I have bought a new desktop computer and added an nvidia graphics card to run 2 monitors.

One monitor runs without a problem.

After inserting the DVI to VGA adapter and then plugging in the 2nd monitor nothing happend.

I use windows vista and all the help just say go to control panel - appearence and personalisation - adjust screen resolution / display settings from where you can activate the "number 2 monitor".

However Vista does not recognise there is another montior so there is no number 2 monitor in this section.

To add to this both screens work as I've had both running separately and since plugging in both of them at the same time Vista has switched to using the newly plugged in one.

I have switched off and on but nothing changes. Windows help website is useless. Now I think I understand Apple people when they say ...they just ..work.

Can anyone help me please????
