Asus has updated its ROG Strix XG27UCS gaming monitor with a dual-mode feature enabling seamless switching between 4K@160Hz and 1080p@324Hz configurations, retaining core specs like the Fast IPS panel and adaptive sync while removing the stand's smartphone slot.

Asus has enhanced its popular ROG Strix XG27UCS gaming monitor with a notable upgrade that addresses diverse gaming needs. The refreshed XG27UCSR (Gen 2) model maintains the original's acclaimed 27-inch Fast IPS panel but introduces dual-mode functionality – allowing users to dynamically switch between resolution profiles based on their gameplay requirements. This practical evolution positions the monitor as a versatile tool for gamers balancing visual fidelity and performance.
Key Technical Specifications
- Panel: 27-inch Fast IPS with 3840x2160 (4K) native resolution
- Refresh Rates:
- 160Hz in 4K mode
- 324Hz in 1080p (FHD) mode
- Response Time: 0.3ms (GTG)
- Adaptive Sync: AMD FreeSync Premium Pro / NVIDIA G-Sync Compatible
- Motion Handling: ELMB (Extreme Low Motion Blur) sync with variable refresh rate
- Connectivity: HDMI 2.1, DisplayPort 1.4, USB-C with DP Alt Mode (90W Power Delivery)
- HDR: VESA DisplayHDR 400 certification

The dual-mode capability marks the most significant departure from the Gen 1 model. When switched to FHD mode, the monitor bypasses traditional upscaling by natively rendering 1920x1080 pixels across the same physical display area. Asus' Smart Pixel technology maintains clarity during this transition, ensuring sharp text and UI elements despite the lower resolution. This implementation provides tangible benefits: Competitive gamers gain ultra-smooth 324Hz responsiveness for titles like Valorant or CS2, while single-player experiences retain cinematic 4K detail at 160Hz.
