LG has added another OLED model to its growing UltraGear OLED lineup with the UltraGear 27GX704A, following the earlier 27GX700A. The main difference between these two models is the OLED technology used. The UltraGear 27GX700A uses Tandem OLED technology (4th gen WOLED), while the UltraGear 27GX704A relies on older 2nd Gen WOLED technology.

Second-gen WOLED monitors use white OLED emitters with color filters to produce RGB colors, offering good efficiency and lower burn-in risk but slightly reduced brightness and color purity. RGB Tandem OLED monitors use separate red, green, and blue emitters stacked together, delivering higher brightness, better color accuracy, and longer lifespan by spreading the electrical load across multiple layers.

The 27GX704A monitor is available on Amazon for US$779. This monitor was initially introduced in China, Japan and Canada last month.

The UltraGear 27GX704A uses a 26.5-inch glossy WOLED panel with a QHD resolution of 2560×1440 and a 16:9 aspect ratio. It offers 178-degree viewing angles to keep image quality consistent from all sides. The monitor supports a 240Hz refresh rate and a 0.03ms grey-to-grey response time, allowing smooth visuals during fast-moving gameplay.

The display covers 98.5 percent of the DCI-P3 color gamut, supports 10-bit color depth, and has a 1,500,000:1 static contrast ratio. It delivers 275 nits of typical brightness and reaches up to 1300 nits in HDR mode. It is certified for VESA DisplayHDR 400 True Black and HDR10, providing strong contrast and bright highlights.

For adaptive sync, it supports AMD FreeSync Premium Pro, NVIDIA G-Sync compatibility, and VESA AdaptiveSync. Gaming features include Black Stabilizer, Dynamic Action Sync, crosshair overlays, FPS counter, factory calibration, flicker-free technology, and reader mode.

In terms of connectivity, the 27GX704A comes with two HDMI 2.1 ports, one DisplayPort 1.4, a USB-B upstream port, two USB-A downstream ports, and a 3.5mm four-pole headset jack.

The design features a four-sided borderless frame with a glossy finish and Hexagon RGB lighting on the back. The stand supports 130mm height adjustment, as well as swivel, tilt, and pivot functions. The monitor measures 605.2 × 351 × 45.3 mm without the stand and weighs 4.8 kg.
