We have a lovely little TV In our van but it doesn’t have an HDMI port just SCART & VGA sockets - I’ve been given a Firestick for my birthday- it has an HDMI on the end of the lead - I’ve seen (on Amazon) a converter from HDMI to SCART - is this what I’d need ? Or do I need a SCART to HDMI converter as I believe there’s a difference & one will work but the other will not
