A 5000:1 contrast ratio and 178° viewing angle keep a split view legible from the side; two HDMI 2.0 inputs take 4K @ 60 Hz, plus VGA, USB and RS-232 control. 2 × 10 W speakers, stand and remote control included.

  • 6.5 ms and 60 Hz: no ghosting on moving objects; ample margin for 25–30 fps cameras

  • RS-232 control: power, input and settings from a control system; remote control included
