LG 27GL83A Review: 1440p 144Hz 1ms IPS FreeSync Gaming Monitor

The LG 27GL83A is an affordable 27" 1440p 144Hz gaming monitor with an IPS panel, a rapid 1ms response time speed, and more cool features!

Bottom Line

For the price, you can’t go wrong with the LG 27GL83A. You’re getting one of the fastest IPS panels available for virtually zero ghosting in games while the colors and details are crystal-clear and vivid.


The LG 27GL83A is essentially the sRGB color gamut version of the LG 27GL850 which has a wider DCI-P3 color gamut.

Due to this, it’s also cheaper. So, if the LG 27GL850 is out of your budget range or you can’t seem to catch it in stock, the LG 27GL83A might be the solution for you.

LG 27GL850 Vs LG 27GL83A

The LG 27GL83A display is based on an IPS panel with wide 178-degree viewing angles, 10-bit color depth support, 1ms (GtG) response time, 1440p resolution, and a 350-nit peak brightness while its static contrast ratio varies between 700:1 and 1,000:1 depending on the unit.

You will find the same specs in the Nano IPS panel of the LG 27GL850.

The main difference between these two monitors is that the LG 27GL83A has an sRGB color gamut backlight, whereas the 27GL850 covers a wider DCI-P3 color space.

The wider color gamut allows for more vibrant and lifelike colors in HDR (High Dynamic Range) compatible games, movies, and other content. Most video games and web content, however, use the sRGB color space.

With the LG 27GL850, you can limit the 98% DCI-P3 color gamut (equivalent to 135% sRGB) to ~100% sRGB via the provided emulated profile in the OSD menu for the regular content to be color-accurate.

The LG 27GL83A, on the other hand, only covers 99% of the sRGB color space.

Srgb Vs Dci P3

Now, for a really good HDR viewing experience, a monitor needs more than just a wide color gamut.

The peak luminance should hit at least 600-nits (ideally over 1,000-nits) while the contrast ratio needs to be much higher, which can be resolved by implementing localized dimming.

The LG 27GL850 supports none of the above-mentioned features. In fact, neither the LG 27GL850 nor the LG 27GL83A even quality for VESA’s entry-level DisplayHDR 400 certification.

So, even though the LG 27GL850 has a wide color gamut, it still lacks certain display capabilities for a proper HDR viewing experience.

Whether or not the more vivid colors of the LG 27GL850 are worth the extra ~$100 over the LG 27GL83A is up to the user’s personal preference and budget.

If most video games you play don’t even support HDR or DCI-P3, the LG 27GL83A is obviously the more cost-effective choice.

The wide color gamut isn’t the main selling point of the GL850 though, it’s the rapid 1ms response time speed, which is available on the GL83A as well.

Image Quality

Moving back to the image quality of the LG 27GL83A, the monitor is factory-calibrated and covers 99% of the sRGB color space.

The colors are accurate and precise and even fit for some entry-level color-critical work. Although there’s no wide color gamut support, the colors are excellent overall, especially considering the monitor’s price.

1440p resolution ensures crisp details and plenty of screen real estate on 27″ sized monitors thanks to the ideal pixel-per-inch ratio of ~108 PPI, which eliminates the need for any scaling.

As it’s the case with all IPS panels without local dimming, the contrast ratio rarely surpasses 1,000:1, meaning that blacks won’t be as deep as that of VA panel displays, which, naturally, have other disadvantages of their own.

While VA panels have a higher static contrast ratio of ~3,000:1, they don’t have as vibrant colors or good viewing angles as IPS panels. Moreover, they have slower response times resulting in visible smearing in fast-paced games.

Another disadvantage of IPS panels is IPS glow. If you’re watching dark scenes in a dark room, you’ll be able to notice some ‘glowing’ around the corners of the screen. This is the expected downside of IPS panels, and it’s manageable.

No monitor is perfect, especially at this price range, so compromises have to be made. If you want a great image quality as well as fast pixel response time, IPS is the way to go.


Lg 27gl83a Vs Lg 27gl850

The LG 27GL83A, along with the LG 27GL850, is the fastest IPS panel currently available with only 1ms (GtG) pixel response time speed, which will eliminate all prominent ghosting and motion blur in fast-paced games.

In order to get the specified 1ms speed, you need to set the response time overdrive option to ‘Faster’ in the OSD (On-Screen Display) menu of the monitor. However, this will introduce inverse ghosting, aka pixel overshoot.

Luckily, with the overdrive option set to ‘Fast,’ you won’t get any overshoot nor visible trailing behind fast-moving objects. The speed may not be technically 1ms, but it’s more than fast enough to keep the pixels up with the 144Hz refresh rate.

The LG 27GL83A input lag is only ~4ms, which makes for imperceptible delay between your actions and the result on the screen.

AMD FreeSync is supported with a 48-144Hz VRR (variable refresh rate) range over DisplayPort and 48-100Hz over HDMI for tear-free gameplay.

The monitor is certified as G-SYNC compatible by NVIDIA, so FreeSync will work without issue with compatible NVIDIA GPUs.


The LG 27GL83A monitor offers plenty of useful features for gaming, including Black Stabilizer (improves visibility of objects in shadows), Crosshair (custom crosshair overlays), and pre-calibrated picture presets (FPS, RTS, Reader Mode, sRGB, and two customizable Gamer profiles).

Navigation through the OSD menu is a breeze thanks to the 5-way joystick placed beneath the bottom bezel of the screen while the menu itself is intuitive and well-organized.

The monitor supports HDR10, but only via software emulation, so it can accept the HDR signal, but the viewing experience won’t really be improved.

There are four gamma modes as well as advanced color temperature adjustment (by 500K increments), but there’s no 6-axis hue/saturation option which you can adjust in your graphics card’s drivers anyway.

The backlight of the monitor is flicker-free, and there’s an integrated low-blue light filter.

Design & Connectivity

The LG 27GL83A design consists of ultra-thin matte-black bezels and subtle ‘gamery-red’ color accents. The stand is sturdy and offers decent ergonomics, including up to 110mm height adjustment, 90° pivot, -5°/15° tilt, and 100x100mm VESA mount compatibility. You cannot swivel the stand to the left/right, though.

There’s no RGB lighting of any kind while the monitor has a low-haze anti-glare, matte coating, which effectively eliminates reflections, but doesn’t make the picture appear grainy.

Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports, and a headphones jack. Both DP and HDMI support 144Hz at 1440p, but if you enable FreeSync, the refresh rate is limited to 100Hz over HDMI. Unlike the LG 27GL850, the GL83A doesn’t have a USB hub.

Price & Similar Monitors

The LG 27GL83A price amounts to ~$380, which is excellent value/price.

The LG 27GL850 goes for ~$500, so if that’s out of your budget or you don’t care for the wide color gamut (either in general or because your favorite games don’t support it), the 27GL83A is for you.

In fact, we recommend the LG 27GL83A over the $600 27″ 1440p 144Hz IPS models such as the Aorus AD27QD, the Aorus FI27Q-P, the ASUS PG279QZ, etc.


All in all, the LG 27GL83A 1440p 144Hz IPS gaming monitor delivers an immersive image quality, buttery smooth performance, and plenty of features.

Its HDR image quality is underwhelming, but for a really HDR display, you’d have to invest a lot more and give up some of the features the LG 27GL83A offers.
