Hi. I recently purchased a cheap LCD that attaches to my Pi via its GPIO pins. It's an incredibly small LCD, but it works well. The only issue is that it's through GPIO, so there was a lot of driver issues to go through to enable it to display the console and x11 interfaces. Unfortunately, I haven't managed to enable other key programs to display to its framebuffer, so it's pretty much useless to me now.
Anyway, I'm here because I'm looking into getting a composite or HDMI LCD to attach to my Pi, seeing as how GPIO has issues, and the fact that there isn't an official LCD for the Pi as of late. In your experiences, is there a great enough difference between composite and HDMI that it'd be worth spending the extra cash on an HDMI LCD for my Pi? Do you know where I could find a 3.5" or smaller LCD in the form of composite or HDMI for my Pi?
