ADDING A SECOND MONITOR TO THE ALL IN ONE COMPUTER

Most laptops have a VGA port so an external monitor can be added. Then you might have to press a Fn key combination to get the other monitor to display.
If you want to add a second monitor to a Desktop computer, you'll need to install another graphics card. A USB adapter card is available; do a search for different models available.

If neither of these answer your question, please explain exactly what you need a monitor to display from; you posted to the Network and Wireless Adapters section, which is confusing..

HAVE YOU THOUGHT OF KVM.

You need to connect both monitors to a computer. Monitors do not daisy-chain (in general). The exception are some SCART-enabled monitors.

What is your source (desktop)? What is the make/model of your new monitor? Please add a comment with the video outputs/inputs for your source and second monitor.

Many newer desktops have two or three outputs. (Some video cards have display port outputs which with active adapters can support 2 monitors each.)

If your computer has two or more outputs and your new monitor has an input compatible with the extra output, get the appropriate DVI, DVI-HDMI or HDMI cable for your new monitor. See the next section if both monitors have VGA input.

If you have a desktop with only one video output, you may be able add a video card to support two monitors. (Depending on your computer, you may need to upgrade the power supply to support a video card.) Then get the appropriate adapter or cables to add the second monitor. (Note: if both of your monitors have only VGA inputs, check the specs for video cards carefully. Not all modern cards support analog outputs on their DVI, HDMI or Display Port connections. These digital outputs would require a digital to analog converter to give the VGA out.) However, if one of your monitors will accept DVI digital signals and the other VGA, add a card with one of each of these connections and a DVI cable to match. (This is an if needed extra; many monitors still ship with only a VGA cable.)

Then turn off your computer, open it and add the video card. Install the drivers with only one monitor attached. Then power down the computer and connect the second monitor. Turn on both monitors before turning on the computer again. Most of the time, the second monitor should be recognized (by Windows) and the appropriate refresh rate and resolution chosen. If not, you may need to enter the Display settings to set the monitor up.

I have seen some computers/video cards where only one output is initially enabled. You may have to go into the device settings to enable it. (Laptops often need their external video ports enabled in the BIOS.) Bad video ports/cards/cables do happen so RMA if needed.

The USB video adapter, http://www.newegg.com/Product/Product.aspx?Item=N82E16812225007 , can be added to a desktop to give a second VGA output but it isn't the best solution. USB bandwidth limits are significantly lower than those for a PCIe x16 slot or an old AGP slot.

I hope this helps. Please add more information about your system if you want more assistance with this problem.

(who has done dual monitors with older and newer computers. My old Pentium 4 with a Radeon x1350 video card was fine for driving a VGA monitor and an HDMI monitor (using a DVI to HDMI cable). My second generation i5 and P8Z68 motherboard system is also fine using the on-CPU video graphics for those same monitors. A video card would improve gaming but isn't required.)

By adding a monitor, are you trying to set up a multiple monitor display? If so, you'll have to enable your second monitor after you've connected it using the display settings in your control panel (or by pressing the Windows key + P in windows 7).

That means that the monitor is not getting a signal from the computer. There are several possible issues involved. 1) Make sure that the computer tower is on. 2) Check that the video cable is connected to the active port on the desktop. (Computers often have video connections on the motherboard and an added video card. The motherboard connection is disabled when the video card is active. Similarly if there are several ports (VGA, DVI, HDMI, Display port) only one may be active.) 3) Try a new video cable (if possible) and one of the other video ports (again if possible). 4) Try connecting a different monitor to the computer or connecting this monitor to another computer.

Open up the computer and check if the card requires a separate power connection to the power supply. Make sure it is plugged in. Do the fans in the computer spin up?

If a second monitor doesn't work or the monitor works on another computer, then the problem is with the video adapter on the computer, the power supply or the power switch. Please add a comment with more information about the type of desktop and the current video graphics adapter (on the motherboard or separate card). I will provide additional help if possible.

(who has a computer in the company that needed a new monitor (power supply failed) a few months ago and lost the fan on the video card last week. Without the fan, the card overheated and shut down. Thus no signal to the monitor.)

If you can see a DB15 port anywhere on your laptop, you can connect a second monitor to it and change the setting in your display to use dual monitor.

A couple of things here:

1) The flashing light and signal message indicate that the monitor is functioning but is not receiving a signal from the computer.

2) The memory that you added is liklely to be incompatible with the computer itself and is preventing the system from booting. The computer will perform a selftest when powered on. Normally when there is a memory issue, the unit will beep. In some cases, there will be no action.

Remove the added memory and attempt to boot the system. If it starts up OK, then the memory you have added is the problem.

Update this if you require additional assistance.

Thanks,
Dan

Tough. Have you thought of using a usb projector?
