A:Answer No matter what cables you have or don't have, you cant get 4K from Time Warner. For that matter you also can NOT get 4K service from Dish, Charter or even DIRECTV. DIRECTV is working on it and will be the first to offer 4k. Next would be Dish. But with cables the Time Warner uses along with Charter and AT&T you will NEVER be able to get 4K service. If you doubt me, just call any of those company's and ask for yourself, They will beat around the bush but the answer will be just as I told you. Good Luck
