Mobile gaming has long ceased to be the domain of simple casual games that drag you in a queue for a couple of minutes. Modern smartphones have computing power capable of running console-level projects, but even the largest screen diagonal flagship does not provide complete immersion. It is at this moment that a natural desire arises to display the picture on a large TV screen in order to enjoy the detailed textures and atmosphere of what is happening.
Fortunately, the ecosystem Android provides users with many tools to implement this task, from standard wireless transmission functions to specialized hardware solutions. The choice of a specific method directly depends on the model of your TV, the version of the phone's operating system and the requirements for signal delay (input lag). In this article we will analyze in detail all the available methods, their advantages and hidden disadvantages.
Some methods will require a stable Wi-Fi network, others will require the purchase of additional equipment such as an HDMI cable or set-top box. It is important to understand that for dynamic shooters or racing games, the minimum delay between pressing a button on the gamepad and the action on the screen is critical, while for turn-based strategies this parameter is less important.
Wireless broadcasting through built-in Android functions
The most obvious and accessible way is to use wireless screen mirroring protocols, which are built into most modern TVs and smartphones. In the Android ecosystem, this function can be called differently depending on the manufacturer: Samsung, Xiaomi, or simply “Broadcast” in pure Android. To activate this option, you usually do not need to install third-party software. Just make sure that both devices - smartphone and TV - are connected to the same Wi-Fi network. Then you need to find the corresponding icon in the notification shade of your phone and select your TV from the list of available devices. After pairing, the image from the mobile display will instantly appear on the big screen. Miracast, Smart View from Samsung, Transmit from Xiaomi or simply “Broadcast” in pure Android.
To activate this option, you usually do not need to install third-party software. Just make sure that both devices - smartphone and TV - are connected to the same Wi-Fi network. Then you need to find the corresponding icon in the notification shade of your phone and select your TV from the list of available devices. Once paired, the image from your mobile display will instantly appear on the big screen.
However, it is worth considering that with this method, complete duplication of the screen occurs. This means that all notifications, incoming calls and system messages will be visible to viewers unless you enable Do Not Disturb mode. In addition, the game interface will be scaled to the resolution of the TV, which sometimes leads to the appearance of black bars at the edges of the image if the_aspect ratio_ of the devices does not match.
⚠️ Attention: When using wireless broadcasting for games, it is critical to have a router that supports the 5 GHz frequency. On the overloaded 2.4 GHz frequency, input lag can reach 200-300 ms, which will make completing dynamic levels almost impossible.
☑️ Preparing for wireless broadcast
Google Chromecast technology for games
Unlike simple screen mirroring, the technology Chromecast (or the built-in Cast function in Android) works on a different principle. It allows you to transmit a video stream directly from the application, optimizing it for the TV, which often gives a more stable picture and less load on the smartphone battery.
Many modern games and streaming services have built-in Cast support. The broadcast icon is usually located in the corner of the game menu or in the application header. When you press it, the phone acts as a control panel, and the video stream is processed on the side of the TV or the dongle adapter connected to it.
This method is especially effective if you do not have a Smart TV with Miracast support, but have an adapter Google Chromecast. It provides a smoother picture due to hardware decoding on the receiver side. However, not all games support this feature natively, which limits its applicability only to certain titles.
For advanced users, it is possible to force a broadcast through the Chrome browser on a computer to which the Chromecast is connected, but this adds an extra link in the chain and increases the latency. Live broadcast from your phone is always preferable for interactive content.
If the game does not see the Cast button, try starting the system screen broadcast, and only then opening the game. This will force the TV to accept any video signal from the phone, even if the application does not directly support Chromecast.
Using an HDMI cable and USB-C adapters
When wireless methods do not provide adequate performance or stability, the “good old” physical connection comes to the rescue. Connecting your smartphone to your TV via an HDMI cable guarantees the lowest possible latency and maximum image quality without compression artifacts.
To implement this method, you will need a USB-C to HDMI adapter. It is important to check whether your specific smartphone supports video output through the charging port. The function, known as MHL (Mobile High-Definition Link) or DisplayPort Alt Mode, is not available on all budget models, although flagships from Samsung, Sony and Huawei are usually equipped with it.
The connection process is simple: one end of the adapter is inserted into the phone connector, and the other is connected to a regular HDMI cable going to TV. The smartphone will automatically detect the external device and switch the video output. In some cases, for example, Samsung devices with the function DeX, the phone interface is transformed into a full-fledged desktop, convenient for controlling a mouse or gamepad.
| Connection type | Input Lag | Picture quality | Battery consumption |
|---|---|---|---|
| Wi-Fi (2.4 GHz) | High (150+ ms) | Medium (compression) | Low |
| Wi-Fi (5 GHz) | Average (50-80 ms) | Good | Average |
| HDMI cable | Minimum (< 20 ms) | Excellent (uncompressed) | High (requires power) |
⚠️ Attention: When connected via HDMI, the phone may drain quickly as the video output consumes a lot of power. It is recommended to use an adapter with an additional charging port (USB-C PD) to connect the power supply at the same time as transmitting video.
