On YouTube, you get the option of clicking on 360p, 480p, and 720p and sometimes 1080, I believe. I'm assuming you choose one of these settings depending on what your monitor can handle and/or because of what setting the video was recorded in.
In the case of YouTube, I think those options are more to do with what your internet connection can handle, not your monitor. The higher resolution, the better the picture, the more bandwidth is needed to watch them.
