You could try using third party software like dual monitor tools.
Though I haven't used it myself so I cannot say whether or not I'd recommend it.
And do keep in mind that with third party software that it could potentially cause harm if not downloaded correctly.
I don't know an official way of doing this, so the only option is probably third party software.
