Refresh rateUp to 500 Hz

Samsung notes the maximum may vary by input source; reaching 500 Hz requires a source that can output it.

Variable refresh works over HDMI 2.1; dynamic refresh rate (DRR) over DisplayPort is also listed for Windows.

Dell
Response time0.03 ms (GtG)

GtG is the time a pixel takes to change from one grey level to another; lower values mean less smearing in motion.

Samsung		5 ms GtG (fast mode); 8 ms GtG

Pixel transition specification, not total input lag.

Dell
Brightness300 nits (typical)

The typical figure is for full-screen SDR; small bright areas go higher in HDR.
