How to display computer image on TV or projector
How to display a computer image on a TV or projector All modern televisions and projectors have one or more ports which allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables. The following sections contain instructions for using your TV or projector as a computer monitor. For best results, we recommend reading them in order.

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.




HDMI
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.


VGA
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.

DVI
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.



Composite Video
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.
S-Video
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.

Desktop Computers 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.

1. Press the Windows Key.
2. Type Adjust screen resolution and press Enter.
3. Find Display and click the down arrow on the right-hand side of the box.
4. Select the appropriate output device.
5. Click Apply then OK.

Laptop Computers 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.

• Steps in connecting an external monitor or projector to your laptop.

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.

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:

Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.

Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

Look for the F-key with a square/icon of a laptop. Press FN+This button until you see your screen display show that it will be using your LCD + the output on your computer. Remember you need to hook both the VGA or HDMI out to the projecter as well as the USB cable.

I am going to bet you got a manual with the TT-02rx that explains the connectivity. If not, you can go to www.elmousa.com and download the manual from the TT-02rx page. Look on page 30.

TT-02rx can be connected in a couple of ways:

1. Directly to Projector - connect a standard VGA cable from the RGB output on the TT-02rx to a RGB (VGA) input on your projector. This will allow you to directly display anything you put under the Elmo camera.
2. USB to laptop, VGA from laptop to your projector. You can connect a standard USB cable from the Elmo to an open USB port on your laptop. From the laptop, you will need to connect VGA cable from output jack to projector input. To view images from the Elmo, you need to have installed the Imagemate software on your laptop first. Elmo can only be viewed thru the software interface.
3. The last option is run VGA from your laptop to VGA input on the Elmo. Then run VGA from Elmo to your projector. This offers the greatest amount of versatility as you can switch between the image on your computer screen and the image on the doc camera. Adding the USB cable as described in 2 above will also allow you to use the digital features such as image capture, reveal, spotlight, etc.

If your projector displays no image, this could be a variety of problems. First, check that the projector has power. On the top of the LCD or DLP projector should be some lights. With power, those lights will be on. If it has power, check to make sure that the projector lamp is firing. If so, go to the source. Make sure that it is connected with a VGA cable or USB cable to your computer, or with an RGB cable, S-Video cable or DVI connection to your VCR/DVD Player. From a laptop computer, the VGA cable should be connected to the VGA out connection, and into the VGA in connection on the projector. Are both ends tight?
If everything has checked out so far, the solution probably lies with the external monitor port. Check this by holding the Fn key on the keyboard, then press the F7 key. (On some computers, the key might be F5 or F3. Try these if F7 doesn't work) Each time you press the Fn / F7 combination, you will cycle your display through the following settings:
* Press Fn / F2 or F2 once: The laptop screen only
* Press Fn / F2 or F2 twice: The projector port only
* Press Fn / F7 or F2 three times: Both the laptop and projector port
* Wait a few seconds after each time you press the key combination to let the LCD or DLP projector refresh. Nine times out of ten this will result in seeing your projected image.
this should help you :)

Hope this helpout....

computer should always be connected with 15 pin VGA to DVI-I cable.
Select in menu input 1 analog RGB and adjust output resolution of Dell to 1024 x 768. this should work !
USB is only for mouse control with pj remote

Reconnect the cables and press Fn+F8. Restart your projector and your laptop Your external projector should show video from your computer.

Usually you can use a VGA connection cable to connect your computer with a projector. They also have inputs for s-video and RGB but these are much rarer on computers. Once you have connected the projector press the key on your keyboard that looks like a square with two lines on either side (mine is FN+F4) This will shuffle through different setups (mirrored to screen, extended to screen and back to normal) if this doesn't work try plugging in the vga cable and restarting the computer with the projector on.

Hi-

Check the ports from the back of your projector, look for an s-video port then check the available ports as well on your computer, so you either use an S-video cable or VGA cable, then when you connect your computer, if its a laptop press fn key then double tap f5 or f7.

keep me posted
