I have just acquired an LG RZ42PX12X plasma screen. I connected my Sky digital box to AV1 via Scart and my DVD to AV2 via Scart Although the DVD picture is fine the picture displayed from Sky is very grainy and boxy. I understand this due to the way the Sky signal is compressed. I have overcome this problem on several rear projection TVs by activating RGB. However none of the Scarts on this new LG RZ42PX12X seem to be marked RGB. I have been told by a friend that to considerably improve the picture I should connect the Sky Digital box to the screen using a Scart to RGB & Audio Cable like this QED one .. http://www.qed.co.uk/cables/sqart/av19.html The TV has the necessary RBG component connections but will this £50 cable make the sky digital any better??????
