I have a Dell Inspiron 531S, I have both two different monitor slot, does my PC support dual monitor systems?


Yes.

The area on the back of the computer, that has two ports to connect a monitor, is a Graphics Card.

It is a PCI-Express graphics card, and is plugged into a PCI-Express x16 slot on the motherboard.
(Expansion Slot)

It has a blue VGA port, white DVI port, and black S-Video port.

The area on the upper left with a blue outline around a VGA port, is a VGA port connected directly to the motherboard. It is Integrated Graphics.

You CANNOT use Integrated Graphics, and a graphics card at the same time.

It's either use the Integrated Graphics VGA port, OR use the graphics port/s on the graphics card.
BIOS will Not support using both Integrated Graphics, and a graphics card.

HOWEVER, you can use the VGA port, and the DVI port when using two monitors.
You will be only using just the graphics card.

Example of a VGA port, (Connector), and VGA cable,

http://en.wikipedia.org/wiki/VGA_connector

Example of a DVI port, and DVI cable,

http://en.wikipedia.org/wiki/DVI_connector


1) Whatever monitor you have that has a VGA cable, plug it into the blue VGA port on the graphics card.

(There are VGA monitors {CRT} that resemble a small TV. VGA cable is usually attached.
There are also LCD flat screens that have a VGA connector, for a VGA cable, and may also have both a VGA, and a DVI connector.

To digress for a moment;
VGA is Analog. It uses an Analog video signal.
DVI is digital. It uses a Digital video signal.

A computer naturally puts out a digital video signal. This digital signal has to be converted by the computer, into analog for an analog monitor. This slows the graphics process down. This is one reason it is best to use digital )

2) Plug a monitor with a DVI cable into the white DVI port on the graphics card.

3) Turn the monitors on.

4) Turn the Inspiron 531s on.

5) When Windows has loaded, right-click on an empty area of your desktop computer screen.
Now left-click on Properties at the bottom of the list.
Left-click on the Settings tab.

6) You are now looking at a small window that has two monitor icons in it.
Monitor 1 icon, and monitor 2 icon.

Monitor 1 icon is your Primary Display.
Monitor 2 icon will be for the Secondary Display you are adding.

Note how monitor 1 icon is sitting to the Left, and monitor icon 2 is sitting to the Right.
This is how your monitors are supposed to be arranged on your computer desk.

If the second monitor is on the Left on your computer desk, you need to move the icons around.
Move monitor 2 icon to the Left.

Left-click on the icon, hold the left mouse key down, and drag the monitor 2 icon over to the left side of monitor 1 icon. (All the way over, or it will snap back to where it was)

It may matter to you how your monitors are arranged. It may not. Once you read the following it may help you decide.

7) Left-click on monitor icon 2 if you have not already done so.
Go down to where it states, "Extend my Windows desktop onto this monitor"

8) Left-click once in the empty square, to the left of Extend my Windows desktop onto this monitor.

9) Now left-click on Apply at the bottom Right corner.

10) Finally left-click on OK at the bottom Left corner.

You should now see your desktop screen on both monitors.

When using the internet on both monitors, you have to drag the screen from the Primary monitor to the Secondary monitor.

Go to the left side of the screen. Left-click right on the edge of the blue frame. Hold the left mouse key down after you click, and drag the screen across to the left.

Doesn't work?
Go to the right side, click on the blue frame, and drag the screen to the right.

This is why it may matter how the monitors are arranged on your computer desk.

It's kind of eerie your first time dragging the screen across.

You will also find out why it is best to use two similar monitors, when using dual monitors. The pixel resolution is different for both monitors, if they are different from each other.

I have a 47 inch phillips hdtv and a hp elite cpu the hp eliute has a blue ray player there hooked up though a hdmi cord the tv starts up windows and shows safemode but when it goes to the password screen...


tv starts up windows and shows safe-mode. That right there is your problem, windows defaults the monitor down to regular 640 mode. I will cut out the hdmi since that is not a monitor. Safe-mode is used to trouble shoot your computer and it loads just barely the drivers you need to see and work with the computer. You will have to get the computer to boot up normally then proceed from there, also you will have to set up your video card to output hdmi.

You probably have a mismatch between the two devices relative to resolution. Check both to make sure that you are not asking the TV to do something that your normal monitor can accommodate. The Windows logo is normally drawn in the default VGA resolution of 640X480 or 600X800.
If you are using the common computer monitor resolution of 1024X768 your TV may not be able to sync to this.

How can we connect two moniters to one cpu


To have and use 2 monitors at the same time, you need a video card with a dual VGA outputs.

To use 1 monitor at the time you can buy a VGA switcher, to switch between the 2 monitors.

Computer works for a bit then the whole screen turns to pixels. we bought this pc brand new about 3 months later started showing images pixel up, noe the whole screen turns to pixels..and cant see nothing...


Well, the first thing you can try is replacing the monitor cable or monitor, and that is less expensive. If it still gives you trouble, you may need to see about replacing the video card; there are modestly priced, reliable ones that are relatively easy to install, yourself. I'd recommend installing the new VC after taking out the old one, just because your system will be happier. Then see if after any of these steps, the monitor isn't working better.
If it still presents a problem, it may be an issue with the motherboard, which means basically replacing the whole system, for the cost and time involved, depending on your motherboard.

Monitor Shows pixelated colors then flashes no input and turnsoff


Well the fact that your computer beeped tells me that there was a fault in either the motherboard or the video card. I would first replace the video card.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

PC bootup problem


Double check your connections ( the cord between monitor and computer{usually has blue ends}, they always wiggle lose) . If that doesnt fix it, buy a new cord and check for video card updates.

Possibly Video Card problem?


Mikolan,

That is so crazy.
You say you previously was able to see the POST screen and now you can't?
You say you switched monitors and card outputs to no avail? Is the card an ATI with an aux Molex power connector?
Is the puter actually going into standby or hibernation?
Have a boot disk? or a PE?
How about a Linux self-install distibution CD. Just kidding about that last one. Not really, you can see if the puter does respond.

Don't rule out a faulty power supply. Video card fail is usually one long, two short beeps at POST. or 8 short.
