LG's UltraGear 27GX704A is a new 26.5-inch WOLED gaming monitor with QHD resolution at 240 Hz, 0.03 ms response time, HDR400/HDR10, a wide color gamut, and adaptive sync tech.

LG has launched the UltraGear 27GX704A, a 26.5-inch WOLED gaming monitor with a resolution of 2560 x 1440 pixels. The display features a 240 Hz refresh rate and a low 0.03 ms grey-to-grey response time. Its OLED panel supports 10-bit colors, and covers 98.5% of the DCI-P3 color gamut. The static contrast ratio is 1,500,000:1. Brightness is rated at 275 cd/m² typically, with a peak brightness of up to 1300 cd/m² for highlights. HDR support is included with DisplayHDR 400 True Black and HDR10 certification.

The monitor has a glossy coating and includes LG's META Technology 2.0 and Micro Lens Array+. The monitor uses LG's 3rd Generation (Gen. 3) WOLED panel - commonly known as a 3-stack design. The 27GX704A has a 4-side virtually borderless design, and connectivity options consist of two HDMI 2.1 ports, one DisplayPort 1.4, USB Type-B upstream and USB Type-A downstream ports, and a 3.5 mm audio jack that supports sound and microphone input. The device supports AMD FreeSync Premium Pro and is Nvidia G-Sync compatible. You can access the on-screen settings using a joystick, present beneath the central region of the bottom bezel.

Additional features include factory and hardware calibration, flicker-free technology, FPS counter, black stabilizer, RGB ambient lighting, reader mode, and several gaming-oriented settings such as crosshair overlays and dynamic action sync. The monitor weighs 4.8 kg witohut the stand and measures approximately 605.2 x 351 x 45.3 mm (W x H x D). Included accessories are a DisplayPort cable, HDMI cable, and USB Type-A to Type-B cable.

WOLED is different from traditional RGB OLED in that it uses white OLED emitters combined with RGB color filters, meaning greater panel efficiency and higher brightness potential. Gen. 4 panels (not found here) use a tandem RGB configuration and achieve still better HDR certifications, such as DisplayHDR 500 True Black.

As of writing, the monitor is officially listed on only LG's Japan website. Pricing and availability details are undisclosed.
