Shades Feature Request

Brightness on an iMac

  • Status: Not Possible

Description

On its laptops Apple lets us dim the internal display all the way down so that the backlight is turned off when at the lowest brightness level. However this is not possible on desktop computers like iMac. The backlighting is at its lowest at the lowest point of the scale but never reaches the state "off".

Can you implement such a feature in your product?

Hmm... Shades doesn't currently affect the backlight at all, it merely obscures the display. I'll look into this, but I can't promise anything.

So how do you affect brightness, if not by changing the intesity of the backlight?

Shades draws a translucent black rectangle over the entire display, and varies the opacity to achieve different brightness settings.

It doesn't save power, but it has the effect of reducing brightness, and helps avoid pixel burn on CRTs.

Hi!
It would be nice to have an individual "overlay" to compensate illuminating errors. For example, my Imac 24 ist darker on the right side than on the left. An individual overlay which is darker on the left side would compensate this...

I thinks it's a VERY useful addition to the color calibration of the screen. Calibration loses much of its value when the screen back lighting is not uniform

I'd really appreciate this option: 0% brightness turns the backlight off! Since I use my iMac for watching movies on my TV set, it would be great to turn off the iMac's internal screen.

BTW: the dual display option works like a charm, but only when not in mirroring mode. In mirroring mode one can only set the external display's settings.

Great tool, thanks a lot!

I would really like this feature. When I go to sleep, I see light coming from the screen, which is annoying :)

after searching the web for hours I´m sure, there is no way to turn the internal display completely off, and there are many users who need this feature for their home cinema. If you could handle to add this feature lots of respect from t he whole imac - home theater community would be yours, and probably some tips for your work, too. Thanks for your nice program so long,

there is an pmset command which turns the monitor completely off. but its not very handy handy to turn it on again via console ...

so, there's definitly a way to do it ...
