LG 27GR83Q-B 27-inch Ultragear QHD IPS Gaming Monitor Overview

Last update on 2026-07-11 / Affiliate links / Images from Amazon Product Advertising API

The LG 27GR83Q-B belongs to LG’s popular UltraGear gaming lineup. LG released this model as part of its 2023 UltraGear series. It sits as a mid-range option below the company’s OLED gaming displays. The monitor targets gamers who want high refresh rates and excellent color accuracy without paying over $500.

The display uses an IPS (In-Plane Switching) panel with a native resolution of 2560×1440 pixels. This QHD resolution provides 77% more screen content than a standard 1080p display. Text looks sharper. Game textures show more detail. Movies and videos look cleaner.

LG designed this monitor with a 240Hz maximum refresh rate. This means the screen can update its image 240 times per second. Gamers get smoother motion, reduced blur, and a clearer picture during fast action scenes. The 1ms Gray-to-Gray response time keeps ghosting and smearing to a minimum.

The monitor earned a DisplayHDR 400 certification from VESA. It supports HDR10 content for enhanced contrast and color depth in compatible games and media. LG also included DTS Headphone:X support for spatial audio. This feature adds another layer of immersion through compatible headphones.

At its original MSRP of around $499, this monitor faced stiff competition. However, street prices have dropped significantly since launch. You can now find this monitor for around $300 or less on sale. That makes it one of the best value propositions in the 1440p 240Hz category.

Display Quality and Color Accuracy

The IPS panel inside the LG 27GR83Q-B delivers impressive color performance. Independent testing confirms the monitor covers 100% of the sRGB color gamut. It also reaches 85% of Adobe RGB and 90% of DCI-P3. These numbers are excellent for a gaming monitor at this price point.

Color accuracy stands out as one of this monitor’s best features. The uncalibrated Delta E rating measures at just 0.53. A Delta E below 2.0 is generally considered accurate enough for professional work. A score of 0.53 means colors look almost perfectly true to their intended values straight from the factory.

SDR brightness averages around 393 nits in the default picture mode. This closely matches LG’s stated 400-nit spec. In HDR mode, peak brightness reaches approximately 542 nits. This exceeds the DisplayHDR 400 specification. Bright scenes in HDR games and movies benefit from this extra luminance.

The contrast ratio measures at roughly 960:1 with a black level of 0.5 nits. This is typical for IPS technology. It falls short of VA panels that can achieve 3000:1 or higher. Dark room gaming with lots of black scenes may reveal some IPS glow or slightly washed-out blacks.

Viewing angles remain consistent thanks to the IPS panel. Colors and brightness stay accurate even when you view the screen from an angle. This makes the monitor practical for setups where you might not sit perfectly centered.

Gaming Performance and Refresh Rate

The 240Hz refresh rate places this monitor firmly in the premium tier for competitive gaming. Games feel noticeably smoother at 240Hz compared to standard 144Hz or 165Hz displays. Cursor movement feels more fluid. Enemies in first-person shooters appear clearer during fast movements.

Input lag is where this monitor truly shines. Testing shows less than 1 millisecond of input lag. This is an outstanding result. Your mouse clicks and keyboard presses translate to on-screen action almost instantly. Competitive players in games like Valorant, Counter-Strike 2, and Overwatch 2 will feel the difference.

The monitor supports both NVIDIA G-Sync Compatible mode and AMD FreeSync Premium. These adaptive sync technologies match the monitor’s refresh rate to your GPU’s frame output. The result is gameplay free from screen tearing and stuttering. You get smooth visuals even when your frame rate fluctuates.

LG included several gaming-specific features in the on-screen menu. A built-in crosshair overlay helps with aiming in shooters that lack a default crosshair. An FPS counter displays your real-time frame rate. Black Stabilizer brightens dark areas in games to help you spot enemies hiding in shadows.

To fully use the 240Hz refresh rate at 1440p, you need a powerful GPU. An NVIDIA RTX 4070 or AMD RX 7800 XT class card can push 240fps in competitive esports titles. More demanding AAA games will run at lower frame rates, but G-Sync and FreeSync keep the experience smooth regardless.

The Dell S2722DGM takes a different approach with its 27-inch curved VA panel. It offers a 165Hz refresh rate and a 2500:1 contrast ratio. The curved screen and superior contrast make it a great choice for gamers who prioritize deep blacks and immersive viewing over maximum speed.

The ASUS TUF Gaming VG27AQ1A provides a solid 27-inch IPS experience with a 170Hz refresh rate. It features ASUS’s ELMB Sync technology that combines motion blur reduction with adaptive sync. This monitor is a strong budget option for gamers who want reliable 1440p performance.

Design and Build Quality

The LG 27GR83Q-B sports a clean, understated design. It skips the aggressive gamer aesthetic that many competitors use. There are no RGB lights on the back or flashy accents. The dark gray finish blends smoothly into any desk setup, whether it’s a gaming station or an office workspace.

