No one has shared specifics about how the LED screen works with the show yet, but there was an article about the technology: http://www.etnow.com/news/2016/2/pixelflex-hits-all-targets-on-the-if-then-tour-video-design
A fan listed very specific details about tour changes on Tumblr:
*The biggest addition is the projection screen taking the place of the mirrors/trees. They have pics of various spots in the city and maps showing NYC locations. There is some video/movement on the screen at times that is really effective too.
*There are blocking changes. Most noteworthy is when Elizabeth enters at the beginning for "What If" she doesn’t walk directly to center stage and start singing, but instead sits at a table for the first couple of lines. Later, right before "I Hate You" she sits at the table after finding out Josh is leaving.
*"Meeting a man in the subway is like doing your Christmas shopping at Port Authority" has changed to "Seven Eleven" instead of Port Authority.
*A bench warrant is now called a summons.
* Beth sings new lines in Map of NYC after asking Stephen if she can have time to think about it. The part of Map of NYC that begins "22 Reade a building, sidewalk, shade…now a memory that for Beth will never fade…" has all been cut and skips to "Put a sticker on the map.." I asked James about this and if I understood him correctly, the change was made because they cut an ensemble role so didn’t have all of the characters to sing each specific line in the song.
* When Beth is keeping Elena’s baby for her there is a quick reprise sung by Elena of "No More Wasted Time"
* Kate’s lyrics in her verse are changed during "Love While You Can"
*choreography/blocking at the end of Ain’t No Man Manhattan. Josh used to walk off stage to get the glasses he and Liz drink out of but now they are sitting on the table in her apartment.
*When the mayor comes out to talk to Beth about her inviting the NYCC to the ground breaking he says, "Beth, woman you are working my last nerve!" This line was not in the show in NYC.
*When Kate is coming into her "classroom" to talk about American heroes, they’ve added audio that sounds like children playing in the background.
*The delivery/reactions of some lines has changed for Beth/Liz. I don’t remember her laughing at the line "Beth lives alone with cats" before but she is now. Also when she tells Lucas "This is the first time that particular thing has happened" there is now a noticeable pause before she continues with "since I’ve been back".
