SDR is everyday desktop content. More brightness can help in a lit room; reflections and the size of the bright area still matter.

HDR measures bright highlights in games and video. A small-window peak is different from full-screen brightness, so check the window and mode.

Delta E measures the difference from the target color or gray. A calibrated result describes that setup; it does not establish factory accuracy.

Motion & delay

Lower time = faster
Black-to-white response
0.24 msOne-inch square

Pixel response affects moving edges. Input lag is delay before the image starts changing; screen draw and signal processing are separate tests. Compare like-for-like methods.

Response, signal processing and total lag are different metrics; do not compare across lab methods.

RTINGS’ exact 27GX704A-B verdict confirms downscaled 4K at 120Hz from PS5 and Xbox Series X|S through HDMI 2.1. It also reports connection issues when switching from PC to console; these are test observations, not a population failure rate.
