You just need to connect the monitor is that correct?
Most likely you need a DVI to VGA adapter like this one here https://www.amazon.com/HDE-DVI-DVI-I-male-Cable/dp/B002IWP87S/ref=sr_1_3?s=aht&ie=UTF8&qid=1473777278&sr=1-3&keywords=vga+to+dvi
Have a look at that and let me know if that looks correct to what you are seeing.
