I don't know what fn f4 or fn f8 do.

Press and hold the "Fn," or function, key on your EEE PC-1000's keyboard.

Press "F3" while holding "Fn" to lower the brightness on your monitor.

The brightness on your computer decreases each time "F3" is pressed.

Press "F4" while holding "Fn" to increase the brightness on your monitor.

Each time "F4" is pressed, the brightness increases.

Press "F8" while holding "Fn" to decrease the volume from your EEE PC's speakers.

Each time "F8" is pressed, the volume decreases.

Press "F9" while holding "Fn" to increase the volume from your EEE PC's speakers.

Each time "F9" is pressed, the volume increases.

Press the "Ins" key while holding "Fn" to take a screen shot, or make a copy of what is currently on the computer screen.

hope this helps

Hello.

Look at your laptop keys and be certain that Fn + F8 is the right combination. Could be Fn + F4, depending on your laptop.

If the key combination is OK, your VGA cable (from the projector to the laptop) could be faulty.

Hope this helps.

I think you have to reset through setup F12 or is it F8 restart and push one or the other, then locate menu for screen click to enable.

Haven't come across this before. Best I can suggest?

Fn + F8
It cycles through three options:
Internal LCD - Both - External output

Cheers

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...
