How to Hook Up Multiple TVs to One Converter Box

By Jeff Grundy

Most digital cable subscribers only have one converter box in their home. This is because the cable company usually charges a hefty premium for additional boxes. As a result, many subscribers view programming only on the TV connected to the converter box. If you want to unscramble cable signals for other TVs in your home, though, you can do so with an adapter and some coaxial cable. Using an adapter does not allow you to use multiple TVs to view different shows (you need additional converter boxes for that). Still, it does allow you to display the same programming on all TVs connected to the adapter.

Things You'll Need

  • Splitter adapter
  • Coaxial cables

Step 1

Turn off the converter box. Turn off all TVs you want to connect to the converter box.

Step 2

Disconnect the coaxial cable to the primary TV if connected to the converter box. The primary TV is the one connected to the converter box by the cable company when it installed the digital cable system.

Step 3

Connect the coaxial cable from the converter box to the "Video In" port on the splitter adapter.

Step 4

Connect a coaxial cable to the first "Video Out" port on the adapter (Note: The adapter might have more than two "Video Out" ports, depending on the type you purchased). Connect the other end of the coaxial cable to the "Cable In" or "Video In" port on the primary television.

Step 5

Connect a coaxial cable to the second "Video Out" port on the adapter. Run the other end of the cable to another TV in your home and connect it. Connect other TVs to the converter box as needed.

Step 6

Power on all TVs to test the connections. Turn on the converter box.

Step 7

Change the channel on the remote TVs so that it matches the one on the primary television (usually channel "2" or "3"). The cable television content displays on all TVs connected to the splitter adapter.
