what are you from the 50's
glas cockpit is just like watching TV
no you have the basic displays thats called a PFD in a boeing and MFD in a Airbus dont ask why its just the way it is ::) on the Top PFD which is primary flight display, you have you basic T, with altimeter and all that stuff
the one below or next to it depends on what plane you are flying, is a ND navigation display, and you can make you PFD show on your ND and vice versa at least in the real life it can.. I dont know about FSX since Im just installing it now.. But Im sure that it says something about glas cockpit in the learning center.. if not give me a PM and I'll give you some hints

best
