10 LG 27UD88
This LG monitor is a few years old, but it’s still an excellent option for users who aren’t doing any intensive video or photo work on their Mac minis. It’s a great balance of performance and affordability.
It’s a 27-inch USB-C monitor with 4K resolution. It also comes with FreeSync anti-tearing and various customizable presets. It’s USB-C compatible, but also features two HDMI inputs so you have options when connecting to your Mac. Get it here.
