Yes. I would like to request a new firmware with the option to adjust brightness and other settings as well, which currently get locked when enabling the sRGB mode.
Target: PG329Q ultra wide color gamut monitor.
Explanation. Currently, the only way to clamp the extremely wide color gamut in monitor to the sRGB color space, which is the one used and required by Windows OS, is to use the sRGB mode. However, that mode disables all picture controls, including brightness. The brightness is above the standard level and too bright for use in a darker environment. No option to change color levels means that it is not possible to calibrate the screen.
When using any other mode than sRGB, the color space is too large and all colors are incorrect - oversaturated.
The only way I currently know about to overcome this issue is to use an app that uses hidden nvidia API in their drivers to do color space conversion. While it seems to work at the moment, it can stop working at any moment, since it is just a single developer on github working on the app, using 3rd party driver api, which can stop working at any moment.
