Overview
A 260 Hz ceiling gives the 27-inch Asus ROG Strix XG27ACMEG its identity: this is a QHD Fast IPS gaming monitor for high-frame-rate PC play. The 2560 x 1440 panel keeps 109 PPI sharpness while 1 ms GtG, 0.3 ms MPRT and FreeSync Premium, G-Sync compatibility and VESA AdaptiveSync cover GPU brands. Colour is broader than basic sRGB at 90% DCI-P3, and the stand provides 110 mm height adjustment, pivot and wide swivel. Connectivity is useful rather than workstation-grade: HDMI 2.1, DisplayPort 1.4 and USB-C with DP Alt Mode are present, but USB-C supplies only 15W and there is no downstream hub. DisplayHDR 400 adds format support, not strong HDR contrast, because this remains a 1000:1 IPS panel. Buy it if you want fast QHD gaming with stand adjustment; skip it if you need laptop charging, built-in audio or convincing HDR.

HDR & Brightness Reality
DisplayHDR 400 on the Asus ROG Strix XG27ACMEG confirms HDR input support and a 400 cd/m² brightness level, but the hardware has little room for dramatic highlights. The 1000:1 IPS contrast ratio cannot produce deep blacks beside bright objects, and no meaningful local-dimming system is listed. HDR games will run, yet the result should be treated as tone-mapped compatibility rather than a major upgrade over well-set SDR.

Frequently Asked Questions
01 What limits the Asus ROG Strix XG27ACMEG as a laptop dock? +
Its USB-C port carries video and supplies 15W, which is far below the needs of most performance laptops. There is also no listed downstream USB hub, so peripherals need separate connections.
02 How demanding is 260 Hz at 2560 x 1440 on the XG27ACMEG? +
Reaching the panel ceiling needs a strong GPU and reduced settings in demanding games. Esports titles are the most realistic route to frame rates near 260 fps.
03 What should buyers expect from DisplayHDR 400 on this Asus? +
Expect HDR compatibility rather than deep, high-contrast presentation. The 400 cd/m² brightness and 1000:1 IPS contrast leave limited highlight and black-level range.
04 Why are both 1 ms GtG and 0.3 ms MPRT listed for the XG27ACMEG? +
GtG tracks pixel transition speed, while MPRT reflects perceived motion persistence under a different test method. The smaller MPRT figure should not be read as a directly faster GtG result.
05 Is the XG27ACMEG stand suitable for a mixed work-and-gaming desk? +
✓ Yes, it offers 110 mm height adjustment, ±45° swivel and ±90° pivot. That is much more flexible than a basic tilt-only gaming stand.
