That depends on your operating system, your system, and your video card(s)...

In some cases you can't extend (split) the desktop between the screens but can only show the same image on both screens. (Fairly common in Laptops and also found in some two output video cards with DVI and VGA ports.)

Sharp doesn't even mention what chipset it uses so until you can play with this thing in person you aren't going to be able to figure this one out..

if you only see 1 in the display properties then right, it cannot perform the extended function, but like pcbonez said, all depends on your OS and vid card.

It's been a long time since I messed with it and I don't remember what laptop I was on but I do remember one where I could change between one and two monitors under that settings tab using the software provided to support the video card (chip) in the laptop. I 'think' it was an ATI video chip.
... But if you don't know what video chip is in the laptop I can't tell you where to look..

Dell has good support compared to the sharp but you need to enter some things that I dunno to get to the right drivers and DOCs..

It looks like the Dell has Intel 845GM based video which may support what you want t do.

Let's say the laptop can only support one montor (two identical screens), can not support extended screen, is there a way, say, some sort of connector to make it extended screen?thx
PCBONEZCommented:
I'm not sure what you are asking..

Mirror Mode: Two screens, same image.
Extended Desktop Mode: Desktop spread across two screens.

To get Mirror Mode with two external monitors all you need is a basic VGA Splitter.

To get Extended Desktop mode the video card (integrated in laptops) has to be built such that's effectively two parallel video cards -or- you must have two video cards.

If the one in your laptop is not that way, to get there you must add another video card.
In laptops this can be done with a PCMCIA or USB add-on video cards.
