Hi, i've just got a 434hd after 'upgrading' from a panny 4 series. The pic quality is, i'm sorry to say, is worse than my old plasma. I'm using Sky connected with Qed squart, HK 30 with Qed component. Am i missing some thing cause i thought the pio would be a better disply being a higher res. Also i know the fan noise is slightly noticable but occationally it makes a noise like a hard drive from a computer is this normal. I made the change mainly due wanting a plasma that should last for a while ie hdmi & HD res, any advice in setting it up pleeze. PS. Also is it possible to adjust screen with & depth, not just move the position of screen in the set up menue, as according to the THX calibration discs it needs to.
