|"My PC has two outputs for monitors (does it mean that my video card can support two monitors?),.."|
"...when I plug in each monitor into each output only one is working"
The software enables only one by default. The other one you have to turn on yourself.
The Radeon 9200 chipset is supportedl by XP, it installs display drivers for it automatically, but newer more elaborate ATI software may have been installed from a CD or via downloads from the web. If the more elaborate ATI software was installed, when you look in Control Panel - Add/Remove Programs, there are several entries beginning with ATI - if you don't see that, the more elaborate software was not installed.
I have a computer with a Radeon 9250 on it - the software for it was installed from a CD that came with it. What I see on that computer for the settings for the card may be different from what you see, if only the built into XP support was installed for your card, but this should be the same.....
RIGHT click on a blank part of the main desktop screen, choose Properties.
That goes to Display Properties.
Choose Settings - Advanced - Displays
When you have more than one monitor connected to the card, you click on the triangular area at top left of the box for the other monitor to enable it. Click on Apply or OK to save the setting.
If you also have TV out capability, and a S-Video or a single RCA cable video connection to a TV, you do the samething when you connect aTV.
If you have the more elaborate ATI software installed, probably either a Control Panel was installed, or Catalyst was installed.
My computer has the Control Panel
If a Control Panel was installed, there are more settings with the red ATI icon on them in Settings - Advanced, and many of them have a Help button lower right you can click on to access the ATI help information.
One of them is Overlay - click on that - click on the Clone mode options button -
there are several ways you can set this mode when you have two monitors connected.
Standard - the two displays are identical
Theatre - the display is spread across both monitors??
Display Device Aspect Ratio - Standard or Widescreen
For more info, click on Displays - the Help button lower right - arrange multiple displays - click on the highlighted Clone Mode or Extended Desktop, etc., or search the Help topics, etc.
If you have Catalyst, there is a tab for it in Settings - Advanced you can click on to access it, and there's also an entry for it in your All Progams list some where.
It has similar settings to those in a Control Panel
