LG is a well-known brand in the world of electronics, and they make a wide range of products, including TVs, soundbars, phones, and home appliances, among many others. Their monitor lineup offers both gaming and office solutions, so you'll likely find what you need. LG makes more ultrawide monitors than most competitors, but they also make many 27 and 32 inch models as well. Their monitors are known for their outstanding response time and variable refresh rate support, but their stands lack good ergonomics.
The best LG monitor that we've tested with a 4k resolution is the LG 27GN950-B. It's one of their first 4k gaming models, although they've produced office monitors at this resolution, like the LG 27UK650-W. It has a high 160Hz refresh rate, but you can only achieve that refresh rate over a DisplayPort connection and with a graphics card that supports Display Stream Compression. This model has native FreeSync support, and it's compatible with NVIDIA's G-SYNC as well. Input lag is incredibly low, and even though it slightly increases with VRR enabled, most people shouldn't notice any difference. The response time is exceptionally quick whether you're playing at 144Hz or 60Hz, so fast-moving content looks smooth.
Unfortunately, because it has an IPS panel, blacks look closer to gray. There's an edge-lit local dimming feature, but it performs terribly and can be quite distracting. HDR content looks good because it displays a wide color gamut and gets fairly bright in HDR to make some highlights pop. It performs well in bright rooms thanks to the impressive peak brightness, but the reflection handling is disappointing. If you don't mind spending more money on a 4k display, the LG 48 CX OLED TV is also marketed as a monitor and supports 4k @ 120Hz over HDMI, which is great if you own a PS5 or Xbox Series X. That said, if you're looking for something with a 4k resolution, the 27GN950-B is one of the best LG monitors we've tested.
The best LG gaming monitor with a 1080p resolution that we've tested is the LG 27GN750-B. It has many of the same features as the LG 27GN950-B, except the lower resolution isn't as taxing on your graphics card, and it has a higher 240Hz refresh rate. It also has FreeSync support, G-SYNC compatibility, fantastic low input lag, and an incredible response time. There's no Black Frame Insertion feature, but with how crisp motion already looks, you likely won't need it. It has an IPS panel with wide viewing angles, great peak brightness, and good reflection handling, so it's a good choice for co-op gaming and bright rooms. It doesn't have many extra features to improve your gaming experience, but you can add a virtual crosshair for FPS games.
It supports HDR10, but sadly, it doesn't add much. It fails to display a wide color gamut, the HDR peak brightness is just okay, and due to its low contrast ratio, blacks appear closer to gray, so HDR content doesn't really look all that different from SDR. Our unit has excellent gray uniformity and okay out-of-the-box accuracy, but these may vary between units. It also has excellent gradient handling and good coverage of the Adobe RGB color space if you want to use it for some video or photo editing. Overall, this is an inexpensive gaming model and the best LG monitor with a 1080p resolution.
The best LG ultrawide monitor we've tested is the LG 34GP83A-B. It's a 34 inch model with a 3440x1440 resolution and a 21:9 aspect ratio. It gives you roughly 30% more horizontal screen space than a typical 16:9 display, which is great for game immersion and multitasking. Its IPS panel has decent viewing angles, and the screen is also slightly curved to help with visibility on the sides. It gets bright enough to fight glare in most settings, but it might struggle with intense glare and bright reflections. The stand only allows for height and tilt adjustments, but it does support a 100 x 100 VESA mount if you need swivel adjustments as well. It has full sRGB coverage and supports a wide color gamut for HDR content. It can make some highlights stand out in HDR, but don't expect a true cinematic HDR experience because it has a sub-par contrast ratio that makes blacks appear gray in the dark and no local dimming.
It delivers a very smooth and responsive gaming experience. It has a 144Hz refresh rate that you can overclock up to 160Hz and an exceptional response time, so fast motion looks clear with almost no visible ghosting. Also, screen tearing is minimal thanks to its native FreeSync support and G-SYNC compatibility. Its backlight is entirely flicker-free to eliminate image duplication and help reduce eye strain. Its USB hub consists of two USB 3.0s and a USB-B upstream port so that you can plug your peripherals directly into the monitor and have only a single cable leading to your PC. The overall build quality feels decent, although the cable management seems pretty cheap and flimsy. Nonetheless, it's a good monitor with great gaming performance and the best LG ultrawide monitor we've tested.
LG and Dell directly compete with each other as they each make office and gaming monitors. Dell's models usually have much better ergonomics, and they make smaller, more budget-friendly options. However, LG's monitors generally deliver a better HDR experience, and they make many more ultrawide options.
For the most part, ASUS makes much better gaming monitors than LG with higher refresh rates, and they also generally have better ergonomics. However, LG's lineup includes larger options with a higher resolution.
LG offers options with larger screens and higher resolutions than most of its competitors. However, its office monitors don't have as good ergonomics as Dell. Also, they still lag behind ASUS in terms of gaming, as they're only starting to make high refresh rate models. Regardless, you'll likely find what you need with LG.
LG offers three different monitor lineups: UltraGear for gaming, UltraWide, and UltraFine for office monitors. Their naming convention can be a bit confusing at first, but once you learn, it's fairly easy to tell which lineup the monitor belongs to.
LG's monitors start with a number, which indicates the size, followed by the lineup letter:
The next letter is the year: N (2020), L (2019), or K (2018). The next set of numbers relates to the model's position in their lineup. The higher the number, the higher-end it is; 600 and 650 are the lowest-end models, while 950 is the premium model.
Some models have another letter following those set of numbers, but not all of them have it. They usually represent a feature of the monitor, but it's not clear what some letters represent, like T in the LG 32GN50T-B.
Lastly, there's one final letter that simply represents what color the body is; W for white and B for black.
For example, the LG 27GN950-B is a premium 27 inch monitor in the UltraGear lineup, released in 2020, and the body is black. The LG 24GL600F is an entry-level 24 inch model from 2019 that has native FreeSync support. Lastly, the LG38WN95C-W is a premium ultrawide monitor that LG released in 2020, has a USB-C input with Thunderbolt 3 support, and the body is white.

LG makes monitors for both office use and gaming, and they're available in a wide range of sizes. Their UltraGear models usually offer great gaming performance with outstanding motion handling. They also produce more 4k and ultrawide monitors than some of their competitors, but their 1440p lineup is fairly limited. LG's options also have limited ergonomics and rarely offer any swivel adjustments, but if that isn't an issue for you, you should be happy with most of their monitors.
