How Do I Connect a Cable Box and Roku to a Single HDMI Input on My TV?

By Chris Boylan

Dear Big Picture Big Sound,

I have 1 HDMI input on my TV which is connected to a cable box. I also would like to be able to connect another device (Roku-3) to my TV but do not have extra HDMI input. Of course I can unplug cable box and connect Roku-3 but it's inconvenient. Is there a device that splits the HDMI input on TV? An HDMI splitter?

Thanks,

Hello, Luba,

Thanks for writing in. We get this question pretty often and first answered it back in 2007: (How Do I Connect Two HD Devices to One HDMI Input on my HDTV?). Eight years later, the answer is still pretty much the same. The item you need is is called an HDMI switch. An HDMI splitter is something different (It allows you to connect one device to multiple TVs), but an HDMI switch will do what you need. These are small boxes that connect to the HDMI port on your TV and allow you to connect multiple HD devices (using HDMI cables) and switch between those sources.

If you need to connect just two devices, you could get a 2-port HDMI switch but we'd recommend getting at least a 3-port switch in case you add something else in the future. There are some really cheap ones out there that typically don't work very well but you can get a decent 3-port HDMI switch for under $30 or a 5-port switch for under $40. Here are a couple that we would recommend on Amazon:

3-Port HDMI Switch (Front and Rear)
An HDMI switch allows you to connect multiple HD devices to a TV with only one available HDMI port (pictures courtesy of Amazon).
These ones come with their own remote control so you can switch between sources easily. They're quite small so you should be able to sit one on top of your cable box with room for the Roku next to it.

Another option you might consider is just using component video/audio cables to connect your cable box to your TV instead of HDMI. If your TV has component video inputs (5 cables consisting of red/green/blue RCA cables for video and white/red RCA cables for audio), you can just buy an inexpensive set of component video cables instead of a switch. Component video supports up to 1080i resolution so you will still be getting a high definition signal from your cable box. This will free up the HDMI port for the Roku streaming box and would not require the purchase of the switch.

Hope that helps!