The monitor measures 24.2 x 18.4 x 10 inches and weighs 13.7 pounds. These dimensions keep it compact enough for most desks. The slim bezels on three sides create an almost borderless look. This is especially nice if you plan to set up a dual-monitor configuration.

LG uses a two-legged stand that provides good stability. The stand connects to the monitor through a rounded joint. This joint allows for full ergonomic adjustments. You can tilt, swivel, and adjust the height. The monitor also pivots 90 degrees into portrait mode. This is useful for reading documents, coding, or browsing vertical content.

The overall build feels solid. The plastic materials are well-assembled without any creaking or flex. Cable management is straightforward. The stand’s design leaves enough room to route cables through the back.

If you prefer to mount the monitor on a wall or arm, the 100x100mm VESA mounting pattern gives you that option. Removing the stand and attaching a monitor arm takes just a few minutes. This frees up desk space and gives you even more positioning flexibility.

Connectivity and Ports

The LG 27GR83Q-B offers a generous selection of ports for its price range. On the back of the monitor, you will find one DisplayPort 1.4 input. This handles the full 240Hz at 1440p resolution from a PC without any issues.

Two HDMI 2.1 ports sit alongside the DisplayPort. HDMI 2.1 is a significant advantage here. It supports QHD at 240Hz, which means PlayStation 5 and Xbox Series X owners can take full advantage of the monitor’s capabilities. Many competing monitors at this price only include HDMI 2.0, which caps out at lower refresh rates.

The monitor also includes two USB 3.0 downstream ports and one USB-B upstream port. These USB ports let you connect peripherals like a mouse, keyboard, or USB headset directly to the monitor. This reduces cable clutter on your desk and keeps everything tidy.

A 3.5mm headphone jack rounds out the connectivity options. This jack supports DTS Headphone:X spatial audio technology. The DTS Headphone:X feature works across all input sources. Whether you connect a PC, PlayStation, or Xbox, you get enhanced spatial audio through compatible headphones.

One thing to note is the absence of built-in speakers. LG chose to skip speakers on this model. Most gamers use headsets or external speakers, so this is rarely a dealbreaker. The money saved on speakers likely went toward better panel quality and features.

HDR Performance

The LG 27GR83Q-B carries a VESA DisplayHDR 400 certification. This is an entry-level HDR tier. It confirms the monitor meets minimum standards for HDR brightness, color gamut, and bit depth. The monitor supports HDR10 content from games, streaming services, and Blu-ray sources.

In practice, HDR performance is decent but not transformative. The peak brightness of around 542 nits in HDR mode provides a noticeable improvement over SDR content. Highlights in games like explosions and sunlight look brighter and more dynamic. Bright skies in open-world games have more punch.

However, the monitor uses edge-lit LED backlighting without local dimming zones. This limits the HDR experience significantly. True HDR monitors with mini-LED or OLED panels can produce deep blacks alongside bright highlights. The LG 27GR83Q-B cannot achieve that level of contrast in HDR mode.

Dark scenes in HDR can look a bit washed out. The IPS panel’s inherent contrast limitations become more visible with HDR enabled. Some users may prefer to keep HDR turned off for certain games, especially those with many dark environments.

That said, for a monitor in this price range, the HDR implementation is acceptable. It adds a subtle enhancement to compatible content. Just don’t expect the stunning HDR experience you would get from a $1,000+ OLED gaming monitor. Think of the HDR support here as a nice bonus rather than a primary selling point.

On-Screen Display and Software Features

The LG 27GR83Q-B uses a joystick-style controller on the bottom-center of the monitor for navigating the on-screen display (OSD). This joystick is intuitive and responsive. Pressing it opens the main menu. Tilting it in different directions moves through options quickly.

The OSD menu is well-organized and easy to use. LG divides settings into clear categories. You will find options for Game Mode, Picture Adjust, Input, and General. The Game Mode section houses most of the gaming-specific tools.

Inside Game Mode, you can activate the Black Stabilizer feature. This brightens dark areas in games to reveal hidden details. The crosshair overlay offers multiple shapes and colors. An FPS counter displays your current frame rate in a corner of the screen. A response time overdrive setting lets you choose between Normal, Fast, and Faster modes.

LG also provides several picture presets. These include Gamer 1, Gamer 2, FPS, RTS, and Vivid modes. Each preset adjusts brightness, contrast, color temperature, and response time for different use cases. The Gamer 1 and Gamer 2 slots let you save your own custom settings for quick switching.

The color temperature controls offer both preset options and custom RGB sliders. If you want to calibrate the monitor manually, you have enough controls to dial in accurate colors. The factory calibration is already excellent, so most users will not need to change much.

