Laptop on, presentation loaded, projector funtioning and will show menu on projector screen but no presentation will display. What else do I need to do, please?


You may have to adjust the resolution your notebook is displaying at in order to make it compatible with the resolutions that will work with your scanner.

For example, most new notebooks display at 1380x760 or 1440x900, which are 16:9 ratios most suitable for movies.

Most projectors display at resolutions with ratios of 4:3, like 1024x768.

For Windows, right-click on a clear area of the Desktop and choose Properties... or Screen Resolution. Change the resolution to match your projector.

Projector works fine, but does not show video


Hey. Sounds like you are using some kind of dual-view or extended desktop via the computer for video. This may sometimes be a problem. If you can see the desktop but no video using the projector it is not a projector problem. It is probably your grapic card och software problem.

Try different setups in the graphic cards settings, like the projector as primary monitor etc. That usually solves the problem.

You might have not enabled your computers second display.

This is actually a very nice feature, because you could run your powerpoint slide on the monitor while still running your normal applications on the laptop screen.

Go into control panel, display properties and then click on the "second" monitor (you could click on "Identify" to see which is which) and then select the "expand my desktop onto this screen.

The LCD display will be just a normal background, but you can drag windows from your laptop screen onto the LCD and back.

Hope this helps

Laptop computer connected to projector.


When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.

But once you find your dual display options you will be able to change it to make both displays the same

The projector doesn't show what is on my screen


your projector may be on the 2nd screen or presentation mode of your video card. open an application and drag the application window off your screen (try both sides) and see if it will appear on the projector.

"no signal " on the screen


After half a day of tinkering around with my new Acer I fixed my problem, which I think is yours also. I connected it to my notebook, it read the signal 'D-Sub' or something like that, and after my notebook finished startup, it reverted to no signal. I tried it with my desktop and it worked just fine. The display will only show up on one output device. It worked fine on my desktop because I was unplugging my monitor in order to hook up the projector. Hooking the projector up to my notebook left the display panel still active and that was where it displayed. In case I'm not making sense, the solution is this: After setting everything up, hit Control+Alt+F1 to switch display from your screen to the projector. To switch back, hit Control+Alt+F3

Hi Abouttime

This is unfortunately a sign of Mainbaord damage to any make of Projector.

But do give this a go , you've got nothing to lose.

Try using a different signal cable and then pressing Auto on either the remote of the Projector or the Projector it self once the line appears.

Thanks for using Fixya !
