Preventing display sleep

Message #1 - Posted 2008/03/15 - Barry Margolin

OS X allows you to configure "Disable Screen Saver" hot corners. But what about display sleep? It doesn't look like these corners disable display sleep. I have my display sleep time set shorter than my screen saver time, because I don't like screen savers (if I'm not using the computer, why do I need anything displaying on it? Flying toasters were cute 20 years ago, but I'm over it).

I've even installed the Basic Black screen saver, but it doesn't turn off the backlight, so the black screen still glows.

So does anyone know of anything like hot corners but for disabling display sleep?

Try Jiggler. Worked fine for me using both Panther and Tiger.

Disabling display sleep with or without a screen saver would be an extraordinarily bad idea IMO.

Why? Other than saving electricity, that is. LCD monitors don't suffer burn in like CRTs do.

Well unfortunately, backlights don't last forever, and LCD panels can go out as well - both of which would stay powered on. Have you ever had to replace either one and pay for it? It's quite expensive.

BTW, LCD displays don't suffer burn in *like CRTs*, but they are indeed susceptible to a different kind of burn in:

Nope. But regardless, if for nothing else than power wastage, I do have both screen saver and monitor sleep turned on. Dunno why I bother with screen saver, though, other than that I like flying toasters.

Yes, I find Jiggler useful too.

It has just occurred to me that there are times when I would like the display to sleep but not the computer, and Jiggler will stop both kinds.

Yes, of course I know that I can set different computer sleep and display sleep times in Energy Saver. What I am thinking of is situations (I can give details if people think they are needed) when I want *temporarily* to override the computer sleep time without going to the bother of resetting Energy Saver and then setting it back.

Scripts (shell script or AppleScript) that could do the override and setting back to normal settings would be fine. So might a different application.

I don't want to disable it permanently, just while I'm doing certain view-only activities where I don't touch the mouse or keyboard often.

Jiggler is the perfect solution.

I never use the computer's automatic sleep. If I want the computer to sleep, I use the Sleep command in the apple menu.

Actually, I almost never put the computer to sleep at all. I've only done this with laptops, usually by closing the lid.

That is different from burn in, which cannot be reversed.

I did state that it is different. It's still a form of burn in.

It says turning down the brightness will preserve backlight life. I wonder if that's true of other monitors. I'd read that backlights always ran at full brightness.

But it's still pretty annoying. I have an LCD display at work which has faint echoes of someone else's Windows desktop on it, and since I am just a contractor it's not likely to be fixed or replaced. --

That way suits you. But it doesn't suit me. If I am recording a radio program by a schedule when I am out then I want the computer to sleep after completing the recording rather than being fully on for the hours until I return.

Come to think of it, I can do that as Audio Hijack would let me run a script after it has stopped recording But that could be inconvenient at times also.

Anyway, neither your post or my thought in the previous paragraph rsponds to my original question.

Which is probably a question I should have asked, though my machine is an iMac.But also, what are the specific advantages of keeping the machine awake.
