Connecting samsung monitor to my laptop

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 a few times. 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

You say the trouble is with the keyboard. Can you attach an external keyboard via USB and see if you can push Fn key with F5 (I think it is the F5 key - try Fn with others - keep Fn pressed and repeatedly press the F5 or F6 etc.) several times to see if the screen toggles between LCD and external monitor. For this to work you will have to restart the computer after attaching the external keyboard. Press the start button until the computer goes off, and press again to restart.

Itf you ascertain that the trouble is with the 99.N7082.01D, make sure to try to fit it in correctly, or perhaps the Fn key has some dust or liquid in it so it does not function. Then you have to try to clean it from the inside after you disassemble.

On most laptops, you need to turn on the external monitor connector from a function key on the keyboard. It doesn't automatically sense you've hooked up the other monitor. On your model, hold down the Fn key and press F5 to switch the external connector on. Here's the page from the user guide with the key combinations you might find helpful:

Try holding down the Function key (Fn), then pressing F5. Wait a few seconds. On most laptop, each press of the F5 key will toggle between laptop display only, projector only and Dual (same image on both - my favorite).

You'll probably see a little Monitor-shaped icon on the F5 key. It's possible it's another function key - on Dells it's usually F8.

Does the FN key still work with any other keys ?

If you know how to let it work with an LCD or DLP projector then all you have to do is set the selector of the your LCD TV to the RGB or computer input. If not, then you have to hit the function key in order to activate the secondary port for the external display of your laptop.

Try to double check if your connecting to port 1 of infocus, theres also a fn shortcut with your display setting i believe its fn+f8 or fn+f5 im not very sure  whats the command with asus try to doublecheck your user manual

press "FN" KEY and press F5 or F6 key if you post your
keyboard layout photograph so i can better explain

Following an advice in this forum I loaded the launch manager for the travelmate 6592, installed it and It put working on the silver P key of the laptop, i.e. the launch manager, and at the same time the fn+F5 key started to working on again. For a long time this key was disappeared from me laptop, just the same time that the fn+F5 key didn`t work.

Its not a malfunction. blinking light is indicator shows that no appropriate input signal detected. If you are using laptop refer your user manual to toggle to external display device. For example in most of the Toshiba Laptops requires to use Fn+F5 in order to use external display device like you have. If issue still persist you may post again by including the details of your laptop/desktop model.

Good Luck, Happy New Year
