This may be caused by a power saving utility on the computer that disables the video output signal after a specified period of inactivity. Disable all power saving programs and screen savers on the computer to prevent signal interruption. Refer to the computer documentation to disable power saving utilities.

If you have disabled the computer power savers and screen savers, and the issue persists, it may be due to a setting in the projector. Some models include a power save feature, which turns off the lamp after no computer or video signal is detected for a certain period of time. To see if your model has this feature, see your user's guide.

This means that the projector and computer are running at two different resolutions. If an image is cropped, the computer resolution is set higher than that of the projector. If text is not sharp, the computer resolution is probably lower.

If possible, set the computer resolution to match the projector's native resolution. For example, if your projector has an SVGA resolution (800x600 pixels), your computer should also be set to 800x600 pixels. See What resolutions is the projector capable of displaying? for information about your model.

With some laptop computers, it is necessary to disable the laptop display to attain this resolution, especially when the native resolution of the laptop display is higher than the projector's native resolution. Most laptops require a function key or combination of key commands to disable/enable the laptop display. Check the Laptop Activation Chart for the appropriate command for your laptop make/model.

Additionally, in the Image menu on the projector, make sure that Resize is set to standard.

If these suggestions do not help, make sure that the projector’s firmware is updated to the latest version. See Firmware Updates on the main support page.

This happens when the laptop does not have the resources to display the DVD in two different places at the same time. To solve this issue, press and hold the FN key on the laptop, then press the appropriate function key (F1, F2, F3, etc.). The function key should be labeled “LCD/CRT” or will have a monitor icon on it. You may need to press the function key a couple times. When you do this, you cycle through three settings: the image only on the laptop, the image on both the laptop and projector, and the image only on the projector. You want to set it so the movie appears only on the screen.

To connect an InFocus projector to your laptop, use the M1-A cable that comes with the projector. The M1-A cable runs between the M1-DA port on the projector and the monitor port on the laptop. Some newer projectors and many older projectors do not have an M1 port. Check to see if there is a VGA connector on your projector. If there is, you can connect the projector and laptop with a VGA cable, which are available in most electronics stores. Finally, older InFocus projectors may use the CableWizard to connect to a computer or laptop. Refer to your user's guide for information about the CableWizard connections.

For illustrated guides on connecting your PC or Mac laptop to an InFocus projector, see Computer Connections in our How-To section.

To connect the projector to a desktop computer, you probably need to unplug the desktop monitor from the computer.

Most of our projectors require that you plug the M1-A cable into the projector's M1-DA port and the computer's monitor port. If your projector does not have an M1 port, you connect a VGA cable to the projector and the to computer's monitor port. 

If your computer's video card includes only one VGA port, you need to purchase a VGA distribution amplifier to connect and view your monitor and projector at the same time.  

If your video card has two VGA ports, you can connect the monitor to the first VGA port and the projector to the second.

For an illustrated guide on connecting your PC or Mac desktop to an InFocus projector, see Computer Connections in our How-To section.

InFocus projectors have a built in Universal Power Supply which automatically accommodates input voltages between 100VAC and 240VAC and frequencies between 50 Hz and 60 Hz. This will allow you to use the projector in any part of the world. But you will need the correct power cable or adapter. Visit the InFocus Accessories Store to purchase power cables for use in other countries.

When a projected image is wider at the top or the bottom, or taller on the right or left side, we say that the image is 'keystoned'. Keystoning happens when your projector is not perpendicular to the screen, either in the vertical plane or the horizontal plane.

See Keystoning - Making the image a perfect rectangle for more information. (458K, PDF, left click to open, right click to save)

Correcting vertical keystoning

If you use the elevator to tilt the front of the projector up so you can get the image higher on the wall, the image will suffer from vertical keystoning. Likewise, if you mount the projector on the ceiling and need to tilt it to get the image on the screen, you'll also get a keystoned image.

or  

1. Try raising or lowering the projector. You can correct for keystoning by making sure the projector is placed perpendicular to the viewing screen. For example, it may be necessary to place the unit on a higher surface to correct the image. Or you can add an extension to a ceiling mount that allows you to mount the projector lower.

