I have a late-2015 imac 27 inch and will be acquiring a 2018 mac mini in the near future. Mac mini will be used largely headless for a plex server, but I would like to have a monitor that works well with both the imac and the mac mini, as needed. Any suggestions? Prefer high quality screen but no graphic design work or anything. Something similar to the imac screen would be great. Budget is 6-800$.
