The most ergonomic option, and a requirement for our picks, is a monitor’s ability to attach to a monitor arm via a VESA mount. Stands and VESA-mount support: If your monitor doesn’t allow you to properly align it for correct posture, your body can pay the price.Software controls make things easier for everyone. Monitor-control software: Monitor buttons are notoriously small and fiddly, which can make them annoying to use for most people and especially difficult for those with limited use of their hands.Though the accuracy of factory-calibrated monitors is generally great, professional calibration can usually improve it. If you’re doing professional image work on the monitor, we recommend either calibrating it yourself or hiring a professional. Coverage of the wider DCI-P3 color gamut is a plus. For the best image quality, your monitor should also cover as much of the sRGB color gamut as possible the more gamut coverage a monitor provides, the wider the range of colors it can accurately represent.

The best 4K monitors come calibrated from their manufacturers and thus have better color accuracy than those that don’t. Color accuracy and color gamut: For any kind of photo, video, or graphics work, a monitor’s color accuracy ensures that your images look the way you intend them to when they appear on another screen or in print.Having a good contrast ratio is a little more important than having accurate color-you can often fix inaccurate color after the fact by calibrating the monitor yourself, but a poor contrast ratio is harder to address. A contrast ratio of 1000:1 or higher (note that higher is better) is typical of IPS panels. We measure each monitor’s contrast ratio during our testing, instead of relying on the manufacturer’s listing. 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 that you can connect peripherals such as 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 models also include a USB-C port that can send a display signal and charge a connected laptop at the same time.You can buy a high-quality 32-inch model for $700 to $900. Price: An excellent 27-inch 4K monitor should cost less than $700, and a decent budget model should cost $400 or less.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 occupy too much desk space. Size: A 27-inch monitor is large enough to take advantage of some of 4K’s extra screen resolution yet isn’t too large to use on a desk.
