Laptop connected to projector get initial message "no signal" then projector continually searches through video, computer 1 and computer 2 - what do I do?

disconnect the cable at the projector end and plug into a monitor to check that the video signal is enabled on the cable. If it is then reconnect to the projector and select a lower resolution on the pc screen setting. See if anything appears on the projector

'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 :)

disconnect cable from the projector end. Then connect the free end of the cable to an LCD monitor to confirm that the video is coming out the laptop and out the same cable.

Then reconnect the projector.
press the source button until the video appears

I am not familiar with your Hitachi LCD projector . However , I do have a little knowledge regarding video signals and inputs / outputs as well as connections . If your connecting cable is one piece (has no adapters added to either end of it ) I would believe your problem is simply a settings misconfiguration in your projector / computer , or both . First , access your startup BIOS / CMOS settings during the initial booting sequence in your computer by pressing F1 or whichever keys you press when you turn the computer on to access it . Then , in the advanced list , check your primary video input selection to be sure it is default. Then, once the computer is completely booted and you can click on your start selection , go to your video settings and check how to switch between internal and external display options . I say this because it is important that you are able to reroute your video signal to your SVGA Out from the laptop (for sure) and it is in fact in that video output mode. Once you're sure you have a signal going out of laptop through that port , go to your projector video input selections menu and select each and every input option available until the signal comes through . This will only work if you're absolutely 100% sure that your video signal is in fact leaving the laptop via the SVGA port connection .

If you are connecting to a laptop then you may need to hold the function button down and press F1, F2, F3 etc. there should be a sign with the latop on there and a sign with an external device (monitor,PROJECOR)
hope this information was useful to you.

Once the projector is connected to your laptop, and both devices are powered on, press the Fn + F8 keys on your laptop to toggle your screen to the projector.

1.
Connect the external display port on your laptop computer to the projection system, and then turn on the projector. For information about connecting external devices to your laptop, see the documentation for your laptop computer.
1.
Set the display resolution of your laptop computer to match the resolution of the projector system. First, on your laptop, open the Display Properties dialog box by using the Display icon in Control Panel, and click the Settings tab. Then, in Screen resolution area, move the slider to adjust the display resolution of your laptop. If you don't know which setting to choose, try 800 x 600 pixels; this is a common setting for many projector systems. YOURS sounds like 640x840.
3.
If you have audio in your presentation, connect a cable from your laptop's audio output jack to the audio input jack on the projector, and then test the volume by playing a file that contains sound.
4.
Start the Player on your laptop. If you want to only display the Player on the big screen, and not the desktop background, maximize the Player or set it to play your video using the entire screen (full-screen mode).

Hi and welcome to FixYa,

Initially, the "No Signal" error message indicates just that, it is not receiving anything or that the signal it receives is beyond its capacity. With this in mind, pls check:

• the cable connection from PC to Projector;
• that the PC is set to display on a 2nd monitor, TV or Projector depending on the capability of the PC's video card (Twin View or Dual View); or
• as main monitor;
• lower down the computer's Screen Resolution and/or Screen refresh rate.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Hello,

1.Go to the Properties by right clicking and go to setting, go to resolution 800x600 and then try again.

2. Connect Projector, Restart computer and connecting Rgb Cable.

Usually means that the computer is not sending a signal out the the projector via the monitor cable. Most Windows based laptop computers allow you to connect to a second monitor by pressing the Fn + F7 or F8 key, once to allow just the projector, twice to allow both the projector and laptop screen and three times back to only the laptop.
