Key strengths
The 5120 × 1440 panel reaches 240 Hz on every input with a 0.03 ms GtG response rating and 99% DCI-P3 (CIE 1976), and PIP/PBP plus KVM let two computers share the screen and peripherals.
Before you buy
With the stand it is 1195 mm wide and 328 mm deep, so it needs a large desk.
The stand has no portrait pivot and the hub is USB 2.0. The 1000 cd/m² HDR figure applies only in Peak 1000 mode at 3% APL; typical SDR brightness is 250 cd/m².
Every specification. With its source.
