I have sold over 100 of these (useless)... projectors so i can tell you that you need to;
go to display properties in the laptop and make sure you can see 2 screens otherwise you wil get nothing out of the video output/vga depending which model you have. go to the projector menu and make sure auto is set for the source/input. if your laptop has VGA out set optoma to VGA. start the projector up again and then the laptop in that sequence. if you need any more help email me.

I can't get the display from my laptop to project to a screen.


If you connect the data projector to your laptop and power it up first then your laptop, the video will switch to the data projector automatically.
If you had powered up the laptop first then you can divert the video information to the external video port/data projector by holding the Fn key and then press F4 key.
You can toggle between the LCD screen, the data projector or both LCD and data project together using the Fn & F4 keys.

Unable to transmit image to projector


Usually you can use a VGA connection cable to connect your computer with a projector. They also have inputs for s-video and RGB but these are much rarer on computers. Once you have connected the projector press the key on your keyboard that looks like a square with two lines on either side (mine is FN+F4) This will shuffle through different setups (mirrored to screen, extended to screen and back to normal) if this doesn't work try plugging in the vga cable and restarting the computer with the projector on.

Which function key allows to switch to tv


Hi there,
You need to press hold the FN key and press the F4 function key once which toggles the display to the External Display source like the television connected along with the LCD of the Notebook.
If the FN and F4 key combination is pressed again, the display will dissappear from the LCD of the Notebook and remain only on the external source.
If the FN and F4 key combination is pressed third time, the display will be back on the LCD of the Notebook and will not remain on the External display source.
Here are these details in other way :
First time pressing FN + F4    ---> Display on LCD and External display
Second time pressing FN + F4 ---> Display not on LCD but on the External Display
Third time pressing FN + F4 ---> Display back on the LCD and not available on External Display (Normal position).
Below are the details of what the Function keys in your DV1000 Notebook work :
fn + f1 Opens Help and Support Center fn + f2 Opens print options window fn + f3 Opens default Internet browser fn + f4 Switches the image among displays fn + f5 Initiates Standby fn + f6 Initiates QuickLock fn + f7 Decreases screen brightness fn + f8 Increases screen brightness fn + f9 Plays, pauses, or resumes an audio CD or DVD fn + f10 Stops an audio CD or DVD fn + f11 Plays the previous track or chapter on an audio CD or DVD fn + f12 Plays the next track or chapter on an audio CD or DVD fn + esc Displays system information.* (*To clear the system information display, press esc.)
Hope this helps...

Is your video source using a suitable resolution for your projector?

Is your laptop set to output video through the vga port? Try "FN" + "F4" on an HP, Fn+F7 on an IBM or Lenovo.

Is your projector looking at the correct source? TV / VGA / S-VHS etc...

Video projector from a laptop


You can connect the Projector to the VGA Port of the Notebook which is a Blue Port which can be seen at the rear of any desktop computer to which we usually connect the Monitor to.

The VGA Port will have 15 holes on it and should be in Blue colour.

You can locate the VGA Port at the Left side of the Notebook.

Locate the port according to the information available below :

http://h10032.www1.hp.com/ctg/Manual/c00726464.pdf

Refer to page number 14 (18 of 32) in the manual.

Once you connect the Projector to this port, hold the FN key and press F4 key once.

This wil get the Display on the Projector connected to the Notebook.

If you just want the display only on the Projector, hold the FN key and press the F4 again.

Now, if you want the display back on the LCD of the Notebook, Press the FN + F4 third time.

Hope this helps..

Hooking up projector to my computer


If it's a laptop, you might need to activate the vga output, using the blue "fn" button in combination with f4,f6, f7 or f8, depending on your manufacturer.

On an HP, you press FN+F4 once, to turn off the LCD, and use the projector. Press it again to run both at the same time, and press a third time to use just the LCD. The cycle repeats on each press.
