1) LG 27GN950-B
Max Refresh Rate
Variable Refresh Rate
The best 4k gaming monitor we’ve tested is the LG 27GN950-B. It has a large 27 inch screen that provides incredible immersion and plenty of space for multitasking. Its IPS panel has wide viewing angles, so images remain accurate when viewed from the side, great for sharing content or playing co-op games. It doesn’t handle reflections all that well, but it gets bright enough to overcome glare easily. The ergonomics are somewhat disappointing, though, as it doesn’t allow for swivel adjustment at all.
Motion handling is fantastic thanks to its exceptional response time and high refresh rate, resulting in clear images in fast-moving scenes. However, it requires a graphics card with Display Stream Compression technology to achieve its full 144Hz refresh rate since there’s no HDMI 2.1 port. The flicker-free backlight helps minimize image duplication, and it has both FreeSync support and G-SYNC compatibility to reduce screen tearing.
It can deliver a pretty decent HDR experience. It has a good wide color gamut and gets bright enough to bring out some highlights. Unfortunately, it has a low contrast ratio that makes blacks look gray in the dark, and even though it has a local dimming feature, it performs poorly. On the upside, it has two USB 3.0 ports for charging and a Picture-in-Picture mode that lets you display two input signals at once. Overall, it’s a great gaming monitor that should satisfy casual and serious gamers alike.
2) Acer Predator XB273K
The Acer Predator XB273K is the best 4k gaming monitor with native G-SYNC support that we’ve tested. It’s a great gaming model that provides an incredibly immersive experience with its 4k resolution and large 27 inch screen. It’s impressively well-built with a tripod-like stand that feels very sturdy. It allows for height, swivel, and tilt adjustments so that you can place the screen easily at your optimal viewing position. It has decent viewing angles to maintain image accuracy when viewed from the side, making it great for sharing content and playing co-op games.
Motion handling is good thanks to its great response time and 144Hz refresh rate, resulting in clear images in fast-moving scenes. It supports G-SYNC natively to deliver a nearly tear-free gaming experience; however, it doesn’t support FreeSync at all, which means that it might not work if you upgrade your graphics card in the future to one that only has FreeSync. There’s HDR support, but unfortunately, it doesn’t get bright enough to make highlights pop. Also, it has a low contrast ratio that makes blacks look grayish, making it less ideal for gaming in the dark.
There are quite a few additional features, including a pair of speakers and four USB ports. There’s even some customizable RGB lighting that shines onto the desk to set the mood. It handles reflections well and gets bright for most lighting conditions, and if it isn’t enough, it includes two anti-glare panels to further reduce glare. Overall, it’s a feature-rich and versatile monitor that should please most people.
3) Dell S2721QS
The best 4k gaming monitor in the budget category we’ve tested is the Dell S2721QS. It’s a great 27 inch model designed for productivity but with enough gaming performance to satisfy most casual gamers. It has a good build quality despite its budget price and a stand that allows for all manner of adjustments so that you can place the screen at your optimal viewing position. It has wide viewing angles, making it a great choice for co-op gaming, and it gets bright enough to provide good visibility in well-lit environments.
Input lag is very low, which results in a responsive gaming experience. It has a reasonably fast response time, but the refresh rate is limited to 60Hz. It supports FreeSync to minimize screen tearing and is compatible with NVIDIA’s G-SYNC too. There’s HDR10 support; however, it doesn’t get bright enough to make highlights pop, and it lacks a local dimming feature. Also, it has a low contrast ratio that makes blacks look gray.
There are only a few additional features. There’s a pair of integrated speakers if you don’t have dedicated ones, and its Picture-in-Picture mode lets you display images from two input sources at the same time, which can be useful for multitaskers or streamers running on two computers. The backlight is entirely flicker-free, great for reducing eye strain on long gaming sessions. All in all, it’s a versatile and wallet-friendly monitor that’s worth checking out.
