Ok. I will try one more time. What you seem to be saying is only a high end PC graphics card can perform 'real' 1080p upscaling to 4k. Are you asserting that all home theater components that feature 4k upscaling functionality are simply processing 1:4 pixel conversion or simple antialiasing/sharpening, or perhaps you are only referring to the 4k TV scaler?
Many of us can't do the tests you are putting forward- for a number of logistical reasons. Perhaps you could explain the discrepancies, or if the English language is a barrier, refer us to online resources that we can evaluate for ourselves?
No one here just *loves* to contemplate newly discovered faults or drawbacks with our very expensive TV purchase. But clear evidence is usually accepted, eventually, with only a small amount of belly-aching.
I, for one, am keenly interested in what the panel actually does to upscale a 1080p signal since that is what I'm feeding it from most sources. If it goes beyond or contrary to what I posted about the Reality Creation process, lets hear it.
Here is some other relevant info I found:
"Sony's 4K X-Reality Pro engine, included in its new 4K TVs, actually consists of three separate image processing chips - one of which contains a database of several thousand image patterns against which lower resolution content is matched.
"It becomes possible to create more realistic and optimal super-resolution by process of analyzing wave form from video signals and increasing resolution of various patterns within picture characteristics, instead of simply interpolating pixels," explained Yosuke Yamamoto, project leader of Reality engine development, in a interview on Sony Asia's website. "This database has thousands of patterns that are available for High Definition (HD), Standard Definition (SD), SD up-conversion, IPTV and so forth."
I also tried to digest these articles - I think it is fair to say that our set is not only 'filling the screen' nor is the processing limited to an interpolation algorithm.
