The Hidden Risks of Running Professional Video Walls on PC-Based Software
Most professional video walls use dedicated hardware and specialized platforms – anything else comes with serious risks. In this post, we’ll walk you through the problems you could face if you stick to native PC software instead.
Can You Run Video Walls on PC Software?
Technically, yes, and many people find it to be more flexible and cost-effective than buying extra hardware. However, this can lead to serious operational issues, especially when the team treats it as simply a desktop running a display (or doesn’t invest in enterprise-grade PCs).
In a mission-critical setting, such as an emergency command center, hardware-based video wall control is the only safe bet, and usually includes:
Video wall processors
Input capture modules/cards
Display nodes
High-speed backplane assemblies
A dedicated control interface
Ultimately, PC-based video walls come with too many risks. Below, you’ll see the six main risks, plus why they pose such a problem in mission-critical AV.
1. Operating System Instability
PC-based systems often rely on a standard OS like Windows or Linux, which generally struggle with 24/7 display operations. These also require regular updates, which might automatically kick in and disrupt the display without sufficient warning.
For example, if a Windows-powered video wall reboots overnight to install an update, your team might have to reset the display the next morning. Plus, fluctuating CPU or GPU load may cause lag or dropped frames that affect all linked displays.
2. Cybersecurity Exposure
PC-based video walls effectively make networked computers the backbone of the setup – which means they inherit the cybersecurity vulnerabilities that dedicated hardware avoids.
Common vulnerabilities here include:
Misconfigured firewalls
Weak/shared passwords
Phishing (still a major threat in 2026)
Companies usually don’t expect their video walls to require extra security, even when someone with access could share any content they want, possibly to a public audience.
Technically speaking, a hardware-based approach doesn’t fix all cybersecurity issues. However, dedicated processors usually have locked configurations and a much smaller attack surface, so the risk is still massively reduced.
3. Single Point of Failure
Video walls only function properly if every screen works in tandem. Even one display crashing or lagging risks cratering the whole installation. Of course, a display can fail for any reason, but the video wall using non-specialized software is playing with fire.
Dedicated systems typically include dual controllers, hot-swap modules, and other features that specifically counter single points of failure. This alone makes them a better choice, especially in a mission-critical environment.
4. Unpredictability
PCs often carry out dozens of simultaneous tasks, even in the background, meaning they share resources. This makes it a lot more likely that sudden spikes in memory usage, GPU saturation, or even temperature could crash the wall.
For example, one PC downloading an update – even if it hasn’t installed it yet – might experience lag due to high disk utilization. This might bring it out of sync with the other displays, especially if there’s no hardware-based synchronization.
5. Ongoing Costs
Many people and businesses choose a software-based approach because it’s cheaper, at least on paper. However, expenses can seriously creep up over time; these include:
Update testing
Hardware refreshes
Software licensing
Driver revalidation
Unplanned downtime
Stronger cybersecurity
Purpose-built systems have longer support lifecycles, especially because they’re doing the task they’re designed to do.
Avoiding the Usual Software-Based Risks
The best way to avoid these risks is to use a hardware-based alternative, as outlined above. It’s really not as expensive as you might think, and it’ll keep your video walls running 24/7 for much, much longer.
The only other way to avoid these risks is to invest a lot in cybersecurity, add redundancies, and use heavy-duty PCs with locked-down operating systems. This is a lot of work, especially for an approach that’s meant to be simpler.
Ultimately, a video wall runs best with purpose-built hardware, such as a dedicated processor or controller. Invest well in these, and your video walls will run continuously and amaze customers, while helping staff in their duties.
