Displays cant get second monitor to work in windows

got a old monitor that I wanted to use to throw teamspeak onto, or youtube videos whilst doing other stuff

however, it will not work on windows, when booting up the bios displays on it correctly, and it works fine in ubuntu , however, windows keeps giving me this on/off response (crappy video I know, but demonstrates waht it does constantly) (ignore screen resizing, just needed it to load something to the other screen)

laptop is a clevo w230ss, so its intel graphics and nvidia gtx 860m on windows 8.1

 

Have you confirmed that the monitor works with another PC?

 

monitor works fine on desktop, works with this laptop in linux and bios, so windows/nvidia driver thing

 

Trying setting Windows to "Extend desktop" to second monitor and see what happens.

Windows knows how to work with multiple monitors with no problems so for sure, this is either a graphics driver problem, or graphics hardware problem.

 

done that, no luck there either

fairly certain its nvidia drivers, as it works fine on ubuntu so the hardware works fine
