Let‘s explore each of these options in more detail:
USB Connection
Connecting your Android or iPhone handset to your TV with a USB cable is one of the simplest ways to mirror your phone‘s screen or access media files and photos stored on it.
Nearly any smartphone can connect to a TV‘s USB port, provided the TV has a USB input. Most modern TV sets have USB ports, but older models may need an adapter like an HDMI to USB converter.
To wirelessly mirror your phone, you‘ll need to install an app on your device like AirScreen, LetsView, Easy Cast, etc. These apps send the phone‘s screen over the USB connection to be displayed on the TV. Make sure to enable USB debugging on Android.
Pros:
- Works for both iPhone and Android
- Allows access to stored media
- No internet required
Cons:
- Typically limited to a distance of 6 feet from TV
- Wireless mirroring may have lag
- Needs USB port on TV or adapter
HDMI Connection
HDMI is a digital audio/video cable standard found on most modern TVs. Connecting your smartphone to your TV‘s HDMI port offers high quality video and audio.
You‘ll need an adapter cable that converts your phone‘s output to HDMI. For iPhones, Apple‘s Lightning Digital AV dongle is an example. Android phones require USB-C to HDMI adapters.
Like with USB, wireless mirroring requires an app to send the phone‘s screen over HDMI to the TV. HDMI also provides access to media files on your phone.

- Also needs wireless mirroring app
Chromecast Built-in/Chromecast Device
Google‘s Chromecast technology offers easy wireless casting of content from phone to TV.
Many smart TVs today come with Chromecast built-in, allowing quick setup to cast from hundreds of compatible apps. For non-smart TVs, the Chromecast device plugs into an HDMI port.
Casting sends video streams from the cloud vs. mirroring your actual phone screen. This avoids lag while freeing up your phone.
Pros:
- Wireless, works at distance of router signal
- Casts natively from many apps
- High quality streams
- Phone freed up while casting
Cons:
- Requires compatible smart TV or Chromcast puck
- Doesn‘t mirror full phone screen
- Needs strong WiFi signal
Miracast Wireless Screen Mirroring
Miracast uses direct WiFi technology to wirelessly mirror your Android or Windows phone‘s screen to a compatible smart TV.
The TV creates a peer-to-peer connection with the phone over WiFi Direct to transmit the screen display, similar to Bluetooth pairing. This works independently of your home‘s WiFi.
Latency is usually lower than casting since it‘s a direct device-to-device connection. But quality can suffer if signal strength is weak between the phone and TV.
Pros:
- Convenient wireless mirroring
- Lower latency than casting
- Works independently of home WiFi
Cons:
- Lower quality than casting
- Both devices must support Miracast
- Distance limited by Miracast signal
Smartphone Hotspot
Using your phone as a portable WiFi hotspot allows you to provide internet access to a smart TV for its built-in apps.
Enable the mobile hotspot feature on your iPhone or Android device. Connect your smart TV to the phone‘s WiFi network just like you would to your home WiFi.
With the hotspot‘s internet access, your TV can run streaming apps, browsers, and other smart features. This works well for watching apps like Netflix.
Pros:
- Conveniently uses phone‘s data plan
- Works with any smart TV
- Allows TV‘s native apps to stream

Smartphone Hotspot + Streaming Device
You can also use your phone as a WiFi hotspot for streaming media devices like a Roku, Fire TV Stick, Apple TV, etc.
The streaming box connects to the hotspot just like the TV to access phone internet. The mobile hotspot‘s data powers streaming and casting through the device.
This enables any TV with an HDMI port to stream content using your phone‘s hotspot. It‘s also handy while traveling with a streaming stick.
Pros:
- Works on any TV with streaming device
- Convenient for on-the-go streaming
- Allows device‘s native apps
Cons:
- Phone may struggle with multiple streams
- Streaming box needs WiFi hotspot

