Overview
The ASUS XG27JCG is a flagship 27‑inch 5K gaming monitor that packs virtually every premium video‑processing technology currently available. Tom’s Hardware’s expert reviewer, Christian Eberle, spent extensive time testing the panel to verify its claims of ultra‑smooth motion and low input lag.
Key Features
- Adaptive‑Sync support for both NVIDIA G‑Sync and AMD FreeSync
- Dual‑refresh options: 120 Hz or 330 Hz native, with 180 Hz in 5K mode
- ELMB Sync and ELMB 2 blur‑reduction technologies
- Variable overdrive for dynamic response‑time control
- HDR support with three fixed picture modes and an Adjustable HDR toggle
Image & Color Settings
The Image menu provides comprehensive luminance controls, dynamic dimming, and three HDR modes. Enabling Adjustable HDR reveals a brightness slider for fine‑tuning.
In the Color menu you’ll find:
- Color temperature and gamma presets
- RGB sliders for precise grayscale tracking
- Selectable color spaces (sRGB, Adobe RGB, etc.) – choosing sRGB here preserves full calibration control.
HDR & Dynamic Dimming
When HDR content is detected, the XG27JCG automatically switches to one of three fixed HDR picture modes. The Adjustable HDR toggle adds brightness and contrast sliders for personal preference.
Dynamic Dimming remains active at all times and should stay on for maximum HDR impact.
Quick Access & Memory Settings
Two programmable control keys can be assigned to shortcuts such as Frame Rate Boost or GamePlus. Additionally, the monitor offers two memory slots, allowing you to save and recall custom configurations instantly.
