How do I get out of a black screen on my Logik LOGDVD 358 DVD player?

I was setting up my LOGIK LOGDVD 358 DVD player for HDMI usage and set the resolution too high which has left me with a black screen!!!! There is no reset option (Duh!) and the book says "reconnect any available interlace video output to your display and re-adjust the resolution setting". What does that mean? Whats an interlace video output? Help!
