Hi, recently bought the above due to the AWFUL pics on my pw7 coming from sky. I 'temporarily' connected the box to the VGA input using a borrowed computer cable from work. Now, Im no whatever-o-phile but was rather disappointed, even though the cable may not be reccommended for the job. IF I go for a 'reasonably' priced cable will I notice a great improvement (if so any suggestions?) as if not I will stick to the connection Ive got. Thanks.
