Windows 11 update KB5053656 lowers monitor brightness

Question

This update seems to have a bug. When I reboot my desktop after the installation, I find the brightness level of my LG monitor has been darkened (not completely black, just darker). It's not a personalization setting issue--the illumination of all images on the computer become darker. I've tried installing and uninstalling the update twice and it's always the same results. Why is this specific update doing this to the brightness of my monitor? If there is no solution, then please tell me how I can block any further installations of this specific update.

Answer 1

Hi, I'm John! I will help you with this.

To narrow things down, have you tried any troubleshooting steps so far, like adjusting your display settings or updating your graphics driver?

It’s possible that KB5053656 is affecting display drivers or power settings. If you haven’t already, I’d recommend checking Device Manager (Win + X > Device Manager), expanding Display Adapters, and updating or rolling back your graphics driver. Also, if your monitor has its own brightness controls, does adjusting them help at all?

If nothing works and you’d like to block the update, you can uninstall it through Settings > Windows Update > Update history > Uninstall updates and use Microsoft’s Show or Hide Updates tool to prevent it from reinstalling.

Let me know what you’ve tried so far, and we’ll figure this out together!

Hello, I noticed the same behaviour in my computer and could restore my monitor to the previous brightness unistalling the last Windows update

Today I just noticed that the update KB5053656 has been downloaded again on my computer and is just waiting for me to restart to install it. Is there a way to block it?

Answer 4

Any idea when we will see a fix for this issue. I did the Update and Shutdown thing last night. Fired up my PC to do some graphics work involving Blender, Photoshop and Illustrator just now, and immediately noticed the problem. It is a major headache for anyone doing any kind of photo editing, digital art or anything similar.

Primary ultrawide LG monitor is almost unusable for any serious graphics work/
Secondary AOC monitor unaffected.

Nvidia drivers fully up-to-date. Issue is not fixable within the monitor's own settings (brightness was already set to 100)

Answer 5

John, Thanks for the quick reply and suggestions. I will look for a different graphics driver but adjusting the monitor's own controls and Windows personalization settings are not feasible solutions. They would misrepresent true colors when editing graphics and videos.I noticed other postings re. the same problem today, so it seems clear that the issue is caused by the update from Microsoft.I did uninstall KB5053656 (which solved the problem), but if I block it from being reinstalled, wouldn't there be a chance that subsequent updates would continue to create the problem?Rick Jahnkow
