Many owners of modern electronics often face a situation where they need to quickly transfer photos or videos from their smartphone to a large screen wirelessly. TVs from the brand Dexp, as with most Android TV devices, this feature is powered by technology Wi-Fi DirectHowever, users often wonder where exactly this option is hidden in the menu, as it is not always displayed on the home screen or immediately visible after activation.
Finding the right section can take time, especially if the system interface has been updated or the TV model has a specific firmware version. It's important to understand that Wi-Fi Direct This isn't just a regular router connection, but rather the creation of a direct access point between your gadget and TV. That's why the settings for this feature are often hidden in deep submenus or require certain conditions to be met.
In this article, we'll take a detailed look at the algorithm for finding and setting up a direct connection. You'll learn how to avoid common errors, why the feature may be inactive, and what alternative content streaming methods your operating system offers. DexpOnce you understand the menu structure, you can easily manage the connection of any mobile device.
Features of Wi-Fi Direct implementation in Dexp TVs
Televisions Dexp often work on the basis of an operating system Android TV or its modifications, which determines the logic behind the network settings. Unlike proprietary systems from other brands, wireless interface management is centralized. Wi-Fi Direct In this ecosystem, it often runs in the background or activates automatically when attempting to connect from an external device, which can be confusing for a user looking for an obvious power button.
Technically, the TV's wireless module must support both client mode (connecting to a home router) and access point mode (for Direct). Not all models Dexp have this kind of hardware power. In budget series, activating a direct connection can interrupt the connection to the main internet unless a dual-band router or a separate module is used.
Another important feature is version dependency. firmwareManufacturers regularly update software, changing the location of menu items or renaming them. What was called "Wi-Fi Direct" on one model may be hidden under the name "Screen Mirroring" or "Wireless Display" on another. Therefore, if you don't find the option right away, it's worth checking the latest software version in the system settings.
Why can a function be named differently?
Terminology may vary across Android TV versions and manufacturer skins. Wi-Fi Direct is a core technology, but the user interface may refer to it as "Screen Casting," "Miracast," "Wireless Display," or simply hide it in the device connection menu. This depends on the brand's marketing strategy and the operating system version.
Step-by-step search for a function in the settings menu
To find the desired option, you need to navigate through the system menu. The interface may vary slightly depending on the model year, but the general structure remains consistent across the Android platform. First, press the "Menu" or "Settings" button on the remote control, usually marked with a gear or three dots.
The further algorithm of actions looks like this:
- 📺 Go to the section

If you don't see any explicit mention in the network section Wi-Fi Direct, try accessing the advanced Wi-Fi settings. Sometimes the switch is there, but it's grayed out until the TV detects a connection attempt from the smartphone. You should also check the "Connected Devices" section, which may contain a menu for adding new devices.
☑️ Check before connection
It is important to note that in some models Dexp Activating this feature requires disconnecting the primary Wi-Fi connection to the router if the module operates in the same frequency band. The system may prompt you to switch, but this is normal device behavior. Once activated, the TV will begin searching for available devices or become visible to them.
Alternative connection and broadcast methods

This allows you to stream videos and photos without having to navigate complex settings. Wi-Fi DirectUsing specialized applications often results in lower latency and better image quality.
⚠️ Important: When using screen sharing (Miracast/AirPlay) over Wi-Fi Direct or a shared network, ensure your router supports the 802.11ac (5 GHz) standard. Otherwise, stuttering and audio desync may occur when streaming high-resolution video.
Troubleshooting device detection issues
One of the most common problems is the situation when the TV Dexp The TV isn't visible in the list of available devices on your smartphone, even though the feature appears to be enabled. This could be due to security or power saving settings. First, check that your TV isn't in Airplane mode or that Wi-Fi isn't disabled completely.

|---|---|---|---|
| Do you need a router? | No | Yes | No |
| Transfer speed | High | Very high | Low |
| Range of action | Up to 10 meters | Depends on the router | Up to 5 meters |
| 4K video transmission | Not recommended | Supported | Impossible |
