So, bit of a odd one for you.
This new driver causes this issue where If i turn off my main monitor...which is a Smart TV, it will turn of second monitor off....er lose signal. I am unable to get that signal back unless I force reboot my PC. This hasn't been an issue till this driver. So far it only impacts the TV. Both work fine once the reboot is good, its just when I turn it off while the computer is running.
