Like @sunchaser, my main nav screen is a laptop to in my case a 21" monitor. CE on the monitor, BlueIris on the laptop.
Plus Raymarine AP and MFD (w/CHIRP sounder), next to Garmin MFD (and radar). Will probably replace the Garmin with the new Raymarine HD radar in the next year or two. Legacy radar and sounders above. Not really thought out, it just kind of evolved this way. Guests have a decent view, but maybe I should also move to a 32" monitor.
