She actually put on her glasses because she thought it might be her eyes, and I took out my contacts and put on my glasses, because I though it might be my contacts.
I keep trying to figure out what is causing it. When I look at static lettering on the Directv guide on with titles, they appear quite sharp. And when people are not moving on the screen or there is a still scene, I don't seem to notice it. Perhaps it seems to occur primarily with motion? Is the motion processing not as good as on the plasmas? Is this something that gets better after the set has a few hours on it, or should I be turning on Tru-motion to some setting?
Motion on both OLED and LCD will never be as good as Plasma (let alone CRT) because of inherent limitation to the technology (look up "sample-and-hold" if you want more details).
The TruMotion settings help but they all have their drawbacks, and effectiveness varies depending on the content:
-De-blur: only works for 60fps content (mainly video games, some video content), overall good at reducing blur in motion, but can produce weird artifacts in the picture because this is essentially creating frames that don't exist to smoothen your perception of motion ("frame interpolation"). Might as well keep this at 10.
-De-judder: only works for 30fps content (pretty much all TV shows), is prone to introduce a lot more artifacts (because more fake frames are being made up), and generates the "soap opera effect". If you can tolerate it, try low settings.
-MotionPro: also called black-frame-insertion/flicker, pretty good at approaching the motion resolution of an impulse-based display like Plasma (though not as good as CRT), but basically halves the brightness of the picture, and the flicker may be noticeable in some content/for some people.
Basically it's all compromises.
Regarding picture softness, that is likely to be the case with sub-4K resolution content. As pointed out, no OLED has been good at upscaling (not even Sony's), just acceptable at best. The screens are just too big, even at 55 inches, for 780p/1080i and below. A setting sharpness of 0 for such content is not appropriate though. The standard seems to be 10, but no one is sure, some say 20. I'd say 1080p looks very good in this set, but anything lower is bound to disappoint and will look vastly better on a smaller LCD/Plasma/CRT.
