LG 27GL83A-B monitor review

Susan Fernandez February 02 2022

If you think about buying a new monitor, you might probably pay attention to the LG 27GL83A-B, which has a lot of interesting features. But is it really worth buying? This article will help you to make a decision.

Note, that while selecting a gaming monitor or a monitor for work you need to pay attention to such features as resolution, refresh rates, and contrast ratio. These parameters might seem to be the same for every monitor, but there are always subtle differences that could make your life much better or maybe just not enough comfortable.

If you are a web designer and you need accurate color reproduction, your monitor must contain at least 99% of the sRGB color gamut. This is not a big problem for everyday users, but if you are going to work with pictures or videos on your monitor, the only way to get an accurate image is to calibrate it yourself or pay attention to other parameters.


The LG 28GL83A monitor comes equipped with a variety of gaming-friendly features, including a Black Stabilizer (for removing objects in the shadows), Crosshair (for custom crosshair overlays), and several other helpful capabilities. It's simple and straightforward to navigate around an OSD menu using a five-way joystick underneath the screen. There are four Gammas modes as well as color temperature adjustment in 500k increments. The monitors' front light is flicker-free, and the filter includes low white light filtering.


The LG 27GL83A monitor is compatible with the G-SYNC feature, but it requires an Nvidia video card and an internet connection to work, along with a good BIOS version. It's not possible to use the G-SYNC feature in combination with overclocking or FreeSync in AMD GPUs. Moreover, G-SYNC compatible monitors have a bit of input lag, but LG claims that the LG 27GL83A monitor has no input lag at all.

HDR mode

The LG 27GL83A supports the HDR10, which is a good thing. Unfortunately, LG did not provide enough information about what exactly enables this feature or how it works, but we know that there are certain aspects that make it work well like high resolution and its AH-IPS panel type.

High dynamic range

This monitor also features with a high dynamic range, which makes colors more vibrant and realistic. LG claims that the LG 27GL83A monitor has an 80 percent DCI-P3 color gamut coverage, making it able to display almost all natural colors for realistic results.

Differences Between Sizes And Variants

The LG 27GM83, for example, has a screen size of 24.5 inches. The LG GSM 27G83b replaced it at the time of its release in 2021. It was quite similar to the LG 27GM83, but it had longer refresh speeds. Other models appear on this chart aside from LG UltraGear. We'll go through each one a little more in detail. Although test methods such as gray uniformity can vary across units, they do exist.

Design & Connectivity

The LG 27GL83A monitor has subtle color accents and ultra-thin brushed bezels. This stand has a robust frame with decent ergonomic features, up to 110 m height adjustment, and a 90° pivot. It's impossible to turn the stand to the left. There is no RGB light, and the LCD displays have a low-shine finish that efficiently blocks light reflections but is not grainy when connected via HDMI or DisplayPort 1.5. Connectivity choices include two HDMI 2.0 ports and one DisplayPort 1.5 port as well as headphone jacks.

It has wide viewing angles, which would be a nice addition to an ultra-wide monitor with a diagonal of 28 inches, which makes it larger than most monitors on the market. The bottom bezel is also thicker than LG's other ultra-wide monitors.


The LG 27gl83A is one of the fastest LCD displays in the market. It has a pixel resolution of 1 ms and eliminates ghosting in fast-paced games. To achieve a specific 1ms speed, you must change the overdrive setting in the OSD Menu to "Faster" in the OSD Menu. However, inverse ghosts or pixels outstretch are introduced as a result. The overdrive function is quick, so there's no visible trail following fast-moving objects. This isn't technically '1 ms', but it's sufficiently rapid for 144Hz refresh rates.

It has such useful features as local dimming and a reader mode that will help you both play games with fun or read in a dark room without any discomfort.

The LG 27GL83A has a 144 Hz refresh rate, which is fine for use in 1080p. However, when you're playing games like Battlefield 1 or Far Cry 5 at 4K resolution, the LG 27GL83A cannot keep up with your graphics card's output. LG claims that the LG 27GL83A monitor refresh rate is 144 Hz, which is still good for 4K gaming.

