Well the ax-100 can only display 1280x720. If you output anything different - lower or higher - the image needs to be rescaled, which inevitably makes it a bit fuzzy.

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.

I think your best bet will be to contact Panasonic Customer service. But the most common cause for this is that the lamp connections weren't properly re-installed, or there's an interlock switch that is in the wrong position from when you had the lamp(s) out.

I have a Panasonic pt-ae900u projector that doesn't project an image. The lamp fires up but no light makes it past the LCD panels, no video or menu graphics, would be appreciated

I have the exact same issue with my projector and was wondering if anybody has an idea what the problem/solution could be? Have checked all internal connections, wiring, etc. but nothing is physically wrong with it. Powers on and off with no issues; bulb is working but no light out of the lens. Please help!

    Projector keeps turning off every 5 mins

    if just the lamp turns off and the rest of the projector is running, it's time to change the lamp. if the whole projector turns off (not goes through shut down), it may be a power supply problem.

    Presentation mode is off in laptop

    use the remote control or the menu button on the projector - navigate the menu system of the projector and one of the options should be able to alter the presentation mode from off to on.

    If you post back with the model of the projector can either post a link back with a pdf manual for it or if you read the manual it should show in there how to enable the presentation mode.

    Also ensure that you have the projector and laptop connected via the relevant cable ie vga or dvi before you switch the laptop on.

    Also ensure if its got an intel graphics card to use the intel or graphics card utility to enable dual display or clone display mode and that the projector is switched on before you turn your laptop on.

    right click in free area on your desktop --> properties --> display --> and configure it under the advanced section with regards to getting your laptop to display on the projector

    configuring your graphics card for the projector will vary from graphics card to graphics card as the drivers are different between manufacturers and they place things in different places.

    If you also post back with what make and model of graphics card you have on your laptop I can try and assist you further with how to ensure your laptop is outputting to the projector.

    Also if it displays funny then lower the resolution on your laptop as well as the display frequency / refresh rate as the output from the graphics card on your laptop has to match what the projector supports ( this will be in the manual of the projector in terms of what display modes it supports )
