A:Answer To get a 4K signal, you need 3 things. A 4K Display (which you have), an HDMI cable, a 4K device, and 4K content. HDMI is the only cable that can transmit a 4K signal, so you'll want to ensure any device is connected with HDMI. You'll also need to make sure that any devices you have connected are capable of sending a 4k signal. To ensure you're device is capable of 4K, check the 'Resolution' for that device on the manufacturers tech specs. You'll also need to make sure the content you're watching is in 4K. Some older shows were filmed in SD (480i) or HD (720P or 1080I). These shows won't be in 4K because they're not filmed and transmitted that way. You can usually check with the content provider (the app you're using or your cable company) to ask them what content they have available in 4K.
