I agree. However to fully determine, try a known-good monitor with known-good DVI cable. If so, the bad news is you likely will need either a third-party video card or a new systemboard.

2nd monitor does not work with DVI to VGA converter cable. My video card has VGA and DVi ouputs.


The problem could be in the adapter to the video card. There are different types of DVI connections. If the adapter does not have the proper set of pins then the card will not recognize that a monitor is connected at that port. Monitors themselves have no bearing on whether a single or dual monitor set up will work or not. Digital Visual Interface Follow this link, it may help you determine if the adapter you are using is correct for the graphics card.

Can i get an adapter for my emachine monitor to go into a dell desktop ...my lead i have now doesnt fit as unable to screw it in


YES.

I believe it is time now for the guessing game............

1) Is the monitor about so high, and so wide?

2) Does the monitor look like a small TV, or is it flat in appearance?

3) What does the monitor cable look like?

4) Is your hair Brown, and do you smoke cigarettes?



NO.............just wanted to see if you were following along! Geez!



An Analog monitor, such as a CRT type of monitor, uses a VGA cable,

http://www.wisegeek.org/what-is-a-crt-monitor.htm

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

Scroll down a little for a VGA Cable example.

Flat LCD screen monitors are Digital.
Some may have a VGA Cable attached, but the best cable option is a DVI cable,

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

(Click on any photo on those two Wikipedia pages, to enlarge)

Using these two examples, does one apply to the eMachines, and one apply to the monitor?

Let us say the monitor has a DVI cable.
The eMachines Desktop PC has a VGA port. (Connector)
For this you would simply use a DVI to VGA adapter,

http://www.directron.com/dviadapter.html

Now notice...........this is a VGA MALE to DVI FEMALE.

The DVI cable on the flat LCD screen monitor, has a male connector.
The contact pins of it go into socket holes, in the DVI end, of the DVI to VGA adapter.

The VGA port on the eMachines, has socket holes.
The male VGA connector end on the DVI to VGA adapter, has contact pins.

Point?

Make sure you get the correct DVI to VGA adapter.
There is a male DVI to female VGA adapter, also.

This is just one example.
For instance I'm using an HP 2009M 20-inch widescreen monitor, AND an RCA 26-inch HDTV, as dual monitors.

Presently using the HP 2009M with a DVI cable, and the RCA L26HD31 HDTV with a VGA cable.

(I'm also using an ATI Radeon HD5450 graphics card. Pretty 'pud', but it does OK for what I want)

Primer;
A computer sends out a digital signal. To get the best graphics quality, you ideally use a monitor with a digital cable. (DVI, etc)

When you use an Analog monitor on a computer, the computer has to change the digital signal down to an Analog one.
Therefore the graphics quality is not as great.

Digital cable technology now, is DVI, HDMI, Display Port, and Mini-Display Port. And some others I'm sure I've forgotten.

http://www.hardwaresecrets.com/article/Video-Connectors-Tutorial/157

For additional questions please post in a Comment.

Also post what the monitor manufacturer name, and model number is. (Look on the back)

Are you using the VGA connector on the motherboard, (Back of computer), or do you have a graphics card installed?

If you have a graphics card installed, what is the manufacturer name, and model number?

How to add second monitor on ECS RS482-M


Doesn't work that way Max.

You can use EITHER the OnBoard Graphics,
OR;
the Add-On Card graphics. (Graphics card)

BIOS will NOT support both at the same time.

If you wish to use dual monitors, get an AGP card that has more than one graphics port on it.

For example, although I'm using a graphics card based on the PCI Express technology, and not AGP technology; my card has a VGA port, DVI port, and HDMI port.

1) VGA Connector; http://en.wikipedia.org/wiki/VGA_Connector

http://en.wikipedia.org/wiki/File:Male_VGA_connector.jpg


2) DVI; http://en.wikipedia.org/wiki/Digital_Visual_Interface

http://en.wikipedia.org/wiki/File:Dvi-cable.jpg

http://en.wikipedia.org/wiki/Digital_Visual_Interface#Connector

3) HDMI; http://en.wikipedia.org/wiki/HDMI

I use the VGA port, and the DVI port.

RCA EN-V L26HD31, (26 inch HDTV) to the VGA port.
HP 2009M 20 inch Widescreen monitor to the DVI port.

Had to install drivers for HP 2009M.

Let's say I had two DVI ports on the graphics card.
(ATI Radeon HD5450 is the graphics card I have)

But I have a monitor with a VGA cable, and a monitor with a DVI cable.
I would (And have) use a VGA to DVI Adapter.
One example,

http://www.directron.com/dvi.html

Note that the DVI is Male, and the VGA is Female.
The graphics card DVI connector is Female.
The VGA Cable connector is Male.

So.............what is the manufacturer name, and model number of the graphics card; plus what type of monitors are you trying to use?
That is, what type of monitor cables do they have?

Know this;
My HDTV I'm using as a monitor is Digital. However I'm using a VGA cable on it. Best quality would be achieved if I got off my lazy rear, and attached a DVI Cable to it. It uses both.

VGA is Analog. A computer however puts out a digital video signal.
The computer has to convert the digital video signal to an Analog one. This slows the video signal down, and the quality is not as good.

Best to use a digital monitor. (Or a digital monitor WITH a digital cable. DVI Cable. Such as I need to do)

You are also using a PCI Express graphics card, NOT an AGP graphics card.

I'm wrong? OK.

In the meantime turn the computer off, unplug from power, and yank that AGP card out of the slot you put it in.

Tell me what expansion slot on the motherboard you put it in.

The Orange expansion slot on the motherboard, is a PCI-Express x16 slot. Uses a PCI Express graphics card -> ONLY

The white expansions slots are PCI.
Can use a PCI graphics card. CANNOT use an AGP graphics card.

DVI ==> Digital Video Input
If your monitor has both DVI and VGA inputs,
and your PC's video-card has both DVI and VGA outputs,
then buy a DVI-to-DVI cable, and use it, for a better picture.
If your monitor has both DVI and VGA inputs,
and your PC's video-card only has VGA output,

Or, purchase a video-card with DVI output,
to replace the video-card with VGA output,
and then use a DVI-to-DVI cable.

Make sure your monitor is set up to recieve what ever signal you are wanting via the monitor's menu. There should be an input button on the monitor to select the signal type. The connection really doesn't matter as long as you are able to use the monitor. There could be something wrong with the connector on the video card. Also make sure you are using the card and are not using the onboard graphics connection by mistake. If the problem persists it is more than likely the card.

Monitor says No signal digital


Is ether the monitor or video card uses both DVI or VGA port. There may be a switch on the graphic card that changes it from DVI to VGA, often outside the card.

Also is the computer monitor set to the right setting if it can use both VGA and DVI, if using DVI (of any type) it need to switch to digital, and if using VGA it need to be set to analog. This may be a physical switch or using the settings button. (see manual how to change them)


PS: VGA port is a blue D shaped port with 15 pin holes, and DVI is a white rectangle port with one port being a line.

"No signal detected" when LCD connected with DVI-D Cable


Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

DVI input on monitor not working


Contacted viewsonic about this issue- they suggested- have both dvi and vga hooked up to same machine. start with poweroff on both. power on monitor, then power on computer. when you see display coming from the vga, power off pc, then disconnect vga cable, turn off power to monitor, disconnect power cord from monitor for 5 + seconds, reconnect power cord, power on monitor, then power on pc.
If this doesn't work to get the dvi working, (as happened to us) we returned our monitor for a replacement, since it was still under warranty.
