Helios 300 Auto dimming unable to turn off

Unknown

Hey, so I bought myself an Acer Helios 300 gaming laptop to replace my old Acer laptop, and I am very sasisfied with both in nearly every way execpt for the issue they both had in common that no other laptop I've ever used has had, auto-brightness that is seemingly impossible to disable. I've messed around with the Windows 10 power settings and found auto-brightness was already set to off, and in Intel's HD grapics found that the setting wasn't available, so I'm guessing it's not part of the problem. Whenever the screen darkens such as watching a video, the screen will very noticably dim to a pretty low shade, which is pretty annoying on a screen that isn't very bright even at full brightness. It takes me turning the brightness down first, than three clicks back up to full to restore it. My old laptop did the same thing, and I could never figure out how to fix it. The laptop is plugged in and at 100% brightness and charge, and it still does this. I have every single performance setting set to max and just about every battery saving technology turned off and it still does this. Any help is appreciated, as this is a very small but annoying problem for an otherwise phenominal laptop.

So it sounds like you've disabled adaptive brightness in the power options already? Try this, right click on your desktop and click on the 'intel graphics settings' option. From there click on the 'power' option and to the left side of the screen click on 'plugged' in, and under 'select a graphics power plan' set it to maximum performance. I remember having the same problem as you and it took awhile to figure it out. Let me know if that fixes it.
