From my experience working in electronics retail, they really do have bad QC. Put an open-box D8K out on the floor last week and the screen was broken up in to two horizontal sections, and on the top the color looked inverted and had very weird smearing/image persistence issues during any scene with fast motion. And don't get me started on their Blu-Ray players...
