No Brightness Slider Z390 Designare

[potato_monster]

Hey Folks,

I have an almost perfect Mojave hackintosh build that only has one missing feature so far. I don't have the brightness slider so I had to use my monitor's control buttons to adjust. I see other hackintosh having a slider that don't work, mine does not have the slider at all. I see some solutions (noobplanet) using DSDT patch but I'm a little hesitant to go that route unless it's the only way.  Is this something that can be fixed by kext update? Btw, I'm using a BENQ PD2700U and you can see my specs in my signature. Please help.

 

Thanks!

Thanks for your reply MaLd0n, I have installed the app you linked here and gave it permission in my Security & Privacy settings then I restarted my mac. I still don't see brightness slider in my Display setting. Maybe I'm missing something? I just double clicked the unzipped file and installed it just like any usual app is that correct?

Thanks!

Hi MaLd0n,

It's been a while.  I was a little busy lately. Thanks for your response but it's still not working. F1 or F2 is just giving me the apple signature tone.

your monitor needs to support DDC/CI for this app to work

I checked my monitor settings and it does support DDC/CI and it's ON by default.

if support, idk what happens
