I can't get marry my laptop to the projector the manual is lost. had to buy new usb cord and still can't get the projector to play my video

The USB connection only allows the projector's remote control to be used as a "mouse" to advance presentation slides on the PC and perform some other limited functions. The USB connection cannot be used to feed video or other signals to the projector. Refer to the operation manual here:
HP mp3220 series User Manual

I tend to use the VGA cable. Once connected, switch the laptop on until you get to the desktop, then switch on the projector. Some will see the signal, if not, simoultaneously press your FN and relevant 'F' key to send the signal out to the VGA. You may need to do this 3 times, once to send to projector, one to send back to laptop screen and then once to send the signal to both projector and laptop screen. Sometimes this can take a short amount of time. You may want to change the projector settings to the VGA input so it doesn't constantly search for a source. If you still have problems, go into properties on your laptop and advanced. you m,ay need to unclick the box saying 'Extend to..........' (You should find what I mean from this, I am in front of a pc therefore the settings are slightly different.)

If nothing then works, it may be your video card.

Good luck

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.

sorry dude the usb is for charging only you need to buy a vga to composite cable and a male to male component cord both purchaseable from this web site http://www.bestofferbuy.com

laptop, vga. dvd, composite or s-video, and audio. gaming console, composite or hdmi, if you have it.

The USB cable doesn't transmit Video. You need to plug in the VGA cable. The "DVI" port on the LP820 is not a a DVI but a M1 Digital port and won't work with DVI unless you get a converter.

Are you using dualview (cloneview)? Try just the single view, projector only. If that doesn't work, reboot with the projector cord plugged in. A similar problem happenned to me before and that's what I did to resolve it.

Hi John

Is your Projector's source scan swithed on ?

Does it pick up a signal when you press the source button ?

those weird names are types of video, you want that on auto...you need to set your display to detect another monitor or lower your resolution settings as well as your refresh settings (hertz) on your laptop

My projector will not show the picture but i have sound
