Just a few updates as to my TV settings. Still happy with it! I have NOT checked for thomasfxlt's issue as if I haven't seen it yet, I'm not going to (though I'm sorry that happened to you and hope you like your replacement)! I try not to look closer than actual viewing locations. =oP
So after some time with it and being relatively happy with the settings, I still felt like things were just a tad too dim with the Light Sensor On and Brightness (backlight) set to max. The picture was good, but I kept feeling like I wanted a bit more pop. So I'm giving a try at 10 (which is 200 nits according to RTINGS) and I think I'm liking it so far. Definitely a bit brighter than Max with the Light Sensor, but not going crazy with it like my attempts at 18 before, and bright commercials, etc. aren't hurting my eyes.
I'm also giving the Expert 1 Color Temperature again, after going between Warm and Neutral previously. For some reason, I'm liking it more now; I think maybe because the X-Tended Dynamic Range is now off for SDR and was skewing things more than I anticipated. Or it could be the extra backlight level is making it more appealing than when dimmer. I'm not sure.
I'm still painfully debating with myself trying to figure out if I want to use Expert 1 with Game mode as well or stick to neutral. I know games aren't as strictly mastered to 6500K as other content like movies, so I'm still undecided...but I also read that 6500K is supposed to be the standard for everything... We'll see. I've been used to a cooler color temperature for games for quite a long time, but that doesn't mean I shouldn't try to get used to a warmer temperature if it really is more proper for most games.
Glad I didn't wait for the G (75" is the max I can do anyways, so it wasn't even an option). It looks lovely, but even that 85 is $12K. Wowzers!
