How To Connect Laptop To Tv Wirelessly Windows 8

With Windows eight.1, nosotros are introducing wireless display developed on the Wi-Fi Alliance (WFA) Miracast wireless display specification, so y'all can now wirelessly project to a big screen without fussing with proprietary technologies, network access, and unlike display cables and adapters. Wireless brandish is available in new Windows eight.ane PCs – laptops, tablets, and all-in-ones — allowing you to display your full Windows 8.1 experience (up to 1080p) to large wireless display-enabled screens at abode and piece of work.

What can you lot do with information technology

Although it can be handy to turn your device into what is essentially a touch-screen remote command for watching online videos, we knew the potential was there to practice a lot more when you wirelessly project your Windows device to the large screen.

In Windows 8.1, wireless display is a great way to share annihilation you exercise on Windows with friends and family in the living room, with colleagues in the conference room, and with students in the classroom. Information technology lets you share experiences similar shopping on Amazon or eBay, checking out 360-degree panoramas of vacation destinations in Bing Travel , solving puzzles in Disney Fairies with the kids, enjoying photos from a form field trip on SkyDrive, or exploring the solar system with your classroom with the Earth Wide Telescope. Of grade, you lot can also use information technology for watching movies and videos through your favorite services like Netflix, Xbox Video and YouTube.

Wireless brandish puts Windows 8.1 on your big screen.

With wireless brandish in Windows eight.one, yous tin indistinguishable your principal display or extend your display, giving y'all two independent screens (multi-monitor). Duplicating the brandish takes what you have on the local screen of your device and shows it on the big screen. Extending your brandish allows you, for instance, to use Microsoft PowerPoint to show a presentation in Presenter View, where the local screen shows you your speaker notes, next slide, and slide controls, while the wireless display shows the audience your full-screen presentation. Bully for when y'all want to come from backside the podium, while keeping your notes and controls in the palm of your paw.

What y'all need

When you lot use wireless brandish, you have a source and a receiver: your Windows 8.one device is the source, while your Television receiver or projector is the receiver. If your brandish already has Miracast support, you are ready to go. If not, Miracast adapters provide an economic way to add wireless display to your existing TV or projector.

Wireless display works on new Windows 8.1 wireless PCs. This includes Surface ii and Surface Pro 2, Nokia Lumia 2520, and Intel Atom Generation three ("Bay Trail") and Intel Core Generation 4 ("Haswell") systems. Some PC manufacturers have likewise added wireless display to some of their systems that originally shipped with Windows 8. This includes the Surface Pro and many systems based on Intel Core Generation 3 ("Ivy Bridge") and Intel Wi-Fi. Be sure to check for updates from Windows Update and from your PC manufacturer, including driver updates listed as Optional, when determining whether your PC manufacturer has made wireless display available on your upgraded Windows 8 device.

As I mentioned earlier, we congenital wireless brandish on the Miracast industry-standard specification, which the industry based on widely adopted standards such as 802.11n, Wi-Fi Directly, and H.264/MPEG-iv AVC. We believe working with the industry and using manufacture standards allows broader adoption and interoperability by source devices (e.g., laptops, tablets and phones) and receivers (TVs, projectors, streaming players), and over fourth dimension allows the standard to accelerate beyond any one company's interests.

How to use it

We worked with several Miracast receivers during Windows 8.one evolution. Notable amongst these are the ActionTec ScreenBeam Pro and the Netgear Push2TV (PTV3000). These and other Miracast receivers work neat in bringing Windows viii.ane to the big screen. Additionally, ActionTec simplified firmware updating and configuration for their receiver by creating a Screenbeam Windows Store app using our new Wi-Fi Direct APIs (Windows.Devices.WiFiDirect). Whichever Miracast receiver y'all cull, be certain to update to the latest firmware for best results.

Note: ActionTec is providing readers of the Windows blog a 15% discount on the ActionTec Screenbeam Pro through their online store now through the finish of this year (12/31). Please utilise the Screenbeam Pro links in this blog mail service to receive the discount.

To get started with wireless display, first ensure that your Windows viii.ane device is set up past checking Windows Update and your PC manufacturer for whatever driver updates, including drivers presented equally optional. Subsequently your auto is prepare, you lot need to add together your wireless display receiver for the first time. To add it, open the Devices charm past swiping in from the right and then borer Devices (or if you're using a mouse, signal to the lower-correct corner of the screen, motion the mouse pointer up, and and so click Devices.). Select Project and then Add a wireless device to have Windows scan for available Miracast receivers.

