The projector doesn't work with my laptop

Hi there, i have connect my laptop through a new VGA cable to IBM projector C400. My laptop detects the projector but the projector doesn't detect the laptop, What should i do?

Decrease the screen resolution of your computer to the minimum possible value and check.
Probably the projector does not support the resolution of the laptop. With a lower resolution it might work.

Your laptop should have a FN key and an 'F' key (The image on the key looks like two monitors side by side or it will say LCD/CRT) which you need press simultaneously to allow the laptop to send the signal out through the VGA port. Usually I have to repeat the process three times to allow the image to be presented on both the laptop screen and the projector. If this still doesn't work, go into desktop properties, advanced and unclick the square saying 'extend to..............' (sorry I can't remember the rest of the extend bit as I am in front of my PC not laptop and the settings are different. You should find it though.

Good luck

The screen resolution on your laptop may be set too high for the data projector. Try reducing the laptop's screen resolution down to 1024 X 768.

I don't know the model of system you are using. But before your system can detect the projector, you need to press some key conbinations.

for HP Laptops the key is Fn+F5 key
For Lenovo/IBM the key is Fn+F7 key.

Try setting the resolution to a value compatible with the projector and try again.

try pressing FN on your keyboard then press F3 = FN+F3 at teh same time to project waht is in the laptop to the projector........

if not go to desktop right click anywhere select display properties it should give you the option to select the monitor and projectors detected by the laptop to show what is on you laptop as well posbbile u will need to either expand or if the option cloning will be present to have both show on the laptop and desktop ^_^

Hello...the resolution on the laptop is too high...at least, from your description, that's what the problem sounds like. The projector is capable of 1024x768. Make sure the res on the laptop is set at or below that number. To set the res on the laptop, go into control panel and choose the display option...under settings menu, there will be a slider that you can move--when you move this, the computer will ask you if you want to keep this setting--choose yes. Also, make sure you power up the laptop first, then immediately after, power on the projector--this will help stop any syncing problems that might occur.--Hope I helped you!--Rick

try hitting function 8, had the same problem giving a presentation and that took care of it.

I have the same problem with a Hitachi CP-X345 Multimedia Projector. My Acer Aspire 3630 Laptop cannot be detected but it works without incident with a Dell Vostro 1500; just plug and play. Desktop settings to second screen doesn’t seem to help.
