LG 27GR83Q Review: 1440p 240Hz 1ms FreeSync IPS Gaming Monitor

The LG 27GR83Q is a 27" 1440p 240Hz gaming monitor based on an IPS panel with a fast 1ms GtG response time and a wide 95% DCI-P3 color gamut.

Bottom Line

The LG 27GR83Q is an excellent value 27″ 1440p 240Hz IPS gaming monitor. However, be sure to check out all the alternatives based on the same panel as well.


The LG 27GR83Q is a 1440p 240Hz IPS gaming monitor that offers excellent value for the money, making it ideal for mixed use.

Image Quality

Based on an IPS panel, the LG 27GR83Q-B monitor provides you with 178° wide viewing angles, which ensure that the image will remain flawless regardless of the angle you’re looking at it.

Further, it has a wide 95% DCI-P3 (~130% sRGB gamut volume) gamut coverage for rich and saturated colors.

There’s also an sRGB emulation mode in case you wish to clamp the native gamut down to ~100% sRGB for accurate SDR colors, though most users will prefer the extra vibrancy of the wide gamut.

Next, the LG 27GR83Q has a strong 400-nit peak brightness, meaning that it can get more than bright enough to mitigate glare even in well-lit rooms.

As expected from an IPS panel display, there’s some (manageable) IPS glow and the static contrast ratio is low at around 1,000:1. Blacks won’t be as deep as that of VA panel displays around this price range, but you do get faster response times, smoother VRR performance and wider viewing angles.

The monitor also supports HDR (High Dynamic Range) and has VESA’s entry-level DisplayHDR 400 certification.

However, due to its low contrast ratio, low brightness and lack of full-array local dimming solution or an OLED panel, you’re not getting a proper HDR viewing experience.

Some HDR content can still look a bit better than SDR thanks to the monitor’s wide color gamut and dithered 10-bit color depth support, resulting in in smoother gradients.

Lastly, thanks to its 2560×1440 Quad HD resolution, the LG 27GR83Q provides you with a decent pixel density of 108.79 PPI (pixels per inch), resulting in sharp details and text with no scaling necessary.

1440p is also significantly less demanding on the GPU than 4K UHD, allowing for higher frame rates while still offering decent visual fidelity.


While the jump from 144Hz to 240Hz is not as big as the difference between 60Hz and 100Hz+, the difference is still there and it is noticeable. Given that you can achieve 240FPS, you get lower input latency and clearer motion.

So, if you have a powerful enough PC rig to run fast-paced competitive games at ~240FPS, it’s definitely worth the investment.

Moving on, the LG UltraGear 27GR83Q also has a rapid 1ms GtG pixel response time speed, ensuring that there’s no ghosting behind fast-moving objects.

There are four response time overdrive modes: Off, Normal, Fast and Faster.

For gaming at 240Hz, we recommend the default Fast mode since Faster adds too much pixel overshoot (inverse ghosting).

However, if you’re using variable refresh rate around 60FPS or gaming at a fixed 60Hz refresh rate, you should dial back the overdrive to Normal for the best results.

Input lag performance is excellent as well with around 3ms of delay, which is imperceptible.

The backlight of the monitor is flicker-free and there’s a low-blue light filter available in the OSD (On-Screen Display) menu.

The LG 27GR83Q supports variable refresh rate with AMD FreeSync Premium and NVIDIA G-SYNC Compatible certifications for tear-free gameplay up to 240FPS. VRR is also supported via the HDMI 2.1 VRR standard.

Beneath the bottom bezel of the screen is a directional joystick for quick and easy navigation through the OSD menu. You can also use LG’s On-Screen Control desktop application.

Useful gaming features include Black Stabilizer (improves visibility in dark scenes by altering the gamma curvature), crosshair overlays and a refresh rate tracker.

Besides the standard image adjustment tools (brightness, contrast, color temperature presets, etc.), the LG 27GR83Q also offers some advanced settings, including color temperature fine-tuning in 500K increments, 6-aix hue/saturation, four gamma modes, sharpness, aspect ratio (4:3, full wide) and automatic input detection.

Additionally, the LG 27GR83Q supports hardware calibration via LG’s True Color Pro software, allowing you to store calibration info on the monitor itself instead of as an ICC profile.

Design & Connectivity

LG 27GR83Q B Review

The stand of the monitor is robust and offers a good range of ergonomics, including up to 110mm height adjustment, 90° clockwise pivot, -5°/15° tilt and 100x100mm VESA mount compatibility. You cannot swivel the screen to the left/right.

The screen has a light matte anti-glare coating that prevents reflections without making the image too grainy.

Connectivity options are abundant and include two HDMI 2.1 ports with full 48 Gbps, DisplayPort 1.4 with DSC, a dual-USB 3.0 hub and a headphone jack with DTS Headphone:X support.

The audio jack can also be used as a combo jack (microphone + headphones) when the monitor is connected to the PC via a USB cable.

The LG 27GR83Q also offers excellent console compatibility since it can downscale a 4K 120Hz signal and supports both HDR and VRR.

Price & Similar Monitors

The LG 27GR83Q price ranges from $350 to $500. At $350, it offers excellent value for the money, but at $500, it’s too expensive.

There are a few more 1440p 240Hz IPS gaming monitors that use the same (or a very similar) panel:

Unless you need MBR, USB-C or KVM, we recommend getting whichever model is the cheapest as the image quality, performance and features are very similar across these displays. Acer also has a 1440p 240Hz IPS model, the XV272U W2, but it has bad quality control and overdrive implementation, so you should avoid it.

All in all, the LG 27GR83Q is an excellent value 1440p 240Hz IPS gaming monitor if you can find it on sale for $350. However, keep in mind that the other mentioned models also offer additional features and can be found for a similar sale price.
