LG 27GX704A-B 27” OLED QHD Gaming Monitor
The LG 27GX704A-B is a 27-inch OLED gaming monitor built for competitive players who want ultra-fast response performance together with OLED HDR image quality and smooth 240Hz gameplay. Its 2560×1440 QHD resolution and flat 16:9 format make it especially suitable for FPS gaming where motion clarity and low latency matter.
The OLED panel delivers 0.03ms response time together with DisplayHDR 400 True Black certification, HDR10 support and 98.5% DCI-P3 colour coverage. Because OLED pixels illuminate individually instead of relying on traditional backlight zones, the monitor produces effectively infinite contrast behaviour with deeper blacks and cleaner HDR shadow detail than many IPS or VA gaming displays.
At 240Hz, the display refreshes every 4.2ms, helping movement appear smoother during competitive games such as Counter-Strike 2, Valorant and Apex Legends. Combined with G-SYNC Compatible, FreeSync Premium Pro and VESA Adaptive Sync support, the monitor is designed for low-latency gameplay across both NVIDIA and AMD GPU systems.
The glossy OLED panel additionally improves perceived contrast and colour vibrancy compared to many matte gaming displays, although reflections may become more noticeable in brightly lit rooms.
For connectivity, the LG 27GX704A-B includes 2× HDMI 2.1, DisplayPort 1.4 and headphone output support. The monitor does not include USB-C or an integrated USB hub, making it more focused on dedicated gaming setups.
The ergonomic stand supports height, tilt, swivel and pivot adjustment, while 100×100 mm VESA mounting allows use with a compatible monitor arm.
LG gaming features such as Black Stabilizer and FPS Counter are additionally included to help improve competitive gaming visibility and gameplay monitoring.
