I recommend setting the input to PC mode for consoles, which reduces lag for all inputs (same amount as game mode) and allows for full calibration and 4:4:4 chroma. For HDR content set the picture mode to HDR Standard when in PC mode, which does get bright and looks good. Setting color temperature to W50 looks fairly close to D65. I find this a very acceptable way to play games.
This is just for the 2017 LG OLEDS. Don't use this if you have a 2016 model or other model TV, obviously.
Out of the box white balance was actually very good on my C7 using the recommended modes (ISF Dark, Warm 2). Made some small adjustments using a meter and HCFR.
Would you mind expanding on this a bit more? What is 4:4:4 chroma? How do you adjust colour temperature?
I'm playing Switch using PC input on game mode which just seems to have the best colour but still looks a touch washed out, but I don't know if that is just the resolution. ISF Dark looks too dark and I can't adjust the warmness either
Thanks for the advice
