dual monitors problem

Greeting, I have a small problem. I have my old AOC07 monitor (CRT), and brand new Acer 19" LCD wide screen. my video card is GeForce 6800 128MB. Here is my problem. I am trying to make my computer to recognize Plug and Play for a new monitor, and it happens nothing after I plugged in DVI cable. I open up Nvidia settings, and I am able to change a setting there for my 2 monitors. I selected Horizontal Span, and I clicked ok. another monitor came on. I understand horizontal and vertical spans.

I checked up Device Manager to check if there are 2 monitors there. it is. even there is no hardware found on the screen yet after plugging in a new monitor with DVI cable. I am so confused. All i need to add a new hardware for this new monitor to my computer.

also, if i restart my computer with 2 monitors on, they won't come on. i have to unplug DVI cable, and turn it again. one monitor came on with VGA. I want only my new LCD wide screen monitor for DVI cable.

so do you have any idea? I hope you guys understand this situation. thanks for listening to me for a few minutes :)

/bump again. please help. i do really want to understand my situation here with my computer
 
Have you tried the LCD by itself (i.e., only the DVI cable plugged into the card)? I wonder if it has an issue.

It's possible with "only" 128MB of vram that your card can't handle the spanned resolution. Try a very low resolution (along the lines of 640x480 - whatever that works out to spanned).
 
quite interesting. i plugged in the DVI cable with my new LCD only, and it won't turn on. Monitor did actually turn on, but it announced "No Signal." Something is up to my monitor, DVI cable, or my display card. So, kadiir, ya think my 128 AGP display card can't handle it? Could DVI port be bad? I never used it before until i got my LCD monitor.
 
Boot into Safe Mode - it forces the resolution to 640x480 at Windows startup. If that doesn't work, it's not an issue with too little vram or the card not handling the resolution.

Have you tried a different DVI cable? I was reading over in the Benq FP241W thread about how the Benq cable is a skinny POS. One guy couldn't get proper signals with an 8800GTX. He got a nice, thick cable and everything worked fine.

If you want to go that route, that guy bought one from monoprice.com - they have very good prices. A 6 foot 24 AWG cable is only $11.48 USD, for example.
