The LG 27GP83B-B is a great monitor all-around, and it delivers a great gaming experience. It's the first true replacement to the very popular LG 27GL83A-B, and LG has succeeded at delivering a noticeable improvement over the previous model. It has a fast refresh rate, outstanding response time, and incredibly low input lag. The 27 inch, 1440p IPS screen is great for pretty much any usage, as it delivers great screen real estate, decent text clarity for office use, and for gamers, it doesn't tax your graphics card as much as 4k displays. It's limited in connectivity and extra features, with no USB hub, limited ergonomics, and no support for multiple inputs. It's not as good for a dark room, though, as it has low contrast and mediocre black uniformity, as expected for an IPS panel.
The LG 27GP83B is a great monitor for pretty much any usage. It's a great gaming monitor with low input lag and an incredible response time. The 27 inch, 1440p screen is great for office use, multimedia, or media creation. It has exceptional gradient handling and can display a wide color gamut, making it a great choice for media creation. It looks great in bright settings, with very good reflection handling and great peak brightness. It's not as good in a dark room, though, as it has a low contrast ratio and mediocre black uniformity.
The LG 27GP83B is a very good office monitor. The 27 inch, 1440p display delivers a great amount of screen real estate to work, and it has decent text clarity. It has very good reflection handling and high peak brightness in SDR, so glare shouldn't be an issue in a brighter office. It has wide viewing angles, so you can comfortably share your screen with someone else, but the stand has limited ergonomics, so it might be hard to place it in an ideal viewing position.
The LG 27GP83B-B is a great gaming monitor. It has low input lag, so you can respond instantly to the action on-screen, and it has an incredible response time, resulting in clear motion with little blur. It supports FreeSync variable refresh rate technology (VRR), but it's also certified by NVIDIA to work with their G-SYNC VRR format. It performs almost as well when gaming at 60Hz, making this a great choice for console gamers.
The LG 27GP83B is a very good monitor for multimedia, as long as you're not in a dark room. The 27 inch, 1440p screen is great for watching videos. It has wide viewing angles, great for sharing the screen with a few friends, as well as very good reflection handling and high peak brightness, so glare shouldn't be an issue. On the other hand, since it has an IPS panel, contrast is low, so it doesn't look as good in a dark room.
The LG 27GP83B is a great monitor for media creation. The 27 inch, 1440p screen makes it easier to see more of your work at once, and the wide viewing angles are great for sharing the screen with someone else. It has excellent gray uniformity and exceptional gradient handling, and it can display a wide color gamut. Unfortunately, it has limited ergonomics, so it might be hard to place in an ideal viewing position, and it's not as well-suited for a dark room due to its low contrast ratio.
The LG 27GP83B is a decent monitor for HDR gaming, mainly due to its gaming performance. It has outstanding low input lag, an incredibly fast response time, and supports FreeSync variable refresh rate technology. Unfortunately, it has a low contrast ratio, one of the most important factors for a good HDR experience, and it doesn't have a local dimming feature. It has decent peak brightness in HDR, though, and games in HDR can stand out.
The chevron-shaped stand is wide but doesn't take up much space. Unfortunately, it doesn't prevent the stand from wobbling.
Unfortunately, the LG 27GP83B has disappointing ergonomics, so it might be difficult to place it in an ideal viewing position. It has a great height adjustment range but a limited tilt range and can't swivel. It can rotate to portrait orientation for a dual-monitor setup, which is great, but only in one direction.
There's a red ring around the mounting arm and inputs, but other than that, it's pretty plain. There's no RGB bias-lighting, and the notch in the stand for cable management isn't very useful.
The LG 27GP83B has decent built quality, similar to the LG 32GP850-B. The stand and frame are entirely plastic and feel a bit cheap, but it's fairly solid overall. We didn't notice any bubbling or any other issues around the bezels.
Unfortunately, due to the IPS panel used in the LG 27GP83B, it has disappointing contrast. This results in blacks that look gray in a dark room but isn't very noticeable in a bright room. Contrast can vary between units, and although these results are a bit on the low side for an IPS panel, they're within the range posted by LG for this monitor (700:1 minimum, 1000:1 typical).
