Click on the thumbnail image with "+7 images" on it to open another page of thumbnail images for the LG 49 inch Class 4K Smart UHD TV w/AI ThinQ® (48.5'' Diag) , Model # 49UM7300PUA on its product page on Best Buy. Then click on the third thumbnail image down from the top in the right-hand column of images to see the ports on the back of the TV. The port in the back is what is referred to as a 'Shared Composite/Component Video port'. The way the shared input works is that the TV's video input circuitry has been modified so that both a composite and component video source connection (and associated analog audio input) can be accommodated. However, there is a catch — with this type of "shared" configuration, you can't plug in both a composite and component video signal source (with associated analog stereo audio) to the TV at the same time. What this means is that if you have a VCR, older camcorder (composite video source) and an older DVD player or cable box (component video source) or a Wii, you can't connect both of them in at the same on a TV that only provides a shared composite/component video connection. In almost all cases, TVs with a shared composite/component video connection only provide one set so you can't plug two units in at the same time...^IFV
