Users often need to display photos or play videos on their TV when the router is unavailable, faulty, or simply out of range. For technology owners Haier This is a solvable problem that only requires the correct choice of hardware interface or direct connection technology.
In most cases, the lack of wireless internet isn't a critical obstacle to media streaming. Engineers have developed alternative data transfer protocols that operate via physical contact or by creating a local bridge between devices. You'll need to decide which method is most convenient: a wired connection with guaranteed image quality, or a wireless connection with limited functionality without internet access.
The main difficulty when working with Smart TV The problem with using a TV without internet access is that many apps require online authorization. However, system image display functions, such as screen mirroring or reading files from a USB, work offline. Below, we'll detail the steps for various TV usage scenarios.
Using a wired HDMI connection
The most stable and high-quality method of image transmission remains a physical cable connection. This method ensures high-definition video signal transmission without lag, which is critical for viewing dynamic content. You will need a special adapter, as modern smartphones do not have a full-fledged HDMI port.
For Android devices with a port Type-C an adapter is needed Type-C to HDMIIt is important that your phone supports the technology. MHL or Alt Mode, otherwise video transfer is impossible. iPhone owners will need an original adapter. Lightning to HDMI or USB-C to HDMI for new models, which is instantly recognized by the TV system.

Picture quality in this mode depends on the capabilities of the TV matrix and the cable version. Using certified cables allows you to achieve a resolution 4K at frequency 60 Hz, providing a clear and bright image. The wired method also allows you to charge your smartphone while watching, provided the adapter has an additional power port.
☑️ Checking HDMI connection readiness
Wi-Fi Direct and Screen Mirroring technology
Many users confuse the lack of internet access with the inability to use the Wi-Fi module. TVs Haier at the base Android TV They can create a direct connection to a phone without a router. This technology is called Wi-Fi Direct and allows you to transmit a video stream directly between devices.
To activate the function, go to the TV settings and find the section Net or Connections and turn it on Wi-Fi DirectThe device name and possibly a pairing password will appear on the screen.

It's worth noting that with this connection, the phone's internet connection may stop working, as the Wi-Fi module is busy transmitting video. However, local files, the gallery, and offline apps will function normally. Signal latency in this mode is minimal, but may be noticeable when gaming.
⚠️ Attention: The menu interface and item names may differ depending on the operating system version. Android and the TV manufacturer's shell. If you can't find the item you need, use the search in the settings.
Transferring media via USB drive
If wireless methods aren't an option and you don't have an HDMI cable handy, the most reliable option is a USB flash drive. This old-fashioned method is still effective for viewing movies and photo albums in high quality. You'll need a computer or laptop to pre-record the files onto the drive.

The advantage of this method is that it places no load on the phone's processor and eliminates lag. The TV reads data directly from the storage device, decoding the video stream internally. This is ideal for viewing large files. 4K, which can slow down during wireless transmission.
Setting up DLNA via a local network
Technology DLNA Allows you to stream content over a local network created by your phone. Even without internet access, if your router is turned on, or if your phone supports Wi-Fi and your TV connects to it as a client (although this is a rare scenario for TVs), streaming is possible. A more common scenario is creating a hotspot on the phone.
However, classic DLNA usually requires both devices to be on the same network. If you don't have a router, you can try creating a hotspot on your smartphone, but the TV must be able to connect to it as a regular Wi-Fi network (client mode). In the TV menu, select the network entered by your phone and connect.
Once connected, launch a DLNA-enabled media player app on your phone, such as VLC or the standard gallery. Find the broadcast icon and select your TV. HaierThe file will start playing on the big screen.

|---|---|---|---|
| Image quality | Maximum (Lossless) | Depends on the signal | Maximum |
| Do you need a router? | No | No | No |
| Lag | Absent | Minimum | Absent |
| Charging your phone | Yes (via adapter) | No (battery consumption) | No |
Using Chromecast Built-in
Many models Haier Smart TV equipped with a built-in function ChromecastWhile it's typically associated with the internet, a global network isn't always necessary for screen mirroring (Cast Screen) if the devices already "know" each other or are in line-of-sight mode.

Functionality may be limited compared to online mode. For example, you won't be able to launch YouTube via voice command, but you can still play a saved video from your gallery using a third-party player with casting support.
Troubleshooting and diagnostics
Technical difficulties may arise during the connection process. Often, the problem lies in incompatible file formats or outdated software. If the TV doesn't detect the phone, try restarting both devices—this clears temporary network errors.
When using an HDMI cable, make sure the correct signal source is selected. Some models Haier require manual activation of the HDMI port in the settings if it has been disabled to save power. Check the section Settings → System → Ports.
