Design and Build
The LG 27G810A-B.AUS sports a sleek, modern design consistent with LG’s UltraGear lineup. It features a narrow bezel that maximizes screen real estate and contributes to a cleaner multi-monitor setup if desired. The stand is a central point of the design, offering a full range of ergonomic adjustments including height, tilt, swivel, and pivot control. This allows users to find an optimal viewing angle for comfort during long gaming sessions, a feature appreciated by both casual and competitive gamers. The monitor’s overall build quality, as suggested by the specifications, is designed to support a “battlestation upgrade” with a focus on both performance and adjustable style.
The matte screen finish is a practical choice, helping to reduce glare and reflections from ambient lighting. With dimensions of 8.7″D x 24.2″W x 21″H and a weight of 16.3 pounds, it has a substantial desktop presence. The included components, such as DisplayPort and HDMI 2.1 cables, indicate LG’s intention to get users connected and gaming quickly with next-gen consoles and PCs right out of the box. The design prioritizes function and adjustability, aiming to cater to the ergonomic needs of dedicated gamers.
Performance and Features
Core Display Performance
The heart of the LG 27G810A-B.AUS is its 27-inch IPS panel with a native 4K UHD (3840 x 2160) resolution. This delivers a high pixel density for sharp, detailed imagery, beneficial for both gaming and general productivity. The panel boasts up to 95% DCI-P3 color coverage, which suggests vibrant and saturated colors suitable for gaming and media consumption. Combined with VESA DisplayHDR 400 certification, the monitor is capable of enhanced contrast and brighter highlights compared to standard dynamic range, though it’s important to note this is an entry-level HDR tier. The 1ms Gray-to-Gray (GtG) response time is a key specification for gaming, aiming to minimize motion blur and ghosting during fast-paced action, keeping gameplay crisp.
The Dual Mode Advantage
The standout feature is the Dual Mode. With a hotkey, users can switch between two preset configurations: native 4K UHD resolution at a refresh rate of up to 180Hz, or a downscaled Full HD (1920×1080) resolution at an extremely high 360Hz refresh rate. This is designed to give users control over their experience based on the game. The 4K 180Hz mode is intended for visually stunning, story-driven games where detail and immersion are paramount. The Full HD 360Hz mode is tailored for competitive esports titles like FPS and MOBA games, where maximum frame rate and responsiveness can provide a tangible advantage. This flexibility is the monitor’s primary selling point.
Sync Technologies and Gaming Enhancements
To ensure smooth gameplay across both modes, the monitor supports both AMD FreeSync Premium and NVIDIA G-SYNC compatibility. These adaptive sync technologies work to eliminate screen tearing and stuttering by synchronizing the monitor’s refresh rate with the graphics card’s frame output. This is crucial for a fluid experience, especially when frame rates fluctuate. LG includes several gaming-specific software features: Dynamic Action Sync aims to reduce input lag, Black Stabilizer brightens dark scenes to reveal hidden enemies, and an on-screen Crosshair overlay can aid aiming precision in shooters. These tools are common in gaming monitors and add value for competitive players.
Connectivity and Audio
Connectivity is robust, featuring dual HDMI 2.1 ports and a DisplayPort 1.4 input. HDMI 2.1 is essential for supporting high bandwidth signals from next-generation gaming consoles and modern PCs to achieve the advertised high refresh rates at 4K. The monitor also includes a USB hub with upstream and downstream ports for peripheral connectivity. On the audio front, LG incorporates DTS HP:X technology for spatial sound processing through headphones, and a unique 4-pole headphone jack that combines stereo audio and microphone input into a single connection, simplifying cable management for gaming headsets.
Setup, Support and Ownership
Setup should be straightforward, with the necessary power, DisplayPort, and HDMI 2.1 cables included in the box. The fully adjustable stand makes it easy to achieve an ergonomic position without requiring a separate VESA mount, though the monitor is presumably compatible with standard mounts if desired. Achieving the full 4K 180Hz or FHD 360Hz performance requires a compatible graphics card that supports DisplayPort 1.4 or HDMI 2.1, a significant consideration for PC gamers. The manufacturer provides a standard one-year warranty. As a newer model, long-term reliability data and extensive user feedback are not yet available, which is a typical consideration for early adopters.
