How do I cast from Windows 10 to Mi TV?

Hi there! Casting your Windows 10 laptop or desktop to a Mi TV is a great way to enjoy your computer‘s videos, games, apps and more on the big screen. In this comprehensive guide, I‘ll explain multiple ways to wirelessly connect your Windows 10 device to a Mi TV for screen mirroring, along with tips to fix any issues that arise. Let‘s get started!

Casting Technology Explained

The main wireless technologies used for casting from Windows 10 to TVs are:

Miracast – This direct WiFi connection method allows instant casting between supported Windows PCs and compatible TVs without a router. It creates a peer-to-peer connection using WiFi Direct to transmit up to 1080p video and 5.1 surround sound audio. Both your Windows device and the TV must have Miracast implemented in hardware or software to work. Miracast adoption is now over 250 million devices worldwide according to WiFi Alliance estimates.

Chromecast built-in – The popular Chromecast technology from Google allows easy casting from Chrome browser on laptops or smartphones to smart TVs. The TV must have built-in Chromecast which acts as a receiver for the casted content. This uses your existing WiFi network. According to Google, over 100 million Chromecast devices have been sold globally.

Wireless HDMI – Uses adapters to convert HDMI source from your laptop to a wireless stream sent over WiFi to the TV or receiver box plugged into the TV. Useful if your devices don‘t support casting protocols. Provides full HD 1080p resolution and 5.1 surround audio.

Enabling Casting on Your Windows 10 Device

Let‘s get your Windows 10 laptop or desktop ready for casting:

Open Settings > System > Projecting to this PC and turn off the toggle for "Projecting to this PC." This ensures your computer can project outwards.
Go to Settings > Devices > Bluetooth & other devices. Turn on "Available for projection" and enable the wireless display option here.
In Windows search, open the Connect app. Go to "Connect to a wireless display" and see if your TV shows up as a connection option now. If yes, then your Windows PC is ready to cast!
You can also check if your WiFi adapter supports Miracast by typing "netsh WLAN show drivers" in Command Prompt. If Wireless Display is listed as Supported = Yes, then you‘re good to go.

Connecting Your Windows 10 Computer to a Mi TV

Once wireless casting is enabled on your side, connecting to a Mi TV is straightforward:

On your Mi TV, open the Settings app and go to Connection > Wireless Projection. Enable the toggle for wireless display/Miracast sharing.
Now on your Windows 10 laptop or desktop, open Quick Settings via the Notification Center icon on the taskbar. Click on "Cast" or connect via the Connect app.
The TV should show up as a connection option. Select it and confirm the pairing code on your TV to establish the Miracast session.
Your Windows screen will now be duplicated on the Mi TV. Enjoy casted videos, browsing and more on the big screen!

Troubleshooting Casting Problems

If your Mi TV isn‘t detected during the casting process or the connection is laggy, try these troubleshooting tips:

Ensure Miracast or wireless display is enabled on both the Windows 10 device and the TV. Toggle the options off and on again if needed.
Connect your laptop and TV to the same 5GHz WiFi network for faster speeds. Avoid 2.4GHz networks. Or use Ethernet to your TV if possible.
Update your Windows 10 laptop‘s WiFi, graphics drivers and Miracast adapters to the latest versions.
Adjust the Miracast channel/frequency band in Connect app > Advanced options if needed.
Try a Miracast repeater or wireless HDMI adapter if your laptop‘s hardware is the issue.
Factory reset your Mi TV and set up Miracast again from scratch if needed.

Comparing Casting Methods for Windows 10

Let‘s look at a comparison of the main casting options:

Method	Latency	Compatibility	Video Quality	Audio Quality
Miracast	Low	Requires supported hardware	Up to 1080p HD	Stereo or 5.1 surround
Chromecast built-in	Very Low	Requires Chromecast TV	Up to 4K	Stereo
Wireless HDMI	Low	Works with any TV	Up to 1080p HD	5.1 surround

As you can see, each casting method has its own pros and cons. Miracast provides the most widely compatible peer-to-peer casting with great latency, but requires specific hardware support. Chromecast is easy to use from Chrome browser with minimal lag, but maxes out at 1080p resolution. Wireless HDMI is a universal solution that works with any TV but requires buying an adapter.

Optimizing Windows 10 for casting

To reduce latency while casting your Windows 10 screen, try these tips:

Set your WiFi adapter to use only the 5GHz band for higher throughput to your router and TV.
Under Display settings, enable GPU scaling for sharper image quality. Turn off low power mode for the best graphics performance.
Adjust the screen refresh rate to 30Hz or lower. 60Hz requires higher bandwidth and may cause lag.
In the registry editor, increase the WirelessDisplayBitrateMax value under Miracast to boost bandwidth allocation. But keep it under 50Mbps.

Advanced Casting Tips for Windows 10 Power Users

For enthusiasts who want greater customization and control while casting from Windows 10, here are some handy tips:

Use the Miracast Bandwidth Tool app to adjust audio and video bandwidth allotment in real-time as per your requirements.
Install Chromecast browser extensions on Chrome like Castbuddy or Google Cast to enhance the casting experience with better media controls and multi-screen options.
Set up Plex or Kodi home media server on your Windows 10 desktop to cast local video files and content to the Mi TV. Great for personal media libraries.
Use Steam Link Anywhere to cast and play games from your Windows gaming rig on the Mi TV for a big-screen gaming experience. Reduce in-game resolution if needed.
For screen recording while casting, use apps like Screencast-O-Matic which can capture your on-screen activity into a video file.

Casting for Entertainment with Chromecast built-in

Many Mi TV models come with Chromecast built-in, allowing seamless content casting from Chrome browser:

Connect your Windows 10 laptop and the Mi TV to the same WiFi network. Use 5GHz WiFi or Ethernet if possible.
Install the Google Chrome browser from https://www.google.com/chrome if you don‘t already have it.
Open a Chrome tab and tap the Cast icon. Select your Mi TV from the target device list.
Your current Chrome tab will now be cast to the TV. Or tap "Cast desktop" to mirror everything on your Windows screen.
Open web apps like Netflix, YouTube, Spotify within Chrome and tap the Cast button in each app to cast that video or audio to your TV!

Chromecast utilizes your WiFi network to transmit screen data with very low latency. This works reliably for casting streaming media and browser tabs. The video and audio quality is dependent on your network bandwidth.

With Chromecast built-in, you can cast to your Mi TV not only from Windows laptops but also from any iPhone, Android phone or tablet using compatible apps!

The Future of Wireless Casting

Casting technology for Windows 10 is only getting better:

WiFi 6 will enable faster video streaming with higher throughput and less congestion. This will improve casting speeds and performance in the future.
Miracast improvements like tunneled direct link setup are coming to provide faster connection times between your devices.
New wireless display standards like WiFi CERTIFIED Miracast and Miracast 2.0 aim to make casting more seamless across platforms.

So you can look forward to an even better casting experience from Windows 10 laptops/desktops to smart TVs!
