The only reason why i even bothered with updating my driver was b/c last year, i had bought a new monitor and connected it to my asus laptop. It would randomly go to sleep the monitor. It was an HP. My initial thought was the monitor had an issue and i read lot of hp monitors had this issue. However, i then used my asus laptop with my dell monitor... and it was the same thing. The thing is my dell monitor when connected to my dell xps 8100 never had this issue whatsoever.
I also used another monitor and oh behold same thing. So thats when i figured out its not the monitor issue, its the laptop issue which is why monitor would go black randomly when connected to my asus laptop. Some times it would go to sleep once every few minutes, other times it would every few hours. Usually on average i say if laptop asus on all day, it does it 3 times at least.
So when i had this issue, i went and updated my driver but after installation, i could never restart the computer. Had to system restore each time b/c the repair never fixed it. So b/c of this, i never bothered to update driver again b/c each time i did that, computer never loads and always turn black each time.
Someone had thought the reason my monitor go off randomly was power options. I always had NEVER for every option whether on battery or plugged in so thats not the issue.
