If you want to upgrade your TV and home entertainment setup, consider buying quality used equipment, which will save you money.
A basic home entertainment system requires an HDTV, AV receiver, a DVD or Blu-ray disc player, a sound system, and a media streamer. The receiver acts as the centerpiece of the home theater, providing the connectivity to the rest of your video and audio components, including your TV, gaming console, speakers, set top box, and other equipment.
Most used TVs come with HDMI ports that connect to the AV receiver's HDMI video inputs. This allows you to view videos and images on the TV screen from all video source devices connected to the receiver. The same applies to Blu-ray and DVD players with HDMI connections. If a player doesn't have HDMI outputs, you can use a different output in combination with digital coaxial cables from the player to the receiver.
When choosing used flat screen TVs for your room, it's important to know where you'll place the TV. The farther you are from the screen, the less your eyes can tell the difference between 720p and 1080p resolution. What's more, if you'll be sitting close to the screen, then a 60-inch size is too large for your eyes to absorb, but if you sit really far from the screen, you won't enjoy the visual quality of true 1080p video. Choose a TV that's suitable for the size and sitting arrangement of your living room. Check out our Television Buying Guide for more information.
