To make a monitor wireless, you need to add a wireless display adapter or a wireless HDMI transmitter/receiver kit to its HDMI port. This eliminates the video cable between your computer and a non-smart monitor, allowing you to project your screen without a physical connection.
How to make a monitor wireless with a wireless display adapter
Microsoft's documented method for the Wireless Display Adapter is the most straightforward path for Windows users. This adapter is designed to work with an HDTV, monitor, or projector.
- Plug the adapter's HDMI end into the HDMI port on your monitor.
- Power on the adapter (typically via a USB cable that is part of the adapter).
- On your sending device, open the display or projection settings and select the adapter from the list of available wireless displays.
- Follow the pairing prompts that appear on your monitor and sending device.
This method directly addresses the challenge of setting up wireless connections by using a dedicated adapter that handles the wireless signal for a monitor that lacks built-in capabilities.
Using a wireless HDMI kit to make a monitor wireless
A wireless HDMI kit uses a transmitter and receiver pair to replace the HDMI cable. The wireless HDMI kit typically consists of a transmitter and a receiver. The transmitter is connected to your source device, such as a laptop, gaming console, or media player, while the receiver is connected to your monitor. Generally, you connect the transmitter to the source and the receiver to the monitor, power both on, and they establish a wireless link.
Using a wireless video transmitter and receiver
Wireless video transmitter and receiver kits are designed for longer-range wireless video transmission. Like HDMI kits, they consist of a transmitter (connected to the source) and a receiver (connected to the monitor).
Making a monitor wireless with Apple AirPlay
AirPlay allows you to mirror your iPhone or iPad screen to an AirPlay-compatible display. This only works if the monitor itself supports AirPlay, or if you connect an Apple TV or AirPlay-compatible smart TV to the monitor. The exact steps for an iPhone or iPad are documented by Apple.
- Connect your iPhone or iPad to the same Wi‑Fi network as the AirPlay-compatible TV or Mac.
- Open Control Center.
- On iPhone X or later, or iPad with iPadOS 13 or later, swipe down from the upper-right corner. On iPhone 8 or earlier, or iOS 11 or earlier, swipe up from the bottom edge.
- Tap Screen Mirroring.
- Select the TV or Mac from the list.
- If a passcode appears on the display, enter it on the iPhone or iPad.
This method is only for sending a signal from an Apple device to a display that already receives AirPlay. It does not make a standard non-smart monitor wireless without an external receiver.
What about Android and other devices?
Therefore, exact steps for casting from an Android device cannot be provided here. Android devices generally use Miracast or Google Cast, but the specific procedure depends on the device manufacturer and Android version.
Limitations of a wireless monitor setup
Wireless monitor connections have several inherent limitations. Signal interference from other wireless devices can degrade performance. Latency is typically higher than a wired HDMI connection, which can affect gaming or real-time applications. Range is limited, and performance drops with distance or obstacles. To optimize the performance, ensure that there is a clear line-of-sight between the transmitter and receiver and minimize interference from other devices. Most importantly, a non-smart monitor requires an external adapter, receiver, or transmitter to become wireless; there is no universal upgrade path without adding hardware.
Frequently Asked Questions
Can any monitor be made wireless?
Yes, most monitors can be made wireless with the right equipment. However, it's important to check if your specific monitor model is compatible with wireless adapters or if it has built-in connectivity options.
Can I use a wireless HDMI kit with any monitor?
Yes, as long as the monitor has an HDMI input. The kit's receiver plugs directly into that port, and the transmitter connects to your source device.
Will a wireless connection have the same picture quality as a wired HDMI cable?
Not always. Wireless connections can introduce compression or signal loss, especially over longer distances or with interference. High-end kits can approach wired quality, but a direct HDMI cable remains the most reliable for uncompressed video.
Does a wireless display adapter work with a laptop that doesn't have an HDMI port?
Yes, if the laptop supports wireless display projection (such as Miracast on Windows). The adapter itself connects to the monitor, and the laptop connects to the adapter over Wi-Fi Direct, not through its own HDMI port.
Can I use AirPlay to make a standard monitor wireless without an Apple TV?
No. AirPlay requires the receiving device to be an AirPlay-compatible smart TV, Apple TV, or Mac. A standard monitor without built-in AirPlay support cannot receive an AirPlay signal directly.
Are there any limitations or downsides to making a monitor wireless?
Yes, there are several limitations to consider. These include the potential for signal interference, especially if there are other wireless devices nearby. Additionally, wireless connections may introduce some latency, which can affect the responsiveness of the monitor. Finally, the range of the wireless connection may vary depending on the devices used, so it's important to consider the distance between the source device and the monitor.