Gaming performance is not quite good for gamers willing to play games in 4K resolution. This monitor refresh rate is high, and it's fine for 1080p gaming, but you can't enjoy your games at ultra-high resolutions such as 3840 x 2160 with this monitor. That is why users don`t quite often choose this option as a gaming monitor.

Image quality

Our IPS display is factory-calibrated, covering the entire color gamut straight from the box. Because of the ideal pixels per inch (PPI) of 108 PPI, 27′′ sized displays benefit from a high resolution of 1440 P, which eliminates scaling requirements. Contrast ratios in non-dimming IPS displays seldom exceed 1000:1. This implies that black graphics on VA panels aren't as deep as they would be on traditional CRT monitors and offer various disadvantages as a result.

LG 27GL83A-B monitor is quite good at watching dark scenes because LG monitors are well-known for their high contrast. LG 27GL83A-B provides an extended color gamut. LG has equipped its UltraGear series with AMD's Freesync technology to ensure tear-free gaming without input lag in every scenario, even when FPS drops below 40 through 74 Hz.

LG 27GL83A-B has vibrant colors that are slightly oversaturated. This monitor is easy on the eyes, even after long hours of gameplay. LG has optimized its overdrive technology to eliminate all ghosting and inverse ghosting that results from high-speed motion.

What about IPS panels?

LG also has IPS panel technology and LG 27GL83A-B monitor has a pixel density of 108 PPI (pixels per inch), which is far greater than the 2.7 to 3.7 PPI range of standard monitors on the market today. The IPS panel allows users to enjoy LG 27GL83A-B monitor with full clarity in many different angles. LG's IPS panel technology also helps LG 27GL83A-B monitor achieve lower power consumption and works to reduce eye fatigue during long periods of use.

Finally, its great image quality is more than just subjective. LG 27GL83A-B monitor has a delta E of only 0.51, which is considered to be excellent color accuracy, especially for the price point LG has set for this monitor.

How can you rate the monitor`s RGB lighting?

LG monitors provide the ability to adjust the intensity of the LEDs, but those adjustments can only be made using LG's OSD (On Screen Display) for adjusting the monitor's brightness and contrast. The RGB lighting of this monitor model LG 27GL83A is bright and strong, but what matters is how it affects the image quality LG 27GL83A-B. LG monitors can produce 100% of the sRGB color gamut, which LG calls 'UltraWide Color Gamut' (UWCG).

SRGB color space is a color space that has been used on the Internet from the early days and is also called 'internet colors'. This LG 27GL83A monitor has an sRGB coverage of 99%. LG monitors can cover almost all of the NTSC color gamut, which still isn't as widely used today. LG 27GL83A-B monitor covers 72% of NTSC standard, which LG calls 'NTSC 72% Color Gamut'.

A wide color gamut LG 27GL83A monitor LG 27GL83A-B is good for watching movies and LG has built some advanced color technology to present the original movie colors. Saturated colors LG 27GL83A monitor LG 27GL83A-B can be made brighter.

Test results

This stand is extremely robust; the LG27GL841A to B models have few if any wobbles. Because of poor ergonomics on the LG 27GL841B monitor, viewing angles might be challenging. The height adjustment on this gadget works well. Just like most UltraGear displays, the back of this screen is covered in red circles.

The response time of this monitor LG 27GL841B is 5 ms, which LG claims is 'superfast.' LG's marketing teams are very generous with this specification. LG 27GL841A monitor has a pixel response time of 4ms. That figure can be found on many LG displays. In special, due to the response time, LG 27GL841B monitor can be considered as one of the quickest monitors because the LG 27GL841A monitor has every gamer would need. LG 27GL8325-DP review shows LG has really made some drastic improvements since last year's LG24GM77 gaming monitors.

The contrast ratio was also tested. LG 27GL841A monitor has a contrast ratio of 3.000:1. LG 27GL8325-DP review shows LG's IPS display could achieve a much deeper black than that, but LG 27GL841B monitor also only has a relatively poor maximum brightness level. Contrast ratio effects on your LG 27GL841B monitor are discussed in LG 27GL8325-DP review.

As for a gaming monitor, this model LG 27GL841A-B will be a great option due to its fast response time and LG 27GL8325-DP review shows LG's IPS display could achieve a much deeper black than that.
