What we like about this LG UltraGear 27GX700A-B monitor

Fourth-generation OLED with Primary RGB Tandem technology

The LG UltraGear 27GX700A-B uses LG’s fourth-generation OLED technology with a Primary RGB Tandem structure, designed to improve brightness while retaining the exceptionally deep blacks and per-pixel illumination associated with OLED. LG quotes peak brightness of up to 1,500 nits under certain conditions, while enhanced APL and reduced ABL are intended to maintain stronger brightness across larger portions of the screen.

Color reproduction is another strength. LG specifies up to 99.5% DCI-P3 gamut coverage, providing a substantially wider color range than standard sRGB displays. UL verification for Perfect Color, 100% Color Fidelity, Perfect Reproduction, and Perfect Black further supports the panel’s credentials for accurate image reproduction.

280Hz refresh rate and 0.03ms response time

A maximum 280Hz refresh rate makes the 27GX700A-B particularly well suited to competitive gaming, while the quoted 0.03ms GtG response time takes advantage of OLED’s extremely fast pixel transitions. Combined, these specifications should produce exceptionally clear motion with minimal ghosting, making the monitor particularly attractive for fast-paced FPS and esports titles.

Excellent HDR and contrast performance

OLED’s self-emissive pixels allow individual areas of the image to switch completely off, producing essentially perfect blacks and a quoted 1,500,000:1 contrast ratio. The monitor also carries VESA DisplayHDR True Black 500 certification, providing greater dynamic range and considerably more convincing dark-scene performance than conventional LCD gaming monitors.

Wide DCI-P3 color coverage

LG specifies up to 99.5% coverage of the DCI-P3 color gamut, while the panel has also received UL verification for Perfect Black, Perfect Color with 100% Color Fidelity, and Perfect Reproduction. This combination gives the monitor strong credentials for visually demanding games while also making it suitable for photo, video, and other color-sensitive creative workloads.

G-SYNC and FreeSync support

NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro support allow the monitor’s refresh rate to synchronize dynamically with output from compatible graphics cards. This reduces tearing and stuttering when frame rates fluctuate, helping the 280Hz OLED panel maintain smooth and responsive motion across a wide performance range.

Who’s should buy this 280Hz OLED gaming monitor deal?

The LG UltraGear 27GX700A-B is aimed primarily at enthusiast and competitive PC gamers who want OLED image quality without sacrificing the refresh rates normally associated with esports monitors. Its 2560×1440 resolution is particularly well suited to the 26.5-inch panel size, providing good pixel density while requiring substantially less GPU processing power than 4K. That makes reaching the monitor’s 280Hz ceiling considerably more realistic with a high-end graphics card, especially in competitive games such as Counter-Strike 2, Valorant, Overwatch 2, and similar titles. The combination of excellent contrast, wide DCI-P3 coverage, strong HDR capabilities, and accurate color reproduction also makes it appealing to users splitting their time between gaming and creative work.
