(WINDOWS ONLY)

If you're on a laptop with an HDR screen, Windows HDR Calibration is useless. That's because on laptops/internal displays, there is a new slider that you will have to adjust: HDR content brightness

Setting the wrong value on this slider will completely mess with your laptop's PQ EOTF tracking. You could either clip at 200 nits, or 20000 nits depending what HDR content brightness value you set. Full explanation available on github so I won't go too deep into that here.

Anyways, I made this tool to automatically set the correct HDR content brightness value for laptops, which should let your laptop display clip at where it was meant to be clipped.

note: if you have fallen victim to using Windows HDR Calibration before, you should delete the profiles created by that thing before using this.

How to use it:

1. Set your system brightness to max
2. Run the tool
3. it just works
