Since the standard mode (default) is really bad, you have to read this thread and get some decent picture settings. The trick is to turn OFF the LED motion plus and the Motion Lighting, and turn down sharpness. I don't know why Samsung would provide default options that actually degrade the picture (since they make motion flicker). TURN THEM OFF. Most people would probably just upgrade since they don't read forums BUT if you adjust the settings I think you can have the picture quality of a much more expensive panel.
I ended up with a "CH01" panel and quality seems good but then I haven't seen a "TS01" panel.
