The LG 27GX704A-B is an entry-level OLED gaming monitor. It uses a third-gen WOLED panel with a 27-inch, 1440p screen and 240Hz refresh rate. It's newer than the LG 27GS95QE-B, with the main difference being that it has a glossy coating. It competes against models with similar specs and a glossy coating, like the ASUS ROG Strix OLED XG27AQDMG. It has typical gaming features, like HDMI 2.1 bandwidth, FreeSync Premium Pro, and G-SYNC Compatibility, and its WOLED panel has VESA DisplayHDR True Black 400 certification. Besides its small USB hub with two USB-A ports, it's limited in perks otherwise.
Our Verdict
The LG 27GX704A-B is fantastic for PC gaming. It offers a smooth feel thanks to its 240Hz refresh rate, and it supports all common VRR formats to reduce screen tearing. Motion looks sharp as it has a near-instantaneous response time, and its low input lag results in a responsive feel. It also delivers excellent picture quality with deep blacks in bright rooms and highlights that pop, but its colors aren't the most vivid. While it gets fairly bright, especially for an OLED, visibility is an issue in the brightest rooms.

The LG 27GX704A-B is incredible for console gaming. It supports common signals with a PS5 and Xbox Series X|S, including downscaled 4k @ 120Hz due to its HDMI 2.1 bandwidth. There's minimal blur with fast-moving objects, and it has low input lag for a responsive feel. Games also look excellent, especially in HDR, as blacks are deep and inky with no haloing, and highlights pop against the rest of the image. However, colors aren't the most vivid. It also has some connectivity issues when switching from a PC to a console, which is something to consider if you want to connect a PC alongside your console.

The LG 27GX704A-B is decent for productivity, but there are some limitations. Its wide viewing angle and ergonomic stand help if you want to share the screen with someone else. It gets bright enough to fight some glare in moderately-lit rooms, but reflections are distracting, and visibility is an issue in sunny environments. Unfortunately, there's noticeable fringing around text, so letters aren't the sharpest. It also risks burn-in with constant exposure to the same static elements over time, which is problematic if you always have the same work programs opened.

The LG 27GX704A-B is amazing for content creation. It comes with a very accurate sRGB mode, and you'll only need to calibrate it if you want to perfect the gamma tracking. It also delivers excellent picture quality with deep blacks, bright highlights that pop, and a glossy coating that results in clear images. However, its colors aren't the most vivid, and visibility is an issue in the brightest rooms as reflections are distracting. It also risks burn-in with constant exposure to the same static elements over time. Plus, with a 27-inch screen and 1440p resolution, images aren't the most detailed and sharpest.

Popular Monitor Comparisons
The LG UltraGear 27GX704A-B is a 1440p, 240Hz gaming monitor that's an entry-level option into the OLED market. As a newer model than the LG 27GS95QE-B, it comes with many of the same perks as other OLED gaming options, like support for common VRR formats, sharp motion at any refresh rate, and fantastic picture quality. However, it lacks more premium features that higher-end displays have, like DisplayPort 2.1 ports or a KVM switch.
What sets it apart is its glossy coating, which produces clear images at the cost of stronger direct reflections. This gives it a unique position in the market as an alternative to matte options with the same third-gen WOLED panel. Although it doesn't have the vivid colors of a QD-OLED or the brightness of a Tandem OLED, its low cost makes it a good entry point if you want the benefits of an OLED gaming monitor without premium features.

The LG 27GX704A-B and the LG 27GX700A-B are both 1440p OLED gaming monitors, with a few differences, mainly due to their different panels. The 27GX700A-B uses a newer Tandem OLED panel that gets brighter and has more vivid colors than the WOLED panel of the 27GX704A-B. The 27GX700A-B also has a slightly higher 280Hz refresh rate, but both monitors have the same sharp motion. They come with different stands, as the 27GX704A-B is slightly more ergonomic. Another difference is that the 27GX704A-B has a glossy coating that results in clearer images, but more mirror-like reflections, than the matte coating of the 27GX700A-B.
The LG 27GX704A-B and the ASUS ROG Strix OLED XG27AQDMG are competing 1440p, 240Hz gaming monitors. While they both have glossy coatings, the screen finish on the LG is less hazy, resulting in clearer images. There are some differences in picture quality, as the ASUS is brighter in SDR, but the LG is more accurate. The LG also has HDMI 2.1 bandwidth to take full advantage of gaming consoles, which the ASUS lacks.
The LG 27GX704A-B is newer than the LG 27GS95QE-B, carrying over many of the same features and specs. One main difference is that the 27GX704A-B has a glossy coating, as opposed to the matte coating of the 27GS95QE-B. This means the 27GX704A-B has clearer images, but more mirror-like reflections. They perform similarly otherwise, but the 27GX704A-B has the slight advantage in terms of brightness.
The LG 27GX704A-B and the Dell Alienware AW2725DF are both 1440p OLED gaming monitors. They use different panels, as the QD-OLED display of the Dell results in more vivid colors. However, the WOLED panel of the LG retains lower black levels in bright rooms, and it's the better choice for well-lit rooms as it gets brighter. The Dell has a higher 360Hz refresh rate for a smoother feel, while the ASUS has HDMI 2.1 bandwidth to take advantage of gaming consoles, which the Dell doesn't have.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
