Surface Pro brightness bug

Anonymous

The surface pro randomly brightens and dims even when auto brightness and dimming is completely shut off. I contactedMicrosoft chat support and they said they are aware of the issue but its taking longer than expected. I just wanted to post here to create more visibility and awareness of this annoying bug. I hope it gets fixed soon. Its most noticeable when an app launches or while beginning to watch a video. From what I've heard it happens with RT too.

Great news folks! I was able to fix this issue!!!!! :-D

So the issue appears to be the Intel HD 4000 implementing 2 forms of battery saving contrast adapting. But we have no ability to change these settings by default.

So first of all make sure your dynamic brightness is turned off in your PC Settings and/or battery plan. Then...

Go Intel's site and download and then install the latest driver for the Intel HD Graphics 4000.

I believe this is the correct link -

EDIT: Oops my link was for the 32 bit driver. This is the one you need -

http://downloadcenter.intel.com/Detail\_Desc.aspx?agr=Y&DwnldID=22375&lang=eng&wapkw=intel%C2%AE+hd+graphics+driver+for+windows+7\*+and+windows+8\*+%28exe%29

This should give you access to the Intel Graphics and Media Control panel when you right click and select Graphics Properties from the desktop.

Select ADVANCED MODE

GOTO > MEDIA > IMAGE ENHANCEMENT and disable "Adaptive Contrast Enhancement"

Then GOTO > POWER > Change POWER SOURCE to "On Battery" and make sure "Display Power Saving Technology" is disabled (that is unchecked).

Click APPLY and viola no more dynamic contrast annoyances!

YAY!

Greetings Gary,

Thank you for letting us know. Can you by chance get a video of it happening as this is something we are looking into.

The screen will dim and brighten at random times. This happens regardless of the state of the automatic screen brightness switch setting.

I very rarely encounter this, a couple of times I thought I had it was just the video rapidly switching between two scenes one having about 25% of the screen near white the other being mostly black background.

As for the real problem for me it's not very noticeable when at the dimmest setting. But as for the flash it only occurs maybe twice a week but not necessarily on batteries, I seldom use it on batteries which is maybe why its so rare for me at all, but I know I've seen it plugged in and usually in a dark room.

Greetings Prose16343,

We were hoping you could create another video of the brightness issue. Would it be possible to do this outside of the Xbox Video app, in something like Internet Explorer, or another app?

Unfortunately i didn't make the original video someone else did, my iphone can't seem to capture the screen well enough with enough light to show the problem.

This happens the most when an app just launches. And it happens with video. It might take a while to present itself, just keep using your surface on battery and surely you'll see it. Its subtle but definately there.

It's hitting the news sites now, lots of people seem to have it, im guessing not everyone knows that they have it
