ASUS ROG Strix 27 4K HDR USB-C Gaming Monitor - High-Refresh 4K

In this review of the ASUS ROG Strix 27 4K HDR USB-C Gaming Monitor, the bottom line is simple: this display is for serious gamers and creators who want a sharp 27-in 4K image with very high refresh flexibility. The monitor's standout capability is the dual-mode refresh - true 4K at up to 160 Hz or an FHD mode at up to 320 Hz - which delivers smooth motion without sacrificing resolution when performance matters. For anyone prioritizing fast response, color fidelity and a responsive experience, this monitor earns attention.

Key Features

• 4K at high refresh: The display supports 3840 x 2160 at up to 160 Hz, which gives a crisp, detailed image while still keeping frame delivery smooth for modern titles.
• Dual-mode flexibility: Switch to an FHD mode that can reach up to 320 Hz when competitive, high-frame-rate play is needed without changing monitors.
• Fast IPS with 1 ms response: ASUS Fast IPS technology provides a 1 ms GTG response time to minimize motion blur and preserve clarity during fast scenes.
• ELMB SYNC: Extreme Low Motion Blur Sync lets ELMB run together with variable refresh rate, reducing both ghosting and tearing for cleaner high-frame gameplay.
• Sturdy ergo arm support: The included ROG Ergo Monitor Arm handles broad compatibility and full motion adjustments for an optimal ergonomic setup.
• Easy, reliable installation: The arm and monitor interface are designed for quick setup and were durability tested over 10,000 motion cycles for long-term reliability.

Who It's For

The ASUS ROG Strix 27 4K is best for PC gamers who want a premium 4K panel without sacrificing high refresh capabilities, and for content creators who need accurate color and sharp resolution for editing or review work. Users with powerful GPUs who can drive high frame rates will especially appreciate the dual-mode refresh options and the quick GTG response.

Those who should look elsewhere include buyers on a tight budget or casual users who do not need high refresh or 4K resolution. Also, players who require extreme brightness above typical gaming panels may find screen brightness a mixed point based on some user feedback.
