Questions: What are the most critical picture adjustments for optimum quality? Do you have to go in and optimize settings for every different kind of content source? (HDR-10, DV, 1080p blu-rays, 1080i broadcast from satellite, regular DVD, etc.) I am using only one HDMI input -- from my Marantz receiver -- but watching content from three sources going through the Marantz: an Oppo 203 4K BD player, a Roku Premiere+, and my DirecTV HD receiver/DVR.
For example, the quality I get from the 4K UHD blu-ray of Life of Pi or Dunkirkis amazing; a perfect picture in every way. Regular blu-ray disc also looks very good, as does 4K HDR content from Netflix. Broadcast satellite network programming comes off as a little bit soft and oversaturated, though.
My living room/theater is on the dark side even on a sunny day. Is picture best set to "Technicolor expert" or "Dark room expert"?
Any answers and advice greatly received!
Let's see. The general consensus after reading through the thread is:
That until you break-in your new set by the general use of 200-300 hours of watching your C8, none of the settings you try will be optimal. If you do not have a European model C8 you can find your hours of use in settings General>About This TV>TV Information>Hours. Some people like to run through D-Nice's prep slides to equalize all pixels evenly, but it seems the slides are strictly use at your own risk.
Yes, each source will need adjustments to settings unless you are satisfied with the default LG settings for Technicolor Expert and ISF Dark or Bright Room,which most on the forum seem to think are very close to isf calibration already.
Each source has Picture Mode optional settings specific to it and even the same Picture Mode choice default settings may vary from one source to another. Some settings may be defaulted to being greyed out and not adjustable depending on the source material, such as SDR, HDR or DV. Some suggest starting with the recommended settings proposed for the C8 on the RTings.com website https://www.rtings.com/tv/reviews/lg/c8/settings
The "most critical picture adjustments for optimum picture quality" are Brightness and Contrast. With good calibration reference material (see the AVS Forum Calibration thread) you can set your Brightness to optimum with seeing bar number 18 barely discernibly flashing and number 17 almost imperceptibly flashing. With that then adjust Contrast of agreeable intensity in conjunction with OLED Light at 100 in HDR or 50 in DV and to personal preference in SDR.
You want the Dynamic Tone Mapping set ON when available in HDR Picture Modes, Real Cinema set to ON if available, TruNMotion set OFF, Black Level set to LOW or if using PC Mode to HIGH, Gamma set to 2.2 for day or bright room viewing and set to BT.1886 for night time or dark room viewing, and Sharpness set to 0. If you have the most recent firmware version 04.10.06 and use Technicolor Expert Picture Mode, change the White Balance Color Temp to Warm2 for better color accuracy. All other settings should be at default or OFF.
You want to turn OFF Energy Saving so that the set does not dim the picture automatically to room lighting. Automatic firmware update to OFF unless you do not want to do updates manually.
I may have missed something, so you might want to read through the thread and see.
