hi sfcaFLYER,
In the bulk head seats the PTVs pop out of the extended center console between the two seats ... I would say they are at about the same level as the other screens ... maybe a tad lower ... and obviously closer to you, which can make for better viewing.
Here is an image of seats 7JK, bulkhead, on the 36J-version on the A340.
