try pressing FN on your keyboard then press F3 = FN+F3 at teh same time to project waht is in the laptop to the projector........
if not go to desktop right click anywhere select display properties it should give you the option to select the monitor and projectors detected by the laptop to show what is on you laptop as well posbbile u will need to either expand or if the option cloning will be present to have both show on the laptop and desktop ^_^
start the connecting all over again, by following the steps below:
1. Turn your computer off.
2. Connect the cable from the computer to the projector. If you want to
have your monitor to be hooked up as well, connect a splitter to the
video out port (DVI or VGA). You can also just hook the projector up to
the second port on your video card (If you have one) or if you have a
laptop, you can connect to the video out port on the back.
3. Turn the computer on and boot into your desktop.
4. Turn on the projector. Most projectors have an auto detect function,
that will detect a video signal and auto configure the projector to
display that signal. If you have a laptop, you have to hit a function
key to activate the second display. Usually this is FN Key + F5 or one
of the F Keys across the top of the laptop keyboard. It looks like two
squares, one empty and one with something in it.
5. Adjust the focus, brightness, contrast, and color on the projector.
6. Aim the projector at something white. Try not to aim it at something highly reflective.
7. Step back ... Load up your favorite game or video ... and enjoy.
Your project should work, after following the above instruction.
This sounds like a bad cable... do you tight the scew? inspect the cable connector at each ends to dbl check that there is no damaged pin, and also on the projector side...
A usb cable will not work that way--on your projector, it's used for data...you need to obtain a monitor cable which will plug into the vga connector on the laptop and into the connector on the projector (rgb in 1) or (rgb in 2) If you use the #2 rgb input, make sure the button IS NOT pushed in! If it is, the projector will be switched to OUTPUT mode on the #2 connector. Also, on the laptop, normal operation is "laptop only"...when you push the <alt F4> buttons, it should then switch to "laptop + external display(projector)", another <alt F4> push will give "external display only" mode. Then, another push will return you back to "laptop only". NOTE: Sometimes, you have to turn on the projector first, then immediately turn on the laptop--not to get technical but different equipment can get finicky about syncing up...just something to be aware of...
The signal type settings wrong in the menu, or broken interconnection between input board and mainboard of projector, due to shocks during portable use.
just a shot in the dark. this reminds me 'bout a problem with a Optoma (or maybe it was a Ask) i fixed. In that setup menu (on the proj), i was able to adjust the sync signal on the input. (I don't mean the the screen refresh rate..) Just tried gradually step by step. Worked then!
