Hi there - what does it mean it will be cut off to blank? The entire screen will be black? |

By blank I mean pure white, part of the image/video ( those brightest pixels will), for instance youtube<https://www.youtube.com/watch?v=z4swrq4ucfQ&t=556s> on 0:17, the show ground will show full blank white on my external display (600 nit, full brightness, full contrast). More detail on my internal Display(1600 nit)
I can adjust the external display with (600 nit, full brightness, 50% contrast), then I can see the details, but anything else is gray, and not good.
The issue is out from a fresh fish: is there any way to suppress this margin cases? i.e. if I can set up certain mapping function such that brightness over 550nits can be mapped into 550-600 nits.

Oh, you mean HDR clipping. Yes, this is a side-effect of gamma table manipulation (this works only on the SDR range and any brightness levels beyond this will be collapsed back to max SDR brightness). I advise you to switch to BetterDisplay:

I took a trial on Better Display, I’m not sure I have understanding the content on the wiki you suggested, but I’m afraid I haven’t make that works.
Moreover, I noticed this discussion: waydabber/BetterDisplay#2075, it seems that the HDR clipping is inevitable, I understand I should ask relating questions in BetterDisplay’s repo, but can you help me confirm if this discussion marked my issue is inevitable?
Regards

Hi I've got an HDR Monitor, and I have got it working pretty good for SDR and HDR content with this app. However, when it comes to extremely bright content, i.e. over 400 nits, it will be cut off to blank. Any idea how I can set things up to make them mapping to an reasonable range?
