I have a new Dell Inspiron 15 7000 laptop with an i7-4510U, Intel 4400 Graphics, 1920x1080 screen, and Windows 8.1. I have noticed that the display will brighten and dim when switching between apps. For example, going from a dark desktop background to a white background such as File Explorer, it will take the display about 5 to 10 seconds to brighten to the appropriate level. Going back to the desktop it will dim and sometimes even show a quick flash. I have the display set at 60% brightness and have turned off the adaptive brightens. Also using the latest Intel drivers. Exhibits this behavior on battery or AC. Never seen this on a laptop before.

If this is a new computer and still under the warranty speak to Dell support, your graphics card may be defective.

Hi voyager72,
I have recently purchased the same model Dell and am having exactly the same issue as you have described. I am wondering if you managed to find a solution to the issue with your machine?

I found that the Intel graphics driver 10.18.10.3621 needs to be used (dated 5/16/2014). Right click the Desktop and click Graphics Properties and click the Power settings. Use Balanced for Plugged In and On Battery, disable all three settings. I found that if a later Intel driver is used, these settings are not available. This solved my problem with this screen.
