The LG 27GN750-B is a 240Hz monitor in LG's UltraGear lineup. It has a 1080p, IPS panel with native FreeSync support, and it's certified by NVIDIA for G-SYNC compatibility too. Motion looks exceptionally clear on this monitor due to its outstanding response time both at its max refresh rate and at 60Hz. The input lag is extremely low, so your actions are registered quickly when gaming. With its IPS panel, it has wide viewing angles, but it has a low contrast ratio, so it's not an ideal choice for dark room viewing. Unfortunately, even though it supports HDR10, it can't display a wide color gamut, so HDR content doesn't look much different from SDR content. This monitor can get bright enough to combat glare and it has good reflection handling, so you won't have any issues placing it in a bright room.
Our Verdict
The LG 27GN750-B is a good monitor for most uses, and it performs best as a gaming monitor. Gamers will appreciate the high refresh rate, outstanding motion handling, extremely low input lag, and FreeSync VRR support. It has wide viewing angles, which makes sharing your screen with coworkers or friends easier, and it performs well in bright environments because of its very good reflection handling. Unfortunately, HDR content on this monitor isn't much different than SDR content since it can't display a wide color gamut or get bright enough to bring out highlights.
- Really high refresh rate.
- Outstanding response time results in clear motion.
- Extremely low input lag.
- Low resolution.
- Disappointing ergonomics.
- Low contrast ratio.
The LG 27GN750-B is a good office monitor. It has wide viewing angles if you need to share your screen with others, it can get bright enough to combat glare, and it has very good reflection handling. Unfortunately, the 1080p resolution might be too limiting for some, but luckily it has excellent gray uniformity, so solid colors across the screen, like on a web page, look great.
- Wide viewing angles.
- Gets bright enough to combat glare.
- Low resolution.
- Disappointing ergonomics.
Impressive gaming monitor. The LG 27GN750-B has a very high 240Hz refresh rate that produces very smooth motion, it supports FreeSync VRR and it's G-SYNC compatible, and the input lag is extremely low. The response time at 60Hz is also amazing, so it's a great choice for console gaming. The 1080p resolution doesn't deliver an immersive gaming experience, but it has wide viewing angles if you want to use it for co-op gaming.
- Really high refresh rate.
- Outstanding response time results in clear motion.
- Extremely low input lag.
- Low contrast ratio.
The LG 27GN750-B is a good choice for watching videos. The 1080p resolution is too low to watch the latest 4k videos online, but it has wide viewing angles if you want to share your screen with some friends. Unfortunately, it's not good for dark room viewing as it has a low contrast ratio and black uniformity isn't the best. However, it performs well in bright rooms as it has great peak brightness and very good reflection handling.
- Wide viewing angles.
- Gets bright enough to combat glare.
- Low resolution.
- Disappointing ergonomics.
The LG 27GN750-B isn't the most ideal for media creation but it's still a good choice. The 1080p resolution is too low if you're editing 4k videos and its stand doesn't allow for a wide range of adjustments. However, it gets bright enough to combat glare, and it has very good reflection if you work in a bright environment. Unfortunately, its gradient handling isn't as good as other 10-bit panels as there's visible banding.
- Wide viewing angles.
- Gets bright enough to combat glare.
- Low resolution.
- Disappointing ergonomics.
The LG 27GN750-B is mediocre for HDR. It has limited HDR performance because it doesn't display a wide range of colors and has low peak brightness in HDR, so highlights don't pop. Also, blacks look gray in the dark, and it lacks a local dimming feature to further improve the contrast.
- Can't display a wide color gamut for HDR content.
- Low contrast ratio.
- Lacks a local dimming feature.

The LG 27GL850-B/27GL83A-B is a bit better than the LG 27GN750-B. The 27GL850-B has a 144Hz refresh rate, 1440p resolution, a wider SDR color gamut, and better gradient handling. The 27GN750-B has better contrast, a 240Hz refresh rate, and its response time is a bit better, but the response time at 60Hz is still better on the 27GL850-B.
The LG 27GN750-B and the Dell Alienware AW25212HF are similar monitors overall, but the Dell is slightly better for gaming. The Dell has a better response time both at its max refresh rate and at 60Hz, it handles reflections better, and its ergonomics are better. The LG is bigger and it supports HDR10, although content in that mode doesn't look much different from SDR.
The Acer Nitro XV273 Xbmiiprzx is a better monitor than the LG 27GN750-B. It has better ergonomics, much better out-of-the-box color accuracy, better gradient handling, and a black frame insertion feature to help reduce motion blur. The LG has better reflection handling, and it has a slightly lower input lag when playing at 60Hz.
The ViewSonic Elite XG270 is slightly better than the LG 27GN750-B. It has better ergonomics, a better response time at 60Hz and it has a black frame insertion feature. The ViewSonic also displays a wide color gamut and it has better reflection handling. Instead, the LG has a better response time at its max refresh rate, much better black uniformity, and it has a lower input lag at 60Hz.
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.
