Overview
On paper the Asus ROG Strix OLED XG27ACDNG reads as a compact flagship: 360 Hz on a 26.5-inch QD-OLED at 2560 x 1440. The 26.5-inch panel combines 2560 x 1440 resolution, a 0.03 ms GtG claim and a 48–360 Hz range. FreeSync Premium Pro, G-Sync Compatible and VESA AdaptiveSync Display 360Hz are all listed. Typical brightness is 250 cd/m² against a 1,000 cd/m² peak, so the peak should be treated as an HDR highlight figure rather than normal full-screen output. At 26.5 inches the 2560 x 1440 panel works out near 110 PPI, so it is built for frame rate rather than desktop text. Buy it if 360 Hz QD-OLED and 90 W USB-C suit a premium desk; skip it if built-in audio or high sustained brightness is required.

HDR & Brightness Reality
The self-emissive QD-OLED (Samsung) panel gives the DisplayHDR 400 True Black / HDR10 badge a stronger basis than a basic edge-lit LCD. The sheet lists 1000 cd/m² peak brightness and 1500000 : 1 contrast, but typical brightness is only 250 cd/m². That large gap means the peak should be treated as a highlight claim, not constant full-screen output. No test-window size or sustained-brightness result is published.
