Our club owns a Canon LV-7240 which has worked OK. Last night we showed an NTSC DVD from Europe and no red showed. We could see what the colours ought to be on the laptop screen. On the big screen,...

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)

Welcome to Fixya. You need to put the file on the projector for you to view the PPT presentation.

You need to connect a USB cable shown on the image below. If you don't have the cable i suggest you purchase on just bring the projector to a store to have a compatible usb cable.

I my projector is new one used for 4 hrs, when i try to turn it on it just has a blinking green light. Please help Solve It! .

The blinking green light means the unit is either Powering On (Warming Up) or Powering Off (Cooling Down).

Powering On the Projector
1. Remove the lens cap.
2. Securely connect the power cord and signal cable. When connected, the ON/STANDBY LED will turn Amber.
3. Turn on the lamp by pressing " " button either on the top of the projector or on the remote. The ON/STANDBY LED will now turn Green. The startup screen will display in approximately 10 seconds. The first time you use the projector, you can select your preferred language from quick menu after the startup screen displays.
4. Turn on and connect the source that you want to display on the screen (computer, notebook, video player, etc). The projector will detect the source automatically. If not, push menu button and go to "SETUP". Make sure that the "Source Lock" has been set to "Off". If you connect multiple sources at the same time, press the "SOURCE" button on the control panel or direct source keys on the remote control to switch between inputs.

If you are still unable to get the unit to turn on, try unplugging it for 10 minutes and plugging it back in. If it still ceases to work, contact Optoma here:

It is probably mirroring the screens on your MacBook and the projector. If you want different resolutions and things on each screen, go to the Apple menu, System Preferences, Displays, Arrangement and uncheck the "Mirror Displays" checkbox.

Power Point Presentation Using Sanyo Pro Xtra X Multiverse Projector

Don't forget to select the Fn key and F4 on HP laptops. It could also be the Fn key and F8 depending on the laptop brand. It is the apple key and the F7 key on a Mac notebook. On Laptops this will toggle the video to the aux port where the monitor cable connects to the projector. There are 3 modes. video on the laptop screen, video on the laptop and projector, or video to the projector only.

Vertical control of viewing frame needs adjustment.

Did you try going into MENU --> PICTURE --> SIGNAL MODE, and then pressing > to go through all the signal modes? On mine, most of the signal modes split the screen weirdly as you described, but one of them (in my case XGA3, but I'm not using a Mac) looks right.
