-toggle the laptop display using the FN keys and F5 I believe. -lower laptop resolution to 800 x 600 -look in laptop display properties for lcd or external display settings, see if it (external crt) has to be enabled on the laptop first.

SOURCE: Connecting a Optoma Projector to a Toshiba Laptop

I bought mine new... hooked it up and got the same response. I would have torn my hair out but I am bald! Checked everything. Great frustration. Finally, I thought to replace the cable with one I have on my monitor. Worked perfectly! A brand new cable and it was faulty! Contacted the company and they sent out a new one. Even sent a packet to ship my bad one back so they could find out what happened. No connection problems with the new cable.

SOURCE: Optoma H56 - turns off just after start up.

You have a blown bulb. I have the same projector and it had the same problem. The bulb is blown replace it and you should be fine.

If you are not sure of my solution you need to know that your projector will look like it is starting up and the bulb will partially light up but never come up to full brightness, then the projector will shut down. This will happen over and over until it just gets to the point it just turns on (the fan comes on and then about 30 - 60 seconds later the fan turns off.

Replace the bulb and you should be fine.

Been there done that!

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

SOURCE: My optoma projector does not find my HP laptop


What type of cable are you using to connect the projector to your laptop? if VGA you have ti press "FN" and F5 or the F key that has a monitor symbol on it. Try using a different cable as well and if it has an auto search button on the projector try pressing it.
Hope this helps

Continuously searching for input. have changed both vga boxes and cables.

I would go into the menu of the projector and turn off the auto source search function and set it to the VGA input. If you have tried your FN and 'F' keys simultaneously to send the signal through the VGA port and still have nothing, you may have a faulty video card.

Good luck, hope I was of help

The projector is not showing a dell computer

Turn off the computer.

Ensure that the projector is connected to the computer and turned on.

Boot the computer.

There is a very good chance that you will now see an image as expected on screen.

If this doesn't work, you may need to manually enable the external VGA output of the computer.

Asuming this is a laptop, Look for the key near the boorom left of the keyboard labelled "Fn". On the top row of "F" keys you will see associated icons and lettering in the same colour. Look for one which says "LCD" or "CRT" or has an icon which may represent a monitor.

Holding down the Fn key, press the top row key whoch you have just lcoated and hold it for approx 0.5 second. Wait 5 seconds. If nothing happens, press it again. On most computers this will cycle through available monitors options which include in various combinations local screen on, local screen off, external screen on and external screen off.

If there is no cycling of screen on/off there is most likely a problem with the computers display drivers.

At teh projector, make sure that you can cycle through all available inputs. There should be an onscreen display to indicate which input is selected. This should correspond to the projector input on the body of the projector to which the computer is connected.

If this doesn't solve the problem, you should try changing the VGA (or DVI) cable as it may have a broken pin or other fault.

I've connected my laptop to the projector. It displays the image for a second and then displays 'Analog RGB searching'

Try setting the projector to VGA instead of RGB input if you can, you should be able to toggle though input modes.

Make sure that the resolution of the laptop is equal or lower to that of the projector.

Connected VGA cable to my pc and projector.Searching only

First off be sure that you plug into the input connector. As you look at the back of the projector it the VGA connector on the left. Also make sure you activate the VGA output of you computer (This mainly applies to laptops and secondary Video jacks on PCs).

Not with any RGB input options, computers are not compatible with these. The projector needs to be set up to receive VGA. There must be a toggle button or menu entry somewhere on your projector that lets you do this or why would it have a VGA input?

Projector can't connect to laptop

We just solved a similar issue. Most likely your PC or laptop is currently set to a display resolution that is too high for the projector or is one that it cannot handle. Try setting your computer display to 640 x 480 or 800 x 600 and see if you can get the projector to work. If it does, then you can figure out the maximum display resolution you can use. Also consult your projector documentation for supported resolution modes.

For the PICO in particular, it looks like those are in general for small mobile devices (320 x 240 or less displays), and the PK102 model has native VGA (640 x 480) support with extended support for 800 x 600. You will not be able to use this on most modern computers except at the lowest resolution setting for the PC.

Connecting Projector to High Def Source (e.g. PS3 HDMI)

That projector supports M1-D also which is the digital side of the M1-DA... Anyway, they sell cables that are M1-D to HDMI to which you can hook directly to the PS3. They are decently priced too, less than $20. I know this thread is old, but I came across it due to an issue I am having with my xb31, broken color wheel. Trying to find parts...

Connecting Ibook G4 to Sanyo PRO xtrax projector


Most of the Apple iBook G4 series have a video out port on the left side. This is a non-standard port and would require the use of an adapter (Apple VGA Display Adapter) that is normally included with the laptop package when first bought. The VGA's output connector is the standard 15 pin HD D-Sub (HD-15).

On the other hand, the Sanyo PRO XTRAX projector is capable of multiple input type of connectors. They are: a) RCA type composite video in, b) DVI, c) RGB, c) RS232, d) S-Video, e) USb and f) VGA. You would then be using the latter, VGA since it matches the Apple VGA Display Adapter.

To connect the iBook to the projector, you would need a length of VGA cable that are available in most projector/computer stores. Here, here and here are examples of commercially available.

Please refer to the images below.c02d50f.jpg

Hope this be of some help/idea. Pls post back how things turned up or should you be in need of additional information.

Good luck and kind regards.
