There are some sample settings up on the AVSForum, but they may not be applicable to your specific unit. All of them are a little different. I would start with ISF Night Mode, which turns a lot of bad stuff off. Everything else, you pretty much need a guy to come by and set up with test signals and a colorimeter. SMPTE color bars will at least tell you if the PLUGE pulse is correct for black level: HDR is a flag that has to be inserted in the HDMI stream and I'm not convinced a PC can necessarily do it. I have had no problem with an Amazon Fire box or tuning in Netflix on either the Fire or an LG 4K Blu-ray player. And the set itself can be connected to the net and you can use Netflix, Amazon, Hulu, and the other apps actually inside the set. Apple does not yet have a 4K Apple TV box, but I suspect they will in a few months. The Fry's ad on the net says $3200 for the 65", which is in keeping with what we just saw at Costco: Fry's Electronics | LG C7 It's always possible the local store manager went crazy (or made a mistake) and sold it cheaper, but this is what they're advertising on the Fry's website. Even $3000 is a great price for a 65" OLED that's decent.
