Inspiron auto brightness adjust

Hi Nickname643534,

Thanks for posting.  Apologies that your system is not performing as expected.

The automatic brightness control should be located in the Dell Intelligent Display which is sometimes located in the Battery Management window.

Here is some information from the Dell knowledge base you may find helpful:

Dell Inspiron 15 (7570) Usage and Troubleshooting Guide

Disable adaptive brightness to correct dim screen on a Windows 8 or Windows 10 portable device

Hi dell-robert p, thanks for replying.

I have looked in the Dell Extended Battery Life window found under the battery icon on the task bar and there are no options to change.  There are a couple of tick boxes that seem to mess around with the power management options, but nothing I can change.  I have tried booting with safe mode turned off as it was suggested that this displayed further options, but nothing is different.

I have looked in 'power' on the Intel Graphics Control panel and there is very little to change.  Nothing for brightness control.

I have turned off 'Enable adaptive brightness' under display for both plugged in and on battery in the advanced power settings.  Both were already turned off, but toggling them makes no sense.

All settings -> system -> display does not have an option for adaptive brightness.

I think I have covered everything that I've looked at.  If you have any further suggestions I will be happy to try them, but this does not seem to be an isolated thing.  A quick search for adaptive brightness on your forum turns up a few threads all asking the same thing, although the last was a couple of months ago. This for example

Is there a fix, or a fix in the works to allow this to be turned off?

Were you able to try opening the Intel Graphics control panel UI > Power and deactivate Display Power Saving Technology under Battery mode?

Hi dell-robert p,

If this is where you mean, there are no options to make any difference.

@Nickname643534 any tip or trick that @robert p mentions will not work. 

Hi @Aniessh Sethh,

I think I saw some of your responses in other posts but hadn't seen an update on it for a month or so.  I hoped that there might have been some development from DELL since then.

What is even more annoying is that I updated the Intel graphics driver today to solve a different problem (100% GPU spikes causing pauses) and now the CABC works differently.  Before the brightness change was gradual and less noticeable, but after the update it just steps the brightness when it is changed.  Obviously there is some control available so why not let us turn it off?!

Argh!

All technology seems to be getting worse these days, every upgrade or new device provides more problems than improvements.  Or maybe I'm just becoming a grumpy old man!

Were you able to find this setting in the "Settings" tool?  If so, is it not working for you?

Yes, as I said in my second post, both of those options are set to off.  I did make a typo though, changing them makes no difference to what I am observing.

I have noticed the same issue... I have an Inspiron 7570. hope someone will try to solve this awkward problem :(

Thanks everyone for their input.

I am going to try to escalate this Inspiron 13-7373, Dell DBC (Dynamic Brightness Control) complaint.

To do so, send me a private message with the following information =
Inspiron 13-7373 service tag number
Your full name
Your shipping address
Your phone number

Thanks for your patience.

Regards,
Robert

The exact same problem is there for Dell 7570. I have been looking for a solution as it causes eyestrain and distraction during work. Please escalate the issue so that we can have a fix. No doubt Intel DPST and Dell's CABC are very good innovations, but we should be allowed to choose whether we want to use them or not.

same issue, both options off, still the same problem, 

See my post, not sure if it'll work for other Inspiron models, but try at your own risk

I have followed every step described in the guide but sadly it does not work for me (Inspiro 7570)
