Hi. I am also new owner of this set (65xd9305) and also have issues with clouding. Did you only set localdimming on medium or also turned off xtended dynamic range completely? I am still searching for settings to minimize it. For the player, I'd like to know it too. I can do this on my htpc (using PotPlayer) but can't do this for HDR enabled MKVs. Also to note that i.e. Hunger games with HDR looks pretty washed out and I am much better of with the non-hdr version, no matter what I choose for the picture settings. This display simply seems to much bright and with HDR content is not able to produce deep blacks. I would love to be wrong on this one (!)I would note that I had some horrible clouding issues when using high settings on local dimming and XDR and that issue was solved very clean by going with medium setting on local dimming.
Question: does anyone know a good software that allows you to change the color of subtitles when watching movies? Plex is a no go, Kodi and SPCM has some issues and for now I have to watch movies without subtitles to enjoy a crisp black contrast!
