When did this happen? I remember having it enabled along with 90hz before ,why is this restricted now to only 60hz?
This is restricted by design due to user feedbacks.here i will share few replies from moderators for ROG 5 user queries regarding DC dimming.👇👇
Another reply from same mod is this👇👇
if you turn on Auto, the DC dimming will be disabled under 60Hz low light source. This function is an expected design and is not castration after revision; because when Auto is turned on, depending on the user's use situation, more frequent FPS switching may be encountered. If DC/PWM dimming switching is added, it may bring poorer vision to users Fatigue and experience.
I hope this will help you understand the real reason behind.
Alright, thanks for the explanation!
I never really noticed any change when switching this on while 90hz was on, so I suppose it wasn't working anyway then. But it would be nice to include such changes in the changelog when something like this happens next time :)
