Connecting a second ldc display to my mac dual g5 and while it recognizes both monitors, it appears that they're flashing back and forth... as if they're trying to sink up? I only have a 64meg graphics card and wondering if that could be the problem? thanks in advance for any assistance! dc

How do I connect dell ultra sharp 24 dual monitors to dell 9020 mini tower

At the back of the unit you will see a graphics card output. If you only have one then you will need to buy a second one to utilise a second monitor. You will need 2 DVI outputs to run this kind of setup.

Dual display using the Intel G33/G31 Express

You need to get a graphics card that has dual video outputs that connects to separate monitors.
Getting a second graphics card won't work because they cannot work together.

I have a G5 Mac with a Power PC Dual Processor. When my computer seems to be doing too much it goes to sleep mode. At first I thought it was a over heating issue and then I thought it was a power issue...

check the setting of the G5, you might have it going into sleep more sooner than expected.

I have 2 monitors a syncmaster 920N and 216bw.Both were working fine until I had a system restore now only one works.What do I have to do?

Configuring your displays
Connect your second monitor, and then restart your computer so that it detects the new monitor. Once you have restarted your computer, you'll need to adjust your display settings by following these steps:
Click the Start menu, and then click Control Panel.
Click Appearance and Themes, and then click Display.
Once you connect your second monitor, you need to adjust your display settings.
In the Display Properties dialog box, click the Settings tab.
Click the monitor icon labeled 2, and then select the Extend my Windows desktop onto this monitor checkbox.
Extend your Windows desktop to your second monitor.
Troubleshooting: If you do not see two monitor icons, your computer might not support multiple displays. First, make sure that you have Windows XP installed. Then, visit Microsoft Update, click Custom Install, and install any available hardware updates. You may also need to visit your computer manufacturer's Web site to install an updated display driver. If you still do not see two monitor icons, you may need to install an additional display adapter, as described earlier in this article.
If necessary, drag the monitor icons so that they are arranged in the same way as the monitors on your desk. Click the Identify button to indicate which monitor is 1 and which monitor is 2.
Drag the monitor icons to match the physical arrangement of your monitors.
Click Apply. Windows XP will activate your new monitor.
Click OK.
A dual monitor setup enables you to view the same image side by side.
Once your monitor is set up, you can use your mouse to grab the title bar of a window and drag it to your new display. If a window does not move when you drag it, double-click the title bar first, and then drag it. Having two monitors will forever change the way you work with your computer. Be creative and experiment with the sizing of application windows and what information you can keep in constant view while doing multiple tasks.

Dual monitors

You'll need a dual-monitor video card in your computer. The GVLM1928 is basically two monitors on a shared stand. Each side of the monitor has a separate video connection.
