Macbook Pro + External montior

I am trying to connect my Macbook Pro (late 2013) to an external monitor. I have done this before with no problems, but now when I try to connect it to a new monitor my macbook screen flashes on and off and will not connect. Help please!

MacBook Pro 13″, macOS 10.15
