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.

How to Connect Laptop to Projector

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
Connecting computer and projector or TV
Display using Desktop
Display using Laptop
I don't see an image on my TV screen

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.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-1.jpg 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.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-2.jpg 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.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-3.jpg
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.
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.

Where is the projector connection on vaio fit


1

Insert one end of the VGA cable into your Sony Vaio. This is located on the left side of your computer.
2

Turn off the Infocus projector before connecting the opposite end of the VGA cable into the projector. The VGA input slot is located in the back of the projector.
3

Turn on the projector and allow time for it warm up.
4

Change the video output source on your computer to display through the projector. Press the "Windows" button and then "LCD/CRT" button on your Vaio keyboard to change the display source. On a Sony Vaio, the "LCD/CRT" button is usually "F7."
5

Focus the projector to most effectively display content from your computer. You can manually focus the projector or press the "Auto focus" button on the top of the projector.

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.

When I switch on the projector,VGA searching appears and I cannot remove it and consequently I am unable to project my DVD on the computer I have pressed re synch but it does not make any difference .


What input are you using and what is your input source? If you are using your computer as a source, you need to sync up output display resolution with projector resolution. Also check to make sure that you are outputting through VGA out on PC, particularly if it is laptop. You need to change display settings for dual or second monitor output.

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.

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


Hi,

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.
