Random contrast/brightness fluctuation

[ Edited ]

Sometimes when I alt-tab my contrast randomly changes, which is extremely annoying because I want to see what images look like in one constant brightness setting. There's an icon in the lower right that pops up when this happens. I did some research and found that it might be Lenovo Energy Management's ambient light setting, but I uninstalled that whole program and still have this issue. 

 

Here's a screenshot of the icon in the lower right I mentioned - anyone have an idea of what this is and how to stop it? I was playing a game at the time and the icon was most noticeable there, so ...

Re: Random contrast/brightness fluctuation

Hi Epo,

 

please download  Lenovo Energy Management Software  and Lenovo Onekey Theater first...

http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=611900

 

then go to  Control Panel\All Control Panel Items\Programs and Features  and UNinstall 

Energy Management and Onekey Theater...

reboot your Y560p and then install both programs again.

 

Please post if this fixes your problem! 

BTW... strange... my Y560p has no ambient light sensor settings!
