My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:

Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.

Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

Try lowering your laptop's screen resolution and refresh rates to the lowest possible.

Additionally, you need to press Fn + F? keys on the laptop to cycle on laptop display, laptop display + external; display, external display.

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

Good luck and kind regards.

Hey my InFocus LP530 wont detect my pc/laptop, ive changed the auto sorce select to on but still nothing, so i changed it to off and tried all sorces manually but still nothing, Any ideas?

set the pc screen resolution to a low setting.
connect the vga output on the pc to an external monitor and check that the video appears on the external monitor. change the mode of operation on the pc until it does appear.
then disconnect the external monitor at the end of the vga cable, and connect the free cable end to the projector and auto source search for the vga input signal

No external projector found

make sure you the projector is set to the same port you are plugged into. are you just using it as a monitor or do you want to use the computer for projector control? because you can't.

Projector does not display laptop screen

Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the projector checks first for active video during power-up. Highlight Default Source and click the left or right mouse button to toggle
among the options.

No picture

You may need to reduce the resolution on your comptuer screen. Try going to Control Panel, Display, and Settings and lowering the resolution a notch or two.
Also, you must make sure that the computer is set to send the signal to the external monitor,. That usually means holding down the Function key and pressing the F5 key or the one with the picture of two monitors on it. You will see several options for display. Toggle with the F5 key to the one that shows the computer screen and the external monitor at the same time.
