    How can I tell if the native input is 720 or 1080?
    Community Answer
    You should be able to find the native input resolution with a Google search of your TV model number. If your TV is a more recent model, chances are it's 1920x1080 pixels.

    If I am watching a movie made in 1935 on an HD TV, will the movie show in HD?
    Community Answer
    It depends. If the movie in question was filmed using film, the resolution can be extremely good. It also depends on the medium: is it Netflix? Is it Blu-Ray? Is it a DVD?

    After the HDMI cord is plugged into my old TV, where does the other end of the cord go on the cable box?
    Community Answer
    It should go on the back of the cable box next to the other outputs. If it's old, it might not have an HDMI output.

    Look for descriptions that include the following: HD Ready, 720P (progressive scan) and 1280 x 720. For the higher resolution HD, look for Full HD, FHD, 1080i (interlaced scan), 1080P (progressive scan) and 1920 x 1080. The newer, 4K displays have 4 times the picture resolution of the FHD types and are often listed as UHD (Ultra HD), 4K, 2160P and 3840 x 2160. The very newest, most expensive displays are 8K and have 16 times the picture resolution of the FHD types; they are designated as 8K, 4320P (progressive scan) and 7680 x 4320.
