Ive recently purchased a JVC HV-28P37 TV to replace an old 4:3 21 Sony. The freeview picture on the Sony via my Humax F2 FoxT was OK but on the JVC Im getting a lot of annoying artefacts on moving images, especially when watching sport. Ive checked the signal strength on my Humax and it read 67% analogue and 100% digital. Ive tried the STB in both RGB scart sockets and Ive also upgraded my scart leads but this hasnt improved matters. I can change some of the feature settings on the TV but this tends to result in a softer picture. Do some STBs handle artefacts better than others? Is there anything I can do to improve the picture quality?
