    Display dim after 20s


    Hi!Since some update ago my display dims after exactly 20 seconds of inactivity. In fact, it does not dim, this seems to be a software effect. The reason why I make this deduction is because all of the background lowers in brightness but the mouse pointer stays the same suggesting that this is not a hardware dimming feature kicking in. What is also fascinating is after an additional 20-40s the display turns completely off. This is not how I have configured my power settings. As a good googler I found a couple of threads addressing this. And I would like to outline what measures I have taken to

    :)

    Screen Display Dim

    Since I updated to the new windows 10 version, my display is quite dim. I go into settings to adjust it and it will not let me. The brightness is at full and the screen is at about 20%.

    Suggestions to fix?

    display dimming

    Hi,

    There's a possibility that this issue is due to the Display settings of your device. For us to isolate your concern, we'd like to ask a few questions:

    • Is it only happening when you connect your device to Windows 10?
    • If it's not connected, have you noticed certain activities wherein the screen dims automatically?
    • Have you tried using a different HDMI cable?
    • What troubleshooting steps have you tried so far?

    We hope to hear from you soon.

    Display dim after 20s

    Screen dimming after 20 seconds

    This just started today, but my laptop screen dims every 20 seconds if I'm not doing anything. Doesn't matter if I'm gaming, watching a video or whatever, if there's no mouse movement or key strokes, the screen dims from it's highest to lowest setting without fail.

    I've tried adjusting the power options, ensured that 'turn off display' and 'sleep' are set to 'never' for all settings, confirmed my drivers on my GPU are up to date, ran all Windows updates, checked the registry and confirmed that the brightness settings are set to %100... I'm at a complete loss as to why this is happening. What's even more strange is that nothing, that I'm aware of, updated today or yesterday, but the issue began as soon as I started my laptop this morning...

    If anyone has any ideas or suggestions on how to stop this, I'd love to hear them.
