Expected Behavior

From what i see in the spec sheet of the Blackmagic Mini link recorder 4K it supports 1080p60 10bit HDR rec. 2020. So gameplay taken from the switch 2 should present in a correct HDR image

Current Behavior

The preview and output video looks deep fried

Steps to Reproduce

1. Latest Blackmagic Desktop Video 16.1 drivers installed
2. Windows HDR Enabled
3. OBS HDR video settings set
4. Adding Blackmagic Device input
   with HDMI input and Mode "Auto" set

Anything else we should know?

On Linux CachyOS the same behavior is present
Nintendo Switch 2 HDR config is "Always On" and 1000 nits peak, Changing the HDR peak and SDR slider doesn't change the colors.

And I tried uninstalling both OBS and the Blackmagic drivers and installing the desktop video ver. 12.0, same issue persist.

Start with the OBS Studio log at https://obsproject.com/logs/du2iijNHsBxwFSOE and reproduce the issue using the Blackmagic Device input with HDMI input and Mode set to Auto. Compare the HDR preview and output on Windows 11 and CachyOS with the listed driver versions; done means Switch 2 HDR footage no longer appears deep fried.
