    Using SVGA output on Dell C840. How do you turn on the SVGA output on the Dell C840?



    I tried the fn-F8 toggle. I don't have a monitor plugged into the VGA port and I'm not able to specify anyting but a plug-n-play monitor in control panel for the second monitor. As soon as I try to toggle, the LCD goes blank for about 2 seconds then comes back on. Do I have to have a monitor plugged into the VGA port?

Hi there.
The keyboard toggle keys are Fn-F8, that should switch to external monitor.
Please post back with the results and for any additional advice.

Good luck and thanks for using FixYa!!

    H there.
    Yes you do need to have the external monitor plugged in to the VGA output to switch screens, you can't specify a secondary monitor until thats done.

    Good luck

Adapter does not chanrge


make sure its plugged in correctly and the wall plug is plugged tightly. I had a Dell C840 when the
charger got power it had a green diode that lit up. You could test your power supply with a volt ohm
meter. if the VOM is not showing any power coming from the power supply (assuming you have the
VOM setup to match the power output of the power supply) then the power supply is probably bad.
If it works then it could be the computers connection or battery.

Can I go from VGA to SVGA?


If the question is can I convert my composite video output to a super video input then the answer is NO,

The composite is coaxial (2 wires) the S-Video uses 4pins and there is no S-Video output on a Presario 1200 laptop.

You can however use a Multi-AV SCART adaptors with Input/Output signal switch where you plug in the composite video output into the top video and 3.5 mm jack stereo audio into the mono audio connections on top.( via a stereo to mono cable)

Does the dell dimension 2400 has an output to connect the to tv


You will either need a new video card with a compisite (yellow connector) or a s-video connector (looks like the end of a mouse), or somthing called a scan converter. Either of these products will allow you to use your telivison as a monitor for your computer. The last option is to get a telivision with a monitor connection on it. They are called SVGA connectors. If you go this way, you will need a Male to Male SVGA cable. Good Luck!

Laptop to TV


I dont believe that you can hook that model up to a TV you have to have a certin video output and it also would depend on your tv as well. But i am about 100% sure that series does not have the output you need you usally can connect via S-cable

Setting up S video out on Dell Inspiron 8200


I do this all the time with my ATI powered laptops... Right click the desktop, select properties, choose settings then advanced. You should have 3 screens. Laptop, Monitor and TV (I only get 'multiple monitors' no matter what I try...) You must have it connected before it will allow you to 'activate it' Once its activated theres a place for you to click to make the s-video / tv output your DEFAULT... Keep in mind that with some media players (windows for example) the movie image will only appear on the default screen- the other screen will be blank. So if you are intending to record to your VCR make sure that your TV is the Default.
