I would start by cycling this through the f4 option again first. Next I would connect the projector to the computer and then booting up the computer. Next I would disconnect the projector...turn it off, connect the projector again and then power up the projector. Try every combination of sequencing to get the computer and projector to talk to each other. It would not be a bad idea to change out the cable and try a new one as well. If it is a ceiling mounted projector then connect straight to the projector and try that.

SOURCE: Projector shows only 50% of the computer screen

mine does the same thing but i can see the whole screen it's just half height full width, above solution about zooming to 1X is what i've been doing to fix it for the last 6 months, needs to be done every time I turn the power back on. Anybody know of a more perminate fix?
Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....
Already replaced two blown diodes in the main H-bridge
Looks like one coil will need rewinding.
If anybody has one in pieces I would be great if you can help me work out what the blown transistor was.

Hi mrus821

If the signal won't go through you will have to either have your Mainboard Repaired or Replaced.

This is unfortunatelly a common Mainbaord problem , and the above is the only way to get it fixed.

SOURCE: Displays desktop background but nothing else

I discovered that my laptop supports two monitors and the projector was acting as monitor #2. By changing the priority of the monitors I have got the information I need on the screen, but now not on the laptop. However, I can work the two from the screen and that will suffice for the moment, until I can find a way of getting the information on both!

I can see my background but cannot see anything else


Hi,

The Fn+F8 in some laptops or Fn+ KEYS WHICH HAS MONITOR ICON OVER FUNCTION KEY) command tyically runs through 3 modes: Extend desktop, Laptop only, Projector only.

Mirroring displays (meaning you see the exact same thing on both screens) is not always on option on a PC; the ability to do that is dependent on the graphics card and drivers in the laptop.
Not seeing the exact same thing on both screens is often the preferred way, but when you don't see all your desktop icons it can be a bit confusing.

The trick here is that when you want something to show on the projector, you grab the window you're working with and drag it over to the other monitor. Why this is preferred is because you can be showing a powerpoint presentation on the projector, while you have a script or notes open in Word on your laptop display to read from. You see, you don't see anything but the desktop background on the projector because you haven't moved anything over there yet.

Your laptop is in extended mode, try changing to Laptop mode, should solve your problem or try dragging the required file to that monitor as said above

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

MacBook connected Hitachi CP x301 Icons do not appear


Ok what's happening is that you have it set up as an extension of your desktop, you need to mirror the displays. when your projector is plugged in and it is showing only the desktop background, open "System Preferences," click "Displays," click "Positioning" and check the box that says "Mirror Displays." This should do the trick.

1 Answer

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

No live picture on Benq digital projector


seems to me like your acer laptop's display is configured " extend my desktop to this monitor", that's why you can only see the desktop background. Go to your display properties and change it to clone display or uncheck the extend display option.

AOL Optimized PC - desktop acting odd


Hi I'm not sure how to change it but I have a suggestion that might work. Here are the steps to try: Go to START then RUN type in msconfig In the next window that pops up, select STARTUP tab Check in there and see if any startup item belongs to aol. Uncheck all those belonging to aol. Click apply, then click Close. It will ask to restart. Click on restart and see if it still happens when it loads up windows again. Good Luck Lolita
