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 shouldn't have any issues placing it in a bright room.
The LG 27GN750-B is a good monitor for most uses, and it performs best as a gaming monitor. Gamers should 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.
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.
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.
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.
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.
Decent for HDR gaming, mainly due to its impressive gaming performance. It has a really high 240Hz refresh rate, an outstanding response time resulting in clear motion, and an extremely low input lag. Unfortunately, HDR doesn't look good on this monitor as it doesn't display a wide color gamut and can't get bright enough to make highlights pop.
The 27GN750-B has a simple design like most other LG UltraGear monitors. It's mainly black with a red ring on the back and it has a wide-set stand. It fits well into any gaming setup and doesn't stand out in an office environment, either.
The stand supports the monitor well but there's still some wobble. Its feet are wide and there's space to place stuff in front of the stand.
Disappointing ergonomics. The 27GN750 can rotate into portrait mode, but only clockwise, so the inputs that are housed on the right side are on top when it's in portrait mode. This is a bit unfortunate if you have short cables.
The borders are thin and aren't distracting if used in a multi-monitor setup.
The screen of the 27GN750-B isn't very thick on its own, but the stand takes up a bit of space.
The 27GN750 has decent build quality, like other UltraGear monitors. It's made entirely out of plastic but there are no obvious build quality issues.
Sub-par contrast ratio, which is expected from an IPS panel. Blacks appear closer to gray when viewed in the dark.
The 27GN750 doesn't have a local dimming feature. The above video is provided for reference only.
Great peak brightness. It gets bright enough to combat glare and it remains very consistent across different content. It's slightly less bright than the LG 27GL650F-B.
Just okay HDR peak brightness. On 'Gamer 1' Picture Mode, it gets decently bright but not enough to make highlights pop in HDR.
As is the case with most IPS monitors, the 27GN750-B has a great horizontal viewing angle. The image remains accurate when viewed from the side, which is ideal for co-op gaming.
The 27GN750 has a passable vertical viewing angle. The edges of the screen may appear darker if you sit too close and you lose some image accuracy if it's mounted above eye level. This isn't as good as the LG 34GN850-B.
Outstanding gray uniformity. The edges of the screen are a bit darker, but it shouldn't be noticeable with most content.
Black uniformity isn't bad for an IPS monitor. Despite the visible clouding and some backlight bleed, it's much better than the Dell Alienware AW2720HF, which is another 240Hz monitor.
The 27GN750 has alright out-of-the-box color accuracy. Most colors and shades of gray are inaccurate, and the color temperature is warmer than the 6500K target, giving the image a red/yellow tint. The gamma does an okay job at following the curve, but most scenes are brighter than they should be.
Excellent color accuracy after calibration. There are almost no inaccuracies with most colors and the color temperature is at the target. However, the gamma isn't perfect and dark scenes aren't as dark as they should be.

The 27GN750-B has an excellent SDR color gamut. It covers nearly all of the sRGB color space used in most content and it has good coverage of the wider Adobe RGB color space, although it might not be enough for professional photo editors.
Excellent color volume. Due to its low contrast ratio, it can't display dark, saturated colors well.
Okay HDR color gamut, but the 27GN750 can't display a wide color gamut for HDR content. Check out the ViewSonic XG270 if you want a monitor with a wide color gamut.
Mediocre HDR color volume. It's limited by the lack of a wide color gamut and low contrast ratio, so it can't display most colors at a wide range of luminance levels.
There are no signs of temporary image retention.
Excellent gradient handling, but not as good as other 10-bit panels like the LG 27GL650F-B. There's some banding in the darker shades.
The 27GN750 has some very minor vertical color bleed, but this isn't noticeable in regular content.
The 27GN750-B has very good reflection handling. The matte finish diffuses moderate amounts of light really well. In rooms with direct sunlight, the reflections might be distracting to some.
Decent text clarity. The diagonal lines on the letters R and N are clearer when enabling ClearType (top photo).
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The 27GN750-B has an outstanding response time. Motion looks really clear and the best Overdrive setting is 'Fast'. Setting it to 'Fastest' has significant overshoot and causes visible artifacts.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The 27GN750 has a fantastic response time at 60Hz. There's minimal motion blur with fast-moving objects, which is great news for console gamers. It's recommended to leave the Overdrive setting to 'Off', as there's overshoot on the other settings. This is a much better response time than the Dell Alienware AW2720HF.
The 27GN750 has a flicker-free backlight, which helps reduce eye strain.
Unfortunately, the 27GN750 doesn't have a black frame insertion feature to help reduce motion blur.
The 27GN750-B has an outstanding refresh rate. It supports FreeSync VRR, and NVIDIA certifies it as G-SYNC compatible. VRR doesn't work over HDMI because the screen kept flickering when enabled.
The 27GN750 has an extremely low input lag. The input lag slightly increases with VRR enabled, but this shouldn't be a problem for most. The input lag for 10-bit HDR was measured at 60Hz because we couldn't get a proper image at 120Hz or 240Hz over an HDMI connection.
