- Barco's proprietary Sense X automatic calibration system makes sure the video wall is immediately perfectly calibrated. Not only the individual panels, but the entire wall will automatically display the perfect pictures. It is also possible to adjust the video wall to the room's lighting conditions, to perfect ergonomics. When using a competitor's video wall, this operation would require a complete manual recalibration with an external device. With Barco, it's a matter of a push of a button.
