Prevent display from turning off due to inactivity when watching full screen video (windows 7)

In power options the monitor is configured to turn off (go to power saving mode) after 10 minutes of inactivity. The problem is it also turns itself off when I watch long YouTube videos in full screen.

I like power saving, so the default behavior is OK, but it shouldn't kick in when I watch fullscreen videos.

Is there a way to fix it?

Solution 1:

But there is a workaround:

Make sure you use the Zen Jiggle mode to avoid any onscreen interference with your viewing pleasure.

Solution 2:

Actually the software CAN ask windows to turn power saving off. Thats how media players do it. But when you watch youtube or other flash videos it is the browser that's running, nothing else. There is a flash plugin but this is a plugin, it only has access to the same things the browser has. If the browser does not provide access to power saving management the plugin can't access it. So the only way for that to be solved would be that browsers could have a new feature that would disable power saving when you visit some certain sites or has the ability to manage power saving and somehow passes that access to third party plugins. I don't see there is another way. or, you could go to the start menu and click on power options (search it) and then once your in you can click on a thing that let's you change how long until the computer goes into sleep mode.
