I was looking for an appropriate color monitor for my Amiga 4000 and most friends told me look for the 1950 or 1960 as it supports multi-scan frequencies. It does need some fixing but no big things.
UPDATE: Stéphane fixed the monitor, thanks/merci!
I think this was the most hard monitor to find for me.