Performance with Consoles

The HDMI 2.1 ports make the LG 27GR83Q-B an excellent companion for modern gaming consoles. The PlayStation 5 supports up to 1440p at 120Hz through HDMI 2.1. The Xbox Series X also supports 1440p at 120Hz. Both consoles benefit from the fast response time and adaptive sync.

For Xbox Series X users, the experience is particularly smooth. The console natively supports 1440p output and works well with the monitor’s FreeSync Premium. Games like Halo Infinite and Forza Motorsport look sharp and play fluidly at high frame rates.

PlayStation 5 added 1440p output support in a system update. Games that support 120Hz on PS5 can take advantage of the monitor’s capabilities. Titles like Ratchet & Clank: Rift Apart and Spider-Man 2 in performance mode look excellent on this display.

The monitor’s Game Mode includes settings optimized for console gaming. LG’s interface makes it easy to switch between PC and console inputs. The low input lag under 1ms benefits console gamers just as much as PC gamers. Every button press on your controller registers almost instantly on screen.

Nintendo Switch users can also connect through HDMI, though the Switch is limited to 1080p at 60Hz. The monitor upscales the image to fill the 1440p panel. The result is acceptable but not as sharp as native 1440p content from other sources.

Comparison with OLED Alternatives

The biggest question many buyers face is whether to choose the LG 27GR83Q-B or spend more on an OLED monitor. OLED displays offer perfect blacks, infinite contrast ratios, and faster pixel response times. These advantages are undeniable.

The Corsair Xeneon 27QHD240 is a direct OLED competitor. It offers the same 27-inch size and 240Hz refresh rate. However, it retails at roughly $999. That is more than double the current street price of the LG 27GR83Q-B. The Corsair delivers a far superior HDR experience with perfect blacks and stunning contrast.

The LG 27GR83Q-B fights back with practical advantages. IPS panels do not suffer from burn-in risk. You can leave static content on screen for hours without worry. OLED panels can develop permanent image retention over time, especially with static HUD elements in games.

Brightness is another area where the IPS panel holds its own. The LG reaches 542 nits in HDR. Many QD-OLED and WOLED monitors struggle to maintain brightness across large white areas. For well-lit rooms, the LG 27GR83Q-B may actually provide a more comfortable viewing experience.

If your budget allows, OLED is the superior technology for gaming. The contrast and color improvements are significant. But if you want excellent gaming performance at a reasonable price with no burn-in concerns, the LG 27GR83Q-B remains a smart purchase.

Who Should Buy the LG 27GR83Q-B?

This monitor fits several types of users. Competitive gamers will love the 240Hz refresh rate and sub-1ms input lag. If you play ranked matches in fast-paced games, this monitor gives you every technical advantage short of an OLED panel.

Console gamers should seriously consider this display. The dual HDMI 2.1 ports support both a PS5 and Xbox Series X simultaneously. You can switch between consoles without unplugging cables. The QHD resolution and fast refresh rate make console games look and feel their best.

Content creators on a budget will appreciate the factory-calibrated color accuracy. A Delta E of 0.53 out of the box is remarkable. The 90% DCI-P3 coverage is suitable for photo editing and video work. It is not a full professional-grade monitor, but it handles creative tasks well.

Dual-purpose users who game and work on the same machine benefit from the clean design. The monitor does not scream “gamer” with RGB lights or aggressive styling. It looks professional during video calls and work hours. Then it transforms into a high-performance gaming display after hours.

This monitor is less ideal for users who prioritize deep blacks and high contrast. Movie watchers who frequently view content in dark rooms may prefer a VA or OLED panel. The IPS technology, while great for colors and response time, cannot match the black levels of those alternatives.

Pros and Cons Summary

The LG 27GR83Q-B excels in several key areas. The 240Hz refresh rate paired with sub-1ms input lag creates a responsive gaming experience. Colors look accurate and vibrant straight from the factory. The 100% sRGB and 90% DCI-P3 coverage puts it ahead of many competitors.

The HDMI 2.1 connectivity is a standout feature. It opens the monitor to console gamers at full QHD resolution and high refresh rates. The USB hub functionality adds convenience. The sturdy, fully adjustable stand with portrait mode support adds practical value.

Price-to-performance ratio is arguably this monitor’s greatest strength. At current street prices around $300, it delivers flagship-level gaming performance. The factory calibration saves you from needing an expensive colorimeter. Build quality and design remain solid throughout.

On the downside, HDR performance is limited by the edge-lit IPS panel. You will not get the deep blacks and dramatic contrast that local dimming or OLED panels provide. The 960:1 contrast ratio can make dark scenes look a bit flat, especially in dimly lit rooms.

The lack of built-in speakers may bother some users, though most gamers use external audio. Some users have reported noticeable IPS glow in the corners during dark scenes. This is common with IPS technology and varies between individual units.

Overall, the pros heavily outweigh the cons for this monitor. The limitations are typical of IPS panels at this price and are not specific flaws of this model.
