Will not regonize computer source


The projector looks for Horizontal sync & Vertical sync signals from the VGA source. If it finds these signals only then the source is connected. Even if the sync signals are found, the RGB switching should be working. Either there is a problem in sync circuitry or RGB switching. You need to be well conversant with the circuitry.

Why does my projection look green if the colors are right on the computer?


I'm going to guess that you are using an RGB cable to connect to the projector and the projector is expecting a composite signal. The composite signal would be what uses a yellow connector when you use hte red/whjite/yellow type of cable. All of the video is carried by the yellow. If the projector is expecting this and you send out component (RBG in this case), then the only video signal processed is the green. Since the green also contains the sync signal, the picture will be seen but green.

Check the menus on the projector. You should find a video selection area that will allow you to change to component input.

Please update this if you have any more questions.

I have a dataprojector, no signal


Then 'No signal' or 'unsupported signal' messages are usually because your display is set too high. To see if this is your issue, hoop it back up too your computer & set the computer to the basic VGA resolution. Assuming you are using windows, 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, then 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.


Note for Laptop users-- 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 <fn> button (on the lower left of the keyboard, usually to the left of control <crtl>) and tap the bleu button you just found. Let go & give you

No input signal form a laptop to a projector


Hi jkoceng,

What type of interface cable are you using to connect to the projector? 15-pin VGA? S-video?

Generally on laptops if you look at the keyboard on the function keys (F1, F2, etc.) you'll see little icons such as adjustment of volume, brightness, etc. Look for one that looks like a monitor or screen. Usually this is on the F5 or F6 key. If the icon is blue, look for the corresponding key on the keyboard (Fn key, CTRL, Alt, etc.) and then hold that when connected to the projector while you press the appropriate function key. This should alleviate your problem.

Of course, you'll also want to be certain that you're using the correct input function on the projector.

No signal for my lcd projector


You have to "Toggle" your PC to output the signal to the projector.

On which "F" key do you see "CRT/LCD" or a pictute that looks like a monitor?
