Вам понадобится код для получения текущего разрешения. Затем вы можете добавить эти значения в запись [Icon], чтобы создать ярлык. Вот некоторый код для начала работы:
[Setup]
AppName=DisplayResoltution
AppVerName=DisplayResoltution
DefaultDirName=DisplayResoltution
DisableStartupPrompt=true
Uninstallable=false
[Files]
Source: "C:\util\innosetup\Examples\MyProg.exe"; DestDir: "{app}"; Flags: ignoreversion
; NOTE: Don't use "Flags: ignoreversion" on any shared system files
[Icons]
Name: "{group}\My Program"; Filename: "{app}\MyProg.exe"; Parameters: {code:GetParams}
