		</div><p dir="ltr">The most reliable way to put your phone on a TV without Wi-Fi is a cable. A USB-C to HDMI adapter (or Apple&#8217;s AV adapter for older iPhones) needs no network at all. If you want wireless, Android phones can use Miracast or Wi-Fi Direct with a compatible TV, and iPhones can use peer-to-peer AirPlay with an Apple TV. Chromecast is the exception. It cannot cast without some kind of local network, though your phone&#8217;s hotspot can supply one.</p>
<p dir="ltr">&#8220;Without Wi-Fi&#8221; can mean three different things, and the right method depends on which one you need. This guide sorts the options into wired, direct wireless, and local-network-only, explains the limits of each, and covers the streaming-app restrictions that can block a connection even when everything is plugged in.</p>
<h2 dir="ltr">Three Meanings of &#8220;Without Wi-Fi&#8221;</h2>
<h3 dir="ltr"><strong>No Network at All</strong></h3>
<p dir="ltr">A wired connection between the phone and the TV. Nothing needs to be online.</p>
<h3 dir="ltr"><strong>No Router, but a Direct Wireless Link</strong></h3>
<p dir="ltr">The phone and TV connect straight to each other using Wi-Fi Direct, Miracast, or peer-to-peer AirPlay. There is no home network involved, though the radios still use Wi-Fi technology.</p>
<h3 dir="ltr"><strong>No Internet, but Still a Local Network</strong></h3>
<p dir="ltr">The phone creates a hotspot and the casting device joins it. There is a small network, but it does not need the internet.</p>
<h2 dir="ltr">Method 1: Wired HDMI Connection (Most Reliable)</h2>
<h3 dir="ltr"><strong>iPhone 15 and Later (USB-C)</strong></h3>
<p dir="ltr">9to5Mac reported in September 2023 that iPhone 15 models output video over DisplayPort. A USB 3.1 or faster cable is needed for high resolutions, and the cable in the box is USB 2. The report says the phone can drive up to 4K at 60Hz through a USB-C to HDMI adapter and confirmed that Apple&#8217;s USB-C Digital AV Multiport Adapter works. This is a secondary source quoting Apple.</p>
<h3 dir="ltr"><strong>iPhones With Lightning</strong></h3>
<p dir="ltr">Apple&#8217;s Lightning Digital AV Adapter mirrors the screen to an HDMI display at up to 1080p. You plug the adapter into the phone, connect an HDMI cable to the TV, and select that HDMI input.</p>
<h3 dir="ltr"><strong>Android Phones</strong></h3>
<p dir="ltr">A USB-C to HDMI connection works only if the phone&#8217;s USB-C port supports video output (known as DisplayPort Alt Mode). Whether a given phone supports it depends on its hardware, and the sources reviewed give no general rule, so check your phone&#8217;s spec sheet. Android Authority reported in March 2024 that Google had enabled DisplayPort Alt Mode for the Pixel 8 and Pixel 8 Pro in an Android 14 QPR3 beta, with a mirror display option, though the report noted it might be reverted. Do not assume the final status without checking.</p>
<h3 dir="ltr"><strong>What You Need</strong></h3>
<p dir="ltr">An adapter or cable rated for your phone and TV, an HDMI cable, and a free HDMI input on the TV. If the picture does not appear, check that the TV is set to the correct input and try a different cable.</p>
<h2 dir="ltr">Method 2: Miracast and Wi-Fi Direct on Android</h2>
<p dir="ltr">Many Android phones and smart TVs can connect directly over Miracast or Wi-Fi Direct, with no router. The terms vary by maker.</p>
<h3 dir="ltr"><strong>Samsung Phones and TVs</strong></h3>
<p dir="ltr">Samsung&#8217;s support page says the path on a Galaxy phone is to swipe down with two fingers to open the notification panel and choose Screen Mirroring, Quick Connect, or Smart View, then pick the TV. The TV must have screen mirroring turned on, and on some models the setting is under Menu, then Network, then Screen Mirroring. Samsung says mirroring works with Wi-Fi Direct TVs.</p>
