    Why don't they have the "dim display after x min" feature in W8.1?

    According to IBM:
    "Dim the display does not display in the edit plan settings. This new behavior is designed for Windows® 8.1. Dimming will be set to occur 15 seconds before display off."

    So is this true? For W8.1, it will automatically dim the screen 15sec before shutting off, but there's no option to set it to dim after a certain idle time?

    Hello Crimson,

    Only for what is in the blue note box at the top of the tutorial in Windows 8.1.

    I don't understand. It just says it won't work if it's not supported by the PC. So it's something built in the hardware? Because the desktop I built is just a normal desktop build. So it's only for something like laptops where the display is integrated into the hardware of the system?

    Correct. Desktops would not have this as an option. Only PCs that have a battery would, but I have not seen this setting available since Windows 8.1.

    Hello usawake, and welcome to Eight Forums.

    This tutorial is for Windows 8.1 as well. Windows 8 is just generic for all Windows 8 builds and versions.

    Be sure to read the blue Note box at the top of the tutorial. If you did not originally have the Dim display after option available, then it means that it is not supported on your PC. etc...

    ran the reg file on my windows 8.1 based tablet and it successfully added "dim display after" to the display power options. however after setting the "dim display after" time, 5 minutes in my case, nothing happens, the screen does not dim. is this feature dependent on setting the "turn off display after" to x minutes? i don't want my screen to ever turn off, i just want it to dim 75% or so after idle for x minutes, my tablet is always plugged in. if i allow the tablet's screen to turn off, the tablet goes into sleep or hibernate mode, depending on the setting, and requires a power button push to waken, i don't want that. any thought or help is much appreciated!

    Unfortunately, if you did not originally have the Dim display after option available, then it means that it is not supported on your PC.

    Instead, your display(s) will automatically dim by the percentage set in "Dimmed display brightness" exactly 15 seconds before what is set in "Turn off display after".

    thanks for the prompt reply but i'm a bit confused, i thought the reg "fix" was for those who didn't have the "dim display after" option originally, i.e. that it would give them it, assuming a battery driven pc... if that's not the case, what is this "fix" for? thanks again...
