I know there are a lot of similar case with me but trust me, i have went through all the possible solutions that I have came across but none of them solve my eye discomfort situation.

So let me share again my problem here and what I have done in order to outcome the problem.

After upgrade to windows 10, my screen brightness can't be changed either using fn+fx or at power option or any other possible places.
Other fn button working fine. Troubleshooting:

1. Refer to ASUS driver and support website - useless due to obsolete driver.

2. Use intel driver update utility to scan and search for latest driver - installed but still useless - version 15.36.24.64.4264 a.k.a 10.18.14.4264

3. Device manager --> update intel display adapter--> let me pick a list from my computer --> 10.18.15.4279 available and picked - useless

4. No brightness slider at power option

5. Adaptive brightness turned off

6. Device manager --> update intel display adapter --> Microsoft basic display adapter <<--- Seriously not practical but i tried anyhow but still useless.

The brightness is killing my eye. Anybody can share their solution especially from G551 or any user with 2 graphic cards.
Thank you.

Yes mate. Installed but not working either. So your fn (brightness) key working fine?

I got G751JT so my answer doesn't matter.

I think I got it all wrong till now:
update your graphics card drivers from the OFFICIAL GPU manufacturer ( I.E Nvidia, intel etc... NOT ASUS! )
I know that MS win10 download and install a driver for the graphics card, but it's never good in comparison with direct install from the GPU manufacturers.

After you do that, REBOOT, problem should be soved.
if problem retains, try to install a beta driver or previous released driver... ( I.E Nvidia, intel etc... NOT ASUS! )

please report back if it solved your problem.
thanks.

Done that with no luck mate.

For your information, I already used the latest version for each and every possible hardware like you mentioned but still did not work out.

ATK Package: 1.0.0040
Smart gesture: 4.05
Intel graphic driver: 10.18.15.4279
Nvidia graphic driver: 358.50

What else can I do to solve this brightness control issue?

okay mine is not upgrade , in my case i did a clean install and about the drivers i did install them all at once with out restarting
the graphic driver i downloaded from nvidia website and i didnt install any graphic driver for my INTEL graphic because it says ur graphic is manufacturer and Lovely asus is not giving us an update for that . after that i moved to this link
https://www.asus.com/Notebooks/G551JW/HelpDesk_Download/

and i choose the windows 10 and i downloaded ATK. LAN hmm thats all

before installing all this i was not able to change the screen brightness and no FN working on keyboard and no light on keyboard

I hope this could help you

Hey mate,

Bummer. Still can't make it work. I don't know what kind of sorcery with this fn button. I don't do from fresh install though which i really want to avoid.
Thanks for the share again.
