Comparing Hardware vs. Software-Based Video Wall Controllers: Which One is Right for Your Project?

Video wall controllers help combine multiple screens into a cohesive interface, making them vital for any smooth audiovisual setup. But are hardware- or software-based controllers better? This post compares both options to help you decide.

An Introduction to Video Wall Controllers

As stated above, video walls only work with a compatible controller. The main options here are:

  • Hardware-based controllers – No operating system and usually exist purely as chipsets or field programmable gate arrays.
  • Software-based controllers – Run on a computer chassis and can even connect to other applications, such as digital signage.

Both video wall controller types have their own strengths and drawbacks, making it crucial to choose one that fits your AV setup.

Software and Hardware VWCs: A Full Comparison

Comparing software and hardware video wall controllers helps you figure out which one will suit your needs. To an extent, this depends on your specific project. However, you’ll first have to know the differences between these VWC types, including:

1. Latency

With the right infrastructure, both hardware and software VWCs have nearly zero latency. If you don’t have a robust setup, however, software controllers can face minor processing delays.

2. Quality

Hardware-based controllers can generally handle larger-scale displays and perform better in the process. Software VWCs can again keep pace with this with the right system and resources.

3. Reliability

Hardware controllers aim for 24/7 uptime, even in demanding settings such as control rooms. A software VWC might struggle to keep up but can fine-tune its features via software updates.

4. Flexibility

These updates also make software VWCs far more flexible and configurable. Unlike a hardware VWC, for example, they can easily connect to other apps or programs, such as digital signage.

5. Scalability

Hardware VWCs cannot breach their hardware’s limits – but are typically suitable for large-scale projects anyway. Software VWCs can scale up or down, depending on your needs at that time.

6. Cost

Hardware controllers are much more expensive, often because they rely on special components to do their job. Software solutions have a lower initial cost, making them more accessible.

7. Usability

A software-based video wall controller usually requires setting up and configuring, but hardware equivalents are “plug and play,” allowing you to get to work immediately after installation.

How Different Controllers Fit Different Projects

A software-based VWC’s flexibility makes it ideal for AV setups that change in scale. If your project is short-term or small, investing in a hardware-based VWC may not be cost-effective.

For some projects, a video multiviewer might even be more appropriate.

Ideal use cases for software-based VWCs:

  • Digital signage displays, which seamlessly integrate with software VWCs.
  • Hospitality venues, which also benefit from remote layout management.
  • Corporate meetings, which allow for more interactive presentations.
  • Museum exhibitions, which often require custom yet non-live content.

When hardware VWCs are preferable:

  • Control rooms to allow instant updates on a developing situation.
  • Security centers, which need to display real-time security feeds.
  • Live broadcasts, where seamless video switching is essential.
  • Company events with large displays for up to hundreds of people.

With the right infrastructure, however, you could use software-based VWCs for these setups.

Other Tips for Choosing Your Video Wall Controller

Beyond the actual project you’re setting up, your scale as an organization also affects which AV equipment you buy. Small businesses need budget-friendly controllers that allow for future growth.

Your VWC choice goes deeper than a hardware- or software-based solution. You’ll also need to buy from a reputable AV brand. The VWC should also be modern, with innovative features that “future-proof” your purchase for years to come.

This decision requires careful consideration—some companies consult AV experts for weeks before purchasing. Ultimately, however, software-based controllers perform as well as hardware-based ones when your infrastructure scales alongside it.

Conclusion

Choosing the right video wall controller is never easy, but software-based solutions offer nothing less than maximum flexibility. This makes them ideal for projects of all sizes, provided you have adequate AV and computer hardware to match.
