    Can't adjust brightness or connect to a monitor..


    Hey guys, just updated to windows ten with my Sony Vaio 14 touchscreen laptop. 2 things ive noticed so far that have been bugging me is 1. I cannot adjust my brightness with the f5 & f6 keys like i could before... nor do i know how to changed the brightness now at all. Also is anyone else not able to connect to an external display (i.e. monitor or TV) used to do it automatically with 8 now nothing.

    Thanks!

    There might be a function key driver that you need to download from Sony and install.

    For recognizing a second TV/monitor you might have to download and force install the manufacturer's driver for the video GPU.
