Overview
At its core, the ASUS ROG Strix XG248QSG Ace uses a TN panel offering 1920 x 1080 pixels / Full HD / 1080p and a 48 Hz - 610 Hz / Overclock - 610 Hz / DisplayPort - 27 kHz - 851 kHz; 60 Hz - 610 Hz / HDMI - 27 kHz - 851 kHz; 48 Hz - 500 Hz refresh range. On motion, the panel is rated 0.7 ms GtG and 0.1 ms (MPRT) MPRT; GtG and MPRT use different test methods, so treat them separately. For picture quality, expect 350 cd/m² typical brightness, 1000 : 1 contrast and 99 % sRGB coverage. On the sync side, FreeSync, G-Sync is supported. On connectivity, you get 2x HDMI 2.1, 1x DisplayPort 1.4.

HDR & Brightness Reality
The HDR10 / DisplayHDR 400 specification is more credible than a 400 cd/m² panel with no peak reserve, because the sheet lists 350 cd/m² typical and 500 cd/m² peak brightness. However, this remains a TN (AU Optronics) display with a 1000 : 1 contrast claim and no published local-dimming system. HDR content is supported, but the hardware figures do not suggest the black control of a self-emissive panel.
