The standard Boeing 777 layout is six CRT/LCD type screens. The two centre screens are used for Engine parameters and warnings and the bottom one of these two is normally used on the ground by the engineers [in fact in flight many flight crews fly with the lower centre screen off]
The two screens of each of the Captain and First officer's side are mirror images with the outer normally being the PFD [Primary flight Display] and the inner being the ND [Navigational Display] I say normally, as the thing about modern airliners like the Boeing 777 is that the screens can be switched to any of the displays either manually or in the event of a failure, screen switching takes place. The ND [Navigational display] gives you a "moving map" type display
With regards to steel cables you can still find some below the floor in underneath the flight deck from underneath the control column as Boeing didn't go to a completely FBW system until the 787..
