In case folks have forgotten, this is the venerable ShowWin() solution 
which Herbert Kleebaurer kindly provided many years ago & which works well.

I used Herbert's method until I realized there was a default "no-console" 
method for launching scrcpy, where the difference in the two methods are
 a. The ShowWin() method flashes and then hides the console from view
 b. The VBS no-console method launches scrcpy without a console window

For the record, here's Herbert's ShowWin() method which has worked for 
years where this is the version I used with USB (before adb Wi-Fi).

  REM
  REM  Download screencopy onto your PC <https://scrcpy.org/>
  REM  Set Android "Developer Options" "USB debugging = On"
  REM  Then plug the Android phone into the USB port of Windows
  REM  Then run "scrcpy -s SERIALNUMBER" on the Win/Mac/Linux PC
  REM  This will mirror Android onto your Win/Mac/Linux PC
  REM  But scrcpy leaves an annoying console behind, by default
  REM  The entire point of this script is to run that one command
  REM  But WITHOUT leaving an empty console behind on Windows.

  REM C:\app\editor\android\scrcpy\showwin.bat
  REM adb mdns services

  REM embedded certificate block is an executable encoded within the batch file!
  REM Extract embedded executable from script using certutil decode
  REM Reads the batch file itself (%~f0) as encoded source content
  REM Decodes certificate block at the bottom and writes showwin.exe
  REM -f forces overwrite if showwin.exe already exists
  REM Output is suppressed using >nul to keep console clean
  REM showwin.exe is used to hide the console window temporarily
  REM The batch file launches scrcpy to mirror your phone.
  REM Normally, this leaves a blank console window hanging open.
  REM The command showwin.exe 0 is run right after launching scrcpy.
  REM This executable finds the console window and hides it from view.
  REM When you're done and close scrcpy, the script runs showwin.exe 5
  REM which makes the console visible again briefly to clean up.
  REM Showwin searches for the window with the class "ConsoleWindowClass" 
  REM (that's how Windows identifies command windows).
  REM Uses a system call (like ShowWindow() in Win32 API) to make it invisible.
  REM It doesn't actually kill or close the window.
  REM It just makes it vanish visually while scrcpy runs
  REM So you’re left with a clean screen showing only your mirrored phone.
  certutil -f -decode %~f0 showwin.exe>nul
  REM Port 5555 was needed when you established adb connections over USB
  REM And then you disconnected the USB cable to subsequently work on Wi-Fi
  REM But as of Android 11 or 12, you can establish the connection over Wi-Fi
  REM But that "Developer option" "Wireless debugging" port is assigned by Android!
  REM So you have to get it on Android or on Windows to know what it is 
  REM adb connect 192.168.1.3:5555
  REM You can get the current port from the following command
  REM c:\> netstat -ano -p tcp | findstr "192.168.1.3"
  REM
  REM maybe we do NOT need this command after all???
  REM adb connect 192.168.1.3:41913
  REM
  :: now we hide console window
  showwin.exe 0
  REM
  REM scrcpy --always-on-top --tcpip=192.168.1.3:5555
  REM Maybe we can then remove the IP:PORT after all???
  REM scrcpy --always-on-top --tcpip=192.168.1.3:41913
  REM We don't really need --always-on-top after all???
  REM scrcpy --always-on-top
