It's not a matter of doing xset +dpms, it's generally enabled by default. It's a matter of how it's configured. It has three numbers for different levels of powerdown, usually you'll see three numbers in the GUI configurators too. So "xset dpms 0 0 0" would have fixed your problem too. So the question is what is setting your settings to something crazy and why. I usually set mine to xset dpms 0 0 1200 which turns the monitor off after 20 minutes of inactivity.
