U4025QW, aggressive Auto Brightness
Will Dell be releasing an update to not have the auto brightness be very aggressive? I find that in multiple light setting scenarios at my desk, the monitor will adjust brightness too low. I have tried various auto brightness ranges (high, medium, low) and all levels are dimming the monitor too much.

Like you, all we can do is periodically check the online U4025QW Drivers & Downloads page to see if a firmware is offered.
Test the three levels (Low/Medium/High) in Menu --> Brightness/Contrast --> Auto Brightness Range Level.
If still an issue, set Menu --> Brightness/Contrast --> Auto Brightness to Off.

I like the idea of dimming based on ambient lighting as my home office is quite bright during the day, so the brightness setting during the day is blindingly bright at night. However, the Dell auto adjustments are consistently too dim to be useful. Can the interface be modified to allow an offset to be specified?

@DELL-Chris M
Regarding the price of the product, the least I had expected was a decent auto brightness control. The way it is at the moment is not just poorly tuned, it's absolutely useless.
Is it going to be fixed soon?(edited)

I have this exact same problem. I like the idea of auto dimming, but it is WAY too low. I'm getting a brightness of 9% when the ambient light is low (but not dark!), and it looks very bad, strains my eyes. I like this product a lot, but since I paid for it about $2400 (locally in my country), I would expect it'll have a much more versatile auto dimming control. This can still be implemented, so please consider this.

Having the same problem as others mentioned. The auto brightness does work but the setting is constantly way too low to be used. Either fix this or allow us to apply an offset so each one of us can change it according to his needs.

Exactly what others said. Please fix it with an update soon.

Hi everyone,
The firmware update is now available for the U2725QE and U3225QE models. Please check your devices and update accordingly.
If possible, let us know whether the new firmware resolves the auto-brightness issue on these models.
For the U4025QW model, auto brightness sensitivity cannot be adjusted via firmware. As a result, no firmware update will be released for this specific model.
