VGA Output Issue

Strange issue here.

I have 2 laptops (Dell XPS M1210 and XPS M1710) that will not display through the VGA out port when connected to ceiling mounted projectors in our offices.  However, they DO work fine when connected to portable projectors we have.

I have toyed with every possible option through the NVIDIA control panel on both laptops with no success.

It is only on these 2 particular laptops, both with all latest driver and Windows updates.

Anyone have any possible ideas?

I don't see any way in which it could be related to the projectors.

Just guesing - well if they are laptops then maybye they have some sort of energy saving scheme that gives a bit lower signals, and, as they are wall mounted projectors, maybye the total voltage drop on connecting wires is so high, that the projector chip on the other side assumes all clock (hsync, vsync) signals not as 1-es but as 0s.. I suggest that if it is possible then try to get ladder and connect laptop to projector with short standart 6 ft cable and see if it works..

Another thing to try is to turn on the notebook and shut the lid right away. That way it will auto default to the external screen. See if the bios shows up on the projector. If it doesn't it is a signal issue, if it does it is a driver setting in windows.

On a side note, both laptops also work fine when connected to an external VGA monitor, so, it must somehow be related to the connections in our ceiling mounted projectors.  However, I don't know why these 2 specific laptops wouldn't work, but all others do.

If thats the case I'd recomend getting a vga amplifier for the notebooks. They start at 30 bucks and will boost the signal comming from the notebook.

Intalling beta driver direct from NVIDIA has solved the issue.
Driver available on Dell's site was numerous versions behind current.
