The 6 Best 4k Gaming Monitors - Spring 2020
Reviews

The LG 27UK650-W is the best 4k gaming monitor that we've tested so far. Although this 27 inch monitor has a clean and simple design that fits better in an office setting, it can handle gaming pretty well. It doesn't have the fastest refresh rate at 60Hz, but the outstanding response time and input lag make this monitor great for gaming. If that's not enough, LG also included support for FreeSync, which provides a nearly tear-free gaming experience. Those with a recent NVIDIA 10- or 20- series graphics card can also take advantage of this technology with a driver update.

If you're looking for the best HDR experience, you won't find it here. While the monitor does support HDR, the experience is limited by the mediocre peak brightness and lack of wide color gamut. Those who like to game in a dark room may be disappointed by the IPS panel's poor contrast ratio and subpar black uniformity.

There are some advantages to LG's choice of IPS technology, though, as they're well-known to have wide viewing angles and great color accuracy out-of-the-box. All in all, if you're looking for a great 4k gaming monitor at a decent price, this is our top pick.

The best 4k G-SYNC gaming monitor we've tested so far is the Acer Predator X27. Although pricey, this monitor is a great choice for anyone who wants a high refresh rate and native G-SYNC support without compromising on resolution. It's impressively well-built and the stand provides sturdy support, but its ergonomics are rather mediocre, as it can't rotate into portrait mode. As expected of most gaming monitors, it has a fast response time and low input lag, although latency does increase slightly if you play at 60Hz.

This monitor uses an IPS panel that provides good viewing angles, so images remain accurate even if you're not seated directly in front of the screen. Sadly, it has a sub-par contrast ratio and poor black uniformity, making it less ideal for dark rooms, which is typical of most IPS panels. On the upside, it has an impressive wide color gamut and excellent peak brightness to provide a great HDR experience.

There are built-in speakers if you need them, and the backlight is flicker-free, which can help reduce eye strain for those long gaming sessions. There are also four USB 3.0 ports to charge your mobile devices, with two of them conveniently placed on the side of the monitor. Overall, this is a no-compromise monitor that should satisfy even the most demanding gamers.

The best budget 4k gaming monitor we've tested so far is the LG 27UD58-B. This monitor follows a very familiar LG design with its arc-shaped stand, except that it has much thicker bezels, which is less ideal for multi-monitor setups. Build quality is decent, even though it's entirely made of plastic, but unfortunately, the stand has bad ergonomics, as it only allows for tilt adjustments.

With a 4k resolution, images look incredibly sharp on this 27 inch screen. Motion handling is great, input lag is low, and it comes with native FreeSync support, which is good for those with an AMD graphics card or an Xbox One. The only downside is that the refresh rate is limited to 60Hz, but given the difficulty in pushing high frame rates at 4k, this shouldn't be a problem for most people. Also, like most IPS panels, this monitor doesn't look good in dark environments due to its low contrast ratio and bad black uniformity.

Being a budget monitor, there aren't many extra features to speak of. It has a black stabilizer feature that can help see objects in very dark scenes, as well as a super-resolution feature, which is used for upscaling lower resolution content. It may not be the most feature-packed monitor out there, but for the price, it's worthy of consideration.
