these are expensive and remember that the switch yes 16-9 expands.
No you can't HDMI too
Scart does not work
