PSA:
How to mirror modern Android onto your PC using scrcpy & adb over Wi-Fi
(Works on Android 11 and up)

Windows or Linux, this mirrors your phone on your PC monitor two feet tall. (The keyboard, mouse, clipboard, speakers all mirror Android over Wi-Fi).

1. Connect your phone to the LAN
2. Longpress the Wireless Debugging tile at the top of your homescreen
3. Note the "IP address & Port", for example
a. IP address (e.g., 192.168.1.2)
b. Connection Port (e.g., 46003)
3. Tap "Pair device with pairing code" to get another port & pairing code
a. IP address (e.g., 192.168.1.2)
b. Pairing Port (e.g., 40005)
c. Pairing code (e.g., 450824)
4. Pair & connect:
adb pair 192.168.1.2:40005 450824
adb connect 192.168.1.2:46003
5. Run scrcpy without leaving an unusable console behind:
Windows: scrcpy-noconsole.vbs (see below)
Linux: mirror (see below)

6. That mirrors Android on your monitor while using the PC mouse, keyboard,
speakers & clipboard to control the device full-height on your monitor.

For Linux, this mirrors Android thereafter without the console locking up:
alias mirror ='scrcpy --keyboard=sdk --always-on-top &'

This is the default Windows scrcpy-noconsole.vbs shipped with scrcpy.
strCommand = "cmd /c scrcpy.exe"
For Each Arg In WScript.Arguments
strCommand = strCommand & " """ & replace(Arg, """", """""""""") & """"
Next
CreateObject("Wscript.Shell").Run strCommand, 0, false

I modified it slightly to reduce one step when using the Android keyboard.
' strCommand = "cmd /c scrcpy.exe"
strCommand = "cmd /c scrcpy.exe --keyboard=sdk --always-on-top"
For Each Arg In WScript.Arguments
strCommand = strCommand & " """ & replace(Arg, """", """""""""") & """"
Next
CreateObject("Wscript.Shell").Run strCommand, 0, false

There is minor one-time setup, such as turning on Developer Options in the phone to enable "USB debugging" & "Wireless debugging" & adding the wireless-debugging tile which you do only once in the life of the phone.

Note once you have paired a device, you usually only need the adb connect command in the future, especially with a static IP address.
adb connect
scrcpy-noconsole.vbs (for Windows)
mirror (for Linux

There are, of course, a billion options, but this is a quickie for all.
And there is the old-school way of using adb connect 192.168.1.2:5555

If you're tapping on your phone while at your desk, you're not efficient.

There are three ways to connect your phone to your PC to control it from
the PC (& which can makes the phone as tall & as wide as your monitor is).

1. Wi-Fi
2. USB
3. Hybrid USB + Wi-Fi

We covered the Wi-Fi steps prior, which work only on Android 11+.

The USB method is the simplest (and most reliable) overall.
a. Connect the phone to the PC via USB
b. adb devices
c. scrcpy --always-on-top --full-screen --stay-awake --keyboard=sdk

For all Android versions, including older Android, there's a half-and-half
a. Connect the phone to the PC via USB
b. adb tcpip 5555
c. adb connect 192.168.1.2:5555
d. scrcpy --always-on-top --full-screen --stay-awake --keyboard=sdk

In my humblest of opinions, if you're at your PC, there's no reason to
touch the phone in order to do whatever it is that you want to do with it.

Note there are a billion scrcpy options, so those are just examples.
