extra VGA is detected by imac G5 but is Blank

[punkpervert]

HI there,

Well annoyed as i recently changed my whole room set up so desk is one side of room and routed all of the cables so i have a VGA monitor by the bed to watch 24 and prison break in bed but disaster....it won't work!

purchased a mini vga to vga cable as i have a non intel G5 i mac and plugged it in. The vga screen is functioning as before i connected i got a 'no signal message' i plugged it in and the resolution on my mac changed automatically. Didin't think it would do this...i want the VGA to mirror my mac not other way round. But all academic as the VGA is black.

any ideas?
