As mentioned above, some displays store separate settings for different formats. For example, my Vizio M70-D3 stores settings for SDR, HDR10 and Dolby Vision and automatically loads the proper saved settings as the format changes. There are quite a few LG OLED owners here, so I am sure someone can provide insight on how its settings work.I have a 65 inch LG OLED - I saw a comparison on YOUTUBE for Warcraft and the film was very dark and didn't match the blu ray until the settings were changed according to what was appropriate for 4K. Having to play around with the settings if I switch back and forth between regular viewing/blu rays and 4K seems very bothersome.
If your LG display is like my Vizio, each mode will need a unique calibration. In the case of my Vizio, I had to actually feed the display each of three modes (SDR, HDR10 and Dolby Vision) in order to calibrate for each. I doubt any displays out there are optimal using the same settings for different modes.So I just get the TV calibrated in one mode for everything (Geek Guys usually calibrate one picture mode like Expert daylight) or do I have to get an additional mode calibrated like HDR mode for the 4K material ?
