Have had my C9 55" for a week+ now. It's my first 4k and first OLED, so I'm obviously enjoying myself. Figured I'd add a couple of my experiences and answers to questions being asked:
1. I have been struggling with lip-sync to my sonos beam. It's one of those things I'm very sensitive to, and I can't quite convince myself I've solved it. Still seems like the audio is slightly behind the picture most of the time. I'm using HDMI ARC, have tried all the settings but settled on DD output with 'pass-through'. Have tried toggling back and forth between av-sync off and on with 'bypass' selected, but can't seem to decide which is better. Any tips I'm missing here?
2. Someone mentioned needing to lower brightness to get true blacks. I noticed this last night while watching netflix (via tv app). Somewhere between 47-48 seemed best to me in a dark room, but I will want to keep playing with it. I haven't done a proper calibration yet (and don't have the equipment to do a true isf version). I am still hoping to see more info about what calibrators are recommending for various modes (I know they can't give universal values for color/brightness).
3. The xbox one x seems to work well with hdr/vrr, though the latter is hard to really observe. I'm hoping someone will identify a specific area of a popular game where the framerate normally varies a lot to see the difference. I hooked up my pc today (GTX 1080) and was immediately able to enable HDR mode in windows and select [email protected]
(didn't try 120hz at lower res, but will). Forza Horizon 4 looks great on the xbox, but that only does 30fps @ 4k, whereas my pc can do a solid 60fps, and holy CRAP does that look stunning! I had g-sync enabled on the pc due to my monitor, but I assume it doesn't work with the tv, just not 100% sure how to check.
