Why is my client so messed up?

Depending on your O/S the best bet is to open up the client, get logged in, Alt+O for options, click display tab and check the best supported resolutions from the drop down menu. (I always recommend matching your desktop resolution, windowed: This will make it easier as well to alt+tab back and forth if you need too). If for some reason you cannot match your desktop resolution in game then you can do as BlackBellamy suggests and go into the .ini file.
