During its first few seasons the stadium was considered so far ahead of its time that until the 2013–14 offseason, it only underwent minor improvements (aside from seating additions).
The most notable of these improvements came in 2007 when the original scoreboards, video boards and displays from 1996 were replaced with 31.5' x 77' Diamond Vision video boards.
Four ribbon boards were also installed: two spanning the length of the field on either side and two in opposing corners.

In the following years the stadium still wasn't considered as up-to-date as other NFL stadiums.
Several reasons existed, including a lack of surround sound, smaller video boards compared to the rest of the league and poor cellular reception, among others.
During the 2013 offseason, the Panthers renovated the home locker room.
It now contained 74 lockers compared to 66 previously, the interior became more clean and modern, and the team's then-new logo was added throughout.

The Panthers proposed a $250 million stadium renovation project in early 2013, pending a vote by the city of Charlotte to help pay for it.
This plan included two sets of new scoreboards, multiple escalators, infrastructure and concourse improvements, among others.
The subsequent vote by the city failed and efforts to get any money from the State of North Carolina failed as well.
However, in April 2013 the Charlotte city council agreed to an $87.5 million deal for the renovations.
This deal also kept the Panthers in Charlotte until at least 2019.
Despite the lower cost, the renovations would stay true to the team's original plans.
