Most people use a PSone Screen
. They are cheap compared to other screens, they are a nice size at 5.4", and they accept composite input without modification. If you are getting a PS1 screen, MAKE SURE you get the round-shaped one. Do not get the square ones; they are of horrible quality. If you are getting a PS1 screen, make sure your batteries are at least 7.5v. They can be above that, but you must perform an extra step if they are above 9v. That step will be discussed later.
Many other screens can be used. If you do not decide to get a PS1 screen, make sure the one you do get can accept composite input, and get one that runs under 12v, or picking out batteries will be very difficult. Many pocket TV screens can be used, like the Casio pocket screens
