Using no background image would save the most resource. Up until very recently I didn't use a bg on my work pc because it couldn't spare any resource use that wasn't crucial.

Any ideas? Or would the difference be negligible?

its stored as a uncompressed BMP, so it doesn't matter if its solid color or anything..
the thing that needs the least energy is tiles

Then what about solid black vs solid white? A completely white screen can produce enough ambient light to partly illuminate a small room but black illuminates nothing. Would energy needed still be the same? Is the black screens energy dissipated in other ways? heat?

I think if it has to load an image, it uses resource, regardless of the image.

oh.., I took your meaning of energy wrong.., I thought you meant resources.., not actual energy.., sorry bout that..

I don't know enough about CRT's to tell you how that works..

Yes so did I. Ya mean that's not what he meant?

no, he means wattage.., like the actual power usage

He is talking about light and heat.., he must be trying to cut down on his energy bill or something

Black. The guns are off when "drawing" black.
White would use the most.

Probably somewhat negligible anyway, though...

Oh, ok in that event yeah, the black would use the least actual ac.

It was just an academic question. I'd been curious about it for a long time and had asked around before but never got an answer.

thanks.

Too much time on my hands!

It would seem that a black screen would not need to energize pixels, but then again: you don't need anything to have nothing, but to project an image of nothing you need something, don't you? Like a painting needs black paint for an image of nothing?

My brain hurts...:confused:

Turn your monitor off and unplug it... the screen is black and it's not even using any power. There's your "black paint" itself-- the darkness of the glass.

(When the monitor is on and displaying other things, the blacks look "blacker" because of the contrast with the other lit portions of the screen. However, it's not really actually blacker than an unpowered monitor screen.)

To quote Nigel Tufnel: "How much more black could this be? None... None more black."

Just gonna give this thread a large bump!
