Tandem QD-OLED — Stunning 4K Visuals

The 27-inch 4K QD-OLED panel delivers 1,500,000:1 contrast ratio, 99% DCI-P3 gamut, true 10-bit color, and Delta E < 2 color accuracy. VESA DisplayHDR 400 True Black compliance ensures breathtaking highlights and inky blacks.

DisplayWidget Center — Full Control

Powerful monitor management software allowing users to access OLED Care functions and adjust monitor settings with a mouse — no OSD navigation required. Offers firmware update notifications, direct update options, and configuration import/export for sharing [citation:14].

Pro Tip

Unlock Ultimate 4K OLED Gaming

Enable Uniform Brightness for consistent luminance levels during marathon gaming sessions. The Neo Proximity Sensor automatically detects when you step away and switches to a black screen to protect against burn-in. Use Aspect Ratio Control to simulate 24.5-inch 1080p mode for competitive esports.

OLED Care Pro — Neo Proximity Sensor

The built-in Neo Proximity Sensor precisely detects the user’s distance. When you step away, the monitor transitions to a black image to protect against panel burn-in. Detection distance is customizable via DisplayWidget Center for maximum convenience and protection [citation:1][citation:17].

Built to Last — 3-Year Burn-in Warranty

ROG OLED monitors are engineered for stunning visuals for years. An innovative custom heatsink and unique internal airflow design improve cooling and reduce burn-in risk. Comes with a 3-year warranty including panel burn-in [citation:8][citation:20].

Aspect Ratio Control — Competitive Edge

For competitive gamers more familiar with smaller 1080p monitors, the XG27UQDMS can be set to replicate a 24.5-inch panel in esports mode, as well as other visual modes including 4:3 and square equivalent [citation:14].
