Hi, Unfortunately, I'm not able to get my new Philips 499P display working with native 5120x1440 resolution on my late 2014 iMac 5K. I'm seriously considering buying maxed out 2018 mac mini, as my new workstation. Does anyone successfully connected 5120x1440 display to 2018 mac mini? I don't really want to go through the whole return process if it won't work. Thanks!
