Instead of replacing the windows with screens, leave the windows and replace almost everything below them. All or a lot those controls on a plane could be put onto visual displays and have the cameras project the ground and surrounding area onto the areas between controls. This would be like a flight simulator on our PC's.
As long as you have some physical controls still available for wing level, altitude, speed, etc up above the windows, it should still be safe if the monitors go down.
I've watched all those Mayday episodes with airline crash analysis and one thing I've learned is that all power on a plane is usually provided by one engine. Lose that engine and your power goes out. They need to fix that and add a lot more redundancy before I'd ever trust them to replace a window.
Besides, anyone who has watched the end of ST2 TWOK can tell you why a big view screen is no match for a nice window. No nebula would have messed up a window's view!
