Seating distance is ~ 1.5 screen width, screen is 200 cm wide. Scaling is being done by the video card. Other animation movies similar to the Simpsons don´t show this kind of ringing on my fp. My money is on the software decoders introducing the ringing for an unknown reason.
As strange and unlikely as this may sound but can there be some thruth behind this statement. Is it possible that the Simpsons BD release uses certain AVC parameters (due to the special content - almost like cell animation) for the encode that causes ***SOME*** decoders to introduce these artifacts???
About the "software decoder" comment - All I can vouch for is that with a PS3 (->software decoder) the excessive ringing is VERY obvious and it is NOT introduced by my setup per se (ergo: not a single other title ever shows ringing caused by my setup - not even test charts). This is also with pixel-to-pixel mapping -> 1080p chain -> no scaling involved.
Is there anybody who uses hardware decoding (STB BD player) and a native 1080p display and in fact does see excessive ringing??? Which player is it?
Or asked the other way round - is there anybody with software based decoding (HTPC solution, PS3) and a 1080p display and doesn't see any ringing? Which codec exactly?
We just have to clarify this...
