Basically it is very simple to connect laptop with projector but
there may occur some problems
Which can be avoided very simply
Common projection problems are:
1) The user does not know
how to set the laptop so that an image is sent out to the
computer projector.
2) The laptop goes to sleep during the presentation and the signal
being sent to the
projector is terminated.
3) The screen saver comes on during a presentation and the signal
being sent to the
projector is terminated.
4) The laptop’s resolution settings are set improperly so that the
projector is not being
fed the correct image
resolution.
Step 1: Check your power
Always use the laptop’s power adapter when projecting. This will
not affect your ability to
project, but it will eliminate the possibility of your battery
going dead mid-presentation.
Step 2: Set your laptop’s Energy Settings
Set the laptop’s Energy Settings so that the laptop NEVER goes to
sleep or into an energy
saving mode. If your laptop goes to sleep during your presentation
the hard drive will spin
down and you will lose your projected image.
To turn off all power saving features:
Click
“Start/settings/control panel/Power options”
In
the “Power options” box choose the “Power Schemes” tab
Set
all 6 pull-down menus to “Never”
Under “Power Schemes” choose “Save As” and type in the word “projection”
Click
“Apply”
Click the “Advanced” tab
Under “When I close the lid of myportable computer” choose “None”.
Click “OK” to save and exit the “Power Options” menu.
So now every time you use the laptop for projection all you have to
do is open the “Power
options” window and choose the “Projection” profile under “Power
Schemes”.
Step 3. Set the laptop’s Display Settings
Set the laptop’s Display Settings so that the resolution matches
the native resolution of the
projector. The most common native resolution of our computer
projectors is XGA, or 1024 by
768 pixels. You can check the native resolution on our Computer
Projection page. To set the
resolution:
Right
click on the desktop.
Click
the “Settings” tab.
Set
the “Colors” to “True Color (32 bit)”.
Set
the “Screen area” to “1024X768 pixels”.
Click “Apply” (if confirmation window opens click “OK”.)
Click
“Advanced”.
Click
“Displays”.
In
the center pane marked “Panel” click the round blue dot so that the Panel is
“Primary”.
Click on the word “Panel”.
Under “Panel Attributes” make sure “Scale image to panel size” is checked.
Click
“OK”.
In
the left pane marked “Monitor” click the little blue wedge to the left of the
word
“Monitor” so that an image is displayed on the picture of the
little computer monitor.
In
the left pane marked “Monitor” click the round blue dot so that the Monitor is
“Secondary”.
Click
“Apply”.
Click
“OK”.
Step 4: Send the image out to the projector
Learn how to send the image out to the projector.Audio Visual
includes directions with all its
computer projectors instructing the user to do the following things
BEFORE you power up
your laptop:
Connect the laptop to the projector with the supplied computer video cable.
Turn the on the projector
Ensure the correct source is set on the projector controller P.C. or laptop.
Now
you can turn on your laptop.
If this procedure is followed the laptop will automatically sense
the presence of the external
projector and send the signal automatically out to the projector.
Troubleshooting Problems
1. When it does not work: For various reasons, including failure to
follow the procedure in step
#4 above, the user will get an image on either the laptop OR the
projector, but not both. In
order to turn on both the image to the laptop and the projected
image you have to use the
laptop’s function keys to turn on the display(s).
you can use the “Function/F8”key combination. Pressing this key
combination
several times (waiting several seconds between pushes) will toggle
you through 3 different
settings:
• Image on projector only
• Image on laptop only
• Image on both laptop and projector
The Function key combination may vary depending on the make of the
laptop computer. Look
for a small monitor or the word “LCD” on one of the “F” keys.
