All of the HDMI ports on the LG UK6300PUE 4K HDR Smart LED UHD TV w/ AI ThinQ® - 43'' Class (42.5'' Diag), Model # 43UK6300PUE are HDMI 2.0 ports and they are all HDCP 2.2 compliant. If the HDMI ports are not connecting after you turn your TiVO devices on, you may be having issues with the HDCP 2.2 handshake between the TV and your TiVO devices. Digital Rights Management (DRM) protocols are protocols designed to protect content creators and distributors against piracy. HDMI’s DRM protocol is known as High-bandwidth Digital Content Protection. The protocol was developed by Intel and is used not just with HDMI but a variety of digital video standards like DisplayPort and Digital Visual Interface. It provides for an encrypted connection between a content outputting device (like a Blu-ray player, cable box, streaming stick like the Chromecast or Roku Stick) and a receiving device (an audio-video receiver in a media center setup or the HDTV itself). HDCP is everywhere and is built into devices like Blu-ray players, cable boxes, satellite TV receivers, and streaming video hardware like the Chromecast and Amazon Fire TV. It’s also built into laptops and computer hardware, DVRs, and other modern HDMI devices. Although the underlying encryption and protocols are sophisticated and outside the scope of this response, the basic premise of how HDMI HDCP works is quite simple. There is a licensing body that issues licenses for HDCP devices. Each HDCP compliant device, like your Blu-ray player or Xbox, has a license and the ability to talk to the device it is outputting the signal to over the HDMI cable. Your TiVo devices say “Hey display! Are you HDCP compliant? Here is my license, show me your license!” and in turn, the display (or other HDCP compliant device) returns with “I am! Here is my license!” When that process is working, it happens within a thousandth of a second, and you, the consumer, never even notice. You power on your TiVO devices, Blu-ray player, or DVR, it makes nice with your HDTV, and you live a happy life never knowing what HDCP even is. Unfortunately, however, there are a host of situations where HDCP gets in the way of consumers doing perfectly legal things with their devices and content. If any device in the chain is not HDCP compliant, the video stream will fail. The only way to deal with the issue that you're experiencing is to buy an HDMI splitter that ignores HDCP requests. To use the splitter, simply put it between the device(s) giving you the HDCP error and the display device. Problems with Video or Audio on your TV caused by HDCP handshake issues rarely occur when all sources, HDMI distribution equipment, and displays are always powered on 24×7. Since we do power-off displays and source devices most issues occur when these devices are powered on again to re-negotiate the HDCP handshake between source and display. There is a recommended power-on sequence if you regularly power cycle your equipment. There are often handshake issues simply due to a poor connection. Even if the HDMI cable fits securely please ensure that there are no sharp bends of the cable or the cable is causing the hdmi port to bend. When a HDMI / HDCP Handshaking issue occur the easiest way to re-negotiate the handshake is to power cycle the source device or the display. Always wait 10 seconds or longer when the display or source has been power cycled for the HDMI distribution equipment to reset HDMI handshake/timing. Some displays may also re-negotiate the handshake when swopping to another input e.g. HDMI 1, HDMI 2 or another HDMI Port (wait 10 seconds) and swopping back to correct HDMI Input via remote control. HDMI Distribution equipment should never be powered off since it provides the path for the HDCP / HDMI Handshake between source and display. Some devices such as switches and HDMI Switches / Combo splitters also allow for HDMI handshake re-authentication by switching from one input to another and back to the input having HDCP handshaking issues. If power cycles on the Display or Source do not prove to be an effective method, power cycle all HDMI equipment (Source, HDMI Distribution Equipment, Receivers / Amplifiers, and Displays). If HDCP errors still occur you need a firmware upgrade to sort out the HDMI port timing/handshake issues on the source or display. Please contact your Source device, Display or Digital receiver manufacturer for a firmware upgrade and advice on HDMI handshake issues...^IFV
