Manufacturer specification · Manufacturer port counts and versions; the source device and cable must support the mode you want.
Manufacturer specification · DisplayPort: up to 165 Hz; HDMI: up to 165 Hz; USB-C DisplayPort Alt Mode: up to 165 Hz, at native 3840 × 2160 resolution. Source, cable and selected mode must support the signal.
Match the monitor to the connection. Refresh limits depend on the input, cable and source device. Confirm the exact regional ports, stand adjustment and mount. Manufacturer response-time methods such as MPRT and GtG are different; neither the image nor these figures establish an independent motion or colour-quality test.
9 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. 1 feature is the same under different published names, grouped below. Missing information stays separate.
