Key strengths
The 2560 × 1440 panel supports a listed 240 Hz native-resolution mode. Check the input-specific conditions alongside the figures.
The supplied stand has a listed 130 mm height adjustment, allowing its position to change without adding a separate mount.
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 207.7 mm listed depth with the supplied stand, plus cable clearance. Check desk depth before choosing this size.
