I sell Samsung panels as part of professional AV systems, and with consumer panels it's super important to turn off ALL processing that is done by the panel. Yes under certain circumstances you will see artifacts but that's because there are present in the signal.
Once you get everything turned off you will be much happier with the quality. (Of both still and video signals)
