How to connect my Dimension 1100 to my TV

it's an old school RCA tv,  having svideo and a RGB connection were both pretty new when i purchased it.  that counts out the DVI or VGA connection.  the only problem with your solution is that when i hook up to the tv i no longer have a working monitor on my computer.  do you think i can change my output device before rebooting and connecting to the Tv or will the computer not recognize the option to connect to the tv since it physically won't be connected 

Welcome to the forums :emotion-21:

Assuming your TV has a VGA connection of course, why not use the DVI or VGA ports on your graphics card, instead of using S-Video?

To activate TV Out:

Connect whatever cable you're using to both the computer and the TV, then reboot your system.

Once it's rebooted, open your graphics card's display options, and click on the video card's TV (/Output Device) tab.
Click Settings --> Advanced --> TV (/Output Device), and choose 'Enable output to TV'.
Different brands of video cards may have slightly different wording of course - i.e. 'Output Device/TV'.

(Restore the display back to your computer monitor by following the above steps, except choose to send the signal to the computer monitor instead of the TV.)

Make sure you've got the latest graphics drivers installed as well of course :emotion-5:

Hi djones0526, If you want to run your monitor as well as your tv, then you will need this HERE. As for your controls your tv manual will have info on your output settings.

The Dell B110 aka Dimension 1100 doesnt have TV Out.  It has PS2 ports, Audio, 4 USB, LAN, Serial Port and INTEL VGA video.

That said I would get a scan converter for Old TV.

It handles the monitor problem by doing VGA Pass Thru
