It could be either or both. Is there a chance of borrowing a monitor off of a friend? That would tell you quickly. In the interim, have you checked connections at the monitor and the PC?

Another idea is to use a live DVD/usb and boot another version of Ubuntu, like 18.04. That would also rule out a software problem. But older hardware can fail and a cable is usually a low-cost way to exclude a source of problems.
