Screen Mirroring Oppo to PC or TV: How-To

To screen mirror an Oppo phone to a PC or TV, you use the built-in wireless display feature (often called Cast or Smart View) on the phone, and the receiving device must support Miracast or a similar standard. On a TV, you enable the screen mirroring mode in the TV’s input/source menu, then select the TV from your Oppo’s cast list. On a PC, you need Windows’ built-in wireless display receiver (available on Windows 10 and 11), which you activate by pressing Win+K and choosing “Connect to a wireless display.”

Background: What Screen Mirroring Is (and Isn’t)

Screen mirroring sends a live, real-time copy of your phone’s display to a larger screen. Every frame of your home screen, apps, videos, and games appears on the TV or PC monitor. It is different from casting (like Google Cast or Chromecast), where the phone sends a link or stream to the TV and the TV handles playback itself. With mirroring, the phone does all the work; with casting, the TV does the work after receiving the stream.

Oppo phones run ColorOS, which is based on Android. The mirroring function is built into the quick-settings panel, usually labeled “Cast” or “Smart View.” The underlying technology is Miracast, a peer-to-peer standard that uses Wi-Fi Direct to create a direct connection between the phone and the display. Because it is peer-to-peer, you do not need a router or internet connection—only both devices need to support Miracast.

How It Works: The Technology and Requirements

Miracast creates a direct Wi-Fi link between the sender (your Oppo) and the receiver (the TV or PC). It uses the Wi-Fi Direct protocol, which is like a mini Wi-Fi network between two devices only. The phone encodes the screen in H.264 video and sends it over this link. The receiver decodes and displays it.

Requirements for mirroring to work:

  • Oppo phone: Most Oppo models from the last several years support Miracast. Look for “Cast” or “Smart View” in the quick settings (swipe down twice to see all icons).
  • TV: The TV must have built-in Miracast or a separate Miracast adapter. Many smart TVs from 2015 onward include it, but the name varies: “Screen Mirroring” on LG, “Screen Share” on Roku, “Miracast” on Sony, and “Wireless Display” on some models.
  • PC: Windows 10 and 11 have a built-in wireless display receiver, but it is not enabled by default on all PCs. You need to install the “Wireless Display” optional feature from Windows Settings (Settings > System > Optional Features > Add a feature > search for “Wireless Display”).
  • Same Wi-Fi network (for some methods): Miracast itself does not need a network, but some TV brands require both devices to be on the same Wi-Fi network for discovery. If your TV asks for a network, connect both to the same router.

How to Mirror to a TV (Step-by-Step)

Exact menu names vary by Oppo model and ColorOS version, but the general flow is consistent:

  1. Turn on your TV and switch its input/source to the screen mirroring mode. On most TVs, this is in the input/source list (e.g., “Screen Mirroring,” “Screen Share,” “Wi-Fi Direct,” or “Miracast”). If you cannot find it, check the TV’s manual or look for a “Screen Mirroring” app on the TV’s home screen.
  2. On your Oppo, swipe down from the top to open the quick settings panel. Swipe down again to see all icons.
  3. Look for “Cast,” “Smart View,” or “Screen Mirroring” (the icon looks like a rectangle with a Wi‑Fi symbol). Tap it.
  4. Your phone will scan for available devices. Tap the name of your TV when it appears.
  5. If the TV shows a PIN or confirmation prompt, enter the PIN on your phone or confirm on the TV.
  6. The phone screen will appear on the TV. To stop, go back to the Cast menu and tap “Disconnect.”

If your TV does not appear, try the following:

  • Make sure the TV is not already connected to another device.
  • Restart both the phone and the TV.
  • If your TV requires a Wi-Fi network, connect both to the same network.
  • Check if your TV has a separate “Screen Mirroring” app that needs to be opened first.

How to Mirror to a PC (Step-by-Step)

Windows 10 and 11 can act as a Miracast receiver, but you must enable it first.

