Looking for advice on what is going to be the smallest monitor I am going to be able to hook the Raspberry pi up to. It's for my 10 year old to use for scratch which is intro into basic programming, and although it is readily available on PC it's also pre-loaded (i think) or pi. However he is going to build case for it out of Lego and it would be fun if he could enclose a small screen with lego too.
Any ideas, as I'm not too sure the 7inch lcd in car screens will do the trick.
Thanks in advance.
