Non display for DELL GX 110PC Desktop


Either your monitor is bad or the video card inside the computer is bad. To isolate the problem try a different monitor on the computer. Borrow a monitor from a neighbor, friend, relative or co-worker. If the borrowed monitor works, then your original monitor is bad. If the Borrowed monitor does not work, then the video card inside your computer is bad.

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.

For additional questions please post in a Comment.

My Sony Vaio PCV J100 turns on but no nothing comes on the screen/monitor. I have checked the monitor but it works fine on other computers. What could be the problem?


If your monitor works fine on another computer then most possibly its your video card since you said nothing comes on. Usually if its the operating system you should see the computer info before it goes to a blank screen. If you have an add on video card try using the integrated video card or vise versa. You can also use a known good video card from another computer.

Monitor comes on then turns itself off yet power switch remains lit. email popluck18@windstream.net


First, check all connections carefully.

Have you reinstalled the monitor using the disk that came with the system?
Try getting off the internet and turning off your virus control before installation. Also, make sure there are not a lot of programs running in the background. You can check what is running by right clicking on your desktop. You can unclick anything that has nothing to do with the system or windows, such as programs that you have installed etc. You can go back afterwards and recheck them, for immediate startup.

I hope this helps.

WHAT IS VB.NET?


Visual Basic .NET (VB.NET) is an object-oriented computer programming language that can be viewed as an evolution of Microsoft's Visual Basic (VB) which is generally implemented on the Microsoft .NET Framework. It is a competing technology to Sun's (now Oracle's) Java 2 Enterprise Edition framework.

I have a dell Dimension 2300 and the images are very dark. I don't think it is from the monitor.


Try these steps: 1. Check the monitor settings. Access the On Screen Display (OSD) Menu System. Adjust the contrast and brightness using the control buttons in the monitor.
2. Run the monitor self test. Unplug the video cable from the computer (cable from monitor to the back of the computer). Usually it has a blue or white connector. Turn on the monitor alone. It should display the self test pattern (white, red, green & blue). If the images are dark in the self test, it is a problem with the monitor.
2. Rotate the monitor to face a different direction. This will help in eliminating sunlight glare which can cause poor picture quality.
3. Test your computer using another working monitor. If the problem occurs in a known good monitor, then it is a video card or motherboard (if your video card is integrated) problem.
I hope these options help.

My computer monitor was disabled so now it is black is there any way to reset it or enable the monitor?


Alyssa,
Two ways:
1. Power On the computer and get into the BIOS settings screen. The monitor will turn ON and allow you to view the menus. Select the integrated peripherals menu and set the "use internal vga" ON.

2. If your computer has a add-on video card, unplug the monitor cable from the internal monitor interface and connect it to the add-on video interface.

How do I do about resetting the bios to see if my monitor issue is the graphics card that is causing the problem?


Hey Hi Mary,

Well if your system has an EXPANSION GRAPHIC CARD then in order to find out if the GRAPHIC CARD has gone bad u actually need to remove it from the system then hook up the monitor in the INTEGRATED VIDEO PORT. If the monitor works well and good then its the GRAPHIC CARD which has gone bad.

Because until the GRAPHIC CARD is installed in the system the system by default keep ignoring the INTEGRATED GRAPHIC CARD it will not even detect whether the system has an INTEGRATED GRAPHIC CARD or not..

Kindly Reply Back If You Need Any Help..
