Just picked one of these up today off CL for $400. I’ve always wanted one but they’ve become very difficult to find. I do have to say the HDR and Dolby Vision color vibrancy is incredible. I understand it’s a dated TV but I’m coming from a TCL R6 2018 55” so this is night and day for me. Any of you guys have any tips? I’m looking at splitting the cost of a Calman HDR2000 setup with 3 friends and I figure whenever I upgrade it would certainly come in handy. One of them just recently became ISF certified so I feel like he would advise me in terms of the heavy lifting. I see so many people just cut and paste RTings settings and they call it “calibrated” which just seems wildly incorrect.
