Labtop Monitor displays breifly then goes to blank screen

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:

Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.

Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

Probably press FN key and F5 or whichever F key has the screen symbals on.

If you have not done so already, hold down the "FN" key next to the spacebar and press the "F5" key. This sill cycle through the display options. Laptop only, External display only and both the laptop and external display.

Try pressing Fn + F4. You might've switched the display to the external VGA port by accident.

If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Hello,

Pls change the display settings of your laptop to 800x600 or 1024x724 then check. The projector SVGA.

Pls tell if you are not able to solve the problem.

F1 = Fuse 1
You should be able to locate a surface mount fuse at your local electronics store.

The video resolution and/or frequency that's set in windows is not supported by the monitor you have plugged in. Restart the PC in VGA mode (hit F8 after the BIOS messages but before any Windows messages) and change the video settings to something basic, such as 800 x 600 @ 60 Hz. Then restart the machine normally.
