Is a TV ok? Fred's favorite supplier sells some little tv's that do the job quite well, very inexpensive too. Every input format you might need.
Amazon has some 15" touchscreen monitors that are 16x9. Not sure what their input formats are.
Otherwise, take a look at headrest monitors for cars. Google search raw LCD panels too.
I'm Not an engineer, but I play one on TV. My handle is Tweety but I have nothing to do with the organization of similar name. I just had a really big head as a child so folks called me tweety bird.