Note: Wireless display is bachelor on most new Windows eight.ane PCs, but some PC manufacturers might choose not to include it on some new and upgraded PCs. Specifically, your PC needs WDDM 1.3 display and NDIS six.4 Wi-Fi drivers, enabled past the IHV and OEM for Miracast. If you don't meet "Add a wireless display" when you tap the Devices amuse and tap Projection, try going to Windows Update and downloading all available updates (including optional drivers). If yous still don't see it, check for boosted updates on your PC manufacturer'due south support site, or contact them to enquire how you can get this feature on your PC.

Selecting your receiver begins the secure pairing of your Windows 8.ane device to the Miracast receiver. Afterward pairing is finished, you'll exist able to project your full Windows 8.1 experience wirelessly onto your large screen. To extend projection, open up Devices and tap Projection once more (or press Windows fundamental + P), and then tap Extend.

To finish projection, open Devices and tap Projection once more (or printing Windows central + P), and and then tap or click Disconnect.

The next fourth dimension you lot use your wireless display it will be even simpler, as Windows remembers the displays you've used, and automatically shows them whenever they're bachelor. Simply open Devices, tap or click Project, and so tap or click the display you lot want.

The Project to a wireless brandish with Miracast commodity provides info about source and receiver setup, how to project to the receiver, and troubleshooting issues.

What do app developers demand to practice?

App developers do non demand to change their apps to have advantage of wireless brandish. By default, all apps will just piece of work with wireless display. We do however provide the ProjectionManager APIs, for developers who want to provide an enhanced feel with wireless display.

ProjectionManager APIs permit an app to detect a secondary monitor, and when the monitor is present, control what the app displays on the primary and secondary monitors. An case is a video or photo app, where the local screen shows the box shots, thumbnails, or playlist, while the wireless display shows the full-screen video or slide show. A game developer could provide controls for the game on the local device (due east.thou., cards in hand, steering wheel and cockpit controls) while the wireless display shows the action of the game on the big screen.

The ProjectionManager APIs are non specific to wireless display and work every bit well for wired monitors. In either case, wireless or wired, what gets displayed on either screen is up to the app developer.

How information technology works

For those interested in the nitty gritty of how wireless display works, here's a quick rundown. It begins with the discovery of available Miracast receivers, and then proceeds to establishing a point-to-point connectedness between the source and receiver over Wi-Fi Direct. Security is negotiated using Wi-Fi Protected Setup (WPS), with communication secured using WPA2-AES directly betwixt the Windows device and Miracast receiver. Once communication is established (two.4GHz by default or 5GHz if pre-connected to 5GHz AP), the source and receiver negotiate capabilities – e.one thousand., the resolution and refresh charge per unit (e.one thousand., 30Hz), content protection scheme, audio channels, etc. Once capabilities are agreed, Windows begins projecting its display and sound onto the remote device by encoding the local brandish and sound, and sending to the receiver, where the receiver decodes and displays. Anything your Windows PC has access to, you can wirelessly display on your big screen. This is, of form, but a loftier-level explanation of the steps involved, with the Wi-Fi Alliance Miracast site having more than details including the total specification.

In that location are other wireless display ("screen casting") alternatives, each having their ain advantages and drawbacks when compared to Miracast. Non all alternatives support full HD (1080p) and instead pinnacle-out at lower resolutions below what your Boob tube/projector may natively back up. Some of the alternatives piece of work well in home environments, but take difficulty in corporate and hotspot environments where the receiver has to authenticate onto the network using enterprise-grade security such as WPA2-Enterprise or hotspot style hallmark using a convict portal. Miracast is different, in that information technology is peer-to-peer, going directly between Windows and the receiver, and not over the Wi-Fi infrastructure network. This means that you can permit a guest (corporate or dwelling house) to projection in your conference or living room without you lot having to grant them network access (which could potentially give them access to other devices and content across what y'all might have intended). With wireless display, y'all're only granting them access to the display… not to your network.

Since the content comes from (or via) the Windows device, merely the Windows device needs Internet access, which can come up via its Wi-Fi, mobile broadband, or wired connection. Additionally, since we enabled wireless brandish in the Os and not tied to whatever detail application, whatever content in any app can take total advantage of the processing power of the PC, which enables a good wireless display experience across the range of Windows 8.1 devices and class-factors.

We are excited to have worked with our partners and the manufacture in bringing you a swell, no compromise, and standards-based, approach to wireless display. Nosotros wait forward to hearing nearly your experiences equally y'all projection your full Windows experience onto the large screen! Please let us know your thoughts by leaving usa a comment.
