You want to use a second monitor for presentations and you don't want to show your desktop?

The following is from Microsoft Help and Support:To install additional monitors # Turn off your computer. # Insert your additional Peripheral Component Interconnect (PCI) or Accelerated Graphics Port (AGP) video adapter into an available slot. # Plug your additional monitor into the card. # Turn on your computer. Windows will detect the new video adapter and install the appropriate drivers. # Open Display in Control Panel. # On the Settings tab, click the monitor icon that represents the monitor you want to use in addition to your primary monitor. # Select the Extend my Windows desktop onto this monitor check box, and then click Apply or OK. If the check box is not displayed on your computer, it may be because your video adapter does not support multiple monitors. See Notes for information about compatible hardware. Notes * To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display. * Selecting the Extend my Windows desktop onto this monitor check box allows you to drag items across your screen onto alternate monitors. Or, you can resize a window to stretch it across more than one monitor. * To use the multiple monitor support feature, you need a PCI or AGP video adapter for each monitor. If you have an onboard video adapter (one that is not a plug-in card but is part of the motherboard) that you want to use as part of a multiple-monitor configuration, it must be set as VGA. To find hardware that is supported by Windows operating systems, visit the Windows Catalog on the Microsoft Web site. * If your computer doesn't recognize your second monitor, click Display Troubleshooter for more information. * The operating system always needs a VGA device. The computer's BIOS or EFI detects the VGA device based on slot order, unless the BIOS or EFI offers an option for choosing which device is to be treated as the VGA device. * The VGA device cannot be stopped, which is an important consideration for docking units. * The monitor that is designated as the primary monitor will display the logon dialog box when you start your computer. In addition, most programs will display windows on the primary monitor when you initially open them. * If you are using Dualview, skip steps 2 and 3 above. Just plug your second monitor into the video out port on your portable computer, or into the second video out port on your desktop computer. When you turn on your computer, it should recognize the second monitor. Follow steps 5 through 7 to extend your display to the second monitor. If the second monitor is not shown on the Settings tab, you might need to update your display driver. When using multiple monitors you may configure the computer to show the same information on all monitors or you may configure the computer to show separate information on all monitors.If you do not show the same information on all monitors you can drag windows from the main screen to the alternate screen.


How can you set up a computer with 2 to 4 video screens?

To enable multiple monitors, your computer must have multiple monitor outputs. These outputs can take many forms (such as VGA or DVI outputs) and your monitor will need to have the same plug type as the output. This may (and most likely) will require that your computer have multiple video cards. If your computer currently uses built in video, to add another monitor, you will need to purchase and install a new video card as well as a new monitor. Windows currently has fairly robust multiple monitor support and after installing the second monitor will most likely autodetect it and "extend" your desktop onto your new monitor.


Can you extend your desktop over 2 monitors with an Intel Graphics Media Accelerator 3150 in Windows 7?

There is no way to extend your screen with an Intel Graphics Media Accelerator 3150. The graphics card is simply unable to extend the screen between 2 monitors. I did some research to see if you could, and the graphics card is just incapable of preforming the job. I did find a program that will do this with windows 7 starter, but it cannot with this type of graphics card. ( I have an ASUS Eee PC 1015 PE net book with this graphics card and windows 7 starter.) This problem also doesn't work on Home Premium or any other version of windows (Including Xp) if you have this type of graphics card.


What are S-video and AVi ports used for?

S-Video ports and AVI ports are used to connect a computer to a monitor/television screen. S-video usually works with older television sets and some monitors. AVI used to be the most common way to connect a computer (desktop or laptop) to a monitor. Currently HDMI and DVI dominate the commercial market. As for uses: people use them for dual/multi-monitor displays; to extend their workspace. You can also connect your laptop to a better monitor/television and then you can watch a video in better quality. Hope this helped!

How do you run windows on two different moniters?

I'll answer as far as Windows XP is concerned. Other versions may require different steps. 1) Have a video card that has two outputs on it! THIS is very important. You can also do this if you are using a laptop that has a video output connection. 2) Hook up both monitors to the computer. 3) Click on start, Control panel. 4) click on display 5) go to the settings tab. In there (if all the drivers are installed you should see some options to setup the second monitor. Good luck!
