I feed my piano through the PA head and have a couple of powered cabinet monitors in the group to better spread the piano around without having his amp blaring above all. A little extra trouble, but it does give everyone a common reference point. As I understand the Connick setup (a friend has viewed it up close and personal), each of the flatscreens is an actual computer (Macs, from what little he could see). Very expensive and (of course) hard to transport. The flat screen music "displays" (which are probably just dumb Pentium computers) that I have seen (my same friend owns one) are of the type seen at this link: http://books-videos-music.musicians...usic-Display?sku=241190&src=3WWRWXGB&ZYXSEM=0 They are anything but "musician friendly", even if they do a good job with a single page of music. As mentioned above, the size of the sheet is less than 8 1/2 by 11 (which itself is smaller than the standard chart page), the page turning mechanism did not seem to work as well as they would have you think (and the provisions for Da Capo returns to the first page were even more cumbersome), and they are expensive. They do provide a carrying case (for a fee), and I think that there is a multiple display carrying case available. Both these and the Connick computer screens are self illuminating. But, if the computer hangs, you've got real problems.