Calibrating this monitor impacted the contrast more than usual. Before calibration, we measured a contrast ratio of 944:1, which is closer to the typical contrast ratio for this model. The difference between the post-calibration and pre-calibration contrast isn't noticeable.
The LG 27GP83B doesn't have a local dimming feature. The video is for reference only, so you can see how the local dimming feature on other displays compares to one without local dimming.
The LG 27GP83B has great peak brightness in SDR. It's bright enough to overcome glare in most rooms, and there's no variation in brightness with different content.
These measurements were taken after calibration, in the 'Gamer 1' Picture Mode, with the backlight at max. The peak brightness can change depending on which mode you're using.
The LG 27GP83B has decent peak brightness in HDR. It's bright enough to take advantage of HDR in most games, but small highlights in movies don't stand out as much as they should.
These measurements were taken before calibration, in the 'Gamer 1' Picture Mode, with the backlight at max and HDR enabled. The peak brightness can change depending on which mode you're using.
As expected for an IPS monitor, the LG 27GP83B has impressive horizontal viewing angles. The sides of the screen should still appear uniform even if you're sitting really close to the screen or if you're sharing the screen with someone else.
This monitor has okay vertical viewing angles. Anybody standing above the screen should still see an accurate image, and there shouldn't be any noticeable issues placing the monitor in a portrait orientation.
Like most monitors on the market, the LG 27GP83B has excellent gray uniformity. The left and right sides of the screen are a bit darker than the center, but it's not really noticeable with most content. In near-dark scenes, the uniformity is nearly perfect, with no noticeable issues.
The LG 27GP83B has mediocre black uniformity. The entire screen looks blue due to the low contrast ratio. There are some signs of backlight bleed, especially from the bottom-left corner. Note that black uniformity varies between units; let us know if you get one with better uniformity than the unit we bought.
The LG 27GP83B we bought and tested has decent accuracy out of the box. Colors are pretty accurate overall, with no real noticeable issues, but the white balance is off, and the color temperature is warm. Gamma doesn't follow the sRGB target curve at all, and all scenes are brighter than they should be.
Note that, unlike the LG 32GP850-B, this monitor isn't factory calibrated, and the pre-calibration accuracy can vary between units.
After calibration, this monitor has superb accuracy. There are no remaining issues with the white balance, colors are displayed accurately, and gamma follows the sRGB target curve almost perfectly. The color temperature is very close to our target of 6500K.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit due to manufacturing tolerances, even for the same model.
The LG 27GP83B has an outstanding SDR color gamut. It has perfect coverage of the sRGB color space used by most desktop and web content. It also has excellent coverage of the wider Adobe RGB color space used mainly for content creation but can't display the full range of greens or blues.
This monitor has fantastic color volume. It's mainly limited by the low contrast ratio, as it can't display saturated colors at low luminance levels. Like almost all LCDs, pure blues aren't as bright as pure white, but this isn't very noticeable.
The LG 27GP83B has a very good HDR color gamut. It can display most of the DCI P3 color space used by current HDR content, but coverage of the wider Rec. 2020 color space is just okay. These results are slightly worse than the LG 32GP850-B, but it's not really noticeable with most content.
This monitor has okay color volume in HDR. It's limited by the incomplete HDR color gamut, and due to the low contrast ratio, it can't display saturated colors at low luminance levels.
There are no signs of temporary image retention on this monitor, but it can vary between units.
The LG 27GP83B has superb gradient handling. There's almost no noticeable banding anywhere, which is great.
There's slight vertical color bleed on our unit, but it's not really noticeable with regular content.
The LG 27GP83B has very good reflection handling. The matte finish diffuses light across the screen, decreasing their intensity. Glare shouldn't be an issue unless you're in a really bright room.
Update 07/20/2021: We increased the text clarity score to 7.5 for consistency with other monitors we've tested with similar performance.
