"However, high street stores like John Lewis and Comet, and online retailers such as Amazon and Dixons may sell this 3D TV as the Samsung UE46C8000, Samsung UE46C8000XK or Samsung UE46C8000XKXXU. All these terms refer to the same 3DTV. Although we did not review the 40-inch Samsung UE40C8000 or the 55-inch Samsung UE55C8000, there shouldn???t be any drastic difference in picture performance." . . . . . .
