[Cyrustom]

Well,as u guys know the Dell Inspiron 15 7567 For its terrible TN panel,so did it an upgrade...
Well i swap the Panel with a new IPS 120hz n156hce-ga2,Well it work fine...
But the problem is i cant adjust its brightness...I did reinstall the graphic driver but nothing happened

Is there anyone might have solution for me?

I think this happens with most laptops, you can typically swap to a better / higher quality screen but you loose brightness adjustment, I doubt there is a way to get it back.

Have you checked if your new screens a different connector cable?

 

I also upgraded my laptop screen and I needed another cable because it looked awful with the old one. Works perfectly fine with the new one.

A different cable ? U mean the 30pin connector to connect the new screen?

I am not sure which cable is needed for your screen. I would check the product description of that screen.

If the laptop itself doesn't support high refresh rate panels by default, then yes you can't change the brightness (locked/could not be detected by BIOS)

No other way. You should know the consequence before changing to 120Hz panel

So if i bought another IPS 60hz panel it will work?

Is changing your display brightness more important to you than 120Hz?
