LG 27GN750-B Monitor Review

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 red ring on the back can't be illuminated like the LG 32GK850G-B. There's a quick-release button and there's a clip on the stand for cable management.

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).

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.

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 too, but VRR only works over a DisplayPort connection. During testing, when it was connected to a PC through HDMI, the screen flickered until it went black, and to get the image back, we had to disable Adaptive Sync from the on-screen display.

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.