Streaming games through cloud services and PC
If the power of your smartphone is not enough to run a heavy game on high settings, or you want to play projects that are only available on PC/consoles, remote streaming technologies come to the rescue. Services like GeForce Now, Xbox Cloud Gaming or Steam Link allow you to broadcast gameplay directly to your TV.
In the case of Steam Link or applications from consoles (PS Remote Play, Xbox App), your powerful computer or set-top box processes graphics, and the smartphone acts only as a receiver of the video stream and a transmitter of control commands. This takes the load off the phone's processor and prevents it from overheating during long sessions.
To set up such a connection, you need to install the appropriate application on your smartphone and on the host device (PC or console). Both devices must be on the same local network, preferably with a gigabit cable connection for the host and 5 GHz Wi-Fi for the phone. This will provide a smooth picture in 1080p or even 4K resolution.
Cloud gaming works differently: the game runs on the provider’s remote servers. You only need stable Internet with high upload speed and low ping. Cloud service applications often have built-in Cast support, which allows you to display the picture directly on the TV, bypassing the smartphone screen.
Why can the picture be scattered into squares?
If you see artifacts in the form of squares or blur when changing frames quickly, this is a sign of insufficient channel bandwidth. Try reducing the stream quality in the application settings from 1080p to 720p or moving closer to the router.
Specialized applications for gamepads and controls
Broadcasting the image is only half the battle. To play comfortably on a large screen, touch controls become inconvenient, since your fingers block part of the view and there is no tactile feedback. The solution is to connect a physical gamepad to a smartphone.
Modern controllers from Xbox, PlayStation (DualShock 4 / DualSense) and third-party manufacturers (8BitDo, GameSir) easily pair with Android via Bluetooth. Once connected, the TV will display the picture, and you will be able to control the character by holding the gamepad in your hands, without touching the phone screen.
Some applications, such as GameSir World or settings in GeForce Now, allow you to reassign buttons for games that do not have native controller support. This turns any game into a full console experience. It is important to check the key layout, as in some emulators it may differ from the standard one.
If you are using an HDMI connection, some smartphones allow you to connect the gamepad directly to the phone's USB port via an OTG cable, which eliminates Bluetooth connection delays. This is an ideal option for rhythm games and fighting games, where every millisecond of reaction is important.
The ideal combination for mobile gaming on TV: Smartphone with HDMI output + Adapter with charging + Wired gamepad + HDMI cable. This gives a latency comparable to native consoles.
Solving problems with latency and image quality
Even with the correct settings, users may experience out-of-sync audio and video or a “floating” picture. Often the problem lies in the settings of the TV itself. Many modern panels use image post-processing (motion smoothing, color enhancement), which introduces additional delay.
To minimize this effect, you need to switch the TV to “Game Mode”. In this mode, unnecessary video signal processing algorithms are disabled, which significantly reduces input lag. You can find this setting in the picture menu of your TV, usually it is called Picture Mode → Game.
You should also pay attention to the output resolution. If your router can't handle 4K streams, forcing the quality down to 1080p in your phone or streaming app settings will make the picture smoother. Stable 60 frames per second in FullHD is better than slow 30 frames in 4K.
In rare cases, the problem may be with the firmware version of the TV or smartphone. Manufacturers regularly release updates that optimize data transfer protocols. Check for software updates in the section Settings → About phone → System update and a similar menu on the TV.
⚠️ Attention: The interfaces of TVs of different brands (LG webOS, Samsung Tizen, Android TV) are constantly updated. The location of Game Mode menu items or network settings may vary. If you do not find the described settings, check the official instructions for your TV model.
Frequently asked questions (FAQ)
Is it possible to broadcast the sound of the game separately to speakers and not to the TV?
Yes, this is possible, but it depends on the Android version and the specific application. In standard Bluetooth settings, you can select the audio output device separately from the video, but when mirroring the screen, the sound most often runs synchronously with the video stream on the TV. To separate audio, third-party mixer applications or settings in the streaming service itself are sometimes required.
Why does the game slow down a lot when broadcasting via Wi-Fi?
The main reason is an unstable signal or low channel bandwidth. Make sure you are using a 5 GHz network and not a 2.4 GHz one. Also try moving away other devices that create interference (microwaves, baby monitors) and bringing the phone closer to the router. Closing background apps on your phone will also help free up resources.
Does my budget smartphone support video output via HDMI?
Unfortunately, most budget smartphones do not have hardware support for video output via USB-C (DisplayPort Alt Mode). In such cases, the port is used only for charging and data transfer. You can check this on the manufacturer’s official website in the characteristics section or by trying to connect a cheap USB-C to HDMI adapter - if there is no signal, then the function is not supported.
How to play games from a PC on a TV without a set-top box?
Use the Steam Link or Moonlight application (for NVIDIA video cards). Install the app on your smartphone, connect your phone to your TV via HDMI, or cast your phone screen to TV via Wi-Fi. Launch the game on your PC, and it will be displayed on the big screen, controlled from a gamepad connected to the phone.
Does broadcasting wear out your phone's battery?
Yes, broadcasting, especially over Wi-Fi and with the smartphone screen on, is an energy-intensive process. The processor and wireless module work under high load, which leads to heating and rapid discharge. It is recommended to keep your phone charged during long gaming sessions using an adapter with Pass-through charging function.
