Best DisplayPort to VGA Adapter?

Hi All!

I'm currently working on a project that has a VGA monitor on it and trying to connect an Eos RPU. The monitor is a 1280x1024 and can accept the RPU. I have a currently have a StarTech DisplayPort to VGA Video Adapter Converter that doesn't seem the be displaying the image. Has anyone used this adapter and have found that it doesn't work? Is there a better one available that will work?
