Since about October 19, 2023, a lot of times when the Notification Center gets invoked, one or both of my external displays goes super saturated/contrasty. Here's a simulation of how it looks:
It looks almost exactly like two copies of the monitor image are being added together using a "color dodge" algorithm, which basically doubles pixel values and blows out anything over 50% brightness. This makes it impossible to see light gray lines and very difficult to read text, etc.
This can happen both when I open the Notification Center manually (⊞+N), and when a notification pops up (like a Gmail desktop notification). It took me a long time to narrow down what's triggering it. Sometimes it also seems to happen without the notification center being activated.
This happens with two separate monitors of different brands, plugged into two different ports with two different cables, so it's not the monitors or the cables.
It can happen with one monitor or both. Usually when one glitches, the other also glitches within a short period of time.
Changing monitor settings, display resolution, or color profiles never fixes it.
Messing with the graphics cards settings never fixes it.
Sometimes unplugging/replugging the monitor in question resets the color, but sometimes not.
Sometimes, disabling and re-enabling the NVidia graphics card driver fixes it, but sometimes not.
Sometimes, restarting resets the color, but sometimes not.

I've reviewed your issue with the Notification Center causing monitor saturation and contrast problems on your Lenovo Legion 7i running Windows 11 Home. Here are some potential causes and solutions based on the detailed information provided:
Possible Causes:
Graphics Driver Conflict:
The interaction between Windows updates, graphics drivers (Intel UHD Graphics and NVIDIA GeForce RTX 2070), and the Notification Center might be causing the issue.
[]Windows Update KB5031323:
The recent Windows update might have introduced some incompatibilities or bugs affecting display rendering.
[]Hardware Acceleration:
Enabling or disabling hardware acceleration in different applications or system settings can sometimes cause visual anomalies.
Detailed Troubleshooting Steps:
[]Rollback Display Driver:
Try rolling back your NVIDIA graphics driver to a previous version that was stable.
Open Device Manager.
Expand the Display adapters section.
Right-click NVIDIA GeForce RTX 2070 and select Properties.
Go to the Driver tab and click Roll Back Driver if available.
[]Disable Hardware Acceleration:
Disable hardware acceleration in your browser and other applications that use it.
For Chrome: Settings > Advanced > System > Turn off "Use hardware acceleration when available".
For other applications, check their respective settings.
[]Modify Power Settings:
Change power settings to high performance.
Go to Settings > System > Power & sleep > Additional power settings > Select the High performance plan.
[]Check for Buggy Windows Features:
Disable new or experimental Windows features that may have been enabled.
Go to Settings > System > Display > Graphics settings > Turn off settings like "HDR".
[]Manually Reinstall Graphics Drivers:
Uninstall the current graphics drivers and reinstall the latest versions from the manufacturer's website (Intel and NVIDIA).
Use Display Driver Uninstaller (DDU) to completely remove graphics drivers before reinstalling.
[]Check Third-Party Software:
Sometimes third-party software can conflict with graphics rendering.
Check if any new software or updates have been installed recently.
Temporarily disable or uninstall any third-party software related to display or graphics management.
Monitor and Cable Checks:
Although you’ve mentioned the monitors and cables are not the issue, it’s worth testing with a completely different set of monitors and cables.
Also, use different ports if available to see if the issue persists.
Example Reference:
Here is what the issue resembles based on the images analyzed:
The left side of the image shows a normal display setting with proper text and graphical clarity.
The right side shows distorted text, graphical corruption, and oversaturated colors, indicative of a potential graphics driver or hardware issue.
Further Actions:
If none of the above steps resolve the issue, consider:
Reaching out to Lenovo support for any hardware-specific updates or patches.
Reverting to a previous system restore point before the issue started.
Checking for any pending Windows updates that might contain a hotfix.
Let me know how these suggestions work out or if you need further assistance with any specific step!