  1. On your PC, open Settings > System > Optional Features (Windows 11) or Settings > System > Apps & features > Optional features (Windows 10).
  2. Click “Add a feature” (or “Add an optional feature”).
  3. Search for “Wireless Display,” select it, and click “Install.”
  4. Once installed, press the Windows key + K on your PC. A panel will appear on the right side of the screen.
  5. Select “Connect to a wireless display.” The PC will now wait for a connection.
  6. On your Oppo, open the Cast menu (as above) and select your PC’s name from the list.
  7. Accept the connection on the PC if prompted.

If the PC does not show up, check that your PC’s Wi-Fi adapter supports Miracast. Most laptops and many desktops do, but some older or budget models do not. You can check by pressing Win+R, typing dxdiag, and looking at the “Miracast” line under the Display tab.

Common Problems and How to Fix Them

  • No devices found: Both devices must support Miracast. If your TV is older, it may not. For PCs, the Wireless Display feature must be installed. Also, make sure both devices are on the same Wi-Fi network if your TV requires it.
  • Lag or stutter: Mirroring is sensitive to interference. Move closer to the TV or PC, and turn off other Wi-Fi devices that might interfere. For video, the phone does the decoding, so a low-end phone may struggle.
  • No sound: Some TVs require you to select the correct audio input. On the PC, check that the sound output is set to the PC’s speakers or the TV if it uses HDMI. On the phone, make sure media volume is not muted.
  • Connection drops after a few minutes: This can happen if the TV’s power-saving mode turns off the Wi-Fi receiver. Disable power saving on the TV’s network settings.
  • Phone screen is black on the TV: Some apps (like Netflix or DRM-protected video) block mirroring. This is a copyright protection feature. You cannot mirror those apps; use the app’s built-in cast feature instead.

Alternatives to Built-in Mirroring

If your TV or PC does not support Miracast, you have other options:

  • Chromecast or Android TV: These use Google Cast, which is not the same as mirroring. You can cast supported apps (YouTube, Netflix) directly, but for mirroring the whole screen, you use the “Cast screen” option in the Google Home app. This works on Oppo phones because they support Google services.
  • HDMI cable: A USB-C to HDMI cable connects your Oppo directly to the TV or monitor. This gives the lowest latency and works with every TV that has HDMI. Not all Oppo models support video output over USB-C, though. Check your phone’s specifications.
  • DLNA: Some TVs support DLNA, which lets you send media files (photos, videos) to the TV, but it does not mirror your screen. You would need a DLNA app on your phone.
  • Third-party apps: Apps like AirDroid or TeamViewer can mirror to a PC over the internet, but they require installing software on both devices and may have latency. They are not true Miracast.

Frequently Asked Questions

Why doesn’t my Oppo show the “Cast” option?
Some ColorOS versions hide the Cast button in the quick settings. Swipe down twice to see all icons, then tap the pencil/edit icon to add “Cast” if it is missing. If it is not there at all, your phone may not support Miracast—check the Oppo website for your model’s specifications.

Can I mirror to a PC without installing anything?
No. Windows does not have the receiver enabled by default. You must install the “Wireless Display” optional feature. After that, no extra software is needed.

Does screen mirroring work without internet?
Yes, Miracast uses Wi-Fi Direct, which creates a direct connection between the phone and the TV/PC. You do not need a router or internet. However, some TV brands require both devices to be on the same Wi-Fi network for discovery, so you may need a router for the initial connection.

Why is there a delay between my phone and the TV?
Miracast typically has a latency of 100–300 ms. This is fine for videos and presentations but not for fast-paced games. For gaming, use a USB-C to HDMI cable for the lowest latency.

Can I mirror Netflix or other streaming apps?
Often, no. Many streaming apps use DRM (digital rights management) that blocks screen mirroring. You will see a black screen or an error. Instead, use the app’s built-in cast feature (like the cast icon in Netflix) if your TV supports it.

Does mirroring drain the phone battery quickly?
Yes, mirroring uses the phone’s CPU, GPU, and Wi-Fi radio heavily. Keep the phone plugged in during long sessions.
