Product Overview

The LG 27GS95QE-B is a 27-inch WQHD (2560×1440) OLED gaming monitor with a 240Hz refresh rate and 0.03ms response time. It delivers deep blacks and vibrant colors thanks to its OLED panel and DisplayHDR True Black 400 certification. Whether you play fast-paced shooters or immersive RPGs, this monitor offers a smooth, responsive experience.

Key Features

  • 27-inch WQHD OLED panel (2560×1440) — pixel density of about 109 ppi, providing sharp text and a good balance between gaming and desktop use.
  • 240Hz refresh rate & 0.03ms response time — virtually no motion blur, giving you a competitive edge in fast-moving titles.
  • DisplayHDR True Black 400 — infinite contrast ratio from OLED ensures accurate detail in dark scenes.
  • NVIDIA G-SYNC Compatible & AMD FreeSync Premium Pro — supports variable refresh rate from both GPU vendors, preventing tearing and stuttering.
  • Fully adjustable stand (height, tilt, swivel, pivot) — comfortable ergonomics for long sessions.

Compatibility Guide

  • Video inputs: DisplayPort 1.4 (with DSC) ×1, HDMI 2.1 ×2. Works with PS5 and Xbox Series X at 4K downscaled or native WQHD 240Hz.
  • VESA mount: 100×100mm compatible, allowing you to use third-party arms or stands.
  • USB hub: 2× USB 3.0 Type-A and a headphone jack, helping keep your desk tidy.
  • Built-in speakers are limited; pairing with a gaming headset or external speakers is recommended.

Ideal Build Scenarios

  • Mid-high to high-end gaming PCs (e.g., RTX 4070 Super or higher, Ryzen 7 7800X3D or higher) to fully leverage WQHD 240Hz for ultra-smooth gameplay.
  • Competitive gamers who play FPS, racing, or other fast-paced titles where low latency and high refresh rates matter.
  • Users who also watch movies or do creative work, valuing both color accuracy and response speed.

Upgrade Considerations

  • To drive WQHD at 240Hz in demanding AAA titles, a GPU of at least RTX 4070 Ti Super or RX 7900 XT class is recommended.
  • HDMI 2.1 provides sufficient bandwidth, but DisplayPort 1.4 requires DSC (Display Stream Compression) for 240Hz. Ensure your GPU and cable support DP 1.4 with DSC.
  • OLED burn-in risk: enable pixel shift, auto brightness, and hide the taskbar to prevent static UI elements from causing permanent image retention.
  • If using a monitor arm, check the weight (approx. 4.2 kg without stand) and VESA compatibility beforehand.
