No, I learned how to use the button on my monitor.
Advantages: if you forget to turn your monitor off, you save pow- wait! no you dont! Cuz some other crap just comes on the screen!
- Your monitor wont have any pictures "burned" into it by leaving it on. For some monitors if you leave the same picture on it for too long it will permanently be there (faintly)
Disadvantages:

Kinda Annoying??
If you DO want to save power, go into power options in Control Panel and set your monitor to turn OFF! after a certain amount of time.
