Currently, there are dozens of apps that allow mirroring Android phones on PC, but only a handful of them are really good. From occasional jerks to high latency to intrusive ads; not to mention that Android screen mirroring on PC is one big nightmare.
Scrcpy is one of the best screen mirroring tools for Android. It allows you to mirror your Android phone on your PC and control it directly with PC peripherals like keyboard and mouse. Scrcpy supports seamless copy and paste between your phone and PC, works on both Macs and Windows PCs, and is also absolutely free.
However, it requires an understanding of how to use the ADB command line. If you are an advanced developer, you may already know Scrcpy, but if you are a beginner trying just to mirror his/her phone, this guide will enlighten you step by step and teach you how to use Scrcpy for Windows.
Some basic features of Scrcpy:
- mirroring with device screen off
- copy-paste in both directions
- configurable quality
- device screen as a webcam (V4L2) (Linux-only)
- physical keyboard simulation (HID) (Linux-only)
- and more…
It focuses on:
- lightness: native, displays only the device screen
- performance: 30~120fps, depending on the device
- quality: 1920×1080 or above
- low latency: 35~70ms
- low startup time: ~1 second to display the first image
- non-intrusiveness: nothing is left installed on the device
- user benefits: no account, no ads, no internet required
- freedom: free and open source software
The Android device requires at least API 21 (Android 5.0).
Make sure you enabled adb debugging on your device(s).
On some devices, you also need to enable an additional option ()to control it using keyboard and mouse.
How to mirror Android screen to PC via USB?
- Firstly, go to Settings > About phone > Scroll down and find Build Number > Tap on it several times to enable developer settings.
- USE THIS GUIDE IF YOU ARE USING MIUI (How to enable Developer Options)
- Go to Settings > System > Developer Options, then enable it from top. (How to enable Developer Options)
- Next, scroll down to find usb debugging and enable it.
- Now, connect your device to your PC via USB cable and allow USB Debugging.
- Next, go back to your PC and download the latest Scrcpy build from this link (direct) and extract it into a folder.
- Then, while your device is connected to your PC with USB Debugging enabled and allowed, double click “scrcpy.exe” inside the folder.
- If you did every step correct, you should be seeing these after waiting couple of seconds:
- Finally, you are now mirroring your phone screen to your PC. Furthermore, you can use your mouse and keyboard to control the device!
- That’s it. Next time, you can just connect your phone to your PC and directly open Scrcpy from its folder.

Sometimes, it is useful to mirror an Android device at a lower definition to increase performance.
To limit both the width and height to some value (e.g. 1024):
scrcpy --max-size 1024 scrcpy -m 1024 # short version
The other dimension is computed to that the device aspect ratio is preserved. That way, a device in 1920×1080 will be mirrored at 1024×576.
The default bit-rate is 8 Mbps. To change the video bitrate (e.g. to 2 Mbps):
scrcpy --bit-rate 2M scrcpy -b 2M # short version
Limit frame rate
The capture frame rate can be limited:
scrcpy --max-fps 15
This is officially supported since Android 10, but may work on earlier versions.
The device screen may be cropped to mirror only part of the screen.
This is useful for example to mirror only one eye of the Oculus Go:
scrcpy --crop 1224:1440:0:0 # 1224x1440 at offset (0,0)
--max-size is also specified, resizing is applied after cropping.
Lock video orientation
To lock the orientation of the mirroring:
scrcpy --lock-video-orientation # initial (current) orientation scrcpy --lock-video-orientation=0 # natural orientation scrcpy --lock-video-orientation=1 # 90° counterclockwise scrcpy --lock-video-orientation=2 # 180° scrcpy --lock-video-orientation=3 # 90° clockwise
This affects recording orientation.
The window may also be rotated independently.
It is possible to record the screen while mirroring:
scrcpy --record file.mp4 scrcpy -r file.mkv
To disable mirroring while recording:
scrcpy --no-display --record file.mp4 scrcpy -Nr file.mkv # interrupt recording with Ctrl+C
“Skipped frames” are recorded, even if they are not displayed in real time (for performance reasons). Frames are timestamped on the device, so packet delay variation does not impact the recorded file.
If several devices are listed in
adb devices, you must specify the serial:
scrcpy --serial 0123456789abcdef scrcpy -s 0123456789abcdef # short version
If the device is connected over TCP/IP:
scrcpy --serial 192.168.0.1:5555 scrcpy -s 192.168.0.1:5555 # short version
You can start several instances of scrcpy for several devices.
By default, the window title is the device model. It can be changed:
scrcpy --window-title 'My device'
Position and size
The initial window position and size may be specified:
scrcpy --window-x 100 --window-y 100 --window-width 800 --window-height 600
To disable window decorations:
Always on top
To keep the scrcpy window always on top:
The app may be started directly in fullscreen:
scrcpy --fullscreen scrcpy -f # short version
Fullscreen can then be toggled dynamically with MOD+f.
The window may be rotated:
scrcpy --rotation 1
Possibles values are:
0: no rotation
1: 90 degrees counterclockwise
2: 180 degrees
3: 90 degrees clockwise
Other mirroring options
To disable controls (everything which can interact with the device: input keys, mouse events, drag&drop files):
scrcpy --no-control scrcpy -n
To prevent the device to sleep after some delay when the device is plugged in:
scrcpy --stay-awake scrcpy -w
The initial state is restored when scrcpy is closed.
Turn screen off
It is possible to turn the device screen off while mirroring on start with a command-line option:
scrcpy --turn-screen-off scrcpy -S
For presentations, it may be useful to show physical touches (on the physical device).
Android provides this feature in Developers options.
Scrcpy provides an option to enable this feature on start and restore the initial value on exit:
scrcpy --show-touches scrcpy -t
Note that it only shows physical touches (with the finger on the device).
To install an APK, drag & drop an APK file (ending with
.apk) to the scrcpy window.
There is no visual feedback, a log is printed to the console.
Push file to device
To push a file to
/sdcard/Download/ on the device, drag & drop a (non-APK) file to the scrcpy window.
There is no visual feedback, a log is printed to the console.
The target directory can be changed on start:
