A:AnswerHello and thank you for your question. Yes, you can add an additional monitor to this HP 27" all-in-one desktop. You will need a HDMI cable which is widely available everywhere as well as from the store you're shopping at.
A:AnswerNo, this All-In-One computer does not have an optical (CD) drive. You can look into external options, just make sure that it is compatible with the OS by looking at the manufacturer's website and that this unit meets the system requirements.
