For the uninitiated, an HDMI port looks like this.

Step 2: Connect the HDMI Cable
Once you locate the HDMI ports on the projector and the cable box, it’s time to connect them through an HDMI cable.
You may have an HDMI cable lying in your house. It’s because most projectors and cable boxes come with an HDMI cable.
If you’re missing an HDMI cable, you can buy one for cheap on Amazon. Since we’re talking about connecting the cable box to the projector, you’ll also find HDMI cables up to 50 ft. in length.
Step 3: Power ON the Projector & Cable Box
After connecting both devices with an HDMI cable, it’s time to check the connection. Power on both devices and let them go through their boot-up process.

7 Tips for Optimal Cable Box & Projector Setup
- High-Quality HDMI Cable: A high-quality HDMI cable will transfer video and audio signals much more efficiently than a cheap one. A cheap HDMI cable will result in noisy picture quality and weak sound quality.
- Right-size HDMI Cable: Along with the HDMI cable’s quality, it’s also important to get the right length HDMI cable. Unlike a TV and Cable TV connection, a projector will sit far away from the cable box unless you have a UST projector. You’ll find 50 ft. HDMI cable for less than $30 on Amazon. In addition, ensure the cable has ample slack to count any last-moment adjustments.
- Using external speakers: Like TVs, most projectors have poor built-in speakers. As a result, it is a wise decision to invest in an external speaker system or sound bar. More importantly, you can connect the speaker system to your cable box or the projector thanks to the flexibility of HDMI technology.
- Use a projector screen: No matter which projector you buy, it performs well on a projector screen. Thus, if you plan to use it on your wall, I’d recommend against it unless you’re using projector paint on the wall.
- Dim the room: Unsurprisingly, a projector works best in a dark environment. Therefore, make sure to make the room as much dim as possible. In a darker environment, you can use the projector in Eco mode, which helps save extensively on electricity bills.
