BestMonitor for Mac miniiMore2020

If you're looking for a large-screen display to go with your 2020 (or older) Mac mini, you've come to the right place. Your best bet is the LG UltraFine 4K display thanks to its versatility and price. It's perfect for most people, though there are other monitors you can also consider, depending on your situation or budget.

Best Overall: LG UltraFine 4K

Here's a workhorse 4K monitor that works perfectly with the Mac mini. Though it doesn't have the Apple design aesthetic, the good stuff is all on the inside. Just like an Apple brand monitor, all of the monitor's controls are available in the settings section of your Mac.

This 24-inch display fits right into the pocket of reasonably priced and excellent quality if you don't mind the boxy black look. As for the price, you can get two of them for almost the price of one LG UltraFine 5K Display (see below).

Pros:

• Two Thunderbolt 3 ports
• Dual-screen full 4K display support
• Supports 85W charging
• Easy to set up

This LG monitor supports USB-C and Thunderbolt. The Thunderbolt 3 charges the Mac mini, and the three USB-C ports offer 5Gbps downstream. Its 27 inches big, which is about the size of Apple's larger iMac, and has a similar P3 wide color gamut with 500 nits brightness. For full 5K resolution on a larger display, the UltraFine 5K is your perfect choice.

Its biggest downfall is that it doesn't quite have that Apple aesthetic. LG has designed an attractive Edge-Arcline base for some of its monitors, which looks better with Apple products. The UltraFine 5K, unfortunately, still has that big, boxy black base.

Pros:

• Up to 5K resolution
• Designed for Apple
• Thunderbolt 3 and USB-C
• Built-in speakers, camera, and mic

Best for Widescreen: LG 34WK95U-W Nano-ISP UltraWide

Though we continued to be impressed with LG's UltraFine 5K, it's the 34WK95U-W that wins our hearts. This 5K monitor has a 5120 x 2160 resolution, 34-inch display, a Thunderbolt 3 port, an HDMI port, a DisplayPort port, and a couple of USB-A ports. It's more versatile than the UltraFine, and that's ultra-fine with us.

Pros:

• Pro-quality technology
• Nano ISP color 5K display
• USB hub
• Versatile input options

Cons:

• No built-in camera or microphone
• Poor built-in speaker quality

Bottom line

Picking the right second screen for your Mac mini is a difficult one. It's important to consider how much room you have on your desk, what you plan to use your Mac laptop for, and how much you can afford. That's why the LG UltraFine 4K is the perfect fit for most people. At 24-inches, it's big, but not too big. It's got an incredible 4K screen resolution and a variety of versatile ports for connecting all manner of peripherals.

If the LG is just a bit out of your range, the ASUS ZenScreen truly is the next best thing and it's portable! On the other end, consider the always impressive LG UltraFine 5K. The monitor is powerful and beautiful too!
