I tried to set up dual clones monitors and set the display too high for either monitor now i cant see to reset the video display. Is there a way to reset the card to factory setting with seeing the monitor?

first ..for to work make sure you have the ge force driver installed for the video card ..and not just the automatically installed one from the windows..
than connect the monitor in the vga out for secondary monitor ..and get to the video card control panel ..in the windows control panel ..and enable the second monitor ..and set it as clone ..or in dual mode..which will not place the icons on it ..but will be an extension ..
This can be set and enabled also if you run the nvidia desktop manager from the control panel ..and set it clone ..if you want the same thing displayed in the same time ..or extended to the second one..(dual ) which will have some options ..
For the dual mode the good thing is that you can run separate applications in monitors..by opening them and drag them to the other monitor ..it will act like and extension of yours..
If you go to desktop properties.by click right on desktop ..and choose properties..than settings ..and in there monitor ..you can actually identify them and drag them to switch places to correspond to the actually position ..and after that the mouse will naturally get from one to the other if you point to ..
The normal behavior will be that once a aplication opened and dragged to the second monitor ..when you make it ful screen should extend only in that one ..but some players will make trouble and only will get to full screen in the primary one ..To avoid that use the latest free BS player ..

you can try to set it up ....get the video signal from the sec monitor out ..of the laptop ...and see the options into the desktop ...maybe it will work ...I dont see other way to get it ..but like a video input...the way you attach an auxiliary dvd player or something .and use the signal into the feature you have for clone monitor..in the desktop ...I never tried but it kinda seam logic ..its just a video signal ..and it has to be able to capture and see it ...but remember I dont really thing you will be able to interfere into it but just see it ..the handling will be made from the laptop's controls

have you tried the monitor on another PC? if yes? did it work? if yes, your new computer is set on a very high resolution that the syncmaster could not adjust...

plug your LG display into the DVI port and the BENQ into the VGA? it may just be a random compatability error.

the problem is not the monitor.To be able to correctly set a dual display mode you need to configure you video card to do so. This is accomplished in your video card's control panel. There are various modes:
Clone: it simply clone the screen you'll have the same output on both monitors.
Extend: this will extend your desktop and make it one big screen.
theres another mode to show video only on one screen while the other display regular desktop activities you'll have to experiment.
the procedures for doing this varies depending on you video card: ati, nvidia, or Intel.

Check and see if your NVIDIA drivers are up to date. Then try changing the resolution on your laptop to match the native resolution on the monitor and see if it works. If it does then you will need to look for the option to set custom resolutions on each monitor so that you can have both devices working at diferent resolutions if 1 is wide screen and the other is not.

Let me know if this does not work and you need more help.

Yes. You can set it to dual monitor or to clone mode whereas you will have the same picture on both monitors.

Here is a little guide for setting up dual monitors with fedora core 6: http://blog.taragana.com/index.php/archive/how-to-setup-dual-monitors-on-linux-fedora-core/

I haven't had to use duals monitors with Linux yet but if this doesn't work let me know and I'll run some tests as I can easily set this up at work (we use the same computers and similar cards).

Assuming that you have Audio already functional, the solution is to set your system to "Clone" rather than "Extend" video. Right click on desktop > properties > settings > click on second monitor > uncheck extend monitor box (below). Click ok, press Fn + F8 to Clone.

The problem is you may not have the correct hardware for dualview monitors.

You may need to change your display adaptor to one that supports dual view. Here is a link that contains a list of display adaptors that support dualview in Windows XP.
