Ya sea que esté dirigiendo una llamada de ventas, una sesión de capacitación o desee una presentación innovadora para los primeros puestos, ¿por qué no sorprenderlos conectando de forma inalámbrica su computadora portátil, tableta o teléfono al proyector oa la pantalla grande de la sala? Con el equipo adecuado, es más fácil de lo que piensa.
What is it? Has anyone from your company come to the office in the last 10 months due to a global pandemic? The good news is that some of the same inexpensive devices that stream entertainment media over a home Wi-Fi network—Chromecast, Apple TV, Roku, and others—can also be used in the conference room. You can practice now while working from home, and then be ready to go when the vaccines have finished rolling out, the pandemic recedes, and offices reopen. These 11 devices connect to a projector, large monitor or TV to mirror the screen of a laptop, tablet or smartphone so you can present from your own device from anywhere in the room. Some use an HDMI cable to connect to the display or projector, while others look like a large USB stick that plugs directly into the display's HDMI port. Even the tallest can travel with you or be permanently (and quietly) ensconced on a screen in a conference room, or even a TV in the den for the work-at-home crowd. Then all you have to do is enter, press your device or a few keys, and you're on the big screen. (See some typical installation instructions.) All mirroring devices in this roundup support HD resolution of at least 1920 x 1080 pixels, the standard for professional graphics, and some of the newer ones listed here can handle 4K resolution up to 3820 x 2160 pixels, displaying four times the detail. . . To many this will seem like overkill, but it's perfect for a business reviewing architectural renderings of a new factory, previewing a UHD ad, or upscaling a high-resolution image. The bad news: Most of these devices are not suitable for all work situations. Consider:
- Apple TV 4K connects to MacBooks, iPads, and iPhones, but not Windows, Chrome OS, or Android products.
- Miracast devices, such as Microsoft's 4K Wireless Display Adapter, work with Windows systems, as well as Android tablets and phones, but not with Apple products or Chromebooks.
- Chromecast can mirror Android screens directly, but it relies on Chromecast apps rather than true mirroring for other types of devices.
That said, some newer devices reflect a broader range of systems. If you really want to support all kinds of laptops and mobile devices, you should consider getting a device with wider compatibility. Otherwise, choose the one that best suits your needs based on what the people in your office are wearing. After all, with so many options, there has never been a better time to introduce wireless technology.
Apple TV 4K / Apple TV HD
Based on Apple's AirPlay 2 technology, Apple TV 4K wirelessly mirrors footage to a Mac, iPhone, or iPad in crisp 3840 x 2160 resolution. Unfortunately, you have to stay in the Apple ecosystem. To use it, forget about Android, Chromebooks, and Windows devices.

Apple They may look the same, but the Apple TV 4K (left) supports an ultra-sharp 3840 x 2160 resolution, while the Apple TV HD (right) tops out at 1920 x 1080 pixels. (Click on any image in this story to enlarge it.) With hardware similar to an iPad, the Apple TV 4K has an A10X Fusion processor and 32GB ($179) or 64GB ($199) of storage for presentations, videos, and the occasional movie or game. It uses the 2,4 GHz and 5 GHz Wi-Fi bands or a wired Ethernet LAN, has an HDMI port, and runs on an AC cord. Apple TV can be controlled from across the room with its Siri Remote, which listens for commands. At 3.9 x 3.9 x 1.4 inches, the Apple TV 4K is probably too big for the back of a TV, but third parties like Innovelis make wall-mount brackets. If the price of the Apple TV 4K is out of your reach, or you don't have a display or projector that supports 4K, the company's $149 Apple TV HD is a step up with a 1920 x 1080 resolution, an older A8 processor,
Google Chromecast / Google Chromecast with Google TV
Instead of mirroring the screens of all computing platforms, the XNUMXrd generation Chromecast and the newer Chromecast with Google TV take a different approach. They allow Android phones and tablets to share their screens wirelessly, but Windows PCs, Macs, Chromebooks, iPhones and iPads must use one of the thousands of Chromecast apps available to "cast" to the big screen. The range of supported Chromecast apps includes the ubiquitous Chrome browser, YouTube, and Google Slides, but ignores corporate mainstays like PowerPoint and Keynote.
![google chromecast espejo de pantalla inalámbrico de tercera generación google tv]()
Google Chromecast (left) and Chromecast with Google TV (right) mirror Android devices and "cast" from other platforms through Chromecast apps. Both Chromecast devices are small and have flat HDMI cables to connect them to a display and take advantage of the 2,4 and 5 GHz bands of a Wi-Fi network. The USB port on a newer display or TV should be able to power either device, but each includes an AC adapter, just in case. The two Chromecast devices diverge in terms of resolution, with the Chromecast producing 1920 x 1080 pixels and the Chromecast with Google TV displaying the crisp 3840 x 2160 pixel resolution. Instead of the basic black Chromecast device, the Chromecast with Google TV is available in white (aka Snow), light blue (Sky), or salmon (Sunrise) and includes a voice-activated remote. The Chromecast HD retails for $30, while the Chromecast UHD with Google TV is $50, making them screen-sharing bargains.
IOGear Wireless Mobile and PC to HDTV Screen Sharing Receiver (GWAVRC)
IOGear's PC to HDTV Wireless Mobile Screen Sharing Receiver is a mouthful, but by using a proprietary high-power chipset and high-gain antenna design, it offers the benefit of being able to stay connected up to 50 feet of distance, according to the company. . Better known as the GWAVRC, the IOGear receiver is for those with large rooms to fill with wireless video and presentations.

IOGear's IOGear GWAVRC can stream content from Android and Windows devices up to 15 meters away. Based on Miracast technology, the GWAVRC can share the screens of Windows PCs as well as Android phones and tablets over a Wi-Fi network using the 2,4GHz or 5GHz band. It cannot connect to Chromebooks, Mac, iPhones or iPads and reaches a resolution of 1920 x 1080. At 3.4 x 2.6 x 0.6 inches, the GWAVRC device can be placed next to or behind the TV or display. It comes with a USB power adapter, but newer TVs and displays should be able to provide enough power for operation. With the ability to send signals in more space, the IOGear GWAVRC could be the champion of long distance mirroring for your desktop.
Microsoft 4K Wireless Display Adapter
Microsoft's third-generation 4K wireless display adapter picks up where the company's old mirroring devices left off, allowing 4K resolution screen sharing in a small package.
![espejo de pantalla inalámbrico microsoft 4k wda]()
Microsoft The Microsoft Wireless 4K Display Adapter can be powered from a display via its USB socket. Fortunately, it retains the unique design of its predecessor, featuring a 21-inch cable with an HDMI connector on one end and a USB connector on the other. In the middle is a small electronics box. This design allows you to connect both ends to the back of a TV or display, so that the display receives both a signal through the HDMI connector and power through the USB connector. The device does not include an AC adapter for displays without a USB port. Officially, it can mirror a variety of Microsoft Surface devices, but it should work with almost any recent Miracast-enabled system, like Windows 10 PCs or Android phones and tablets. However, it ignores Apple devices and Chromebooks. Capable of wireless mirroring with resolutions up to 3840 x 2160, the 4K Wireless Display Adapter uses 2,4GHz and 5GHz Wi-Fi bands. Easy to set up, the device lets you quickly bring a 4K video or presentation to the front of your to your colleagues with no wires in sight. The device costs $60, but we've seen it for around $20 less at online retailers.
