How to transfer an image from Xiaomi Redmi 9 to a TV: all working ways

Broadcasting the screen from Xiaomi Redmi 9 to a TV opens up new possibilities for watching videos, games and presentations on the big screen. However, not everyone knows that 5 different methods are available for this model, from wireless protocols to wired connection. The main problem is that the choice of the optimal way depends on the version of MIUI, the model of the TV and even the type of content.

In this article, we’ll break down each method with the Redmi 9 (codenamed lancelot), including the hidden Developer Options settings that are often overlooked in standard instructions, learn how to get around the limitations of MIUI 12/13 when broadcasting secure content (Netflix, Disney+), why Wi-Fi Direct is more stable than Miracast on budget TVs, and how to use your phone as a remote after you connect.

1. Wireless broadcast via Miracast (Screen Mirroring)

Miracast is a wireless broadcasting standard built into Redmi 9 at the Android 10 level.It doesn't require an internet connection, but has strict compatibility requirements: both devices must support Wi-Fi Display (on TV, it can be called Screen Mirroring or AllShare Cast).

On Redmi 9, the feature is hidden in the Settings menu → Connection and Sharing → Broadcast (Cast). Importantly, if there is no Translation item, then the TV manufacturer has blocked Miracast at the firmware level (relevant to some models of the Xiaomi TV A2 2021), in which case try alternative methods from the following sections.

• ✅ Pros: Minimum delay (up to 50 ms), no link to the router
• ❌ Cons: Does not work with DRM-Protected content (Netflix, Amazon Prime), artifacts are possible with a weak signal
• 🔧 Requirements: TV with Miracast support (check the model instructions), Android 10+ phone-on

⚠️ Attention: Redmi 9s MIUI 12.5 and later Miracast can automatically shut down after 10 minutes of inactivity. To avoid this, activate the developer mode (Settings) → The phone. → Version. MIUI — Click 7 times and turn off the Wi-Fi Display Auto Disable option in Developer Options.

Wi-Fi Direct is an alternative to Miracast, which creates a direct network between your phone and your TV, a method that works best for the Xiaomi Redmi 9 if your TV doesn’t support Miracast but has Wi-Fi Direct (often found on Xiaomi Mi TV 4S and Redmi Smart TV models).

Instructions:

1. On TV: Settings → Network → Wi-Fi Direct → Enable
2. On the phone: Settings → Wi-Fi → Additional → Wi-Fi Direct
3. Select your TV name from the list and confirm the connection
4. Run the stream through the app (e.g. Google Home or Mi Remote)

A key difference from Miracast: Wi-Fi Direct allows you to stream audio and video separately, which is useful for streaming music to TV speakers. However, latency can reach 200 ms — critical for gaming, but not noticeable when watching movies.

If the TV doesn’t appear in the Wi-Fi Direct list, try restarting both devices and temporarily disabling Bluetooth – it can cause interference at 2.4GHz.
