Your source has to be providing 4k signal. Any cable will transmit the 4k signal, better cables have less signal loss but should not change the resolution.
Sorry, there was a problem. Please try again later.You would need to connect a 4K capable video source the to TV such as a game system, Blu-Ray player or streaming device. Once you have a 4K source or movie playing the TV will automatically display a 4K resolution. If you have any questions please give our customer service a call at 877-878-4946.
