The ASUS ROG Strix XG27UCGR is a 27-inch Fast IPS monitor for players who want 4K sharpness on a smaller desk without OLED care concerns. Dual mode runs at 4K and 162Hz or FHD and 485Hz, so the top refresh rate applies only at the lower resolution.

Who it is for: Players who want a capable 27-inch 4K high-refresh monitor without moving to OLED.

• Pick the panel type first. OLED gives per-pixel contrast and very fast response times, while IPS avoids burn-in concerns and suits long sessions with static windows.
• Match the refresh rate to your hardware. A 240Hz 4K monitor only pays off with a graphics card that can push high frame rates at 4K. Consoles and mid-range PCs are well served by 165Hz or 180Hz.
• Understand dual mode. Dual-mode monitors reach their highest refresh rates only at FHD, so treat the top number as an esports mode, not a 4K figure.
• Check the ports, not just the headline specs. Console players should count the HDMI 2.1 ports, and PC players with a DisplayPort 2.1 graphics card get the most from a DisplayPort 2.1 monitor.
• Read the HDR certification. DisplayHDR True Black 400 and 500 are OLED tiers, while DisplayHDR 400 on an IPS panel is an entry-level HDR rating.
• Look at USB-C power if you use a laptop. A 90W port can charge many laptops over one cable, while a 15W port is mainly for accessories.
