Contrast ratio: A good contrast ratio makes the dark areas of a screen easier to see when you’re watching a movie or playing a game.Great monitors should also include a USB 3.0 hub so you can connect peripherals like keyboards, mice, and webcams, since modern laptops come with fewer and fewer ports of their own. Ports: HDMI and DisplayPort connections are both requirements for any decent 4K monitor, and the best ones will also include a USB-C port that can send a display signal and charge a connected laptop at the same time.

You’ll pay between $700 and $900 for a great 32-inch model. Price: A great 27-inch 4K monitor should cost less than $600, and decent budget models should cost less than $400.Display technology: Your 4K monitor’s display should be IPS, not TN (or VA), because IPS panels provide far better viewing angles and color reproduction.We didn’t look at any 4K monitors bigger than 32 inches because they take up too much desk space.
