Key strengths

The 3840 × 2160 panel supports a listed 165 Hz native-resolution mode. Check the input-specific conditions alongside the figures.

The listed 200 x 200 VESA pattern gives a mounting option when the mount also meets the monitor’s weight and screw requirements.

The checks that matter.

Before you buy

Response time, HDR support and colour figures are manufacturer claims with different conditions; they do not establish independent motion or image-quality results.

Allow for the 379 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
