I have hired a projector for a talk I'm giving, have connected the laptop to the projector and I get the desktop background displayed or the screensaver, but nothing else. Pictures as a slide show do nothing.
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 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.
Which connection type are you trying to use (VGA, HDMI, etc). It would help to know what kind of computer you are using and whether you are using the projector as the only display or trying to do multiple displays.</br> If using a laptop then check and see if you have a key to switch displays. It will usually be one of the function keys (F4, F5, etc) and will most likely be a secondary action of the key requiring you to hold down your FN key then push the function key. This will switch between your laptop's outputs.</br> If using a desktop you need to go to your display properties. Win7 right click the desktop and go to Screen Resolution. You need to make sure that the Multiple Displays setting is set to Duplicate These Displays or Extend These Displays to make sure that the display adapter is sending a signal to the projector.
You don't say which operating system you are using.
You don't describe what steps you have tried.
Therefore, the advice I give can only be general, rather than the specific advice I might be able to give if I had more background information.
To send the screen image from the laptop to an External LCD TV, Desktop PC Monitor or a Projector with a VGA or HDMI Cable:
Connect the cable to both devices > power up the laptop > simultaneously press the Fn key + a function
key with the picture of 2 monitors (usually F5, F6 or F7) after the computer
has booted into the Operating System's desktop and settled down. I hope this

For Windows 7 and Vista- Close or minimise all windows, right click on the desktop and select "Screen Resolution". Press the "Detect" button and if another display comes up, on the dropdown menu labelled "Multiple displays" select either: "Duplicate these Displays" to show the same image on both screens
"Extend these displays" to have 2 separate displays (the position of the second display can be changed by dragging the box labelled "2"
For Windows XP - Close or minimise all windows, right click on the desktop and select "Properties" and then the "settings" tab. Click on the greyed out box labelled "2" and Tick the box labelled "Extend my desktop onto this display". click apply.
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
Please leave me comment, if you need further assistance
stop the dual monitor moded and it will project what is on the Desktop screen
for this right click on desktop -> properties -> (on the window) Settings here take away the check box for "Extend my Windows desktop to this monitor" and you can have what ever is displayed on your desktop on the screen
but if you keep the the existing setup then you can just drag the windows to the right or left edges and it will move on to the screen and you can use the projector image as an extended monitor, this will be useful when you want to have your presentation and your background work/ Document seperate from the viewing audience, try it you may like it
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.
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
on your display properties, switch windows to appear on your laptop. and do not connect your LCD when booting your PC. there is an option in display property that says extened your windows to this display... that is your LCD.
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.
