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, however, 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. For those who like to game in a dark room, you 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 has a unique design that stands out, 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; however, while it won't be noticeable for most people, input lag is slightly higher if you play at 60Hz.

This monitor uses an IPS panel, which provides good viewing angles, so images remain accurate even if you're not directly in front of the screen. Unfortunately, its contrast ratio is sub-par and black uniformity is poor, making it less ideal for dark rooms, though this is typical of 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.

All in all, if you're looking for a 4k G-SYNC monitor with all the bells and whistles, get this one.

The best budget 4k gaming monitor we've tested so far is the LG 27UD58-B. It has a similar design to the LG 27UK650-W, but with a black finish and a stand that isn't as versatile since it doesn't allow many ergonomic adjustments. On the upside, this monitor delivers a good gaming performance thanks to its very low input and FreeSync support that ensures tear free-gaming.

Its response time is slightly slower than the other LG monitors, and some people might notice a little more blur in fast-motion. When compared to other LG monitors, it's lacking HDR support, which doesn't add much anyway.

Overall, this is a good 4k gaming monitor that will please most casual gamers, and it's the best 4k gaming monitor in the budget category.
