In terms of the corner view of the videoboards, we recommend being in a higher row (greater than 10) so that you have a better view of the big board on the sideline. In that case, you'll have no problems with being distracted by both boards. Otherwise, you'll have to look straight up to see the replays and your angle won't be very good.

Better views of the videboard will be found in the higher rows of Section 118, with a decent angle to the larger sideline facing screen (image above taken from Section 118 Row 20)
