Ahh, yes. The greater the rotation, the greater the attenuation of light. Is that how each pixel intensity is controlled?

Here's an interesting question with LCD monitors. If you go into the monitor's control panel and decrease the brightness, what are you actually doing?

Are you lowering the intensity of the backlighting, thereby saving energy?

Or are you just raising the base amount of filtering, thereby using more energy?

Since LED lights are basically either on or off, I wonder if it's the latter?

Re other Distros.

I read about this one Redo and downloaded it

Thanks. This article seems to confirm that.

For best image, I set CONTRAST at 90 to 95% (which usually gives a good black, depending on raster), and then adjust BRIGHTNESS to 50% or less, depending on ambient light. If there is color flare, like in red or orange, I will tweak the CONTRAST down until flare disappears, and then readjust BRIGHTNESS if necessary.

Is this opposite to recommended adjustment procedure? And, does setting CONTRAST so high shorten the life of the monitor?

You guys got me thinking and playing around with my monitor settings. Mine has separate adjustments for backlight level and brightness, so now I'm thoroughly confused. I just use the lowest brightness and backlight setting I can get away with and still be viewable so as not to burn my eyes out. The stock setting kills me. Still don't know the technical difference, but apparently it does adjust something to do with the color producing parts as well as the backlight. So if you have a monitor that has just one setting, who knows which one you're adjusting? Maybe a mix of both?

My computer and monitor are hooked up to a UPS that shows power consumption. I may check it out with full on brightness and backlighting and compare it to full dark and as low as the light will go to see the real difference.

Number time.

Keep in mind these figures are purely for giggles. The extreme ends of the spectrum are unusable, so you're getting info on an amount of backlighting that I'm confident no human eyes could stand for long, as well as brightness that is so washed out it's unusable. It's just for reference.

At my personal setting: BL 22, Bright 43, Con 50
PC and 26" 1920x1080 LED lit: 96 watts total with the PC idling on the desktop with a nice balance of darks, lights, and plenty of contrast needed to show the details.

Cranking the BL up to max: BL 100, Bright 43, Con 50 -- 116 watts total
More Bright: BL 100, Bright 100, Con 50 -- 116 watts total
"No" BL: BL 0, Bright 100, Con 50 -- 80 watts total

As you can see, whatever the Brightness control is adjusting seems to do pretty much nothing to power consumption on my setup, while the backlight seems to be drawing around 36 watts nearly all on its own when set to max. I believe it too. It's CRAZY bright.

I guess the thread is thoroughly derailed now.

Redo Linux that I write about above reminded me of Xpud
in that both are based on Ubuntu and both very small.

But xpud has much more functionality if one download the appications
that he prepared for it.

Sadly he is now unto other challenges so it is not updated anymore.

Any other here that liked xpud?

you can try to install new apps in Redo Linux via apt-get
