Re: Laptop computer connected to projector.
When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.
But once you find your dual display options you will be able to change it to make both displays the same

Identifying available connections
The first step in connecting your computer to a TV or projector is finding an identical port on both machines. Once the matching port has been identified (one that is the same on both your input device and output device), you need the appropriate cable to connect them. This section contains a picture of the back of an Epson projector and its available connection ports; as well as descriptions of each.
The HDMI connection is very popular among display electronics. In fact, nearly all modern televisions and projectors feature HDMI ports. Most laptop computers support HDMI and it is becoming more prevalent on both desktop as well; even without a high-end video card. HDMI is quickly becoming the standard for all electronic equipment for its high quality signal and ability to carry both audio and video signals. The image to the right is that of an HDMI cable.
The VGA connection is the most common among both desktop and laptop computers, is found on most projectors, and some TVs. The VGA cable has a 15-pin connector on each end that plugs into a VGA port on each device. Due to the fact that most televisions do not support VGA, we recommend using HDMI for their wider range of compatibility.
Tip:VGA cabling is universal for devices that support it. For example, the if your desktop monitor that uses a VGA cable it, that same cable can be used by a laptop to connect it to a projector.
Note: If you are using an Apple desktop or laptop you need a VGA adapter to connect a VGA cable to the computer.
The DVI connection is newer than VGA and it offers a sharper image. Although the DVI port is not shown on the Epson model above, it is still somewhat common for projectors, not so much for televisions. It is mostly found among desktop computers for monitors, but some laptops have DVI connections as well (Apple laptops are more commonly known to support DVI than any other brand of laptop). Since finding DVI on a TV or projector is more difficult, we again recommend using HDMI cables.
Tip: There are special cables that convert from DVI to VGA or DVI to HDMI and vice versa.
The composite video connection is quite common on a TV or projector, but it is nearly nonexistent on modern computers. This connection is the yellow female cable on what is normally a three bundle of red, white, and yellow. The only time you should see this setup is on older video cards for desktop computers.
The S-Video connection is also commonly found on TVs and projectors, but solemnly on a desktop or laptop computer. This connection is a small step up from composite video, but is nearing obsolescence.
Connecting computer and projector or TV
After you've identified what connections are available on both your computer and TV or projector, you're ready to connect the cables. If the same connections are not available for both the computer and TV or projector, you'll need to purchase a video converter cable that converts one signal into a compatible signal.
For a desktop, you simply need to plug the cable into the computer and output device. If you don't see an image, you may need to change the display using the following steps.
Press the Windows Key.
Type Adjust screen resolution and press Enter.
Find Display and click the down arrow on the right-hand side of the box.
If you're connecting a laptop computer to a TV or a projector you'll often need to "send" the video signal to the display device. The key sequence to do this varies depending on the laptop; but usually it's either: Fn + F3, F4, F5, F8, or F9. For example, pressing and holding Fn + F3 at the same time on my laptop sends the video signal to my connected TV instead of the laptop's screen. The corresponding key used with Fn may be labeled as CRT/LCD or have a picture of a monitor on or close to the key. Additional help and information with switching the laptop display can also be found on the link below.
Switching TV inputs
Finally, if you're connecting a computer to a TV make sure it has been switched to the correct input. For example, if you connected an HDMI cable to your computer and the "HDMI 2" port on your TV, you'll need to switch to the "HDMI 2" input. This action can be accomplished by pressing the input button on your TV remote until the correct image is displayed.
Disconnect the cable that is connecting the laptop to the projector. Sometimes this will happen if the projector or device you're connecting your laptop to does not support the current resolution that the laptop is displaying. Reconnect the cable and try using Function F4. If that does not work then disconnect the cable from laptop to projector, reboot the laptop then repeat connecting it to the projector and pressing Function F4.
May need to hit Function+F8. This is Dell's standard button for pushing video out different sources, such as the VGA / DVI connectors in the back of your machine. You may also want to start with a "standard" screen resolution, such as 1280x1024 to make sure the projector can handle it.
Hold down the Fn button and press F8. Try this pushing F8 once. then try it again pushing F8 twice. And so on. The F8 button switches the display between the lcd monitor on the laptop and the external display. There should be an option in there to display on both at once.
Try to hit the Fn+F8 button at the same time 5 or 6 times. This is what is used to turn off your LCD to plug it to a projector or to use a different screen. If that does not work then try to find a desktop monitor and plug it into the 9-pin slot on your laptop. Again hit the FN+F8 buttons again, if the display shows up on the desktop screen then you know that something has burnt out your LCD screen on your laptop.
Ok.I got your point.Actually you're in extended mode.
Once you connect you can have 2 types of output to your projector.
1.Clone mode--> make everthing look the same
2.Extended mode--> have another new space for you to use.
** in extended mode you'll have a background of your desktop.you can drag any running program to that space.
How to setup clone and extended mode
1.Click start-->Settings-->Conteol Panel-->Display
2.Under Display Properties window click the last tab name settings
3.Under display select you 2nd monitor
3.Below Screen Resolution you should be able to see a checkbox "extended my windows destop on to this monitor"
please check this box for extended mode or uncheck it incase you won't to use clone mode.