What Owners Say
As a recently released product, there are no detailed buyer review excerpts available at this time. The overall rating provided by the manufacturer is high, but prospective buyers should seek out initial user impressions and professional reviews as they become available to gauge real-world performance, build quality, and the practical utility of features like the Dual Mode switch.

Who Should Buy It (and Who Should Skip It)
The LG 27G810A-B.AUS is ideally suited for the multi-genre gamer. If your time is split between exploring vast, detailed open-world games and jumping into fast-paced competitive matches, the Dual Mode offers a compelling, all-in-one solution. It’s also a great fit for gamers who use a single monitor for both high-fidelity gaming and productivity, benefiting from the sharp 4K resolution for work. Owners of next-gen consoles like the PlayStation 5 and Xbox Series X, which support high refresh rates, will appreciate the HDMI 2.1 connectivity.
This monitor is less ideal for gamers who have already dedicated their setup to a single discipline. A pure competitive esports player might prefer a larger, native 240Hz or 360Hz monitor, while a dedicated single-player enthusiast might opt for a larger 4K screen or one with more advanced HDR. Users with older graphics hardware that cannot drive 4K at high frame rates may not fully utilize the monitor’s capabilities. For those seeking the most immersive wide-screen experiences, exploring dedicated ultra-wide monitors might be a better path.
Final Verdict
The LG 27G810A-B.AUS successfully carves out a niche with its innovative Dual Mode feature. It doesn’t force a choice between high resolution and high refresh rate; instead, it offers a legitimate toggle between two optimized states. The core specifications are solid: a sharp 4K IPS panel with good color, fast response time, comprehensive adaptive sync support, and future-proofed connectivity. The inclusion of gaming utilities and a fully adjustable stand rounds out a well-considered package aimed squarely at the enthusiast gamer who refuses to be pigeonholed.
However, this versatility comes with prerequisites. To unlock its full potential, you need a powerful gaming PC or next-gen console. The 27-inch size, while standard, might leave some desiring more screen real estate for 4K immersion. As a new product, its long-term reliability remains to be seen. For the right user—one with the hardware to support it and a diverse gaming habit—the LG 27G810A-B.AUS is a compelling and unique offering that effectively bridges two major gaming camps. It stands as a strong option in the monitor market for those who want top-tier performance across multiple genres without maintaining two separate displays.
FAQs
What graphics card do I need for the LG 27G810A-B.AUS?
To utilize the monitor’s full capabilities, you need a graphics card that supports DisplayPort 1.4 or HDMI 2.1. For gaming at 4K resolution with a high refresh rate (up to 180Hz), a high-end current-generation GPU from NVIDIA or AMD is typically required. The specific model needed depends on the game and desired graphics settings. The monitor’s Dual Mode also means a powerful card is needed to drive the 4K mode effectively.
How does the Dual Mode work?
The Dual Mode is activated via a hotkey on the monitor. One mode sets the display to its native 4K UHD (3840×2160) resolution with a refresh rate up to 180Hz, ideal for visually detailed games. The other mode switches the display to a Full HD (1920×1080) resolution with a refresh rate up to 360Hz, optimized for fast-paced competitive games where maximum frame rate is critical. You manually select the mode based on the game you are playing.
Is this monitor good for console gaming?
Yes, it is well-suited for modern consoles like the PlayStation 5 and Xbox Series X/S, thanks to its two HDMI 2.1 ports. HDMI 2.1 supports the high bandwidth needed for 4K at 120Hz, which these consoles can output for supported games. The monitor’s 4K resolution, HDR support, and adaptive sync technologies will provide a high-quality console gaming experience, though it will not use the full 180Hz refresh rate in 4K due to console limitations.
Does the LG 27G810A-B.AUS have good color accuracy for creative work?
The monitor features an IPS panel with up to 95% DCI-P3 color gamut coverage, which indicates a wide and vibrant color range suitable for content consumption and some level of creative work. However, the manufacturer does not list specific color accuracy metrics like Delta-E or factory calibration data. For professional color-critical work, users specializing in tech gear for creative fields might seek monitors with more detailed color specifications and calibration reports.
