Connecting an External Monitor or Data Projector You can switch to anexternal monitor or data projector by two methods.1. Connect the externalmonitor to the laptop's video port, power up the external monitor first and thelaptop. The video information will automatically switch to the externalmonitor.2. If you power up thelaptop first then you can switch the video output to the external monitor bypressing the Fn key and one of the Function keys, depending upon your make andmodel laptop. You can also toggle between the external monitor or both LCDscreen plus the external monitor or back to LCD screen only by pressing the Fnkey plus one of the function key. Here is a list of keycombinations for some of the laptops :-IBM ThinkPad = Fn + F7HP and Compaq = Fn + F4Toshiba = Fn + F5Dell = Fn + F8
Connect your projector to your laptop using a VGA cable. Now turn ON your projector and your laptop.
To make your screen projected, look at your function keys (F1 to F12). Look for the icon which looks like a laptop LCD and a TV. It should appear like LCD icon/TV icon. In some model it is in F4 while F3 in Lenovo. Example, you found the icon in F4, just press and hold down the FN key and press F4 to send your desktop image to the projector. This combination is called the "dual monitor" setup which in your case, the second monitor is a digital projector.
One of the F keys will toggle between the Laptop Screen and the VGA output - look at the F keys and see if one has a picture of a screen often F4 / F5 - needs to be used with the FN key
FN key+ F4 Key (Or which ever key has the symbol on)
It will toggle between
<laptop screen only><laptop screen and VGA output><VGA output only>
Not necessarily in that order
