How to change Monitorsignal to vga?

Hi...

I´ve bought a used Power Mac G4 without Monitor. The reason for the deal was, to use the Mac due to the existing PCI-Interfaceboard for a Digitalback Sinar23 HR which is mounted on a Hasselblad Kamera 553 ELX . As I´m not familiar with Applecomputers, I´ve connected the Mac to the VGA-Port of an Acer 21" LCD-Monitor. Keyboard and mouse are original Appleproducts. After switching the Mac on, at the monitor display only a little blue field with "Input Not supported".

What can I do, to make the monitor working?

PowerMac, Mac OS 9.1.x

Hmmm, which G4 & video card exactly? What port on the Video card? What kind of Cable is it?

I wonder if "Input Not supported" might mean Resolution not supported?

Try a Safe Boot, holding Shift key at bootup, if you get a screen, try setting the resolution?
