I haven't had a chance to go through all the posts in this thread, so I'll come back and edit this when I do, but I just wanted to post my experiences since owning a P55-F1 since January, and see if anyone has some tips:
So I'm coming from a 720p LG plasma. I got the P55-F1, which I'm ~90% happy with, there's just a couple nagging details that I haven't figured out how to remedy.
Input-wise, I have an Onyo TX-NR626 plugged into HDMI1 (for ARC), and plugged into that via HDMI are:
- OG Xbox One
- Nintendo Switch
- Wii U
- Uverse Cable Box (this only does compressed 1080i, which sucks, but I don't base calibration on it so...)
A non-Ultra Chromecast is plugged into HDMI2, because I wasn't a fan of the built-in SmartCast.
For both TV inputs, I have the following calibration settings (with one difference):
Picture mode: Custom
Auto Brightness Control: Off
More Picture menu:
Color Temperature: Computer
Black Detail: Low
Active Full Array: Low
Reduce Judder: 0
Reduce Motion Blur: 0
Clear Action: Off
Reduce Signal Noise: Off
Reduce Block Noise: Off
Game Low Latency: On (off for CC)
Film Mode: Off (on for CC)
Color Space: Auto
The biggest concern I have is motion/frame processing/whatever it may be called. One caveat -- I absolutely must have GLL on, since the difference is night-and-day, but that poses a problem with using the Xbox for watching Blu-rays because I feel like part of the framey-ness comes from that setting. I don't want the soap opera effect/interpolation, but as it stands now, it just looks... choppy, in a way? Kind of smeary, as well. I can't quite put my finger on it.
Having the Chromecast on a different TV input works as sort of a "control" in my experiments to fix the problem. I thought maybe it had to do with going through the receiver, but nope -- the Chromecast does the same thing. I don't even think using Film Mode instead of GLL really solves it 100%.
Things I haven't tried: a new HDMI cable. I think the one I'm using from receiver to TV is pretty old. But an HDMI cable is an HDMI cable, so I've heard. It could help with the next problem:
Using the Chromecast, I'll get an audio cut-out every ~10min or so. This is likely due to ARC, which may be solved with a new HDMI cable *or* running an optical cable instead. Not sure.
I haven't tried using HDMI5 for 120Hz, either, mainly because I would also need to run optical for the Chromecast.
Finally, I notice the Active Full Array working in some scenes, though mostly with credit rolls. White text scrolling will appear to blink. Not a huge deal, and probably just part of not having enough zones. Comes with the territory, I guess. I don't really want to turn full array off, because I really like the contrast and black level it grants, but I think anything higher than "Low" still won't solve this (and presents other issues, I think).
Looking forward to diving more into this thread!
