Can I connect a second monitor?

March 13, 2009 at 05:59:12
Specs: Windows XP
I need to connect second monitor to my Desctop PC, Windows XP Professional and I 'm using ATI mobility/Radeon 9200 AGP , DAC(400MHz) , Bios Information BK-ATI VER008.017D.033.000. My PC has two outputs for monitors(does it mean that my video card can support two monitors?), but when I plug in each monitor into each output only one is working. Can somebody please help me, do I need a special cable, or a special software?

"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

Hey thanx Tubesandwires a lot !!! That was very helpful and clear. I also have to get a different cable. I thought I was able to use the output from my internal video card, but when you integrate another video card the first original one seems to be disabled.Thanx a million anyway.

The term video CARD is frequently used incorrectly. It's CARD only if it's removable - can be plugged in and unplugged, AND it plugs directly into the mboard, inside the case (e.g. a USB connected video adapter is not a card either). All video is a video adapter or a display adapter or a graphics adapter but onboard (built into the mboard) video is NOT a video CARD, it's merely a video chipset built into one of the main chipset chips, or on pre-pentium mboards, sometimes it's a separate chip on the mboard.It usually has no ram of it's own on modern mboards (on pre-pentium mboards sometimes it does), and must share the ram installed on the mboard. A true video CARD always has it's own ram.

In almost all cases, when you install a video card in a slot, doing that automatically disables the onboard video, and if it does, the settings regarding how much ram is shared with the onboard video in the bios are ignored by the bios.

Sharing the ram installed on the mboard (some mboards have a small amount of ram built in) with onboard video drastically reduces the max bandwidth the ram can achieve - the max data transfer rate - it's as much as halved.
The same ram will perform much better when the onboard video has been disabled and the ram is no longer shared - it's most noticable when something benefits from a faster data transfer rate being available.

You can install more than one video card in slots, and they will probably all work, if the video chipset is recent enough (e.g. first released after 1998 or so) that it can co-exist with another video chipset being present and working.

"I also have to get a different cable."

You can adapt most DVI monitor ports on a video card or on onboard video so they can be used with a VGA monitor connection by using a standard DVI (male) to VGA (female) adapter, or a DVI (male) to VGA (female or male, depending on what you connect to) cable, but you can't do the opposite - adapt a VGA port so it can be used with a DVI monitor connection - a VGA connection doesn't have enough wiring connections to make DVI work.
