Loving my P605 so far. All the posts here have been very helpful in optimizing my settings for my living room.
One thing I noticed that has been observed in prior posts, is that the Sharpness setting seems to jump all over the place. I haven't yet been able to nail down the exact circumstances, but so far:
1. When the TV switches into HDR10 mode, the Sharpness seems to jump up to something like 50+. This seems to happen regardless of whether I have it set to 0, 1 or 20 (simply as a matter of testing to see if it would make a difference.
2. Oddly, it seems to happen when I switch inputs as well, without any HDR/DV mode switch. Just tonight I flipped to my PS4 Pro, and noticed that the picture looked odd. Sure enough, even though the UI showed Sharpness at 20, it was actually much higher.
In these cases, simply changing Sharpness up or down by one, then changing back, corrects the problem. It is, however, extremely annoying to do this.
I was wondering if anyone has stumbled across a fix for this, or if waiting for a firmware update is the only option. -_-
