Sorry for slow respond. I'm currently in holiday and I will test it next week.

However, let's move HDR display related issue to https://github.com/iina-plus/iina/issues/8 for easier bug tracking

Works for me

Please don't use screenshot to capture the image because screenshot always works on SDR mode, luminance on the result image above SDR range will be clipped.

I am using Macbook Air 2020 (M1). Its built-in display supports HDR according to the official website. It has a smaller maximum nits than the pro, though. IINA's HDR configuration makes the video overexposed ：（

After using --tone-mapping, the overexposure problem is solved. Probably the same reason as #8.

I'm not very familiar with HDR, sorry for the duplicate issue.
