Helix screen gets dimmer when viewing dark web pages

2013-06-23, 1:11 AM

I had this problem on my X201, nobody ever fixed it other than telling me to turn off the battery profile for power saving. What is the story here Lenovo? I mean this is really annoying. If I view a dark web page, the screen becomes dim SUCH THAT when I return to the white and light web page, it's now dim and washed out, and I have to wait around 20 seconds before it returns to proper contrast.


Trust me, this is not how things should be.

This sounds like it has to do with "Adaptive brightness" settings. It's a windows 8 setting. If you disable this (it's in PC settings I believe) it might fix your problem. White screens/webpages give off more light than darker apps and pages. This light can affect how bright the area is where the ambient light sensor is located. I haven't investigated this specifically on the Helix but I have noticed this in rare cirumstances while delibrately testing ALS on other models. This theory goes along with waitng 20 seconds for it to adjust you mentioned as well.
