Suppose we try to install a screen of the wrong brand (e.g. one that is smaller or equal to the correct size). Suppose further that we somehow beat the mechanical/physical connection aspect of it into submission.
What would it take to make it work on the electronic and software level?
For example, would I need to replace the driver (or some software equivalent for screens)? Is the VGA interface the same in both cases? What other issues could occur?
