Windows 10: With the new windows update my display got dim

Today I installed the new windows update windows 11 version 24H2And when I installed it and restartd my laptop, the screen was dim.The brightness hasn't changed and I have no new apps or new settings on but the screen is way dimmer. The light doesn't change automatically based on the light or apps that I open, it's just significantly darker.There's also nothing wrong with HDR settings or with the power plan settings in neither windows settings or Intel command center.I really have no idea what's wrong with it but it's bothering me big time.I appreciate any solutions or clues suggested.Note:

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

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 try to remediate the issue before making this post so that duplicated suggestions are not given.

- Updated graphics card drivers

- Patched windows

- Installed Windows 11 23H2

- Let Windows update check for all driver patches

- I don't have any adaptive brightness enabled nor even available to configure

- Ran the power troubleshooter without remediation

- Edited my power plan to make sure that display off timers are set correctly. They have been set to turn off display after 5 minutes. This value seems to be ignored

- Ran the Intel Graphics Command Center app and turned off "Display power settings" under System => Power

- Forced enable of "Dim display after" in advanced settings (https://www.makeuseof.com/windows-show-dim-display-after-option/) and then set it to 5 minutes. This value seems to be ignored

- It's not hardware controlled as anything outside of Windows (live USB, BIOS settings, boot menu etc) does not exhibit this behavior

As said this seems to be a software dimming as the mouse pointer remains bright as a shining star. It seems to be a newly introduced feature as my laptop has not behaved like this before.