<p dir="ltr">AirBeamTV, which sells a mirroring app, describes a Wi-Fi Direct method: on the TV, go to Settings, then Network, then Wi-Fi Direct; on the phone, go to Settings, then Wi-Fi, then Wi-Fi Direct, tap the TV, accept, and then start Smart View. The company itself says Wi-Fi Direct works but has limits. Treat these menu paths as a secondary source for Samsung models.</p>
<h3 dir="ltr"><strong>Other Brands</strong></h3>
<p dir="ltr">Other TV makers use names such as Screen Share, Cast, or Miracast. Google&#8217;s official position on Miracast was not verified for this article. Look in the TV&#8217;s network or input settings for a screen mirroring option and in the phone&#8217;s quick settings for Cast or Smart View.</p>
<h3 dir="ltr"><strong>Limits</strong></h3>
<p dir="ltr">Direct links can be less stable than a router-based connection, and they may reduce image quality. Some phones and TVs do not support Miracast at all, so it is worth checking the manual.</p>
<h2 dir="ltr">Method 3: Peer-to-Peer AirPlay for iPhone</h2>
<p dir="ltr">Apple&#8217;s deployment documentation on peer-to-peer AirPlay says that neither device requires an association with an existing infrastructure network. It needs an Apple TV HD (tvOS 9 or later) or an Apple TV 4K (tvOS 11 or later) and an iPhone, iPad, or Mac from late 2012 or newer. Discovery uses Bluetooth LE, and a temporary Wi-Fi channel carries the connection. Apple advises staying within about 25 to 30 feet.</p>
<p dir="ltr">The document is an IT deployment guide and not a consumer how-to, and it was published October 27, 2021. It requires Apple TV hardware. AirPlay-capable smart TVs are not covered, and current behavior in the newest tvOS was not verified. If you plan to depend on this, test it before you travel.</p>
<h2 dir="ltr">Method 4: Chromecast on a Phone Hotspot</h2>
<p dir="ltr">BGR reported on January 2, 2026 that a Chromecast does not need internet but does need a local Wi-Fi network. It can use a mobile hotspot, a travel router, or an Ethernet adapter with no internet connection, and the phone and Chromecast must be on the same network. BGR also says Guest Mode no longer works.</p>
<p dir="ltr">Google&#8217;s Chromecast setup page requires a secure Wi-Fi network and a phone that supports 5 GHz on Android 9 or later, and says both devices must be on the same network. It does not address hotspots or the lack of internet. Google TV Streamer was not covered in the sources reviewed.</p>
<p dir="ltr">A hotspot approach has an obvious wrinkle. The phone that is casting also has to provide the hotspot or join another one. Many phones cannot cast while hosting a hotspot, and the sources reviewed did not confirm either way, so test it first. A cheap travel router is the more dependable option.</p>
<h2 dir="ltr">Streaming Apps Can Block You</h2>
<p dir="ltr">A working connection does not guarantee that every app will show video. Netflix&#8217;s help center says AirPlay and screen mirroring are no longer supported by Netflix on iPhone, iPad, and Mac. On Android, apps that mirror to a TV might not be supported. For USB-C connections, the cable or adapter must support HDCP 2.2. For Lightning, Netflix tells users to check Settings, then General, then About, then Apple HDMI Adapter, and says models A1438 and A1621 are supported.</p>
<p dir="ltr">That contradicts the common assumption that a cable always works. If you see a black screen with sound, copy protection is the likely cause. Try a different adapter, a different app, or play downloaded content in the app on the TV itself. Other services may apply similar rules, though this article reviewed only Netflix&#8217;s.</p>
<h2 dir="ltr">Which Method Should You Use?</h2>
<h3 dir="ltr"><strong>Hotel Room or Trip With No Reliable Network</strong></h3>
<p dir="ltr">Use a wired HDMI adapter. It needs nothing but the TV&#8217;s HDMI port.</p>
<h3 dir="ltr"><strong>Meeting Room or Classroom With a Compatible Smart TV</strong></h3>
