This is my first time picking up a TV and it was so easy to install. Just use the rod finder to make sure you don't have a blockage preventing you from slipping your lines into the bottom hole. The box looks a little big but is completely hidden by our 50" TV. We have two HDMI cables and I don't think you can run much more than 3 through the bottom hole. You will need the plastic for more than three cables adjust and trim. Or run an HDMI and use the HDMI switch box to connect the rest of your HDMI cables - then no problem. Make sure your HDMI cables are long enough so you don't have to try to use a new one after you're done. Set up. It's so easy to install. Watch the video uploaded by the manufacturer on this listing and you'll be fine.
