I often wonder about Sky “broadcasts” (if that’s the right word) in that they appear, at least to me, to being over-processed, and not unlike how TV screens look in dealer showrooms. Everything colour-wise just screams at you. In a dimly lit room it can be unbearable.
At my girlfriend’s house, she often switches to terrestrial for a more naturally satisfying picture if available on the same channel, so it’s not “just me”. Yes l reset her TV menus. Thinking now, l never have looked to see if the Sky Box can be manually adjusted…. Time to investigate!
