How do I hide cables for a clean digital signage setup?
Simple solutions for hiding cables
The easiest way to hide cables is to use cable raceways—plastic channels that stick or screw to the wall and can be painted to match. They're cheap ($10–$30 for a kit) and available at hardware stores. For a slightly nicer look, use a cable management box behind the screen to coil excess cable. If your screen is on a stand, you can often route cables through the stand's channel.
Another option is to use flat HDMI and power cables that can run under carpets or behind baseboards. These are thin and paintable, but check local electrical codes—you shouldn't run standard power cables under carpets or through walls unless they're rated for in-wall use.
- Cable raceways: paintable and easy to install.
- Cable ties and adhesive clips: good for behind furniture.
- Flat cables: run under rugs or along baseboards.
- Cable management box: hides power strips and excess cable.
Professional in-wall installation
For the cleanest look, run cables inside the wall. This requires cutting drywall, drilling through studs, and installing electrical outlets behind the screen. If you're not comfortable with electrical work, hire a licensed electrician or low-voltage installer. They can also install a recessed media box that holds the player and power supply out of sight.
In-wall installation typically costs $150–$500 per screen, depending on wall type and cable length. It's often worth it for customer-facing areas where appearance matters. Always use in-wall rated cables (CL2 or CL3) to meet fire codes.
Common mistakes
- Running standard power cables inside a wall without proper in-wall rating—this is a fire hazard.
- Using cheap adhesive clips that fall off and leave cables dangling.
- Forgetting to leave a service loop so you can pull the screen out for maintenance.
