Sometimes it helps to hook up laptop and then power everything up at once. Also check and make sure that you have the source looking for the laptop or have it on auto search for it may also need to the check the menu for the projector to see if the may have a manuel connect for the laptop to be able to view

Compaq 3800 projector.I have a Carbon X1 Thinkpad . I bought 3 different cables already,it can not find the source.Fn-F4 nothing-Lower resolution nothing.If somebody has an answer please shoot

wow what a complex post.
why not tell a story, use notepad, and type it and paste it here so we can see whats UP?
what are you attempting, seems the Projector is dead, right>
what cable, did you use a short direct VGA cable.
is it VGA> seems yes, you said, Fn-F4 so is VGA
my guess is its custom long cable you made bought or?
what does this line mean.???
With my Desktop is not problem!

i can not understand any of this , and ive run projectors 100s even 1000s of feet, in airports and other huge , venues.

my guess is you do not understand video and its limits.
you can not send high resolution to a old projector
and windows 10 does not run low reso. unless force
windows 10 does not run old obsolete displaces or chips at all.
now.. they are obsolete... i can list 1000s dead now... can.
The DLP projector is a very cool thing,Texas Instruments based magic.
but is old and has 1024 x 768 native resolution
so to get that to work with XP,.W7, W8 or W10
the latter is most hard, as W10 does not work and low reso.
(means not automatically work)
you have to force it.
(btw, in say xp/w7 go to safe mode F8 and force low reso.)

to do that SAY< in w10, you'd rigth click your desktop screen
go to settings then advanced display settings
click screen pick display setting, at bottom of that screen pick advance settings.
then pick above reso.
i just did and screen goes SQUARE 4:5 mode.
ugly by todays standards.
not plug in the projector and press Fn +F4 bingo, out it goes.
keep in mind some GPU chips many not allow this.
id need to know each chip in each machine used to answer that.
if the projector fails now, then try a regulor desktop monintor now
at the PC under test VGA port does it doe above reso.
yes then the projector has issues.
all this done with short 3'ft standard VGA cable as see on back of
all VGA monitors use that to test and get that work ing before using wild custom cables, unstated by you...
but youve posted before on this setup, have you not.

Cannot find the source


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.

USB is only for mouse control with pj remote

The projector can't find the source, which is my laptop. If it does find it, it lasts one, maybe two seconds, and then it's lost it. We've tried two different laptops, and it cannot hold the connection for...

Maybe the cable connected to the projector is bad?

If you shut down the laptop and plug the projector in on 'PC' mode, does the projector recognise the video output?

Delay/ whitescreen when projecting video from laptop

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.
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.
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.
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).

Won't project; can't find signal

Make sure that your computer was turned on first (don't ask me why). Then hold down the Fn key while pressing F8. Hope that helps.

Multi-media projection without image

A great deal of the time DVD players are very restrictive on outputting to multiple sources due to copyright protection. In my experience, if you use your laptops function keys to toggle output (For example, on my laptop, I hit FUNCTION + F4 to cycle between LCD,LCD+VGA,VGA), you should be able to disable the laptop's LCD display, only outputting via the VGA cable. It's worked for me with my HP VP6111 and Windows XP in the past. Hope this helps!