<p dir="ltr">Try Miracast, Smart View, or peer-to-peer AirPlay with an Apple TV. Test it before the event.</p>
<h3 dir="ltr"><strong>Home Setup With a Chromecast and a Dead Router</strong></h3>
<p dir="ltr">Use a travel router or a second phone&#8217;s hotspot to give the Chromecast a network.</p>
<h3 dir="ltr"><strong>Showing Video From a Subscription App</strong></h3>
<p dir="ltr">Check the app&#8217;s rules. For Netflix, use the app on the TV or a supported adapter instead of mirroring.</p>
<h2 dir="ltr">Troubleshooting</h2>
<p dir="ltr">If the TV does not show the phone, confirm the right input and that screen mirroring is turned on at the TV. If the picture stutters on a wireless link, move closer, remove obstacles, or switch to a cable. If a cable gives no picture on an Android phone, the phone may not support video output over USB-C. If you see a black screen with audio only, suspect HDCP or app restrictions. Restart both devices and try again before changing anything else.</p>
<h2 dir="ltr">A Quick Test Before You Travel</h2>
<p dir="ltr">Casting problems usually show up at the worst moment, in a hotel room or a meeting. If you plan to rely on a method, test it at home with the Wi-Fi switched off. For a wired setup, plug the adapter into the phone and a TV, and confirm the picture and sound. For Miracast or Smart View, confirm that the TV&#8217;s screen mirroring setting is on. For peer-to-peer AirPlay, test with the actual Apple TV you will use. For a hotspot setup, confirm that the casting device can join the network and that your phone can reach it. Write down what worked so you can repeat it quickly.</p>
<h2 dir="ltr">What to Pack</h2>
<p dir="ltr">For the wired route, bring the right adapter for your phone, a spare HDMI cable, and, if you have an iPhone 15 or later, a USB cable rated for high resolution, since 9to5Mac reported that the cable in the box is USB 2. For a Chromecast, a small travel router is the most dependable way to create a local network. Keep a charger handy, because mirroring tends to drain the battery quickly, though the sources reviewed do not quantify that.</p>
<h2 dir="ltr">Choosing by Phone and TV Combination</h2>
<p dir="ltr">If you have an iPhone and an Apple TV, peer-to-peer AirPlay is the wireless route worth testing. If you have a Galaxy phone and a Samsung TV, Smart View with Wi-Fi Direct is the documented route. If you have a different Android phone and a smart TV, check both devices for Miracast-style options, and fall back to a wired adapter if neither shows one. If you have a Chromecast and no router, add a travel router or a hotspot. Match the method to the equipment you already own before buying anything.</p>
<h2 dir="ltr">Frequently Asked Questions</h2>
<h3 dir="ltr">Can I cast my phone to a TV with no Wi-Fi at all?</h3>
<p dir="ltr">Yes, with a wired HDMI connection, or wirelessly with Miracast or Wi-Fi Direct on compatible Android phones and TVs, or peer-to-peer AirPlay with an Apple TV.</p>
<h3 dir="ltr">Does Chromecast work without Wi-Fi?</h3>
<p dir="ltr">Not with no network at all. BGR says it needs a local Wi-Fi network, which can come from a hotspot or travel router, but not necessarily the internet.</p>
<h3 dir="ltr">Does my Android phone support HDMI output?</h3>
<p dir="ltr">It depends on the hardware. The sources reviewed give no general rule, so check your phone&#8217;s specifications for video output over USB-C.</p>
<h3 dir="ltr">Why does Netflix show a black screen when I mirror?</h3>
<p dir="ltr">Netflix says mirroring is not supported on iPhone, iPad, and Mac, and that USB-C adapters must support HDCP 2.2. Lightning adapters A1438 and A1621 are listed as supported.</p>
<h3 dir="ltr">Is a cable better than wireless casting?</h3>
<p dir="ltr">A cable removes network problems and is the most reliable choice, though app restrictions can still apply.</p>
