You should try booting into 'Safe Mode'. When you first turn your PC on, continue to hit F8 until it gives you a boot menu option. One of them should be to boot into 'Safe Mode'. Or you can choose 'Last Known Good" to boot into the last time it worked properly.

If you get into safe mode, try messing with the video settings by right-clicking your desktop and going to properties, and then go to the settings tab, and mess with the settings. If you have a video card program setting up your video, try going into that program and setting it to different settings.

This just sounds like a setting issue, when you plugged in the projector it changed your settings, and the PC is still trying to connect to the projector.

good luck

You might try holding down the function key and click on the button that switches you from an internal to external monitor, it look like a little monitor on the button and is activated by holding down the function key and then pressing the the key that controls swapping the monitor source.
the function key is marked with an "Fn"

Try hitting fn and f8 at the same time. this toggles between your laptop screen and the projector receiving the video signal.

Dear, i would like to know how and what cable i need to connect my laoptop to a home cinema 705 HD projector


Hello Jerrel43, Here is a quick overview: 1. You must first learn what port your laptop offers for video output. Your laptop could have one or several of the following: VGA (sometimes referred to as RGB), DVI, DisplayPort, S-Video, or HDMI. The following link offers pictures of each. http://hookpctotv.com/laptop-hd Keep in mind that DVI and HDMI offer the highest quality picture, so if your laptop has one of these, use them. 2. You must learn what port your projector offers for video input. After doing a quick search, it seems that your prjector offers VGA, S-Video, as well as HDMI. 3. Plug your projector into the computer with the port available on your laptop. Power on your projector and laptop. 4. Make sure your operating system is "outputting" (sending signal to) the video signal to the projector. This can be done in a few different ways (and varies according to which operating system your laptop is using). A) If you are using a Windows XP laptop, right-click anywhere on the desktop and choose the "properties" button. Click on the settings tab at the top right of the window that opens. Click on the blue box with the number 2 and then click the box below that says "extend my windows desktop to this monitor." At this point you should see and extension of your desktop background being shown by the projector. Just drag any window you would like off of the right side of your laptop monitor and it will show up on your projector.

Cannot get the Projector to see my emachines D620 Laptop screen. Press FN+F^ my computer screen goes dark but nothing shows at the projector tested the projector worked fine with other laptop


To check if the external video port on the laptop by connecting an external monitor to the laptop and see if it works. If it does work then the video port is OK and the only thing I can think of is :-
What is the highest resolution that the projector can display?
Is the video resolution on the laptop set higher than the projector's maximum resolution, if so reduce the screen resolution on the laptop.

I was having this problem also. I originally plugged my 3 video cables into the VCR outlets in the front of the vcr. I finally turned the vcr around and found two other sets of video out plugs. One was to a dvd/dvr and the other was a vcr out. I took the plugs from the front of the vcr and plugged it into the dvd/dvr out and it worked! Good luck with your problem. Hope the resolution is just as simple.

Projector does not display laptop screen


Many laptop computers do not automatically turn on their external
video port when a projector is connected. On many laptops, the activation function key is labeled with an icon or the text CRT/LCD.

Try the Function Key with the Icon of a monitor to enable the external video port.

If that does work, look at the settings on the projector using the buttons on the top.

Check the "Default Source"

Default Source toggles among Computer 1 analog, Computer 1 digital, Computer 2, and Video. This determines which source the projector checks first for active video during power-up. Highlight Default Source and click the left or right mouse button to toggle
among the options.
