What is Going On Here

Was out taxi testing my newest RV12, and the engine portion of the Skyview seemed a bit skimpy - and had this vertical line down the middle of that screen. What is going on here? (I think Bob Bogash might have customized it to fit his needs when he ferried it down here)

Check out the Dynon videos and download the installation/config and owners manuals. All of the screens, especially the ems screens, are customizeable.
