Public bug reported: Setting the monitor to never sleep has no effect, X will force it to sleep after 10 minutes of inactivity regardless of what you set. There is a very simple workaround of disabling that feature in X, but there is no GUI to do this, and it's particularly troublesome for a multimedia PC, where it can be in active use despite no one having touched any input devices for over an hour (e.g. while watching a movie).
Again, there is a simple workaround, but the fact that a workaround exists doesn't make it less of a bug, especially when the workaround requires things that an average user would shy away from (terminal/X settings). I know for a fact that it does this on both Nvidia and AMD proprietary drivers (installed through the additional drivers dialogue), and I haven't specifically tested it, but find it highly likely that it would do this with the open source variants as well. Maybe related to https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/273484 But I didn't find any other reports of monitors sleeping too much.
