What's wrong with my 2013 Honda Civic's i-MID system?

When you mention that the iMID screen of your 2013 Honda Civic isn't functioning, my initial inquiry would be whether you've recently jump-started your car. The iMID has a protective feature that activates "protect mode" after a jump start. Normally, it should resume functioning after a few restarts in this situation. If you're already looking for solutions online, it indicates you've likely tried that. There are three probable scenarios to consider. First, check if the fuse has blown by accessing the under-the-hood fuse box and inspecting the 10a fuse, A29. If the fuse is blown, that could explain part of the issue. Secondly, determine if it's a saved software setting by performing a battery cable reset (details on how to do this can be found in another question). If neither of these solutions works, it's possible that the information display itself is faulty. If it's still under warranty, that's ideal, otherwise, you may need to explore aftermarket options.
