Zenbook OLED UX3405 washed out colors on external monitor in night mode

[michal_vlkovic]

Hello,
I´ve recently noticed that the night mode is weird. Compared it on two monitors and definitely the problem is not coming from the monitor itself. I also have Windows 10 desktop computer connected to the same monitor and did a comparison with the W10 as well. W10 night mode looks great but W11 looks like ***

The issue: The monitor is too bright, the colors are washed out and the image rendered is hard to look on.

What I tried:
- played with the HDR, monitor doesn´t support HDR
- played with the drivers for the monitor from the manufacturer and installed default color profiles
- tried all possible Windows settings
- tried all possible settings in Intel Graphics center - not a preinstalled soft on my machine, downloaded it with the latest GPU drivers
- tried other version of Arc graphics drivers

Outcome: No dice. The colors are washed out, shadows are weird, contrast is crazy.

I can change the settings of the monitor but that's not the fix. I suspect somehow the W11 color profile is messy or there's a direct issue with the Arc graphics driver. Been using both monitors for few years (as well on my previous Zenbook UX480) and never had an issue.

Ideas, please? I'm kinda hopeless about this, not-using the night mode is not acceptable and using it with the current rendered image is hurting my eyes.

Thanks for any help

After confirmation, the reported issue is caused by a Windows 11 system problem. 
The relevant department has already reported this to Microsoft. We recommend waiting for the upcoming 24H2 version update from Microsoft before proceeding with the update. Sorry for any inconvenience it may be caused.

Thank you @Falcon_ASUS

@Falcon_ASUSThanks. Does this mean the issue is identified and will be fixed? Is there a link to follow the current progress? Thanks

We have tried the following operations and did not reproduce the previously reported issue:
Using the unreleased 24H2 version, ICM driver, and ASUS external monitor, the night mode issue did not reoccur.

Since the issue has been identified as being related to the Microsoft system itself, we have reported it to Microsoft and hope that future updates will improve it. Thank you.

@Falcon_ASUSOk, thank you. I'll post an update after the 24H2 version update is available.
