maybe the exact computer reference could help
To modify the display parameters, there are several solutions depending on the system and the graphics card.
certain parameters can be modified under windows 10 under certain conditions

https://support.microsoft.com/en-us/help/4027563/windows-10-set-your-display-for-night-time

most options need to be changed from the graphics card control panel
for nvidia for example:

I am sorry to say this, but in my experience, ... is the one of the worst product. I can not adjust the brightness and contrast means what the hell this product. I gone through the ease of access and adjusted the brightness at the level to 0 but still its looks like 100 watts bulb. There is no option to reduce brightness and contrast at my requirements. very sad.

Desktop Model number is HP All-in-One 22-c0xx.

The keyboard came along with this system does not have any Fn key for adjustment of brightness. I already adjusted the brightness level to 0. I tried in Night shift ON mode also but still it is too bright. I need to know whether this useless product has any feature to adjust the brightness further.

It seems to be this model:

so Nvidia card ..
apart from the options available from the Nvidia panel there are probably not too many options
I don't know if the settings are closer to laptops, for this type of machine.
