Your Mac or MacBook's display is already gorgeous, but if you're in the market for a second display or even something larger than what you have, a 4K monitor is a huge step in the right direction. If you want to try and maintain the same level of definition as your current display, here are the best 4K monitors for your Mac.
One of LG's latest monitors, the 4K 27UK850-W sports USB-C, HDR support via 2 HDMI ports and a DisplayPort, a headphone jack, and two down-stream USB-A ports. It also has excellent viewing angles, thanks to its IPS panel, and its gray-to-gray response time is a blazing-fast five milliseconds.
BenQ's 32-inch monitor is somewhat expensive. Still, it offers excellent features for the creative pro, like several different modes (including Darkroom) for photo and video editing, a built-in SD card reader, as well as a 5-port USB hub, HDMI ports, and mini and regular DisplayPorts.
This inexpensive monitor from LG has the company's excellent IPS panel, as well as a swift 5-millisecond response time. With a refresh rate of 60Hz, excellent viewing angles, and a designated gaming mode, this is a solid all-around monitor for most people. It doesn't offer much in terms of inputs (HDMI and DisplayPort only), but it'll do in a pinch.
LG's big 32-inch 32UL950-W is not only a Thunderbolt 3 monitor, meaning you can daisy chain monitors together but also has quite a few ports. With one Thunderbolt 3 port, one USB-C, two USB-A, an HDMI, DisplayPort port, and a headphone jack, this monitor has tons of connectivity to attach all your favorite devices. Plus, it's 60hz screen refresh rate, 600 nits brightness, and beautiful P3 wide color gamut makes this screen look amazing right out of the box.
Phillips' 276E8VJSB is a monitor built for folks who might spend a little bit too much time staring at a screen. This monitor includes a low blue mode, and flicker free technology to make it easier on your eyes during extended use. It also has 10-bit colors to deliver images that are more lifelike than ever before.
A couple of suggestions
Of course, when it comes to using a newer MacBook, you're not only going to want USB-C (since it's the only port the MacBook lineup has anymore), but you're likely going to want some extra ports. That's where the LG 27UK850 (opens in new tab) comes in. Since it can charge your MacBook, MacBook Air, or 13-inch MacBook Pro, and it also features two USB-A ports, two HDMI ports, a display port, and a headphone jack, making it not only a fantastic monitor but a whole hub for connectivity.
If the price is your only concern, the LG 27UD58-B (opens in new tab) is probably the monitor you should pick up. Since it was released a couple of years ago, it received a huge price cut recently, and that's no laughing matter.
