That seems like an unlikely failure scenario. But I imagine if that happened during launch they would pull the abort lever since that would be indicative of a significant failure. Later they and the engineers on the ground would work to control the vehicle either remotely or to fix the displays... or both. And probably abort to the ground as quickly as is reasonably possible.
