Asus quietly lists 5K 180Hz dual-mode XG27JCG monitor

Asus has updated its website with a new high-end display that pushes pixel density to the extreme. The ROG Strix XG27JCG is a 27-inch monitor boasting a massive 5K (5120 x 2880) resolution and a 180Hz refresh rate. Most interestingly, it features a dual-mode function that lets users drop to 1440p to unlock a 330 Hz refresh rate for competitive gaming.

Asus footnotes indicate that to run the ROG Strix XG27JCG at its native 5K 180 Hz, users will strictly require an Nvidia RTX 50-series or AMD RX 7600 (or higher) GPU. This requirement appears to stem from bandwidth limitations; while the RTX 40-series relies on DisplayPort 1.4a, the newer recommended cards support DisplayPort 2.1. It seems Asus has implemented this restriction to ensure stability, as older standards, even with DSC, may struggle with the bandwidth required for 5K at such high refresh rates.

Specification-wise, the XG27JCG uses a Fast IPS panel with a 0.3 ms G2G response time and a 218 PPI density, making individual pixels virtually indistinguishable at normal viewing distances. While it lacks local dimming, it carries an HDR600 certification and 97% DCI-P3 colour coverage. For motion clarity, it supports ELMB 2 and ELMB Sync, allowing backlight strobing to work alongside VRR (G-Sync/FreeSync) to minimise blur.

Other nice features included DisplayWidget Center, various gaming AI features like Dynamic Crosshair (automatically contrasts with the background), Dynamic Shadow Boost (brightens dark areas), and AI Visual (automatically adjusts settings based on the content). Connectivity includes one DisplayPort 1.4, two HDMI 2.1 ports, and USB-C with 15W power delivery. Currently listed in Hong Kong for HKD$6,500 (£625), we expect a formal global debut at CES 2026.

KitGuru says: A 5K resolution at 180 Hz in a 27-inch monitor should be an incredible visual experience. However, to drive such a combination of frequency and resolution, you'll need quite a system.
