The perennial conflict between ultra-high resolution and blistering frame rates forces a compromise most gamers are all too familiar with. LG’s 27G810A-B Ultragear monitor presents a novel solution: a 27-inch panel with a dual-native mode that effectively toggles between a 4K UHD (3840 x 2160) panel at 180Hz and an FHD (1920 x 1080) configuration at 360Hz. This technical implementation, now available at a 42% discount bringing the price to $349.99, transforms the display from a niche multi-use peripheral into a compelling mainstream contender.
Beyond its headline-grabbing resolution flexibility, the 27G810A-B is engineered as a connectivity hub for next-generation systems. It features dual HDMI 2.1 ports and a DisplayPort 1.4 interface, ensuring compatibility with the latest consoles and graphics cards. The integration of DTS Headphone:X for spatial audio and VESA DisplayHDR 400 certification further rounds out its feature set, targeting both immersive single-player experiences and competitive esports. This price shift necessitates a detailed technical evaluation of its operational parameters and market positioning.
Deconstructing the 27G810A-B’s Dual-Mode Architecture
The core innovation of the LG 27G810A-B lies in its dual-mode functionality, a hardware-level feature that transcends simple resolution scaling. When operating in its native 4K mode at 180Hz, the monitor leverages its full pixel density for content creation, photo editing, and visually dense open-world games where detail is paramount. Switching to its FHD 360Hz mode is not merely a software downscale; it optimizes the panel’s drive circuitry for minimal signal processing latency, targeting competitive titles like Counter-Strike 2 and Valorant where every millisecond of pixel response and input lag is critical.
This bifurcated approach eliminates the traditional need for a dual-monitor setup comprising a high-resolution productivity screen and a dedicated high-refresh-rate gaming panel. The technical implication is significant: users gain access to two specialized display profiles from a single hardware unit, reducing desk clutter, cable management complexity, and overall system cost. The 1ms Gray-to-Gray (GtG) response time, coupled with support for both NVIDIA G-Sync Compatible and AMD FreeSync Premium, ensures that performance is maintained without introducing screen tearing or stuttering across both operational modes, provided the host system can deliver the requisite frame rates.
Competitive Toolkit: Crosshair, Black Stabilizer, and Dynamic Action Sync
LG equips the Ultragear series with a suite of software-driven features designed to provide tangible in-game advantages. The On-Screen Crosshair function overlays a static or customizable reticle at the screen’s center, independent of the game’s weapon model. This is particularly useful in titles where default crosshairs may be difficult to see or during weapon recoil patterns that obscure aim points. The Black Stabilizer feature dynamically brightens dark areas of the game scene without over-exposing brighter sections, a form of localized contrast adjustment that can reveal enemies lurking in shadows—a common tactical advantage in battle royale and tactical shooter environments.
Dynamic Action Sync (DAS) is LG’s terminology for a low input lag mode. When enabled, it minimizes the processing latency between the graphics card’s output signal and the pixels illuminating on-screen. For competitive gaming, this reduces the delay between a player’s mouse click and the corresponding action appearing in the game world. It is crucial to understand that these features, while beneficial, are post-processing effects. Enabling them may introduce minor artifacts or slightly increase GPU load, and they should be tested on a per-title basis to ensure they do not conflict with anti-cheat software or in-game settings.
Audio and Connectivity: The DTS:X and HDMI 2.1 Ecosystem
The audio implementation on the 27G810A-B moves beyond basic stereo output. The inclusion of a 4-pole headphone jack and DTS Headphone:X processing aims to deliver spatial, object-based audio. This technology creates a virtualized 3D soundscape from standard stereo game audio, simulating placement and movement of sounds like footsteps, gunfire, and environmental cues. For competitive play, accurate audio positioning can mean the difference between anticipating a flank and being caught unprepared. The monitor thus acts as an audio processing hub, reducing dependency on external sound cards or specialized gaming headsets with built-in virtual surround sound.
The connectivity suite is architected for future-proofing. The dual HDMI 2.1 ports support the full 48Gbps bandwidth, enabling 4K at 120Hz with HDR on next-gen consoles like the PlayStation 5 and Xbox Series X, or high-refresh-rate 4K from compatible GPUs. The DisplayPort 1.4 connection, using Display Stream Compression (DSC), is necessary to achieve the monitor’s maximum 4K 180Hz specification. This combination ensures the display will not become a bottleneck for new hardware releases over the next several product cycles, protecting the user’s investment.

The $349.99 Price Point and Competing Monitor Landscape
The 42% discount, placing the LG 27G810A-B at $349.99, dramatically alters its value proposition. At this price, it enters a fiercely competitive segment where it must contend with dedicated 1440p high-refresh-rate monitors and entry-level 4K 144Hz displays. Its primary advantage is its operational duality; no competitor at this price offers a native switch between a high-fidelity 4K 180Hz experience and an esports-ready 360Hz FHD mode. This makes it a uniquely flexible tool for hybrid users who refuse to specialize.
However, the market context is critical. Alternatives like the MSI MPG 321URX offer superior OLED picture quality and higher HDR performance, while monitors like the Samsung Odyssey OLED G9 provide an immersive super-ultrawide format. The AOC Q27G3XMN brings Mini-LED backlighting with superior HDR 1000 brightness at a similar screen size. The 27G810A-B’s concessions are its use of a standard IPS panel with limited HDR 400 peak brightness and a 27-inch diagonal that some users may find restrictive for multi-window productivity. The discount, therefore, is a strategic move to offset these inherent limitations by emphasizing unparalleled mode-switching versatility.
Technical Verdict on the LG Ultragear’s Strategic Discount
LG’s aggressive pricing on the 27G810A-B Ultragear is more than a promotional sale; it is a market correction that aligns the monitor’s cost with its technological niche. The dual-mode feature is an innovative engineering solution to a genuine user workflow problem, but its value was previously obscured by a premium price tag. At $349.99, the calculus changes. The monitor presents a compelling, cost-effective alternative to managing two separate displays, while its robust HDMI 2.1 and adaptive sync support guarantee compatibility across gaming ecosystems.
The target user is clearly defined: the gamer who demands both cinematic immersion and competitive edge, the content creator who needs color-accurate 4K space but also enjoys high-refresh-rate gaming, and the system builder seeking to maximize functionality without expanding their physical desktop footprint. For these users, the discounted LG 27G810A-B transitions from an interesting novelty to a rationally justifiable purchase. It represents a specific, technically adept answer to the resolution-versus-refresh-rate dilemma, making its newly reduced price a significant catalyst for adoption.
