LG 27GR75Q-B Monitor Review

This monitor has a gamer-oriented design with a dark gray plastic body. Though the monitor body has a simple aesthetic from the front, both the appearance of the tripod-based stand and the back of the monitor make it clear that LG designed this monitor for gaming.

The build quality is good. Though the stand is mostly plastic, it's solid, and there's almost no creaking. The monitor body is well constructed, and the bottom bezel is flush across the entire bottom of the screen.

The ergonomics are decent. It has a good, smooth height adjustment system, so you can easily place it in your preferred position for a long gaming session. However, it can't swivel, so it's more difficult to share your screen with another person while co-op gaming or working. The stand features a hook for cable management.

The stand supports the monitor well, and there's no wobble.

Like most LG UltraGear monitors, there's a joystick underneath the display to control the on-screen menu and power.

This monitor has a mediocre contrast ratio. Deep blacks look gray next to bright highlights in a dark room, and the monitor has no local dimming feature to further improve the contrast.

This monitor has no local dimming feature. We still film these videos on the monitor so you can compare the backlight performance with a monitor that has local dimming.

The SDR brightness is good. It remains consistent with different content and gets bright enough to fight glare in a well-lit room. However, it has more trouble overcoming glare in brighter environments, particularly if the sun shines directly on the screen. These results are from after calibration in the 'Gamer 1' Game Mode, which is the picture mode setting, with the Brightness at its max and DFC turned off.

The HDR brightness is mediocre. It doesn't get bright enough for highlights to pop against the rest of the image. Additionally, it has a slow roll-off towards its peak brightness, so highlights don't get the brightest they could. These results are in the 'Gamer 1' Game Mode in HDR with the Brightness at its max.

The horizontal viewing angle is very good. It works well if you need to share your screen with someone sitting next to you, as they'll see a consistent image from the sides, though it washes out and gets darker at very wide angles.

The vertical viewing angle is mediocre. While the image washes out and gets darker at wide angles, this isn't an issue unless you stand directly above the monitor and look down on it.

The gray uniformity is good. While the edges of the screen are slightly darker, there's minimal dirty screen effect in the center, which is great.

The black uniformity is inadequate. There's noticeable backlight bleed along the edges of the screen and some cloudiness. Additionally, there's no local dimming feature to improve this performance further.

The accuracy before calibration is decent. Colors are relatively accurate but significantly oversaturated because the monitor lacks an sRGB mode to control the color gamut. Also, the color temperature is too cold, though the white balance is good. Finally, dark scenes are too dark, and bright scenes are too bright. There aren't any locked-out settings when using the 'Gamer 1' Game Mode.

The accuracy after calibration is remarkable, and you won't notice any problems.

This monitor has an incredible SDR color gamut. It can display the entire sRGB color space used in most content. However, it only has fair coverage of the wider Adobe RGB color space used in professional photo editing, and not all colors are accurate in that color space.

The HDR color gamut is decent. It has good coverage of the commonly used DCI-P3 color space, though white is quite inaccurate. However, it has poor coverage of the wider Rec. 2020 color space, and it can't display several colors accurately in this space.

The HDR color volume is mediocre, and the monitor has trouble displaying bright and dark colors well.

The text clarity is good, and the text looks bolder with Windows ClearType (top photo) enabled. These photos are in Windows 10, and you can also see them in Windows 11 with ClearType on and with ClearType off.

The LG 27GR75Q has decent reflection handling. Content remains visible in rooms with a moderate amount of light, though it struggles with very high light levels, like next to a bright window.

The gradient handling is outstanding; you won't notice banding with most content.

Due to bandwidth limitations, the max refresh rate is limited over HDMI, but you won't have issues reaching that max refresh rate over DisplayPort.

The LG 27GR75Q-B.AUS has good motion handling across its VRR range. The 'Normal' Response Time overdrive setting provides the consistently best performance, but it has more motion blur at lower refresh rates. The 'Faster' overdrive has such a high CAD that it passes the limits of the chart, and you can see it in an alternative chart here.

The refresh rate compliance is good. Although its response time isn't fast enough to make full color transitions before the monitor draws the next frame at its max refresh rate and at 120Hz, it's better at 60Hz.

The CAD at the max refresh rate of 165Hz is good, but there's still some motion blur. The 'Normal' and 'Fast' overdrive settings have a similar total response time, but 'Fast' has less motion blur, while the 'Faster' setting has too much inverse ghosting.

The CAD at 120Hz is good. Unlike at its max refresh rate, the 'Normal' overdrive setting provides the best motion handling, so you may have to switch the setting if you change games or sources. It has the quickest response time, but there's still some blur, and 'Fast' and 'Faster' have noticeable inverse ghosting.

The CAD at 60Hz is decent. There's noticeable blur and even inverse ghosting with the 'Normal' overdrive setting. If that bothers you, turning it off results in no overshoot, but it has more blur than using the 'Normal' setting.

This monitor supports backlight strobing to reduce persistence blur. While you can adjust the brightness, the maximum brightness level is only 64 cd/m², and the minimum brightness is 14 cd/m². Additionally, image duplication is enabled with this feature.

This monitor has minimal VRR flicker with changing frame rates, which is excellent for gaming. Although it doesn't eliminate all flicker, it's really hard to notice anyway.

The backlight remains flicker-free at all brightness levels, which helps reduce eye strain if you're sensitive to flicker.

This monitor has low input lag for a responsive feel. Input lag doesn't significantly increase at low refresh rates or when you turn on backlight strobing.

The LG 27GR75Q-B.AUS works as expected with the PS5, but it can't take full advantage of it without HDMI 2.1 bandwidth and HDMI Forum VRR support.

This monitor works well with the Xbox Series X|S. It downscales a 4k signal, which is useful because the console only supports HDR in 4k.

The LG 27GR75Q works well with macOS. However, content looks washed out if you're using HDR over HDMI. If you're using a MacBook, windows return to their original position when waking the laptop up from sleep or reopening the lid.

The LG UltraGear 27GR75Q-B comes with a few extra features, including:

• Black Stabilizer: Allows you to adjust the black level so that you see opponents better.
• Crosshair: Provides different crosshair options to help assist with aiming.
• FPS Counter: Displays the frame rate of your input source.
