Random contrast/brightness fluctuation [ Edited ]

[eponineqq]

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.

Hi Epo,

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

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!
