VBA Display Both Screen Resolutions For Dual Monitors?

I am trying to create a macro that checks and displays the screen resolution for both the Main monitor and the secondary monitor.

Currently I have this code that displays the resolution on the main screen only:

Declare PtrSafe Function GetSystemMetrics32 Lib "User32" _
Alias "GetSystemMetrics" (ByVal nIndex As Long) As Long
Sub ScreenRes()
Dim lResWidth As Long
Dim lResHeight As Long
Dim sRes As String
lResWidth = GetSystemMetrics32(0)
lResHeight = GetSystemMetrics32(1)
sRes = lResWidth & "x" & lResHeight
MsgBox sRes
End Sub

However I want to then display another message with the secondary display's resolution (or on the same message box).
