I bought a LCD flat screen to replace the old TV in the kitchen at the weekend which is wired up from the Sky in the lounge using the second RF port on the box. The picture quality was not great so I plugged a DVD player in (to test) and the picture was excellent, therefore how can I get a better signal in the kitchen from the lounge using something other than normal Co-Ax cable, how do dixons and currys get the same picture on all there screens in there stores, how can I do this in the home, any advice please?
