HDR & Brightness Reality
DisplayHDR 400 True Black is more relevant on QD-OLED than ordinary DisplayHDR 400 is on an LCD because each pixel can switch itself off. The sheet also claims a 1,000 cd/m² peak and 1,500,000:1 contrast. However, typical brightness and the peak test window are not published, so full-screen and sustained output remain unknown. Expect the specification to favour dark detail and small highlights rather than proving consistently bright HDR scenes.

Frequently Asked Questions
01 What is missing from the XG27AQDNG brightness specification? +
Peak brightness is listed at 1000 cd/m², but typical brightness is absent. The sheet also gives no test-window size or duration for the peak.
02 How demanding is 360 Hz at 2560 x 1440? +
It requires a high-end GPU and games capable of extremely high frame rates. Competitive settings or lighter titles are more likely to approach the panel ceiling.
03 Why does True Black HDR matter on this QD-OLED panel? +
Self-emissive pixels can produce very dark blacks without an LCD backlight. That helps contrast, although it does not answer how bright large HDR scenes can remain.
04 What replaces USB-C in the XG27AQDNG connection layout? +
Video comes through two HDMI 2.1 inputs or DisplayPort 1.4 with DSC. The USB hub uses a Type-B upstream connection and provides two Type-A downstream ports.
05 How flexible is the compact stand despite its shallow depth? +
It provides 110 mm height adjustment, ±45° swivel, ±90° pivot and -5° to +20° tilt. The listed stand depth is 169.4 mm.
