I spent 3 weeks, went through 3 DP to HDMI adapters by different dealers bought a monitor dock and sent back three desktops  to two different dealers trying to solve a connection problem. These desktops are not 2018 models according to my tech guy. They may have been refurbished in 2018 but they are not 2018 models. They were manufactured before Windows 10 was offered as a OS therefore no drivers were ever created for them so you may run into compatibility problems where some every day thing just won't work and you can't figure out why??? Here it is!!!
