Depending on the configuration,if you have installed a video card,and if it has a dvi connection thats the one to use, by default once a vedeo card is installed it automatically disables the onboard card which may have the blue connector,so the answer is once you have a dvi connector on the backside thats what you should use

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

Hi,
no worries, any monitor you buy now which is an LCD has both inputs DVI and VGA. However, it might not necessarily provide both cables. I suggest you buy one where both cables are included.
From the description, the cable you have is VGA. The VGA PC interface for it should be smooth with small holes in it. The DVI PC interface is wider than VGA

See which one you have. There are VGA to DVI adapters you can purchase in case the computer output is different form the monitor input.

Help Adding a 2nd Monitor to ALL-IN-ONE

Try using a VGA to VGA cable or a dvi to dvi cable because dvi-d and hdmi tend to lack the necessary pins to be converted to an analogue signal. A hdmi to dvi cable may also work

I need to connect a VGA dell monitor my Toshiba Laptop

HDMI is digital
VGA (the 15 pin connector) is analog.
If your connector has the digital to analog interface it should work, but likely it does not have that chip and thus will not work.

Your description of the problem tells me it may never work as you have it connected. Possibly it might be that the monitor is required to be powered on before the laptop is booted, but that only works in some cases.

I have also seen some work if a 2-step connector is used.
VGA to DVI connector, followed by DVI to HDMI connector.
DVI was the step toward digital that came before the HDMI standard was implemented and was only partially digital. DVI and VGA do not carry control signals nor audio. HDMI carries both those as well as the video.

YMMV but I think it would be cheaper and more efficient to actually purchase a monitor with a digital input (HDMI or DVI).
Without the digital/analog converter interface a digital output device (your laptop with HDMI out) can never operate an analog device (your Dell monitor with VGA input).

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,

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

Hi,

I believe you are referring to a DVi connector. We have different types of connectors but none of them is DFi. We have VGA, HDMI, SATA, and DVi connectors. Here's a cheklist of what you need to do:
  1. Check the connector of the computer whether you have VGA, HDMI, SATA, or DVi
  2. Check the connector of the monitor whether you have VGA, HDMI, SATA, or DVi
  3. Now that you know the type of connectors you have for your system, you know what cable to buy.
It does not really matter if your computer and monitor have different connectors. We can purchase cables with VGA - VGA, HDMI - HDMI, DVi - DVi, VGA - HDMI, VGA - DVi, HDMI - DVi. So, don't worry and thank you for choosing FixYa!

Dell C521 Where to connect monitor?

This means that you have an external video card (which is not outside the computer). This video card will be plugged into the motherboard. That message is saying that the port on the back of the computer that your monitor is plugged into is the wrong one. You need to look for another port on the back of the computer.

Here is a picture of a VGA port that you should use if you have a VGA cable to connect the monitor (Blue Ends).
http://news.softpedia.com/images/reviews/large/VGA.jpg

Here is a picture of a DVI port that you should use if you have a DVI cable to connect the monitor (White Ends).
http://zedomax.com/blog/wp-content/uploads/2008/09/dvi.jpg

So depending on the cable and connections that are available on your computer and your monitor depends on what you have to use. I hope that wasn't too confusing. Let me know if you need more info.

Dell 410XPs + Dell 3007WFP monitor issues

Vinod,
That's quite strange as during system startup you should see the Dell POST logo as at that point the card is only running at VGA, and the monitor will support display at this resolution. If you connect with a normal single DVI cable the monitor should display at 1280x800 also.
Have you tried this? Also have you had this monitor working on another computer at all? What happens if you power up the 3007 with no video cable connected? It should cycle through the pixel test screens. If you are not getting that, and you are not getting the pre POST logo during powerup i suspect that it is a screen failure.
Not finding what you are looking for?
