The LG 27GL83A is a 27″ 1440p 144Hz gaming monitor based on an IPS panel with wide viewing angles, vibrant colors, and fast response time speed.

Additionally, it has an ergonomic stand and supports a variable refresh rate for tear-free gameplay. On top of all that, it’s affordable!

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 specifications in the popular and more expensive LG 27GL850, so what’s the difference?

The LG 27GL850 has a native wide color gamut support of ~98% DCI-P3 (equivalent to ~135% sRGB). This results in more saturated colors, especially reds and greens.

When watching content intended for the DCI-P3 color gamut, which includes mostly HDR (High Dynamic Range) games and movies, the colors become richer and more vibrant – closer to the way the content creator intended.

However, when watching content that’s intended for sRGB (most games and web content), the colors become over-saturated.

Some users prefer this over-saturated look, while others prefer to see the colors as intended.

This is why the LG 27GL850 has an sRGB mode that can clamp its native ~135% sRGB gamut to ~100%, allowing you to choose how the monitor will display colors.

Now:

The LG 27GL83A has a native 99% sRGB color gamut. So, for better or worse, it cannot over-saturate colors.

It can still display the same ~135% sRGB, despite having only ~99% sRGB specified, but only when displaying HDR content.

This way, you still get extra color vibrancy when watching HDR content and accurate colors when viewing sRGB content – you just can’t take advantage of the wide gamut for SDR (Standard Dynamic Range), that is non-HDR, content.

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.

So, thanks to its wide color gamut support, some HDR content/scenes will look a bit better on the LG 27GL83A, but it is far from the ‘true’ HDR viewing experience, which is only available on much more expensive monitors.

Regardless, HDR is not a selling point of the 27GL83A, it’s merely a bonus feature.

Image Quality

The monitor is factory-calibrated and covers ~99% of the sRGB color space right out of the box; the colors are accurate and precise and even fit for some entry-level color-critical work.

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, at least at this price range.

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.

Performance

Lg 27gl83a Vs Lg 27gl850

The LG 27GL83A is one the fastest IPS panel monitors with a 1ms (GtG) pixel response time speed, which prevents ghosting 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.

Features

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.

Besides the standard image settings, there are four gamma modes and color temperature fine-tuning (in 500K increments).

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 headphone 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 and it’s our top-recommended 27″ 1440p 144Hz IPS gaming monitor.
