hey about tvs,. when you buy them, i forget what itās called. but you can pay them extra and itās kinda expensive but they will come to your house after 3-6 months of you using your tv and āset it upā with a computer etc,. i had this done to my current sony tv,. at first after he finished and left and showed me my setting and the new setting i could see a difference but thought mmmm doesnāt seem worth it, after an hour or so watching well that changed, my tv detail and colour everything is outstanding absolutely perfect, i wouldnāt buy a tv now without getting that extra,.. i still say it too myself years later,..
