Cannot Adjust Screen Brightness after Windows 8.1 Update

[omgitsb]

Hi, I also had this same problem but my screen was so dim I could hardly see anything. I looked at many forums and tried addressing the problem myself. Nothing I did worked until just a few minutes ago. I already tried updating the display adapter to the new and improved Intel HD Graphics 4000 (but that is the problem)  So I reverted it back to the previous display adapter. I still have all the effects of the 8.1 update but I have my brightness settings back and I can fully return to the right screen display I had before. This worked for me so I hope this will help other people with this problem. 

1) Go into your device manager (select Display Adapters) 

2) Right click the adapter that is listed

3) Click update driver 

4) Instead of Search automatically for updated driver software, click Browse my computer for driver software 

5) Your computer should show the location where the files are located but instead of clicking Browse select Let me pick from a list of device drivers on my computer

6) Then you should see 2 models listed ( The previous adapter that was used before the update and the one you are currently using)

The one that fixed my problem was installing Microsoft Basic Display Adapter rather than Intel HD Graphics 4000

7) So if you are using Intel HD Graphics 4000 as the display adapter select the opposite one to install and within minutes you should have your brightness settings back (hopefully)

I hope this helps someone out.

HP, ARE YOU MONITORING THIS FORUM????? 

HOW ABOUT AN ANSWER, OR AT LEAST AN ACKNOWLEDGEMENT THAT THERE IS A PROBLEM????

What platform product numbers and video card models are showing these issues?

It seems like this has been seen on:

A Pavilion h9 1101 el (no graphics solution listed)

Pavilion i7 (no graphics solution listed)

Intel HD Graphics 4000 (no platform listed)

HP Pavilion TouchSmart 23-F213W (no graphics solution listed)

HP Sleekbook (no specific platform model/number or graphics solution listed)

Compaq Presario CQ-40 315-TU (which was resolved on page 3)

Hi,

Maybe you'll be able to adjust the brightness from the Start screen.

1. From the Start screen, press the Windows + I key to open the Settings charm.
2. In the lower-right corner, click the Brightness icon (it looks like a little sun.)
3. If a brightness slider appears, use your mouse pointer to move the brightness slider up or down to adjust the brightness.

Hope that helps!

P L E A S E read the other forum messages.  After the upgrade, the brightness icon was replaced by "UNAVAILABLE" and when you click on it, it says this option is not available in windows.

i have NO SLIDERS, NO BRIGHTNESS SETTING OPTIONS.

I've tried switching display adapters.  No luck.

Had my windows 8.1 update last week.  Now my computer is so bright I can't look at it.

All methods I know of to adjust the brightness are greyed out.

Help!
