DVI cable not working

Hello! I recently bought an Acer 22inch lcd monitor and had to purchase a dvi to vga adapter. Everything fit the adapter ok, but when I tried to turn the monitor on I get a no signal and it goes to sleep. The vga cable worked fine. I have an HP pc, about 4 years old. Do I need a video card? and if so is it worth it just to use the dvi cable? If a new video card isnt required, any other possibilities?

If you still have your old monitor plug it back in for a bit and load the drivers for the new monitor (from the disk which came with the new monitor). Right click on your desktop and choose properties and set your display resolution to something like 1024 x 768. Shut down the pc and connect your new monitor to it with the dvi adapter. If it is recognised ok you can then set the resolution from 1024 x 768 to the recommended amount for your new screen. The refresh rate is also important as some lcd screens only work at a certain level. There should be an auto switch on the monitor and if you press this it sets the display to optimum, - or should do.

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?

Missing adapter or plug in connection to 15 balance mointor model 2015


The Balance CM2015 monitor uses a VGA connector,

http://www.ebay.com/ctg/Balance-CM2015-15-LCD-Monitor-Black-/52125929

(The above is for reference only. Not advertising)

A VGA connector is also referred to as a 15-pin D-Sub connector,

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

This is information on a DVI cable, and DVI connector,

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

If this is the monitor cable you have, you need this type of adapter,

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

Now LOOK closely.
This adapter has male pins that stick out, and go into a female VGA connector on the monitor. The DVI side of this adapter has socket holes, for a male DVI cable.

IF, your monitor has a male VGA connector on it, and the DVI cable you have has socket holes, you need this adapter,

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

If your monitor cable is not a DVI cable, post back with the style it is.
If nothing else post how many pins are in the connector on the cable, and how they are arranged.

For additional questions please post in a Comment.

I have a dell dimension 3000, bought a new HP 2310E monitor with 3 ports. DVI, HDMI & display port. Told to buy a cable with VGA to connect to dell and DVI to connect to HP Monitor display port....


Hi sshorne9780,

I see that you are having a check input error on the Monitor/LCD that your are connecting to your Dell tower, please see steps below.

  • On your HP 2310E make sure that your HP is set to the input/source that you are using and make sure that you only use one type of video cable for the issue.
  • I see that you mentioned that you have a VGA cable and a DVI cable, you can only use one type of cable for a video connection.
  • VGA would be the Blue tipped cable connecting to the tower and going to the LCD monitor.
  • DVI this is a black cable connecting to a white port much bigger than a VGA port and is rectangular in shape unlike the VGA
  • moz-screenshot.pngmvincentc_34.jpg
  • and on your LCD monitor check the input type to see video from the tower.
  • everything seems to be OK you just need to change the input of your LCD monitor for the video to show up on the screen.
  • also if you are using HDMI for the video u will need to change the setting of your Audio and set HDMI as the Default to have Audio come out from the HDMI connection together with video, the HDMI viedo will automatically be detected as long as the LCD monitor's input is set to HDMI.
I hope that this will able to help resolve your concern.

Thank you for choosing Fixya,

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

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

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

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

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

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

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

Changing cable port


The monitor is a Fujitsu VL-15DX5G. 15 inch LCD.

The monitor cable uses a female DFP20 connector.
(Display Port 20-pin)

http://auction.thumbnail.image.rakuten.co.jp/@0_auc/image50/cb/4a/00010523850/a1/85/img00149858603.jpg

So you need a male DFP20 to male DVI-D adapter, or adapter cable.

DFP20 Male to plug into the monitor cable, and Male DVI-D (Dual) to plug into the graphics card's, female DVI-D connection.

So far, all I have found from a quick search is a Male DFP20 to Female DVI-D adapter, such as this example,

http://www.worldofcables.com/store/viewitem.asp?idproduct=768

Of course this won't do.

IF, this is all that's available for DFP20 adapters, you'll need an adapter of Male DVI-D to Male DVI-D, also. (Yes, I am aware of how crazy that sounds)

(It would appear, adapters are sold to connect a normal DVI-D monitor cable, {Male}, to a computer with a female DFP20 connector)

Should your searching only find DVI-D female to DFP20 male adapters, or adapter cables, then here is an example of a DVI-D male to DVI-D male adapter,

http://www.kvconnection.com/product-p/m-sgc-dvid-mm.htm

(DVI-D male to DVI-D male cable would probably be better as there would be less strain on the graphics card's DVI-D connection)

Most of the Widescreen monitors come with DVI as well as VGA connector. A VGA connector and DVI connectors are different in many aspects. First of all the DVI connector would be white in color and VGA would be blue.
VGA connector has 15 pins and DVI has 24 +1 pin

I have just installed a Acer LCD #X223W moniter. What do I need to do to get my speakers to work with it? Is there a missing port or do I need a new cable. This moniter has a HDVi cable but the Computer...


Did you give the correct model of the Acer monitor you have?

When I looked up the X223W monitor, I see a monitor with a DVI-D port and VGA port. Only the VGA cable is usually included in the box. If your computer has a VGA port (most older computers that came with only the video chip on the motherboard), you can either use the VGA cable or get a VGA to DVI adapter and use a DVI-D cable (purchase separately). Alternatively, check the specs of your power supply and available card slots and buy a new video card with a DVI port. If you have only a DVI port on your computer, get the DVI cable (the VGA to DVI adapter would work but isn't a good option).

If I read the specs correctly, this monitor doesn't have speakers. You should plug your speakers into the audio out of your computer. If you use the on-board audio you will see at least two jacks (microphone/line in) and audio out (speakers). Many audio cards and some motherboards come with additional jacks for surround sound so check your system information. Audio extension cables are a cheap solution if the speaker cables are too short to reach to your computer.

I hope this helps.
