 Wireless Projectors: Seamless Connectivity Meets Superior Visuals

In the quest for the perfect home entertainment or professional presentation setup, wireless projectors are increasingly becoming the go-to choice. But what exactly does “wireless” entail? For many, it’s the allure of connecting devices without the hassle of cables.

Built-In Wireless Capabilities While it’s true that most projectors focus on delivering high-quality images, many modern projectors now come with built-in wireless features. These may include adapters that connect via USB or HDMI ports, transforming traditional projectors into smart, wireless devices.

Bluetooth and Wi-Fi: Understanding the Difference Bluetooth technology, commonly associated with wireless audio transmission, has limited bandwidth and is not suitable for video signals. It’s ideal for enhancing your projector’s audio experience, especially if the built-in speakers don’t meet your expectations. For a more permanent high-quality audio solution, consider pairing your projector with a soundbar.

Compatibility and Usage Choosing a wireless projector also means considering compatibility with operating systems like Android, Windows, or Apple. The intended use—be it streaming movies at home or conducting PowerPoint presentations in the office—will dictate the best wireless system for your needs.

Wireless Solutions for Home Entertainment As of 2020, the market has seen the introduction of reasonably priced wireless products that perform exceptionally well. Devices like the Google TV Chromecast, equipped with a new chipset, support 4K, Dolby Vision, and Bluetooth audio output. For Android users, options like Chromecast TV or Nvidia Shield TV provide seamless streaming of services like Netflix, YouTube, Disney+, and Kayo Sport. Apple ecosystem users can turn to Apple TV or Apple TV 4K for a comparable wireless experience.

Performance Variability Among Wireless Systems Not all wireless solutions are created equal. Performance benchmarks vary, with different devices sporting unique chipsets and RAM capacities. For instance, the Nvidia Shield TV’s Tegra X1+ chip outperforms the Chromecast TV’s ARM Cortex-A55 chipset, which in turn surpasses the Amazon TV stick’s ARM Cortex-A53 chipset in terms of performance.

By understanding the nuances of wireless projectors, consumers can make informed decisions that align with their specific needs, whether for a cozy movie night or a professional presentation.

Google Chromecast

Chromecast should be installed in the HDMI port of the projector.

The new Chromecast comes with a remote control. When turned on, you will see a home screen; simply browse through the Google Home Screen to choose which program you want to watch (works just like a TV).

The new Google TV Chromecast does have Bluetooth output for sound to connect to an external speaker.

Chromecast also allows you to mirror your phone or Windows desktop. On your Android phone, it’s called SmartView. Drag down from the top of the phone screen to bring up the menu. After you click the Smart View button, you should be able to see your phone mirrored on the big screen.

Windows 10 also has a similar function to Smart View, called ‘Connect’ or ‘Project’. Go to the bottom right corner of your Windows desktop and click the conversation icon. This lets you duplicate your screen, extend your existing screen to create more desktop space, or project to the second screen only.


USB Adapter

USB adapters are an early form of wireless technology for projectors. Each brand has its own wireless adapter and corresponding app. Some projectors include a USB adapter, while others require a separate purchase. Only the USB wireless adapter approved by a brand will work with that brand’s projector. This type of wireless connection only works if the projector is specifically stated to be wireless-capable or optionally wireless-capable.

Most brands require the installation of an app on Apple or Android devices. Some even offer desktop software for PCs and Macs



For example, BenQ and Optoma allow you to transmit photos, documents, and videos. Additionally, a projector screen can be split into four screens, enabling four users to use the same screen and share images simultaneously.

Besides this, if your handheld device has a camera, it can also be used as a document camera.


HDMI / MHL wireless adapter

An MHL wireless adapter is superior to a USB adapter. If your projector has an HDMI port that is MHL compatible, it will function more smoothly. Simply plug it into the HDMI/MHL port on your projector, and the MHL port will power the adapter without the need for additional power sources. To use it, download the app for the relevant adapter, and it will work in the same manner as the aforementioned USB adapter.

As the name suggests, you can also use it in the HDMI port of any non-MHL compatible projector; however, since it’s plugged into the HDMI port, additional power is required. (Please ask our friendly staff for more information.)

HDMI Wireless:

HDMI wireless has been available for many years, even before streaming became popular. It’s necessary if you wish to connect older devices wirelessly, such as Blu-ray or DVD players, or even your PC desktop. Additionally, it’s useful in situations where you prefer not to run a very long HDMI cable from the video source to the projector. For example, if the projector and the video source are 25 meters apart, instead of using a lengthy HDMI cable, you can opt for an HDMI wireless kit. An HDMI wireless kit consists of two parts: a transmitter and a receiver. The transmitter should be connected to the source, such as a Blu-ray player, DVD player, or AV receiver’s video output. The receiver should be connected to the projector, as it receives the video signal to display.

Some HDMI wireless kits require a direct line of sight to function flawlessly, while others can penetrate walls and transmit between different levels, like the BenQ WDP01 wireless kit or the Epson Full HD wireless kit



Miracast has been on the market for many years. It serves a similar purpose to Chromecast but is designed specifically for Windows and only allows you to mirror the screen of your device to the projector. What appears on your device will be exactly shown on the projector (mirroring). Certain projectors, for example, those from Panasonic, LG, and Epson, have built-in Miracast functionality. To make any projector with an HDMI input Miracast-capable, a separate Miracast adapter can be purchased, such as the Asus Miracast Dongle or the Microsoft wireless adapter



MHL technology enables you to mirror your device’s screen to the projector using a USB-C or MHL cable. This feature is available only on projectors and Android devices that support MHL functionality.
