What are Video Walls?

A video wall is a multi-screen display created by tiling monitors, TVs, or projectors together into a single large screen. The individual screens can display separate content or coordinate to show one image.

Components of Video Walls

  • Display Panels - The LED, LCD, or other screens comprising the wall. Available in various sizes.
  • Video Wall Controller - Distributes input signals across the panels.
  • Mounting System - Hardware for installing panels on walls or structures.
  • Cabling - Connects panels to controller and input sources.
  • Software - Calibrates screens and manages content.

Types of Video Walls

  • LCD Video Walls - Budget-friendly indoor option, but with visible bezels between panels.
  • LED Video Walls - Offer better image quality and energy efficiency. Used indoors and outdoors.
  • Projection Video Walls - Converged projectors to create one seamless image.
  • Custom Video Walls - Mix various screen sizes and layouts for artistic effects.

Common Use-Cases

Video walls are ideal for:

  • Control rooms - With high-definition displays for monitoring data and visuals.
  • Retail spaces - Creating engaging, immersive experiences for customers.
  • Large public venues - Captivating audiences with cinema-scale visuals.
  • Corporate lobbies - Making a statement and wowing guests.
  • Sports stadiums - Enhancing the fan experience with replays and statistics.
  • Museums - Bringing exhibits to life with vivid imagery and informational displays.
  • Events - Communicating with large crowds in venues like convention centers.
  • Broadcast studios - Providing flexible display solutions for production.

What’s a Projector?

Projectors are display devices that use a bright light source and lens system to project video, images, or data onto a viewing surface. Unlike static displays like monitors or TVs, projectors create an image by casting it onto a screen or wall.

There are two main types of projector technologies:

  • DLP (Digital Light Processing) - Uses a chip with microscopic mirrors that reflect light through a color wheel to produce the image. Known for sharp, high-quality images ideal for text and details.
  • LCD (Liquid Crystal Display) - Works by shining a light through a small LCD panel to produce the image. Provides vibrant, saturated colors at budget-friendly price points.

Components of Projectors 

  • Projector Unit - Projects images onto the screen or wall.
  • Projection Screen - Display surface designed for projected visuals.
  • Mounting Hardware - Ceiling or shelf mounts to position the projector.
  • Lens - Controls zoom and focus.
  • Remote Control - For power, settings adjustments, etc.

Common Uses

Projectors are often used in:

  • Live events
  • Home theaters
  • Conference rooms
  • Classrooms
  • Temporary setups like outdoor movies
  • Business presentations

Portability, easy setup and tear down make projectors a versatile choice for both permanent and temporary displays across many environments.

Video Wall vs Projector: Key Factors to Consider

Selecting the right display technology depends on understanding the core capabilities and limitations of each option. From visual impact to practical considerations, here are key factors AV experts evaluate and how they stack up against each other.


Both video walls and projectors have different price points and ongoing costs.

Video Wall Costs

Video walls need a significant initial investment. The cost can vary based on the type of display, number of panels, and complexity of the setup. 

Projector Costs

Projectors are generally less expensive upfront but can incur additional costs for bulbs and maintenance.

Space Requirements

The amount of space you have directly impacts your choice between a video wall and a projector. 

Video Wall Space

Video walls need a large, unobstructed wall space for installation. The size of the wall depends on the number of panels and their arrangement. 

Projector Space

Projectors require less wall space but need room for the projector unit itself, which must be placed at a distance from the screen.

Image Quality

Factors like resolution, brightness, and contrast ratios play a significant role in the final visual experience.

Video Wall Resolution

Video walls have high resolution and pixel density, ensuring crisp and clear images. The quality stays consistent even when viewed up close. 

Projector Resolution

Projectors have varying levels of resolution, from HD to 4K. However, image quality can degrade if the projector isn’t properly calibrated or ambient light interferes. 

Flexibility and Scalability

Your future needs are just as important as your current ones. The ability to adapt or expand your display setup is another key aspect, especially for businesses that anticipate growth or changes in use.

Video Wall Flexibility

Video walls offer a high degree of customization. You can add or remove panels to fit your specific needs.

Projector Flexibility

Projectors are portable and easier to set up, offering flexibility in different types of spaces. 

Power Consumption

Energy efficiency might not be the first thing on your mind, but it can have long-term implications on operational costs.

Video Wall Energy-Efficiency

Video walls use more power than projectors, especially when running for extended periods. 

Projector Energy-Efficiency

Projectors, particularly laser variants, are more energy-efficient. 

Maintenance and Downtime

Being aware of the upkeep involved—whether it's software updates for a video wall or bulb replacements for a projector—can influence your choice and your long-term satisfaction.

Video Wall Maintenance

Video walls are designed for long-term use and require minimal maintenance. 

Projector Energy-Efficiency

Projectors need regular upkeep, including bulb replacements and recalibrations. 

Video Wall vs Projector: Pros and Cons

Every technology has its own set of advantages and drawbacks, and display solutions are no exception.

Pros of Video Walls

  • High resolution and image quality
  • Customizable and scalable
  • Long lifespan 

Cons of Video Walls

  • High initial cost

  • Higher power consumption 

Pros of Projectors

  • Lower upfront cost
  • Easy to install and move
  • Lower power consumption

Cons of Projectors

  • Lower lifespan
  • Susceptible to ambient light
  • Regular maintenance required 

FAQ about Video Walls and Projectors

Can Video Walls Be Used Outdoors?

Yes, certain types of video walls, particularly LED ones, are designed to withstand outdoor conditions. However, it's crucial to consider factors like weather resistance and brightness levels when choosing an outdoor video wall.

How Portable Are Projectors?

Projectors are generally more portable than video walls, especially models designed for mobility. This makes them a versatile choice for events or settings where quick setup and teardown are essential.

Which has a longer lifespan: video wall or projector?

Video walls generally have a longer lifespan, often exceeding 50,000 hours of use. 

Final Thoughts 

There’s no universal answer to the video wall vs projector dilemma. The best display solution depends on the goals, space, budget, and needs of each unique project.

Video walls offer expansive, cinema-quality visuals perfect for engaging audiences in retail, events, lobbies, and beyond. Their seamless screens and reliable performance are ideal for permanent installations.
