My laptop screen is too bright to look at in the dark even on minimum backlight setting.
On Linux, I usually solve the problem by writing "1" (or the lowest value that does not turn backlight off completely) to a path like "/sys/class/backlight/intel/brightness". This allows precise brightness control because it really controls brightness directly and maximum allowed value is at least 1000 for anything except acpi_backlight.
The question is can I do the same on Windows?
I know I can study open-source Linux driver and roll up my own Windows driver that does the same to control backlight. But I really want to avoid as much of the above 2 steps as possible :)
I also know that some Windows programs can dim screen by darkening the image itself instead of lowering backlight brightness. I don't want such a solution because even black screen is too bright now.
If there is no generic solution, a solution for Intel HD 4600 will do.
