New XPS 13 unable to disable adaptive brightness

I am unable to disable the adaptive brightness on the i5 HD 5500 1080p version of the new XPS 13.

When I view a dark page, the screen will dim, and when I view a bright page, the screen will get brighter. This is extremely annoying and all the options I've tried have not fixed this issue at all.


Turning off the enable adaptive brightness option in the advanced power settings does nothing. I have this done on all power plans.

The option for disabling it that should be in the Intel Graphics Driver does not exist.

Disabling the Sensor Monitoring Service doesn't fix it either.

I have the latest version of the Intel Graphics drivers. Uninstalling it doesn't fix it either.

Installing another operating system doesn't fix it either, so I'm assuming this is some sort of hardware problem.

Does anyone have a solution to this annoying issue?

MacBook Pro and Windows 10 in boot camp.
Best solution.

I received my Alienware 13 a few days ago and I'm starting to regret choosing the QHD+ display. The scaling issues are really annoying, but this adaptive brightness is frustrating. This morning I met with a friend who has a MB Pro 2015 with retina (which is 13" also, but 2560x1600) and we played several titles from Netflix at the same time and it was, like I said, frustrating.

Just to be fair, when used outdoors, my panel looked slightly better, though not by the same margin of the indoors tests.

I think that all Dell systems built with this display should receive a fw upgrade to allow us to opt between battery life or image quality.

Having thought I bought a "premium" product, I could write a lot of reasons that everyone else already know, Dell included, of why this doesn't make sense, but long story short, what matters is that we should choose if enabling adaptive brightness is worth or not through our personal experience. As other systems already let their users do. Even our TV's lets us do this.

And yeah, I'm frustrated with this screen. Having seen (and spent a lot of time using) a lot of retina MacBooks so far, I was expecting a lot more from this panel. Unlike the MB retina screens, it never caused the wow effect on me.

Tried to calibrate my display with a Spyder4Pro... Was impossible due to adaptive brightness...

Is this still an issue? Have Dell issued the firmware patch that the post marked as an answer suggests they've been working on?

There is an optional firmware update available for the QHD+ model that allows you to disable the adaptive contrast feature. You will have to contact ProSupport to get it.

For the FHD model, it is not possible to disable it since the display firmware for the FHD panel is not updateable. Dell will not repair it or replace it since the engineering team says that it is functioning as designed and therefore, not a "problem".

Edit: Note that the above applies only to the XPS 13 (9343), i.e. the model with a 5th-gen Broadwell processor.

For the new XPS 13 with 6th-gen Skylake processors, the adaptive contrast feature is disabled by default on the QHD+ model only. The FHD model of the Skylake XPS 13 still has it enabled, and the situation for that model is identical to the Broadwell FHD model.


Edit 2: Whoops, I should've read more carefully. This situation applies to both the XPS 13 (9343) with 5th-gen Broadwell processors and the new XPS 13 (9350) with 6th-gen Skylake processors. 

However, it is disabled on the new XPS 15 (9550) with 6th-gen Skylake processors.

Employees within Dell had requested that it be disabled on the new XPS 13 too, but that model was too far into development/production to be changed.

Disappointing that the FHD version is not fixable, but even more disappointing they chose to not fix this issue in the 2015 version. Clearly it is a problem considering they chose to issue a firmware update in the QHD version and disable this option by default in the 2015 QHD XPS 13. I nearly bought a FHD XPS 13 (had it in my cart and was partially through the checkout process) but decided against it due to the adaptive contrast issue. So happy I didn't given this new information.

Apparently, the Sputnik team requested that the feature be disabled in the Skylake FHD model as well, but it was too late into development/production to be changed. So it's not all that sinister, just unfortunate.

It's not considered a problem in that the feature is working as intended. The only problem is that some people find it undesirable. Personally, I fall into that group as well so I'm equally disappointed in Dell's efforts here (or lack thereof).

Edit: Both versions of the Skylake XPS 13 have the issue. It's the Skylake XPS 15 that doesn't. I edited my post above as well.

I also have a display brightness issue with my Dell XPS 15. It will randomly, while plugged in or unplugged and with a full battery, dim the screen. Most the time it chooses a random brightness to change to. I have my computer set to 30% brightness and it will randomly dim to 5-8%.  I have gone in and turned off all the adaptive brightness settings to no avail. I am hoping with the rumored BIOS this issue will be fixed.

Dell please provide a tool to disable this unwanted feature: the screen brightness adjusts depending on the content displayed: for example when you use a black DOS window, the screen dims so that white becomes grey.

Hey everyone,

I just found this:

http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=513GY

What do you think about that?

They released it yesterday! Does it fix the Adaptive Brightness Control issue?
