ASUS ROG Strix XG27UCS: 160Hz Refresh Rate and 1ms Response Time
A 4K monitor doesn’t have to be slow. The ASUS ROG Strix XG27UCS reaches 160Hz while its Fast IPS panel offers 1ms GtG. This setup reduces visible motion blur and smooths fast camera movements. Additionally, the 160Hz refresh rate gives players more fluid motion than a 60Hz display.
ELMB Sync & Adaptive Sync

This is especially helpful as the GPU’s frame rate varies in demanding games.
Color Performance
The XG27UCS isn’t positioned as a true color-monitor for professionals.
However, its color performance is strong for a gaming display.
ASUS specifies 95% DCI-P3 coverage and 130% sRGB color space, along with 10-bit color support.
That makes the monitor suitable for:
- Gaming

- General photo editing
- Video editing
- Social media creation
For professional color-critical workflows, we recommend a dedicated creator monitor with more specialized calibration and color-management features.
HDR Experience
The monitor supports HDR10 and VESA DisplayHDR 400. ASUS specifies up to 450 nits peak HDR brightness. HDR-compatible games can benefit from brighter highlights and improved tonal range compared with standard SDR. However, keep expectations realistic: DisplayHDR 400 is an entry-level HDR certification, so it won’t provide deep blacks and high contrast of OLED or advanced Mini LED displays.
HDMI 2.1 for Modern Gaming

us b-c Connectivity
us b-c makes the monitor particularly useful for laptop users. The us b-c port supports DisplayPort Alt Mode, allowing compatible laptops to send video to the monitor through us b-c. ASUS specifies 15W us b-c power delivery. Additionally, it’s important to note that the 15W charging capability is not intended to fully power most performance laptops. Instead, the key advantage is convenient video connectivity.

- Height adjustment up to 120mm
