additional improvements included a/v and architectural upgrades to the stadium. in response to the west end-zone project occupying the space where the scoreboard had been, a new video display was installed on the stadium's east end. it measures and features the latest light emitting diode (led) video technology. the video board is 112% larger than the previous board while producing a wider, more consistent viewing angle. the video display is more than double the size of the previous display with four times the resolution. it is one of the few hd video displays in college football as its 1708 x 840 resolution exceeds the hd standard. the project also included the installation of an led ribbon board that measures four feet (1.3 m) tall by wide and runs along the length of the premium seating side. a ribbon board was then added above the north stands in 2014. both the video and ribbon boards display game statistics and information, out of town scores, along with graphics, animations, crowd prompts, and opportunities for partner-related elements. a new custom audio system, which is integrated with the video and scoring system, was also installed and engineered to provide full-range sound reproduction and deliver clear and intelligible speech at martin stadium.
