LG 27GX704A-B Is a 27-Inch 1440p 360Hz OLED Gaming Monitor That Hits $699 on Sale

What it is

The LG 27GX704A-B is LG’s 2026 mid-tier OLED gaming monitor, positioned below the flagship 27GS95QE and targeting competitive gamers who want OLED color and response time without the QD-OLED premium. Core specs: 27-inch WOLED panel at 2560x1440 resolution, 360 Hz native refresh rate, 0.03ms gray-to-gray response time, 1,300 nits HDR peak brightness (TrueBlack 400 certification), 99% DCI-P3 color gamut, NVIDIA G-Sync compatibility (no standalone G-Sync module), AMD FreeSync Premium Pro, DisplayPort 2.1 with DSC support for 4K-passthrough scenarios, USB-C with 90W power delivery for laptop docking, dual HDMI 2.1, two USB-A 3.0 ports, ergonomic stand with tilt/swivel/height/pivot, VESA 100x100, and LG’s OLED Care suite (auto-screen-shift, pixel refresh).

Pricing: $799 MSRP at LG.com; $699 current sale at Best Buy and Amazon.

What’s interesting

RTINGS’ review ranked the 27GX704A-B in their top tier for 27-inch competitive gaming monitors. The combination of 1440p resolution, 360 Hz refresh, and OLED panel is the sweet spot for esports: 1440p’s pixel density beats 1080p for clarity while remaining drivable by RTX 4070 / RX 7800 XT class GPUs at high frame rates.

OLED 0.03ms response time eliminates motion blur that LCD gaming monitors (even 240 Hz IPS) cannot match. For competitive shooters (Counter-Strike 2, Valorant, Overwatch), the visual edge in target tracking is meaningful.

1,300 nits HDR peak makes HDR content genuinely usable for non-darkroom viewing. RTINGS measured real-world HDR performance as best-in-class for OLED monitors at this size and resolution.

USB-C with 90W power delivery handles MacBook Pro 14-inch (96W) charging plus video signal in a single cable. For users who dock a laptop at the same desk as the gaming PC, single-cable handoff is the daily-use win.

DisplayPort 2.1 with DSC is the future-proofing spec. Current GPUs don’t saturate DP 2.1 bandwidth, but the connector covers the next generation’s requirements.

LG’s OLED Care features (auto-pixel-shift, scheduled pixel refresh, screen saver auto-trigger) address burn-in concerns. RTINGS’ long-term testing showed no burn-in after 6 months of mixed-use ownership.

What’s missing or unverified

WOLED panels still suffer from text fringing on subpixel layouts. macOS users and code editors with small fonts may see minor color fringing on white-on-black text. QD-OLED competitors (Alienware AW2725DF) avoid this issue.

1,300 nits peak is for HDR small-window content. Full-screen sustained brightness drops to roughly 250 nits, lower than LCD competitors at 400 nits. For bright-room daytime use, the 27GX704A-B can feel dim.

Burn-in risk on OLED is real over multi-year ownership, especially with static UI elements (taskbar, game HUDs). LG’s OLED Care helps but doesn’t eliminate the risk. 2-year warranty includes burn-in coverage.

No KVM functionality. Multi-PC users who want one keyboard/mouse switching between two computers via the monitor need a separate KVM switch.

Built-in speakers are absent. Most gaming monitor buyers run external audio anyway.

Stand is functional but plain. Premium gaming monitor competitors include RGB stands and cable management; LG keeps the design minimal.

Against Alienware AW2725DF at $899 (QD-OLED, less text fringing), Samsung Odyssey OLED G6 at $999 (QD-OLED, larger 27-inch), and LG 27GR95QE at $799 (older, 240 Hz), the 27GX704A-B at $699 wins on price-per-feature; it loses on text rendering versus QD-OLED competitors.

Who it’s for

Competitive 1440p gamers who want OLED motion clarity at $699. PC gamers running RTX 4070 / RX 7800 XT class GPUs that drive 1440p at 240+ fps in supported titles. Hybrid users who appreciate the USB-C 90W laptop-docking option for content creation off-shift. Esports enthusiasts upgrading from 240 Hz LCD setups.

Not for: heavy text users (subpixel fringing), bright-room workstation users (sustained brightness too low), 4K resolution buyers (this is 1440p), or buyers who can’t accept burn-in risk.

Verdict

The LG 27GX704A-B at $699 sale is the right pick for 1440p competitive gamers who want OLED panel quality at sub-$700. 360 Hz refresh plus 0.03ms response plus 1,300 nits HDR plus USB-C 90W delivery is a feature stack that justifies the price. Against Alienware AW2725DF, Samsung Odyssey OLED G6, and LG 27GR95QE, this monitor wins on price-per-feature; it loses on text rendering. For target 1440p competitive gamers, this is the right pick.
