How much do you care about whether you are viewing content in Standard Definition (SD), High Definition (HD), or Ultra HD/4K? Each version gets successively more expensive to rent or buy, and there are also varying costs for subscription plans. Typically the cost is about one dollar higher for HD versus SD, with an even bigger difference (usually about $2) for 4K/Ultra HD. I don't have a 4K television, so that's not even a consideration for me, but I do have some friends with 4K TVs, and some who will pay the extra money, as well as some who are perfectly content with watching in HD, rather than Ultra HD. Which version do you typically watch, and do you feel the added expense is worth it for higher resolution content?
