You want to watch movies with Xiaomi Redmi 8 on the big screen, but you don’t know how to connect your phone to your TV? This article will help you choose the best method depending on your TV model, availability of additional devices and picture quality requirements. We will analyze all the current methods, from wireless technologies to wired adapters, point out typical errors and give recommendations for setting up for minimal video delay.

Redmi 8 (codenamed olivelite) is designed to support Miracast and Google Cast, but does not have a built-in version. HDMI-This means that wired connections require adapters, and wireless connections require compatibility with your TV's protocols, and in this article you'll find a comparative table of methods for speed, quality and complexity of settings, as well as instructions for specific firmware. MIUI for this model.

1. Wireless Wi-Fi connectivity (Miracast and Google Cast)

The most popular way is to transmit images over the air. Redmi 8 supports two protocols:

• 📶 Miracast – Direct TV connection without router (requires TV support).
• 📡 Google Cast (Chromecast) – streaming via router to devices with Google TV or Chromecast.

For Miracast:

1. Open Settings → Connections and Sharing → Wireless display.
2. Turn on device search and select your TV from the list.
3. Confirm the connection on both devices.

For Google Cast:

1. Connect your phone and TV to the same Wi-Fi network.
2. In the YouTube or Google Photos app, click the broadcast icon (📺).
3. Select your target device (TV or Chromecast).

⚠️ Note: When using Miracast on Redmi 8, image artifacts are possible at the resolution above 720p. This is a limitation of the Qualcomm Snapdragon 439 hardware platform.

2. Wired connection via USB-C → HDMI adapter

If wireless methods are late, use a wired adapter. Redmi 8 is fine.

• 🔌 USB-C → HDMI (It requires support for DisplayPort Alt Mode, which is not available in this model).
• 🔄 USB-C → USB-A + OTG-cable (for TV with USB-port, but only for photo/video, not for streaming).
• 📱➡️📺 MHL-Adapter (Old Standard, not supported by Redmi 8).

Important: Xiaomi Redmi 8 does not support direct HDMI video transmission via USB-C due to the lack of a DisplayPort Alt Mode chip in the processor. The only working option is to use a USB-OTG + application for local playback (such as VLC or MX Player) on TV with support for media files.

3. DLNA/UPnP connection (for local files)

If you want to stream movies that you've already downloaded, rather than streaming from the Internet, use DLNA. On Redmi 8, this works like this:

1. Install BubbleUPnP or LocalCast.
2. Connect your phone and TV to the same network.
3. In the application, select a file and click "Play on..." → select TV.

Limitations of the method:

• ⏳ Large latency (up to 500ms) – not suitable for games or interactive content.
• 📁 It only works with local files (not streaming services).
• 🔄 Needs support DLNA TV (check in the network settings).

4. Use of the console (Chromecast, Xiaomi Mi TV Stick, Fire TV)

If your TV doesn't support modern protocols, buy an external console. For Redmi 8, the best options are:

• 📱 Xiaomi Mi TV Stick (optimized for the ecosystem) MIUI, price ~3000₽).
• 🔥 Amazon Fire TV Stick (supports Miracast, price) ~4000₽).
• 🌐 Google Chromecast (best compatible with Google Cast, price) ~3500₽).

Instructions for Mi TV Stick:

1. Connect the console to the HDMI-port TV and set up Wi-Fi.
2. On Redmi 8, open Settings → Connections → Wireless display.
3. Select Mi TV Stick from the list.
4. Run the movie in any app (like Kinopoisk HD) and click the broadcast icon.

⚠️ Note: When using Fire TV Stick may need to disable battery optimization for the Miracast app on Redmi 8. → Annexes → Application management → Wireless display → Battery → No restrictions.

5. Solving Connection Problems

If the image is not transmitted or artifacts appear, check:

Telephone and TV connected to the same Wi-Fi network (for Google Cast/DLNA)

Common mistakes and ways to eliminate them:

6.Optimizing for streaming movies

To reduce delay and improve quality:

• 📶 Use a router with Wi-Fi 5 support (802.11ac) 5GHz.
• 🔧 In Redmi 8 settings, turn off Adaptive Brightness and Autoturn – they create additional load.
• 🎬 For streaming services (Netflix, Kinopoisk) use Google Cast, not Miracast – it is better optimized for video.
• 🔋 Connect your phone to charge – performance restriction when battery power is low can cause lags.

For advanced users: If you have root access on Redmi 8, you can force 1080p support on Miracast by editing /system/build.prop:

ro.sf.lcd_density=440


persist.debug.wfd.enable=1




persist.sys.wfd.virtual=0

After the changes, restart the device. This method only works on MIUI 11-12 firmware and can cause system instability.

💡

If you watch movies from your phone to TV often, create a separate 5GHz Wi-Fi hotspot on your router specifically for streaming, which will reduce the impact of other devices on the transmission speed.

7. Alternative methods (for older TVs)

If your TV is released before 2015 and does not support modern protocols:

• 📼 AV-cable (3.5 mm) → RCA) — Connects to the phone’s audio output (quality) 480p, delay of 200-400 ms).
• 🖥️ Streaming via PC – broadcast the screen of the phone to the computer USB (Scrcpy app, and from PC to TV on HDMI.
• 💽 flash drive or external HDD — Download movies to your phone and then copy to the drive for playback on TV.

For AV-cable:

1. Buy a USB-C → 3.5mm jack adapter (if it’s not included in the Redmi 8 package).
2. Connect the cable to the phone and RCA-TV inputs (yellow – video, red / white – audio).
3. On the phone, turn on media transmission in the sound settings.

⚠️ Attention: When in use AV-Redmi 8 cable will discharge faster due to the additional load on the audio output.
