Overview
At its core, the ASUS ROG Strix XG279CNS uses an IPS panel offering 1920 x 1080 pixels / Full HD / 1080p and a 48 Hz - 380 Hz / DisplayPort - 470 kHz - 470 kHz; 48 Hz - 380 Hz / HDMI - 27 kHz - 404 kHz; 48 Hz - 360 Hz refresh range. On motion, the panel is rated 1 ms GtG and 0.3 ms (MPRT) MPRT; GtG and MPRT use different test methods, so treat them separately. For picture quality, expect 400 cd/m² typical brightness, 1000 : 1 contrast and 110 % sRGB coverage. On the sync side, FreeSync, G-Sync, VESA AdaptiveSync Display 380Hz is supported. On connectivity, you get 1x HDMI 2.1, 1x DisplayPort 1.4.

HDR & Brightness Reality
The DisplayHDR 400 label is not persuasive on these figures. Typical brightness and peak brightness are both listed at 400 cd/m², so the sheet provides no extra headroom for HDR highlights. The 1,000:1 contrast ratio is ordinary for IPS, and no local dimming is stated. HDR content can be accepted, but the hardware description points to basic signal support rather than a visibly expanded luminance range.
