Thanks for the advice ruslan120. Yeah, I've thought about just getting two smaller (probably 24 inch) on both sides of the iMac but that's really overkill. It would be nice if someone would just make a decent monitor that looks enough cosmetically like iMac. I'm not sure if I need the resolution to be as good. I just need a bit more real-estate for secondary windows. I've been using my 12.9 iPad pro as a sidecar but it's just not cutting it. Bottom line, I'm finding it's hard to go from a two monitor setup to one even if it's 27 inch and 5K.
