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

We have identified an issue and are currently investigating.
We need to confirm the following with you:

1. What are the current operating system build numbers you are using?
2. Does the problem only occur when the screen projection setting is set to duplicate?
3. If the setting is set to display only on the external screen or in expand mode, does switching to night mode work properly?

Thank you.

Thanks for the reply @Falcon_ASUS Great to hear the issue has been discovered!

2. I´m using an extended mode for desktops, not duplicate. But I assume the issue will be there no matter the mode used.
3. Night mode works but colors are washed out. It looks better during the day with the blue light on.

Let me know if you need more info, thanks for the help 🙂

@Falcon_ASUSAny update, please? I see Intel has released a newer GPU driver. Should I install it or wait for the OEM one? Thanks
