I actually have two Acer laptops in our school district that seemed to have lost their VGA connectivity (the projector works fine with other systems). When connected to the laptop the projector just displays a blue screen. Any thoughts?
Here is the deal. Right-click on desktop. Choose settings. Right-click on screen #2. Click on apply for new settings. The one additional problem you may encounter is the fact that the projector will display an area to the right of your laptop screen. In other words, move your mouse past the right edge on laptop screen. Look at projector image. See your mouse?

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.
If your tablet has a VGA connection which I doubt, you'd just connect the two devices with a VGA Cable. Otherwise you'll need some type of adapter to go between the two devices to make them communicate. Good Luck!!! If you had purchased a normal laptop, you'd have a VGA connection.
The following is from page 69 of the 354-page Dell Technology Guide for the N5010
General Keyboard Shortcuts
Displays icons representing all currently available display options (display only, external monitor or projector only, both display and projector, and so on). Highlight the desired icon to switch the display to that option
So the solution is just plug the VGA cable from the projector into the N5010 laptop's VGA port and then press <Fn><F8> (Function and F8 keys together).
The Acer One netbook has a mini-VGA port on its left side. Page 10 of Acer's QuickGuide shows the port as item 3 External display (VGA) port. But unfortunately, the description shown for it is incorrect.
From your description, your projector's lead likely has a mini-VGA connector on the end as pictured. The connector can simply be plugged into the mini-VGA port but there are no holes beside the port for screws so it would just be a friction fit which should be sufficiently secure for most puposes. The connector and port are mini-DB 15 male and female respectively and can only fit one-way. The port has the wide side of the D on top so you would have to turn the pictured connector over to be able to plug it into the port. Windows XP should be able to detect the projector via plug-and-play installing any display drivers if required. Page 8 of Acer's UserGuide describes Hotkey + Display toggle which switches display output between the display screen, external monitor (if connected) and both. Pressing + with the projector plugged in will bring up a window in the middle of the screen allowing the selection of internal display, external display, both, or a 800x600 VGA projector. If the display is on the projector, unplugging the cable should automatically revert display back to the internal screen. For VGA see http://en.wikipedia.org/wiki/VGA_connector
The Aspire One has an external VGA port so you will use that and a VGA cable to connect to the projector. You may have to press the Display mode button (typically Fn+one of the function keys with the rectangle 'display' on it) to enable the external VGA port.
just connect the vga cable to vga port of laptop and to the projector and in projector choose the source of display vga or pc mode and in laptop press f5 button or right click on desktop and choose the display mode lcd +monitor it will show you the display on projector. Have a nice day and do not forget to rate please...!
