The 6 Best 4k Gaming Monitors - Winter 2019
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 gaming monitor with G-SYNC support we've tested so far is the Acer Predator X27. It's a great IPS monitor overall with good picture quality, wide viewing angles, and good peak brightness, making it suitable for a bright room.

Gamers will appreciate the 120Hz refresh rate and the fast response time that delivers fast-moving content with almost no blur trail. This monitor supports NVIDIA's G-SYNC for a very wide range of refresh rates, ensuring a tear-free gaming experience. Also, if you play a lot of HDR games, you should note that it offers the best HDR experience of the monitors we've tested so far, mainly due to the excellent HDR peak brightness. The remarkable color gamut is also the best we've tested so far.

Unfortunately, the monitor, just like most IPS monitors, doesn't deliver good dark room performance; blacks look gray due to the lacking contrast ratio and poor black uniformity, despite the existence of a local dimming feature that can't help much. Overall, this is an expensive monitor that delivers great performance in most uses and will satisfy those who choose it.

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. The 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.
