Can't answer for the menu issues, but I can garuntee this is not a problem with brightness, contrast or sharpness, and very unlikely that you'll find a solution in the menu. What is likely is that the VGA wasn't plugged in properly initially. When the signal is going down the VGA it's broken up into 5 seperate signals, Red, Green, Blue and 2 sync signals. What is likely is that the green and blue pins havn't properly made contact either inside the projector or inside the laptop. This would also explain why it worked when you tried later because it made the connection properly. I would suggest trying again with the same laptop, if it does it again, try another PC without moving the projector or the VGA connector that's plugged into the projector. This will atleast narrow down your problem, but it doesn't sound like a problem with the projector to me. Also try plugging the laptop that wasn't working properly into a monitor (this will test the laptop)
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.
Unfortunately, there is no simple VGA-to-RCA adapter cable if you're connecting to a composite video input (usually colored yellow) or s-video input. VGA output is separate red, green and blue video and synchronizing signals, and they all need to be combined. You need a VGA-to-video converter to do this.
If the projector has component video input jacks, then you can buy a simple adapter cable.
If you're using component video (red/green/blue rca cables) one of the colors may be disconnected, or the wires may be swapped into the wrong color input. If you are using a 15 pin VGA connector, one of the pins may not be getting good contact at the source or at the projector. Or if the VGA cable is split into 5-wire to make a long cable run, one of the five wires may be disconnected. Any of these problems will cause a global color shift while not affecting the color of the projector's on screen menus.
try to use another vga cable connector ther might be a cut on the red color signal try to move the connector form left to right until it gives you the red color if it does change your vga connector hope this help you on your problem thanks