The LG 27GP83B has decent text clarity, similar to the LG 32GP850-B. We strongly recommend running the Windows ClearType (top photo) wizard if you're on a PC. There are some font issues in apps that don't support ClearType.
|Response Time Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The LG 27GP83B has an incredibly fast response time at its max refresh rate. We recommend the 'Normal' overdrive setting, but the 'Fast' setting isn't terrible either, and some people may prefer it. The 'Faster' setting has terrible overshoot in many transitions, resulting in a noticeable trail of inverse ghosting behind fast-moving objects.
|Response Time Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
Even when gaming at 60Hz, this monitor has an outstanding response time. Almost all transitions at our recommended 'Off' setting fall well within the refresh rate window. Unfortunately, as this monitor doesn't support variable overdrive, we recommend manually switching the Response Time setting when you switch refresh rates. Although the 'Normal' setting we recommend at the max refresh rate is okay, there's more noticeable overshoot. The 'Fast' setting has even worse overshoot, and 'Faster' is unusable.
The backlight is completely flicker-free, which is great, as it can reduce eye strain.
The LG 27GP83B doesn't have an optional black frame insertion feature, commonly known as Motion Blur Reduction on LG monitors. The higher-end model, the LG 27GP850-B, has an optional black frame insertion feature, but it can't be enabled if the variable refresh rate feature is activated.
This monitor has a very high refresh rate, great for gaming. Unlike the LG 27GP850-B, there's no option to overclock it to 180Hz, but this is a pretty minor difference overall. It supports AMD's FreeSync variable refresh rate technology, allowing the monitor to match the frame rate output by your graphics card. It's also certified by NVIDIA to work with their G-SYNC compatible mode, which only works over DisplayPort and only with recent NVIDIA graphics cards. Over HDMI, the maximum refresh rate is 144Hz.
The LG 27GP83B has outstanding low input lag, resulting in a very responsive gaming experience, even when gaming at 60Hz on older consoles. The input lag with variable refresh rate enabled is slightly higher, but it's not a noticeable difference.
Unfortunately, we aren't able to test the HDR input lag at the maximum refresh rate, as we can only test HDR over HDMI, and the maximum refresh rate of this monitor isn't supported over HDMI. We don't expect HDR to make any difference to the input lag.
The 27 inch, 1440p screen offers a high pixel density and great amount of screen real estate for multitasking, without being as taxing on your system as a 4k display.
The LG 27GP83B has a few additional features available, most of them gaming-oriented. Some of them include:
This monitor has the same updated On-Screen Display as the other 2021 LG UltraGear monitors. Due to the increased number of animations, it's a bit slower, but still very easy to use.
We tested the 27 inch LG 27GP83B-B, which is the only size available. There are other monitors in LG's 2021 UltraGear lineup, some of which are listed below, but we don't expect our review to be valid for those models.

The ASUS ROG Strix XG27AQ and the LG 27GP83B-B perform very similarly, but the ASUS is a bit more robust. The ASUS has much better ergonomics, a built-in USB hub, slightly better text clarity, and it feels better-built. If those things don't matter to you, though, the LG has a slightly better response time, with less noticeable overshoot. The LG also has much lower input lag at 60Hz, making it a better choice for console gamers.
The Acer Nitro XV272U KVbmiiprzx is a bit better than the LG 27GP83B-B for most people, with one major exception that may be a deal-breaker for some users. The Acer has much better ergonomics, an optional black frame insertion feature, better text clarity, and better connectivity, with a built-in USB hub. Unfortunately, though, the Acer isn't very bright, so if you're in a room with even a moderate amount of light, the LG is the better choice.
The LG 27GP83B-B and the LG 32GP850-B are very similar overall, but the 32GP850-B has a larger screen. The 32" model has a slightly faster refresh rate, and it has an optional black frame insertion feature, but other than that, there are no significant differences between these models.
The ASUS ROG Strix XG27UQ is better than the LG 27GP83B-B for the most part, but some people might still prefer the LG. The ASUS has better ergonomics and much better text clarity, and it has an optional black frame insertion feature. On the other hand, the LG has better reflection handling, a faster refresh rate, and a better response time. The ASUS has a higher resolution screen, but this may actually be a downside for some gamers, as it's more taxing on your PC.
