To put PC content on an HDTV without a video cable, choose a method that matches what you want to show: use Miracast to project a Windows display, Google Cast to send a Chrome tab or screen, or DLNA to play stored media files on a compatible TV. The TV or streaming receiver must support the method you choose.
Choose the right wireless method
These options do different jobs. Miracast and Chrome screen casting can show your computer display; DLNA is for browsing or playing media files, not duplicating the desktop.
| Method | Best for | What you need to check |
|---|---|---|
| Miracast | Projecting or mirroring a Windows display | Both the PC and TV or receiver must support Miracast. If the TV does not, a compatible HDMI Miracast adapter may work. Microsoft’s wireless-display instructions explain the connection flow. |
| Chrome / Google Cast | Casting a Chrome tab or the computer screen | Use an updated Chrome browser and a compatible Chromecast, Google TV Streamer (4K), or TV with Google Cast. Google calls for a strong connection to the same Wi-Fi network. Google’s Chrome casting guide covers the options. |
| DLNA | Playing individual stored media files | The TV and the media software must support DLNA. DLNA is not a general desktop-mirroring method. Check your specific TV and software documentation. HP’s overview of connecting a laptop to a TV describes DLNA as a home-network media option. |
| AirPlay | Wireless media or display use from a Mac | The Mac and TV or receiver must support AirPlay. Confirm compatibility for your specific devices and follow Apple’s current instructions. HP’s overview identifies AirPlay as a Mac option. |
Project a Windows PC with Miracast
Start here if you want your Windows display on the TV. Miracast works only when both the computer and receiving display support it; Windows key + K is a way to find and connect to a supported display, not a way to add Miracast support to incompatible hardware.
- Turn on the TV or wireless display and make sure its Miracast or wireless-display feature is enabled. Select the appropriate TV input if needed.
- On the PC, press Windows key + K to open the Cast panel.
- Select the TV or receiver from the list of available displays and follow any on-screen prompts.
If the TV has no Miracast receiver, Microsoft says you can connect a Miracast adapter to the TV’s HDMI port. Check the adapter’s requirements before buying: Microsoft’s adapter guidance says it works best when the HDTV has both HDMI and USB charging ports. See Microsoft’s Wireless Display Adapter guidance.

Cast a Chrome tab or screen with Google Cast
Choose this route if your receiver is a Chromecast, Google TV Streamer (4K), or a TV with Google Cast. Google requires an updated Chrome browser and a strong connection to the same Wi-Fi network for the computer and receiver.
- Open Chrome on the PC and connect the computer and receiver to the same Wi-Fi network.
- Open Chrome’s Cast menu and choose the compatible TV or receiver.
- Choose whether to cast a browser tab or the computer screen, then follow Chrome’s prompts.
Audio behavior can differ by choice: Google notes that audio may remain on the computer when you cast the whole screen, while casting a Chrome tab can send audio to the TV. If TV audio matters, try tab casting. Google explains tab and screen casting here.

Play PC media files with DLNA
DLNA is worth checking when you want to play stored photos, music, or videos on the TV rather than see the entire PC desktop. The TV and the media-serving software must both support DLNA, and availability varies by device and software. Consult their documentation to confirm support and setup; the general label “smart TV” alone does not establish DLNA compatibility.
Troubleshoot a missing display or failed connection
First check compatibility, then connectivity. Microsoft’s guidance for wireless display problems recommends checking Miracast support on both devices, making sure Wi-Fi is on, verifying that the display’s Miracast function is enabled, updating drivers and firmware, and restarting or reconnecting the devices. Microsoft’s wireless-display troubleshooting page provides further steps.

- The TV appears but will not connect: Restart the PC and receiver, then try removing and reconnecting the display. Recheck manufacturer-specific setup requirements.
- Chrome does not find the receiver: Confirm that the receiver supports Google Cast, Chrome is updated, and both devices have a strong connection to the same Wi-Fi network.
- You hear sound on the PC instead of the TV: If you are casting the whole screen in Chrome, try casting the tab instead; Google documents that whole-screen audio may play on the computer.
- You can see the desktop but cannot browse files from the TV: Miracast or screen casting is not the same as DLNA file sharing. Check whether the TV and media software support DLNA.
Windows 10 support status
Windows 10 support ended on October 14, 2025, according to Microsoft’s support notice. A Windows 10 PC may still operate, but it is no longer a supported operating system; do not treat it as equivalent to a currently supported Windows release for ongoing support and security.
