I have a ThinkPad W530 running Windows 8.

When I switch from any darker application to any lighter application the contrast is off and takes a second or two to adjust back.

I can very clearly notice it adjust after alt-tabbing to one or the other.

Any ideas of what could cause this? My first thought is a laptop issue, but it could be something Windows 8 is doing to allow better viewing (after it adjusts it looks really good, the adjusting is just slow)

I had the same problem on my Lenovo X220. I solved it by disabling "Adaptive Contrast Enhancement" in the Intel Graphics Control Panel.

To get there:

  1. Right-click on the desktop > Graphics Properties
  2. Confirm that you are in the Control Panel, not the "Wizard"
  3. Switch to Advanced Mode in the upper-left (instead of Basic)
  4. Click Media > Image Enhancement
  5. Un-check Adaptive Contrast Enhancement
  6. Apply/OK

Its an Intel display driver issue, just go to options and turn it off:

  1. Ensure all drivers are up to date
  2. Right click on Desktop and select "Graphic Properties"
  3. Select Power
  4. Select Power Feature
  5. In Graphics Power Plan Settings, change drop down menu to "On Battery"
  6. Uncheck "Display Power Saving Technology"
  7. Press "OK"

can you backup your thesis about being an intel driver issue? –  Lorenzo Von Matterhorn Mar 21 '13 at 15:10

I noticed some improvement in this. But what made it better somehow is the refresh rate. I noticed that it was set at 40p Hz and changed it to 60p Hz. So it has greatly improved the performance for me.

I am however a Dell Inspiron User with Windows 8.1

The latest UI of the Intel control panel is a bit different and the Adaptive Contrast Enhancement changed to display power saving technology.

Here is what you have to do:

right click on desktop > click on Graphic Properties > click on Power button > then on top left corner where it says Power click on the arrow that shows down > choose on Battery > finally disable the display power saving technology > save

hope this helps as the comments here are outdated

Some laptops have a built in light sensor, this is so it can automatically turn up the brightness in a well lit room.

enter image description here

It is possible that the light from the brighter application is interacting with the light sensor and it takes a second for it to correct itself and set the brightness.

Not the case unfortunately, I do not have one on my laptop. I did find a settings called auto brightness in Windows 8 (theunlockr.com/2012/04/20/…) that I thought would help, but it did not. –  user12834 Feb 8 '13 at 9:00
