Can a Computer Monitor be Tracked?

It is a common question: can a computer monitor itself be tracked? The short answer is, generally, no, a monitor does not have inherent tracking capabilities. However, there are several contexts and methods in which a monitor can be indirectly tracked. This article delves into the specifics, exploring the various ways in which monitors can be linked to tracking and the security risks involved.

Understanding Tracking Methods

The term 'tracking' can encompass several different contexts. Here’s a breakdown of the methods by which a computer monitor can be compromised:

IP Address Tracking

When a computer is connected to the internet, its IP address can be tracked. This can provide information about the general location of the device but it does not pinpoint the specific monitor. IP address tracking is a straightforward method, commonly used by routers, firewalls, and other network devices.

Device Management Software

In corporate or institutional settings, IT departments can use device management software to monitor connected devices, including monitors. This software can track usage, performance, and even location if the monitor is part of a networked system. However, standalone monitors typically do not have such capabilities unless explicitly configured by IT administrators.

Physical Tracking

Monitors can be physically tracked if they are part of a device that has GPS capabilities, such as a laptop. However, standalone monitors do not usually have GPS features. Additionally, even if a monitor is part of a networked or integrated system, its physical location can be monitored if it is connected to a network that has location services.

User Behavior Tracking

Monitoring software can track user behavior on the computer, including what is displayed on the monitor. This form of tracking is more about monitoring user activity rather than the monitor itself. User behavior tracking is commonly used by IT departments for compliance and security purposes.

Serial Number and Warranty Tracking

Manufacturers often track monitors through their serial numbers for warranty and service purposes. This can provide information about the monitor’s ownership history. While this is a common practice, it does not typically involve active tracking of the monitor's location or usage.

Concerns and Risks

While standalone monitors do not have built-in tracking features, they can be compromised through associated devices, software, and networks. Here are some additional concerns and risks:

Security Risks

No, a ViewSonic or LG monitor does not have the functionality to track itself. However, it can be linked to tracking through software or networks. For example, if the monitor is connected to a network that has tracking capabilities, it can be monitored. Adding a Apple AirTag to the monitor can help in physical tracking, but it is generally better to secure the monitor with a physical locking mechanism to prevent theft.

Historical Context

Way back, spycraft involved surveilling CRT monitors through walls. If you start searching online, you will find fascinating methods used to collect information. For example, monitoring fan noise can be one such method. Interestingly, EM radiation emitted by HDMI cables could potentially be intercepted and converted into signals, similar to how CPU emissions are monitored.

Modern Surveillance

Today, there are significant concerns about the tracking capabilities of modern devices. The firmware and drivers of monitors, CPUs, and other hardware components can be compromised through various means. For instance, it was discovered that UEFI firmware was potentially hacked 10 years ago, unbeknownst to users.

Conclusion

While a monitor itself does not have built-in tracking features, it can be indirectly tracked through associated devices, software, and networks. It is more plausible that a monitor can be tracked than not, given current technological advancements. However, taking appropriate security measures, such as securing the monitor with firmware and physical locks, can significantly mitigate these risks.
