@mandy@joe the weird thing about displays is that the one you get with an iMac is almost certainly going to be better than the LG UltraFine you'd use with a Mac mini, and probably cheaper as a combo.
@adiabatic I have a 2009 iMac. Mr TDH gave me a ViewSonic that has excellent height adjustment so I would it use with a Mini and sometimes my work laptop. If I keep another Mac as long as I have kept the iMac, it would be nice to upgrade the monitor. /@joe
@adiabatic I was thinking just the monitor I have and one of those little portable ones - how great that would be to use when I am sitting at a folding table to program a machine! /@joe
@mandy Having more momitors to play with is always ideal. I have three myself and using them as supporting monitors. I enjoy the ViewSonic brand you have since they're good.
