Wi-Fi in a Monitor: Why You Need a Wireless Module and How to Use It

When choosing a new monitor, you suddenly notice in the specifications the line “Wi-Fi 5/6" or "wireless connection" - and you ask yourself: why at all? monitor Built-in Wi-Fi? After all, this isn't a smartphone or laptop, where wireless connectivity is obvious. In practice, Wi-Fi in monitors solves several problems at once—from simplifying connectivity to expanding functionality to the level Smart TV.

In this article we will look at 5 real-life scenariosWe'll explore where Wi-Fi in a monitor is useful (and where it's indispensable), compare the pros and cons of these models, and explain how to properly configure the connection to avoid lag and compatibility issues. We'll pay special attention to hidden functions, which manufacturers often keep silent about—for example, using the monitor as a secondary screen for a tablet or broadcasting game consoles wirelessly.

Spoiler: If you plan to build a multimedia system, stream content to 4K HDR or connect the monitor to Apple AirPlay Wi-Fi will become your main assistant. And if you only need an office display for working with documents, there's no point in overpaying for a module. Let's explore where that line lies next.

1. Main reasons: why monitors need Wi-Fi

Let's start with the obvious: Wi-Fi in a monitor didn't just appear out of nowhere. Manufacturers seem to LG, Samsung or ASUS They're adding the module not for show, but to solve specific user problems. Here are the key scenarios where wireless connectivity makes sense:

• 🎮 Wireless gaming consoles: connection PlayStation 5, Xbox Series X or Nintendo Switch to the monitor via Wi-Fi instead of HDMI - especially relevant for portable mode Switch or streaming games from PC Moonlight.
• 📺 Smart TV Replacement: viewing Netflix, YouTube or Twitch directly on the monitor without additional attachments (for example, in models with webOS or Android TV).
• 🖥️ Wireless mirroring screen: using the monitor as a secondary display for a laptop, tablet or smartphone using protocols Miracast, AirPlay or Google Cast.
• 🔄 Over-the-air firmware update: automatic download of updates for the monitor's firmware (relevant for models with USB-C and advanced features).
• 🎧 Audio streaming: transmit sound to wireless headphones or speakers directly from the monitor (if it has one) Bluetooth or support Wi-Fi Direct).

But there is a downside: Wi-Fi increases the cost of the monitor by 15–30%, consumes additional power and may cause interference if the router is located far away. Therefore, it's important to clearly determine whether you need these features before purchasing.

2. Wi-Fi vs. Wired Connection: Key Parameters Comparison

To understand whether it is worth overpaying for a wireless module, let's compare it with traditional wires (HDMI, DisplayPort, USB-C) according to the main criteria:

From the table it is clear that Wi-Fi is losing out to wires in terms of performance, but it wins out in terms of convenience. For example, for office work or eSports, a wired connection is better, while for home theater or casual gaming, a wireless one is better.

⚠️ Attention: If you connect the monitor to PlayStation 5 or Xbox Series X via Wi-Fi for gaming 4K@120Hz, be prepared for reduced frame rate (maximum 60 Hz) and possible lags. For a full gaming experience, use HDMI 2.1.

3. How Wi-Fi Works in Monitors: Technical Details

The wireless module in the monitor is more than just an "internet receiver." It can operate in several modes, each serving its own purpose:

1. Wi-Fi Direct: Direct connection to devices (such as a smartphone or laptop) without a router. Used for screen mirroring Miracast.
2. Wi-Fi in client mode: The monitor connects to your home network, just like a smartphone or laptop. This is necessary for streaming content or updates.
3. Wi-Fi in hotspot mode: the monitor itself distributes the network (rarely found, usually in professional models).
4. Dual-band Wi-Fi (2.4/5 GHz): Modern monitors support both ranges for stability.

It is important to understand that Wi-Fi on your monitor ≠ Smart TVFor example, the model LG UltraFine 27MD5KL-B has Wi-Fi, but can't run Netflix by itself - for this you need an external source (laptop, smartphone or set-top box). But Samsung M8 With Tizen OS It's closer to the TV: it has its own streaming apps.

What wireless protocols do the monitors support?

The most common standards are:

- Miracast (built into Windows 10/11, Android) - screen mirroring without additional software.

- AirPlay (for Apple devices only) - requires support from the monitor (e.g. LG UltraFine).

- Google Cast — for broadcasting from Chrome or Android-devices.

- DLNA — a protocol for transferring media files over a local network (for example, from a NAS server).

- Steam Link — streaming games from a PC to a monitor via Wi-Fi (requires a powerful router).

If the monitor specifications state “Wi-Fi 6", this means support for the standard 802.11ax, which provides a more stable connection in busy networks (for example, in offices or apartment buildings). However, for home use, it is sufficient Wi-Fi 5 (802.11ac).

4. Step-by-step Wi-Fi setup on the monitor

Connecting a monitor to Wi-Fi is easy, but the process may vary depending on the model. Let's look at some general instructions using popular brands as examples:
