|Tell us the make and model of your brand name system.|
The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.
You must have the proper video drivers installed for your video adapter, of course, and they must have been installed the right way.
The original brand name software installation already has the proper video drivers installed, but it you have installed just Windows from scratch, you probably MUST install the video drivers yourself.
(If you have a really old laptop, e.g. made in circa 2001 or earlier, XP may have the video drivers built into it, but you may be only able to have one display with the drivers provided by Microsoft. In that case you need to get the proper video drivers from the web site of the maker of the laptop in the downloads for your specific model.)
In most cases (except for really old laptops that have separate monitor drivers for the built in display listed for your specific laptop model on the brand name's web site), the monitor drivers for your built in display are embedded into the drivers for your video adapter, and in that case the video drivers can't be obtained from the Intel web site.
We don't know what ports you have on your laptop until you tell us the specific model of it
I'm assuming it has a VGA port, and a "S-Video" port.
If you mean your built in display and an external monitor via your VGA port,
- or - your built in display and an external TV display via your "S-Video" port....
For any computer.....
VGA (and DVI) connections are NOT "hot pluggable". Plugging in or unplugging the video cable while the computer is running can DAMAGE the circuits of whatever you plugged in, or the circuits of the VGA port, or both !
If you're connecting the VGA port to a computer monitor, the video cable MUST be connected BEFORE you boot the computer.
If you're connecting the VGA port to a TV that has a VGA port input, the TV MUST be set to the proper INPUT the cable is connected to, BEFORE you boot your computer. E.g. VGA, PC, etc. .
For a display on a TV via a connection to the computer's "S-Video" port
- the cable that connects your "S-Video" port to the TV must be already connected to the proper port on the TV (a S-Video port, or a yellow RCA jack) BEFORE you boot your computer.
- the TV MUST be set to the proper INPUT the cable is connected to, BEFORE you boot your computer.
For any computer.....
XP often only enables ONE display by default.
When you have more than one display connected properly,
- RIGHT click on a blank part of the main desktop screen, choose Properties
(goes to Display Properties)
- click on the Settings tab.
If you have the proper drivers loaded you should see two large icons that look like monitors , and below that you should see
(a specific monitor name other than Default or unknown or nothing) on (the specific name of the video adapter)
- hold you cursor over the displays, one display at a time.
One of then will pop up "Not Active" - RIGHT click on that display icon and click on something to activate the display, click on OK at the bottom of the Display Properties window.
For laptops (and netbooks)....
Some laptops will display on an external monitor that's plugged into the VGA port, or the "S-Video" port, without you having to do anything.
If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model. (e.g. press both Fn and Fx ; x is a number.)
In either case, XP will retain the second display for the same Windows installation as long as the cable to the display is connected and working to the second display while loading Windows.
It's probably not called that.
A true legacy S-Video port has only 4 pin holes; a true legacy S-Video cable has only 4 pins on either end. Laptop video adapters, and video adapters on desktop computers, often have a "S-Video" port that looks the same as a legacy S-Video port, except it has more than 4 pin holes, that is physically compatible with plugging a legacy S-Video cable's plug, or a legacy S-Video to Composite (single RCA jack) gender adapter, into it, and the wiring of the port allows the legacy S-Video connection or Composite video connection to work
