Colours seem to be fine for me, but I end up with massively elevated blacks compared to a native non HDR version of the same file. TV is calibrated and the video level is matched as well so it’s not that. I’ve not tried outside of Plex so maybe it just requires an update to the app.
Thank you, plex and NVIDIA! This is working great. Comparison before and after on my non-HDR TV, playing from the updated NVIDIA Shield (it’s just an iPhone photo of the screen, but you get the idea!):
This is still not working for me. Is there a setting somewhere that needs to be enabled? Does this work on all shields (e.g. 2017) or just the 2019 model?
