Connect to non-network projector


The Engineer

Hi, I have tried to connect my new Dell laptop with Vista on it to the Optoma
DV11 projector using the supplied VGA cable.

I get NO IMAGE from the projector in spite of all steps shown below.

1. when cable is inserted Vista automatically changes DPI at 800x600. Is
there a way of stopping that ? Very annoying...Attempts to change DPI to
higher at this point crashed the system every time.

2. have changed DPI to mid range BEFORE connecting the cable. Have cheked
DPI is in acceptable range for Optoma. This time cable insertion did not
change dpi to 800x600. Pressed Fn + F8, projector says input acquired via VGA
channel but screen stays black.

3. have tried above with Windows Mobility Center, find New Display, etc..Fn
+F8 again, no luck

4. all Help in Vista is about network projectors , nothing about directly
connected projectors. Is a directly connected projector same as a New Display
or New Monitor ? Can Vista find the directly connected projector ?

Whatever I seem to be doing, changing DPI, pressing Fn+F8, uisng the
Mobility Center I get black screen on the projector although the projector
does lock on some VGA signal from the laptop.
Am I missing something essential here ? I would be very grateful for some
advice or help links, thanks.


Hi Engineer,

Try this method. Firstly, make sure that both your laptop and projector are
off. Connect your laptop to the projector. Switch on the projector. Next,
switch on your laptop. The image on your screen should be replicated through
the projector. Note that because the maximum resolution of your projector is
800 x 600 you will need to set your laptop to the same resolution. This is
because a projected image is the same image as displayed on the laptop screen
and there is nothing you can do about this - if you want a higher resolution
you will need a projector with a higher resolution. We sometimes have
meetings requiring a laptop and projector where I work and this is how we
connect them up. Although the make of our laptop and projector is different
from yours, there is no reason why this method shouldn't work.
