Sorry, there was a problem. Please try again later.Not dumb at all. The HDMI ports on the very back of the TV are best used for non 4k devices such as DVD players, standard blue ray players or a Playstation3. The ports on the side should be used for UHD 4K players or 4K Roku sticks. But you should also purchase a 4K HDMI cable for those devices as well.
