Going to first of all admit, I'm no expert when it comes to color spaces.
I've been using the ACES SDR transform for a while and that's working pretty well throughout my/our pipeline.

But I'm wondering what's the steps to start working with/creating more dynamic HDR content.
I figured starting in Houdini and setting viewport display space to Rec.2100-PQ and View transform to ACES 1.1 HDR would be a good start, but the viewport/IPR render gets completely washed out and de-saturated compared to the SDR view transform. There's not much information about any of this out there, so just wondering if anyone got some pointers?

I did try download the ACES OCIO v2.4 config and use that, but it didn't seem to make any difference either.
Windows and the monitor is running with HDR enabled, and the monitor is set to its HDR PQ_BT.2020 preset.
