I have a DELL desktop. I need to add a second display (bigger wall mounted monitor) to it.

Is there a way current video card provide display to both displays? Or I need to add another card? Is there any switch available?

Purpose of the 2nd display is to show images to people sitting a little far. So I was thinking 24" LCD. Do you guys recommend any PRODUCT (probably viewing angle is also a factor).

Thank you so much.What kind of SLOT do you have and what OS?

You might want to check thisout... What is your current video card?  Do you actually have a card or does your system use onboard/integrated video?  Does your current card have two ports, i.e. connectors, for video display DEVICES?   

Many cards have a VGA/D-SUB and a DVI port.  If you card only has one port, then you'll need to either replace your card with a card that will support two monitors or add a card to run the second monitor. 

What is your current video card?  What is the make and model of your COMPUTER or motherboard?Here is how know! Look at the back of your computer and if you have two spots to plug in monitors, then yes you can. Otherwise go out and buy you dual video card, they are easier to install and use in the long run.It is Dell Dimension 4700 desktop.

It has Intel GMA 900 controller.

This means I need to buy a dual output graphics card, right?

Thank you for help guys.hmm..

Dell Dimension4700. It uses on-board video, right?
