just purchased one of these, looked great in the store, superb picture (shark tale dvd) in store. just some q's though. bad solarisation in certain instances, any advice? active control. on or off? with or without sensor? is it worth buying a converter to use the vga option or should i stick with rgb? using sky digibox, set to rgb and monster scart lead (paid £30 for lead to get £149 table stand for free!). -please advise if you can.
