Does your monitor have alternate inputs (DVI, Analog) ... is the proper one selected as you have it hooked up?

(sorry if you have already checked this ... but sometimes we forget...)
 
Ive had this happen when using a non-apple adapter, but you may also want to check displays on system preferences. Is it registering the external monitor? If not then clearly its a cable issue...
 
Got Display to Work...

Thank you for your responses. I bought a mini displayport to dvi cable through monoprice... #5998 for anyone interested. Works great!!

Can you post the link to the cable you bought


I read somewhere that its best not to use hdmi with vga or dvi

Displayport has more compatibility
