    Laptop colors darken when unplugged [not brightness]


    I've recently picked up a Samsung ATIV Book 9 Plus (first windows 8 experience) and have come across a display issue whenever the laptop gets unplugged, namely that the colors become incredibly dark as it the contrast takes a dive.

    Here is a recreation.

    Specs from amazon:


    • Intel Core i5-4200U Processor
    • 4GB (4GB x 1) DDR3 Memory (1600MHz)
    • 128 GB Solid-State Drive SATA3
    • 13.3" LED QHD+, 3200 x 1800, 16:9, 10 Point Capacitive Touch Screen, Intel HD Graphics 4400
    • Windows 8 (64-bit)

      Any help in resolving this issue will be greatly appreciated

    You say it's not brightness, but have you tried using the brightness keys to see if it makes any difference?

    It really has nothing to do with brightness at all. I'm used the brightness keys on my keyboard and adjusted them in the power options while the laptop was unplugged to no avail. This really is just the colors on-screen darkening heavily

    When I unplug my laptop I can see that the contrast starts gradually increasing until all the colors show up like in the picture. I've heard that this might be something related to power-saving but I haven't found anything of the sort in the Intel Graphics Control Panel

    So changing settings here has no affect?

    Huh, my Intel control panel looks nothing like that. I've scoured through it and couldn't find a tick-box for the display power saving technology.

    Mine looks like this:

    Or is this a different control panel?

    Have you tried activating in stead of brightness your LCD background. Most laptops got that with a fn button. My fn combination for LCD background On/Off is fn+f7. f7 shows a small icon with a crossed screen.

    My Laptop does not appear to have the function + F[1-12] for that feature. At this point I have concluded that all I have to do is turn off Intel Display Power Saving Technology but I have no idea how to access this.

    Have you tried going to the Control Panel Power Settings and editing the Balanced Power Plan for Battery?

    There is a setting to dim the display.

    Your machine is factory optimized for long battery life if unplugged, and these are chipset features, controlled thru Windows, reducing consumption through the CPU, rather than just the GPU display features, controlled by the Intel Graphics control. You may also find Advanced Power Options has an option to maximize battery life thru the Graphics system when unplugged, which you can modify. There are features for Dimmed Display Brightness, Display Brightness and Adaptive Brightness as well. At least on my highly unsophisticated HP Compaq Presario, compared to your high-end Samsung ATIV-9 Plus, these features are available.

    It is another instance of having multiple ways to control the system features, hidden behind layers of windows and menus that is making Windows so much less intuitive.

    Your control panel DOES have 'display power saving technology' , 3rd tick down,...and it's toggled ON.
