Enabling HDR on windows 10

Hi, I need help in setting up HDR on windows 10. My monitor is LG 32UD99-W (DCI-P3 95%) which is HDR compatible and I've been trying to find the best setting that would suit this capability. I tried enabling HDR on windows 10 in settings, namely, turning on the "HDR and WCG", however when I turn this setting on it doesn't look quite right. For instance, when i open chrome it looks very dim and some of the text looks out of place, like it's missing a pixel in each letter. Changing the monitor settings to HDR vivid, cinema, standard, or game doesn't seem to help much with this either. I tried using the slider to make SDR content brighter but that had very little effect on these problems. I tried looking online and one suggestion was to use the NVIDIA control panel setting to this:

Display port connection.

Desktop color depth: 32-bit (only option)

Output Color depth: 8 bpc

Output color format: YCbCr422

Output Dynamic Range: limited (only option)

Upon changing to this setting, it does look slightly better but am not really noticing HDR in videos or games. This monitor was already hardware calibrated. Is the latter or the former method the correct way to turn on HDR?. In regards to google chrome, turning off hardware acceleration does get rid of the dim problem but still the rest doesn't look too compelling. I have also emailed LG support and they said to do it via windows. Is there a correct way to set up HDR?.

(My graphics card is a nvidia 1080)

Kind regards.