   

2. Finally, change the Keystone setting on projectors that include this feature.  

   Press the Keystone + or Keystone – button on the remote control to digitally adjust the image. Use this method when you cannot solve the keystoning issue by changing the projector placement.

   You can also adjust keystone in the Display menu. To access the Display menu settings, press the Menu button. Go to Main > Picture > Keystone. Press the Up and Down arrows to adjust the image. The default setting is 50, which means there is no keystone adjustment.

   Please note that it is always better to achieve a rectangular image by moving the projector. Some images look much better when there is no digital keystone correction.

Correcting horizontal keystoning

If you place the projector so that the lens is not perpendicular to the screen in the horizontal plane, the image can suffer from horizontal keystoning.

If your image looks like the one above, slowly rotate the projector until the image is rectangular.

The computer refresh rate is either too high or too low for the projector to synchronize with. On the computer, go to Start>Control Panel>Display>Settings>Advanced>Adapter (This varies by operating system and by video card. See your computer/video card documentation for more information). If the adaptor allows you to select a profile, choose 1024x768, High Color, 75Hz for the LP130. You might also be able to change the refresh rate on the Monitor tab.

1. Make sure the logo screen (the screen where the InFocus logo appears) or the blank blue or white screen appears. If you don't see any image, check to make sure the lamp is lit. DO NOT STARE DIRECTLY INTO THE LENS--THE LAMP IS VERY BRIGHT! If the lamp isn't lit, see There is power to the unit and the fans are running, but no image is projected.

2. Press the Computer or Source button on the projector keypad or remote control. This forces the projector to look for other active sources. You may need to press it more than once.

3. Make sure all cables are securely seated. Make sure the cables are connected to the proper ports. One end of the computer cable should be plugged into the blue Computer In connector on the projector. The other end should be plugged into the Video port on your computer. Most likely, there will be only one VESA connector that will fit the cable on the computer.

4. Turn the projector on first, then the computer.

5. Make sure the computer is set to a compatible resolution for your model. See What resolutions is the projector capable of displaying? for more information.

6. If you're using a laptop and the computer image still does not display on the projector, try activating the computer's external video port with special keystrokes. Press and hold the FN key on the laptop and then press the appropriate function key (F1, F2, F3, etc.) that's marked LCD/CRT or marked with a picture of a monitor. (Refer to the laptop activation chart or your laptop documentation for further video port activation instructions.)

   You may need to press the Function key more than once. Many laptops cycle through a series of configurations at each key press, including image on the screen, but not on the laptop, image on both the screen and laptop, image on laptop only. Be sure to wait five seconds or so after pressing the function key. Sometimes it takes the projector a few seconds to communicate with the laptop.

Make sure that the refresh rate on your computer is set between 60 Hz and 75 Hz, or Adaptor Default. If you are using a laptop, always use AC power, not the battery.

This may be caused by a power saving utility on the computer that disables the video output signal after a specified period of inactivity. Disable all power saving programs and screen savers on the computer to prevent signal interruption. Refer to the computer documentation to disable power saving utilities.

1. Reset the projector to factory defaults. See your user's guide.

2. Change sources. Try plugging the projector into another computer.

3. If the color problem persists, check the cables for bent or broken pins. If any pins are damaged, the cable will need to be replaced with an InFocus-approved cable.

4. Upgrade the projector firmware. See Firmware Updates on the main support page.

5. If the projector still will not display the image, it is possible that there is an internal problem that requires repair. Take the projector to your dealer or contact InFocus Technical Support.

Note: Color adjustment settings in the Main > Picture menu works only with video sources, and does not apply to computer sources.
