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.

Frequently Asked Questions
01 Why does the XG279CNS stay at Full HD despite its 27-inch size? +
The lower resolution makes very high frame rates easier to reach and supports the 380 Hz focus. The cost is low 81 PPI density, so text and fine detail will look less sharp than on QHD.
02 How should the combined 1 ms and 0.3 ms response entry be read? +
The sheet joins a 1 ms GtG claim and a 0.3 ms MPRT claim without spacing. They use different measurement methods and should not be treated as one identical result.
03 Does 7.5 W USB-C provide useful laptop charging? +
It can provide only light power and carry video through DisplayPort Alt Mode. It is not a replacement for a normal laptop power adapter.
04 Why is the HDR badge weak on this 380 Hz panel? +
Both typical and peak brightness are listed at 400 cd/m², leaving no stated highlight reserve. No local dimming or higher contrast technology is listed either.
05 Who benefits most from the 380 Hz refresh ceiling? +
Competitive players who can produce frame rates close to that level gain the clearest reason to choose it. For ordinary desktop use or slower games, the low pixel density may be a larger concern than the extra refresh.
