Hi there, i got a nice Imac mid-2017 with two thunderbolt ports, one is already used for pro audio interface and the other for an external monitor (northing fancy, basically an old one pre-4K with HDMI and DVI connector). Now i just got a second monitor with the same connectors as the other one (HDMI and DVI) so what are my options here? I guess i will have to get a hub of some sort but i let's say i don't want to purchase a hub that will cost 4 times the cost of the used monitor i got.