Comparing Screen Mirroring vs. Casting
Two of the main ways your phone can send content to your TV wirelessly are screen mirroring and casting. What are the key differences?
Screen mirroring – This displays your actual phone screen directly on the TV. Miracast uses screen mirroring to send a feed of your mobile display to the TV in real-time.
Casting – This streams content from an app on your phone using WiFi, without mirroring the display. Chromecast enabled apps can cast videos from the cloud to your TV.
In most cases, casting provides a smoother, higher-quality streaming experience. But screen mirroring is more flexible since you can view anything on your phone.
Casting frees up your mobile device while streaming since processing happens on the TV device. With screen mirroring, your phone is working harder to render and transmit the screen.
Bottom line – if available, casting is best for streaming media like Netflix. For viewing personal videos or apps that don‘t support casting, screen mirroring may be preferable.
Troubleshooting Phone-to-TV Connections
Despite how easy the technology makes connecting your devices, you may occasionally run into issues getting your phone to successfully display on your TV. Here are some tips to troubleshoot:
-
Check compatibility – Ensure your phone, TV, cables and adapters support the connection method you are trying to use.
-
Update software – Upgrade to the latest firmware on your phone, TV and streaming devices for maximum compatibility.
-
Reboot devices – Toggle your phone and TV off and then back on to refresh the connection.
-
Check signal strength – If mirroring wirelessly, make sure your phone and TV have good WiFi/Miracast reception. Move them closer together or reduce interference.
-
Disable battery optimizations – On Android, turn off optimizations and power saving modes that may disrupt casting/mirroring apps.
-
Authorize apps – Make sure mirroring/casting apps have permission to access and display content from your phone.
-
Switch HDMI ports – Try connecting HDMI cables and adapters to different HDMI input ports on the TV.
How Much Data Do Streaming Services Use?
When using your smartphone‘s data plan to power TV streaming, it‘s important to keep track of how much data popular services like Netflix use.
According to Netflix, streaming uses:
- 1 GB per hour for Standard Definition
- 3 GB per hour for High Definition
- 7 GB per hour for Ultra HD/4K
Other sources like YouTube may use 0.7 GB per hour for 720p HD streaming. Live TV apps use 0.6 GB for an hour of streaming.
So for movies, you can estimate 2-3 GB per hour for HD. Streaming in 4K will use closer to 7 GB per hour with today‘s top quality.
Data Usage Tips for Phone Hotspots
Here are some tips to be mindful of your data usage when using a phone‘s cellular data plan as a hotspot for your TV:
-
Track usage – Use the hotspot settings or your carrier account to monitor data usage. Set alerts before your limit.
-
Lower quality – Stream in SD vs HD where possible, or change Netflix settings to "Data Saver" mode.
-
Update less – Disable auto-updates and background downloads which can eat up data fast.
-
Go offline – Downloading content to watch offline will avoid hogging your data plan.
-
Split streams – Multiple simultaneous streams will consume much more data, avoid when possible.
-
Limit social media – Videos and photos loading in apps and browser tabs can add up quicker than you think.
-
Find WiFi – Whenever home or around public hotspots, connect to WiFi to save your phone‘s limited data.
Recommended Data Plans for TV Streaming
Here are some recommended data allotments for comfortably powering TV streaming from your smartphone:
-
For SD streaming only: Minimum 10 GB per month
-
For HD streaming: 25-50 GB per month
-
For 4K UHD streaming: At least 100 GB per month
Of course it also depends how much you plan to stream. Binge watching will use much more than occasional viewing.
Most U.S. unlimited plans today offer over 50 GB before potential throttling, sufficient for HD. Truly unlimited options remove data worries but cost more.
Compare your carrier‘s data packages to pick a plan aligned with your TV streaming habits. And consider springing for unlimited if you‘ll be streaming hours daily.
Using Your Laptop as a Hotspot for Your TV
If your phone plan‘s data isn‘t enough for your streaming needs, another option is using a laptop as a hotspot for your TV instead.
Laptops can be easily configured as WiFi hotspots just like smartphones. Connect your TV to your laptop‘s hosted network.
Many laptops have Ethernet ports also, allowing you to wire them directly to your TV with an Ethernet cable if WiFi is sluggish.
Benefits over phone hotspots:
-
Typically no data limits to worry about
-
Faster hotspot speeds with laptops
-
Ethernet option for wired connection
-
Laptops have bigger batteries than phones
Just keep your laptop charged and nearby your TV, and enjoy unlimited high-speed streaming!
