How to stream HDMI or VGA over LAN without using video extenders?
HDMI over LAN technology enables the extension of a PC’s desktop through a local area network (LAN), using standard Ethernet rather than direct HDMI connections.
This setup allows displays to be positioned at considerable distances from the source computer, providing greater flexibility in managing multiple screens across large areas. Originally developed to share USB devices like printers and storage, AV over IP now supports a wide range of audio-visual signals, making it ideal for complex environments such as digital signage, corporate video walls, or command centers, where scalability and high-resolution content are crucial.

The Requirement
To connect multiple screens in a building or a campus to a single PC over the existing LAN, to push a different content on each screen or to clone the same content on all screens. Also, to have the option to create a video wall from a large array of screens.
The Solution
In today’s high-speed LAN environments, AV over IP technology facilitates the seamless connection of multiple screens over a single network. Also known as ‘HDMI over LAN’ or ‘DVI over LAN,’ it supports HDMI, VGA, and DVI connections.
MAWi utilizes this advanced technology to make digital signage simpler and more cost-effective. With a single PC and LAN connection, you can distribute content across several screens effortlessly.
Moreover, when paired with Zero clients or MAWi Players, our technology overcomes distance limitations, providing increased flexibility and scalability for deploying digital signage solutions.
Use cases
With MAWi, you gain full control over the content displayed on every screen connected to the main computer. This powerful software enables efficient management and customization of the content across all screens, ensuring a seamless and tailored digital signage experience.
Leverage the capabilities of HDMI over LAN zero clients to achieve diverse content distribution on individual screens, configured as multiple extended desktops, or effortlessly create remote video walls. This innovative solution empowers you to tailor and control the content displayed on each screen, enabling flexible and dynamic digital signage configurations.
Another option is to mirror the content of the PC screen onto numerous monitors or TVs; you can also create multiple cloned groups that show different content in perfect sync.
How does it work
In the following videos you can see some examples of how to utilize HDMI over LAN zero clients with MAWi.
Many names – same solution
Different hardware manufacturers are developing the same solution under different names.
Some of the names you might see in the market are: VGA over LAN, Zero Clients over LAN,AV over IP, VGA over IP, VGA over Ethernet, HDMI over IP, HDMI over LAN, HDMI over Ethernet, IP 2 VGA, PC 2 HDMI, VGA via IP, HDMI via IP, HDMI 2 IP, DVI over Ethernet, AV over Gigabit Ethernet, PC to HDMI over LAN, VGA on LAN, VGA to LAN, etc…
Either way it’s cost-effective, and easier to install and maintain than using video extenders.
How to Share Your Screen Over LAN to a TV
Sharing your computer screen over a local area network (LAN) to one or multiple TVs is one of the most practical applications of HDMI over LAN technology. Instead of connecting every display directly to your PC with long HDMI cables, you can use your existing Ethernet infrastructure to distribute video and audio across your network.
The process is straightforward. A central computer sends its display output through the local network, while receivers connected to each TV decode the signal and display the content in real time. Depending on the software and hardware you use, you can either mirror the same screen on every display or assign different content to different TVs.
This flexibility makes HDMI over LAN an excellent solution for organizations that need to manage multiple displays without complicated AV installations.
For example, businesses commonly use this setup to:
- Display company dashboards throughout the office
- Broadcast presentations in meeting rooms
- Show production KPIs across manufacturing facilities
- Deliver digital signage in retail stores
- Display surveillance feeds in security operations centers
- Share training materials in classrooms
Unlike wireless screen sharing solutions, HDMI over LAN offers a stable and reliable connection that isn’t affected by Wi-Fi congestion. Since everything runs through the wired network, businesses benefit from consistent performance even when managing dozens of displays simultaneously.
Another major advantage is scalability. Instead of purchasing HDMI splitters or running additional cables every time a new screen is installed, administrators simply connect another receiver to the network. This dramatically reduces installation costs while making future expansion much easier.
Organizations can also create different display groups. For example, the reception area can show welcome messages, the sales department can display live KPIs, while production monitors show manufacturing statistics—all managed from the same central PC.
If you’re looking for an enterprise-ready solution, see how one PC drives every screen on your network by using Monitors AnyWhere’s HDMI over LAN technology. It allows organizations to centrally manage displays across offices, factories, campuses, and control rooms while using the existing LAN infrastructure.
DisplayPort over Ethernet
Although HDMI is the most widely recognized video interface, many professional computers, industrial workstations, and high-performance graphics systems use DisplayPort instead. Fortunately, the same networking principles apply.
DisplayPort over Ethernet enables DisplayPort video signals to travel across a standard Ethernet network rather than through traditional DisplayPort cables. This allows organizations to overcome cable distance limitations while simplifying installations and reducing infrastructure costs.
Whether the source device outputs HDMI or DisplayPort, network-based display management makes it possible to deliver high-quality video to remote displays across the building using the existing LAN.
This approach is especially valuable in environments such as:
- Network Operations Centers (NOCs)
- Security Operations Centers (SOCs)
- Industrial automation facilities
- Broadcast studios
- Financial trading floors
- Engineering departments
- Corporate command centers
In these environments, workstations often use multiple DisplayPort outputs to support several monitors simultaneously. Rather than installing expensive long-distance DisplayPort cables, Ethernet becomes the transport layer for distributing visual content.
DisplayPort over Ethernet also provides greater flexibility when expanding a deployment. New displays can be added without redesigning the entire AV infrastructure, making it easier to grow from a handful of screens to hundreds of endpoints as business needs evolve.
Another important benefit is centralized management. Administrators can monitor, configure, and update displays remotely, reducing maintenance time while improving operational efficiency. This is particularly valuable in organizations with multiple buildings or distributed facilities.
Businesses looking for even simpler deployments often combine HDMI over LAN or DisplayPort over Ethernet with dedicated zero-client hardware. Instead of placing a full computer behind every screen, a compact receiver connects directly to the network and receives content from the central management platform.
For organizations that require secure and reliable endpoint devices, consider a zero-client setup with MAWi Zero, which eliminates the need for traditional PCs while maintaining excellent performance and simplified management.
Real-world deployments demonstrate just how scalable this technology can be. For example, Monitors AnyWhere technology was used during the Rakia Space Mission Control Center to drive multiple displays over the network in a mission-critical environment. You can see 8 screens driven over LAN in a space mission to understand how network-based display management performs under demanding operational conditions.
As organizations continue adopting IP-based infrastructure for both IT and AV systems, DisplayPort over Ethernet and HDMI over LAN are becoming essential technologies for scalable video distribution, video walls, digital signage, and centralized display management. Whether you’re connecting a few displays in an office or deploying hundreds of screens across multiple facilities, Ethernet-based video distribution offers the flexibility, reliability, and scalability that modern organizations require.
Frequently Asked Questions
What is HDMI over LAN?
