Issue after update (screen brightness, external display, etc)

Greetings.

I've been having a display issue with my ASUS laptop for a while now, but I haven't been able to find any answers and I finally ended up here.

So I've been using this laptop for about half a year now. Just a small background, it's a windows 10 laptop with Intel HD 520 and nvidia geforce gtx 950m. If anyone needs more details, please say so.

Anyhow, everything was fine until a microsoft update at the end of August, when suddenly I couldn't adjust the screen brightness of my laptop anymore. It was fixed to maximum, and even setting it to powersaving did not change its brightness. I've tried just about everything I can find (update drive, uninstall & reinstall drive, edit directory, etc), but to no avail. But it wasn't painful to use, and I stuck with it.

But then I recently discovered that my laptop also can't detect external displays anymore, as in HDMI and so on. Before that update I had used it several times, no problem at all. But now it won't work. I've tried it on multiple TVs, with several different cables, and nothing. And to top it off those TVs are working fine, as other computers and gaming devices work perfectly.

Again, I've tried what I could find, including installing older drives, but still nothing.

Please, can anyone help me with this?

Hello Y_H_M:

 

 

Thank you very much for providing all those details.

 

 

Since the laptop works with Intel® HD graphics 520 controller, the best thing that we can recommend from our end will be to delete the current graphics driver manually, and re-install driver 4501 manually as well:

 

 

Un-install driver manually:

Install the driver manually:

Driver 4501:

If the driver above does not work, you can try also the beta driver 4539:

If the problem remains then you can always use the graphics driver provided by ASUS for this specific laptop:

 

 

https://www.asus.com/us/support/ https://www.asus.com/us/support/

 

 

Since the laptop is also using Nvidia graphics, the problem with the external monitors not being recognized could be related to that graphics card, to look for Nvidia drivers use the following link:

 

 

http://www.nvidia.com/Download/index.aspx?lang=en-us http://www.nvidia.com/Download/index.aspx?lang=en-us

 

 

Besides that you can also try a BIOS update the latest version on the laptop.

 

 

If after trying the steps above the problem remains, then the best thing to do will be to get in contact with ASUS directly, in order to get further tehcnical and warranty assistance:

 

 

ASUS's support site: https://www.asus.com/us/support/ https://www.asus.com/us/support/

 

 

ASUS's phone number: 1-877-339-2787

 

 

Any questions, please let me know.

 

 

Alberto
