    F8 is a Function key. What computer is this, (Computer manufacturer name, and model number? The Dell Optiplex 740 PC Desktop heading, may not be correct for the computer in question) Also what monitor is this?

Did you install an aftermarket video card? If not, generally you can change setting from your desktop. Right clikc on desktop, select Personalize or properties (depends on version of Windows). From there select display settings and select you monitor. Otherwise try holding down the control button while pressing the F8 key.

Dell 1703fpi


Dell 1703fpi LCD monitor,

http://philadelphia-pa.americanlisted.com/computers/dell-1703fpi-17-lcd-monitor-vgadvi-usb-hub-50-phoenixville_21225579.html

I got that part Dan.........

What I need is what Model Number of Dell Inspiron it is.
This is on the Bottom of the Inspiron laptop.

Why?
Because I do not know if the Dell Inspiron laptop you have, has a DVI port, or a VGA port; for an external monitor......

Generic information while I wait.........

Example of Digital Visual Interface port, and corresponding cable,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

Example of Video Graphics Array port,

http://en.wikipedia.org/wiki/VGA_connector

Can be on the side, or back of laptop.

Laptop OFF, monitor OFF, connect the matching video cable from the external monitor; to the laptop.
Now turn the laptop on.....

By factory default settings, the display should now show on the external monitor. (Dell 1703fpi)
No?

There are at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external monitor
3) External monitor ONLY

Press, and hold down on the Fn key. (Usually 2nd key from left on bottom row of keyboard)
AT THE SAME time tap once on the Display Toggle-Over key.

Which one is that? Dunno.
Laptop model number was not stated.
For a Dell Inspiron though, it's usually the F8 key.
(F1 through F12 keys at the top of the keyboard)

Hold the Fn key down, and at the same time tap once on the F8 key.
Still no?
Hold the Fn key down again, and tap once more on the F8 key.

IF, F8 is the correct key for Display Toggle-Over, and there is no display on the external Dell 1703fpi; then I suggest you have a problem with the video chipset; on the motherboard.......

Awaiting reply in a Comment.

Regards,

Dell latitude D630 wont recognize projector


Connecting an External Monitor or Data Projector
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

Presentation mode is off appears when you try to FN F8 Dell Latitude E6500


check device manager to be sure your video card is functioning properly. If it looks good in device manager, shut off the pc, connect the external monitor/projector to the pc and start up the pc with the external device powered on. if no video from external device, then the video card/external connector is probably bad. Contact Dell if in warranty.

maybe the fn/f8 keys are not working. Can you get a safe mode boot prompt by repeatedly pressing the f8 key immediately following power up on the laptop? if no, f8 key is likely dead and you need a new keyboard. If f8 is okay, does the fn key work with other functions? if no, fn key is bad - new keyboard.

Hope this helps!
