Yes, you can connect your cable TV to an Epson projector. However, there are a few things to straighten out. 

Modern TVs have HDMI output ports that allow you to connect them to another display device. You can send video signals from your TV to the Epson projector via HDMI. 

However, this is a three-step connection: Cable box — TV — Epson projector. It also means that you will have two displays instead of one.

The best way to watch cable TV on your projector screen is by connecting the cable box directly to your projector.

A cable box is a device that allows access to encrypted channels on television satellites. It unscrambles digital TV signals before it sends them to your television or projector.

Cable boxes and Epson projectors often come with several connectivity options. Keep reading to discover the different ways to connect cable TV to your Epson projector.

Connectivity ports determine how data is exchanged between devices. You need to connect your projector and cable box via the right ports.

There are several connectivity ports on the Epson projector. The HDMI connector is the most important of them.

Invented in 2002, HDMI is the standard for modern video devices. It transmits high-quality digital audiovisual signals. 

If you want to watch Cable TV in HD or 4K, HDMI is the best connector for you. 

Cable boxes manufactured in the last decade come with HDMI ports that allow you to connect one directly to your projector.

Below is a list of all the connectors you can use to set up cable TV.

On a cable box:

  • HDMI port
  • Composite AV ports

On an Epson projector:

  • HDMI port
  • DisplayPort
  • DVI-D

Step 1: Locate the Composite AV ports on your cable box and Epson projector. They are usually colored yellow, white, and red. 

Step 2: Plug one end of the composite cable into the cable box. Match each plug to the port with the same color.

Step 4: Connect the projector to a power outlet and power it on.

Step 5: Press the Source button on your projector’s remote repeatedly until the display is set to ‘Video.’

If we lived in a perfect world, you would skip this section. However, the world is far from perfect, and sometimes the connector ports on your devices don’t match. 

If your Epson projector is an old model without HDMI, how do you connect to your cable box with HDMI?

All you need is an adapter/converter. 

Adapters allow you to connect otherwise incompatible devices. They connect to the available port and provide the required connector.

If your projector doesn’t have an HDMI port, you may need one of the following:

Steps to connect your devices with an adapter:

Step 1: Purchase an adapter that converts from HDMI to a connector on your Epson projector (VGA, AV, DisplayPort, etc.).

Step 2: Buy a cable that matches the output connector on the adapter (VGA, AV, or DisplayPort). 

Step 3: Plug the HDMI end of the adapter into the HDMI port on the cable box. 

Step 4: Plug one end of the cable into the adapter, and plug the other end into your Epson projector.

Note: Usually, the adapter’s HDMI connector is male (plug-in). However, use an HDMI cable to connect the adapter to your cable box if it is female.
