LG 27GL83A-B review
  • Quick response time
  • Up to 144 Hz refresh rate
  • Quad HD 27-inch display
  • FreeSync and G-Sync compatible
  • It does not feature built-in speakers

When it comes to ensuring immersive picture quality in every scenario, LG's UltraGear monitors usually are a good solution not only for their superb performance when playing the most demanding AAA games but also when multitasking, thanks to their big display size and unique features.

With that in mind, in this review of the LG 27GL83A-B, it's time for you to get to know in-depth the knots and bolts of a highly appraised 27-inch monitor whose extremely competitive price is just one of its most appealing attributes.

Amongst other features, the 27GL83A-B packs a stunning Quad HD screen with low input lag, high color accuracy (up to 1.07 Billion colors), and a high refresh rate (up to 144 Hz), so you can have a blur-free/ tear-free gaming experience when playing fast-paced titles.

Image Quality

LG 27GL83A-B performance
The LG 27GL83A-B features a 27-inch IPS display that provides precise color coverage (up to 99% of the sRGB color gamut) as well as wider viewing angles when compared to TN screens, although darker colors are not as realistic as we'd like them to be, this is a compromise we are more than willing to make for the sake of having a wider viewing angle when compared to TN or VA screens. 

The 27GL83A-B comes with a Quad HD resolution (2560 by 1440 pixels) and a pixel density of 108 PPI, which is excellent not only for productivity purposes but for multimedia entertainment as it delivers really crisp images.

While it's easy to get hung up on resolution, it's also essential to consider size when looking at resolution and, more to that point, pixel density. It's not the same to have a 27-inch Full HD display where you can actually see the pixels due to the density being 82 pixels per inch than having a Quad HD resolution that offers more pixels and, therefore, a more detailed and crisp image.

Dynamic range with and without HDR

This model is also HDR 10 compatible, meaning that multimedia content that you consume will have a better dynamic range, and it features a brightness of up to 350 cd/m2, as well as an aspect ratio de 16:9, giving you enough space to work comfortably. 

From day one, the LG 27GL83A-B will immerse you in a breath-taking gaming experience as it boasts an input lag of just 4 ms and response time of 1 ms (GtG) after setting the "Response Time Overdrive" option to "Faster" in the On-Screen menu.

Also, its fantastic 144 Hz refresh rate will allow you to enjoy fast-paced titles such as battle royale, racing games, and simulators, with a hyperrealistic fluidity compared to your conventional 60 Hz monitors

Just this week, we had the opportunity to review the Sceptre ‎C248W-1920RN, a curved Sceptre monitor which was great except for the fact that it didn't feature a high refresh rate (only 75 Hz) and had a low response time, meaning it was worthless for gaming purposes.

Furthermore, getting back to the review at hand, thanks to the LG 27GL83A-B's AMD FreeSync and NVIDIA G-Sync support, you'll be able to play tear-free gaming sessions over both DisplayPort and HDMI outputs.

Last but not least, you can turn on the Black Stabilizer and Dynamic Action Sync functions, so you'll be able to see your enemies on the battleground even in the darkest scenarios, as well as the Crosshair feature to enhance the gaming experience when playing first-person shooter titles.


Right under the LG logo, the LG 27GL83A-B has a 5-way joystick button that allows you to access the LG OnScreen Control software so you can adjust the image according to your needs and even choose between four pre-calibrated picture presets (FPS, RTS, sRGB, and Reader Mode) as well as two customizable gaming profiles.

In order to improve your day-to-day productivity, its display is flicker-free and there's a built-in blue light filter that will be beneficial to your eyes, especially when working at night.

Also, it has an anti-glare coating that will avoid reflections in most cases, except if you're in a very bright room. However, featuring a 350 nits brightness, we hardly see this being an issue to be honest. 

Design and Connectivity

As stated by numerous buyer reviews, this LG monitor has a decent build quality as well as an eye-catching look consisting of a matte-black cabinet with slim bezels and subtle red accents on its rear side like many other LG gaming monitors.

Despite the fact that it is entirely made out of plastic, it still delivers a solid touch, and it's very easy to set up. Also, it features a sturdy Y-shaped stand that supports tilt, height (up to 110 mm), and pivot adjustments for you to play more comfortably. It does not, however, allow you to swivel the monitor. 

Connectivity options of the LG 27GL83A-B

Moreover, it's VESA compatible, allowing you to place it on the wall in case you need to - all you need is a 100 by 100 mm VESA support -. And its connectivity solutions include a single DisplayPort 1.4 port, two HDMI 2.0 outputs (cables included), and a 3.5 mm headphone out.

Price and Similar Monitors

The LG 27GL83A-B is a reasonably-priced monitor that you can use not only for gaming/entertainment but for intensive multitasking purposes as it packs everything you would need to enjoy an immersive viewing experience in most scenarios.

However, if you're looking for an even more immersive gaming experience, then you can take a look at the LG 34WP60C-B as it boasts a stunning curved 34-inch QHD display with a higher refresh rate (up to 160 Hz), and an anti-glare coating so you can't get distracted when playing fast-paced games.

Verdict: Should you buy the LG 27GL83A-B?

All in all, the LG 27GL83A-B reviewed today is a monitor we would recommend to most users who are looking for a monitor that delivers a fantastic value for your money and can also be used as a gaming monitor. You won't go wrong with it since it offers vivid, crisp, and bright images as well as a smooth user experience when working and playing demanding games.

Also, it comes in the perfect size for you to keep focusing on your daily tasks, and it packs a good selection of terrestrial ports on its backside as well as a cable management system, so you can connect your home entertainment systems, laptop, and computer so easily.

If there is one con to be considered, it's the fact that it doesn't offer a built-in speaker. However, since most monitor built-in speakers leave much to be desired and we almost always recommend using an external audio solution this is hardly something we're going to hold against the 27GL83A-B.
