Slowly brighteninig/dimming

2013-11-02, 16:57 PM

Can anyone explain why (I have a dark background) when I pull up a white page/box of some kind...my screen will slowly brighten (in ticks).  Then when I close it (back to wallpaper) or go to some kind of dark page...it seems to darken back down in ticks.

 

I've toggled adaptive brightness for my power proifle, windows 8 ambient light option...to no avail.

 

Yoga Pro 2 btw.

I am having this problem as well.

 

I turned adaptive brightness off in the advanced power management settings.  Also set 'Dimmed Display Brightness' to 0% to no avail.

 

I don't believe I had this problem prior to the Bios update.  Any help would be much appreciated!

There's an additional setting besides adaptive brightness to check.

Please see post #2 in this thread: http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Y2P-screen-is-unwantedly-adjusting-brightness/td-p/1330713

1. Turn off Adaptive Brightness in Windows power settings.

 

2. Turn off Display Power Saving Technology in Intel HD Graphics dialogue.
