macbook pro will not recognize external monitor

[jstech]

connected macbook pro to external monitor (tried this with 2 different external monitors)
external monitor stayed black
went to system preferences-displays- macbook was set for mirroring. mirroring did not occur. unset for mirroring- extend did not occur- reset for mirroring- nothing happened. hit detect displays- nothing else happened. tried with and without dvi adapter- vga analog- and the macbook still doesn't like the external monitors. could it be that the video card is bad? or the connector?

It's possible the cable is bad or monitor is. You'd have to use different cables to see.

macbook pro will not recognize monitor

adpter into vga cable into tv (dvi to vga adapter) didn't wprl
disconnected adapter and connected pc- monitor worked
took working computer monitor, hooked it up to dvi adapter- didn't work.
dvi to dvi cable- hooked to computer monitor. removed adapter and went directly in- did not work. tried resetting machine to mirror several times
my suspicion-no output from video card.

Just saw this post of yours. I think you should take it to the store and get it checked. It might be a bad video port.
