We have come up with a list of common problems that will hopefully be able to help you trouble shoot the projector setup process. Before calling your AVDJ technician, please ensure you have tried some of these steps.

Is the projector set on the right input?

In most cases the projector will automatically switch to the right input to display your image as soon as a signal is present. If you have plugged your device into the projector and all you are seeing is a blue screen, try cycling through the inputs of the projector. Inputs can be changed / cycled by depressing the input button on the top of the projector, or depending on the model, by entering the projectors menu structure.

Using S-Video or Component inputs

When using S-Video or component you will need to manually set the projector for the corresponding inputs. This can be done by entering the projectors menu and selecting S-Video or Component input from the option list of the menu.

Laptop Settings

The number one problem when no image is being projected from the projector is actually laptop and laptop software settings. Projectors are much like TV’s, as soon as they receive a video signal they will display the signal.

If you are having trouble with your projector displaying an image, it is more than likely related to dual display settings of your laptop. As there are many different operating systems (both Mac and PC) all with different process’s to address dual display, it is not feasible to list instructions for all possible models and operating systems.

Refer to your laptops user manual or search Google for “multiple display” followed by your laptop model number and or manufacturer name.

Some laptops have a key that will cycle through the various display options available. These options can vary, but traditionally there are 3 main settings.

  1. Display Image on laptop screen only
  2. Display image on laptop and display same image on external connected monitor or projector
  3. Display main image on external monitor or projector and turn off laptop display.

Most laptops have a Display Key (sometimes accessible by pressing function and one of the “F” keys). The display key will have an icon of a monitor, or two rectangles, or a combination of rectangles inside of other rectangles.

If you are planning on viewing a movie, high definition video content, or high resolution images we recommend you chose option 3 with your laptops display settings. This will reduce the load on your hardware as the laptop’s graphics card will not have to render the image(s) on two different displays.

Power and or red light is on with no image and very loud fan noise

This problem can be caused due to a couple of things. Commonly, moving a projector during startup can cause it to shut down as a safety precaution. The second possibility is due to overheating.

If the Red light is flashing and you cannot get the projector to display an image or turn on, unplug the projector from the power source and leave it for 10-15 minutes too cool. The projector will start as normal after it has had time to cool down.

Image Upside Down or Reverse

All our projectors are tested and set to default settings after each hire. However, your image may be upside down or reverse as the last time it was used it may have been hung upside-down or used with a rear pro screen (which requires the image to be in reverse). If we somehow missed resetting the projector to its original default position, it is very easy to rectify.

Enter the Projector menu by depressing the menu button. Move to the icon that looks like:

Projector Reverse Menu

By changing these settings you can return the image to right way up or the right way round, or vice versa if you are planning on hanging one of our projectors.

Image not square? (Keystone)

Keystone is a feature that centralises the image to create a square display area within the projectors maximum display space. This is useful if the projector is at a lower angle than the screen or if the projector is needed to be slightly off centre to the screen. Depending on the model of your projector you will either have up, down, left and right keystone buttons on the top of the projector or you will be able to access the “keystone” feature in the projector menu. Adjusting the keystone will give you the option to create a square image inside the projection area should you need to.

How to get the best picture

To archive the best quality picture we recommend using VGA or DVI cables. VGA and or DVI (same as HDMI) signals are used in all laptops. If you are watching a movie, your image quality will be much better if done through a device with VGA/DVI or HDMI, such as a laptop or bluray player. The RCA cable from a standard DVD player, games console, and sky box will reduce the resolution and limit the potential image quality. Particularly for our HD and advanced projectors.

Can’t get my PS3 to work?

Sony PlayStation employs copy protection system for it PlayStaion consoles. This is a piracy protection to prevent direct copying of digital video content from its device. This is a necessary copyright protection for its devices and media. Unfortunately, it can prevent some PS3 models from displaying an image to a non HDMI or VGA projector. Despite all manner of adaptors and convertors used, if you are using one of our low to mid range projectors with a PS3, you will also need to hire one of our HD furry convertors. HD furry converts HDMI signal to VGA/DVI and splits the audio to a separate output. This allows for a PS3 to send a HD video signal to a VGA projector, and the audio to stereo, iPod dock, headphones etc.
