The latter part of this post seems to confirm that the problem is inside the monitor, probably a failure on the signal / video board. You might also look for damage to one of the connectors. Otherwise, if your manual shows some settings or a rest, that might be the issue. But the fact that the self-test does not work leads me to believe that the unit needs a new a signal / video board.

How to switch from analog to digital mode

Any contemporary monitor is able to switch analog/digital mode automatically if connection from signal source to monitor is set up properly.

Connect digital output from your graphic card to DVI input of the monitor. Disconnect any other signal cables from monitor and switch on both devices (PC & monitor). Wait a while. Monitor checks its inputs and a activates digital DVI, because it is only one active input on it.

If none picture excluding error message of monitor is displayed, go through these steps:
1) Check whether your monitor is set for automatic input selection. If monitor buttons have no response try to use analog input to activate screen (any picture, desktop background...) and then get monitor menu access by pressing menu button.

2) Find out what connector type has your graphics card in PC. Possibilities are: DVI, HDMI, DisplayPort and some their options. See Wikipedia for connector look if you are not sure.
Remember that blue D-SUB (VGA) connectors are analogue and you cannot activate digital mode through analog VGA cable.

3) Use appropriate cable to connect monitor to PC.
Example: Your PC has HDMI output. Use HDMi-to-DVI cable. Your monitor input is DVI and common DVI-DVI cable is not suitable in case you have PC with the HDMI.
Note that DVI-to-DVI, DisplayPort-to-DVI etc. cables are available. You must buy right one.

Be aware that "Auto" button is inactive in digital mode of monitor.

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 cannot hear any sound from my Dell monitor 1702FP. Are there speakers installed within the monitor?. VGA cable is connected. When I use a spare monitor using the VGA cable the sound is loud and clear. ...

The Dell 1702FP doesn't have speakers.The specs of the Dell 1702FP are available here: http://support.dell.com/support/edocs/monitors/1702fp/en/specs.htm . (BTW neither does the Dell 1704FPT.) However, some Dell monitors can have a sound bar (speaker set-up) mounted on the monitor.

VGA cables don't carry sound. Check if a second cable (an audio patch cable is connected to the computer and the second monitor). (There are some cables that actually bundle the 3.5 mm patch cable with the video cable for convenience. (I've seen a number of DVI cables with that bundle option.) The plugs will separate into separate units at each end.

Other monitors do have speakers built in - look for a 3.5 mm audio input jack with the rest of the input connections on your monitor. There are some monitors that accept an HDMI input with a 3.5 mm audio out jack; these monitors don't have speakers and thus are enabling a daisy chain to connect the speakers to the monitor. So you do need to be careful and look for the audio in label.

You can attach a set of speakers to your computer using the audio out (look for a lime green 3.5 mm jack on the back of a desktop). For laptops or to use the front audio ports, look for a headphone jack.

I hope this helps. Please add a comment with more information about your monitor and computer for additional assistance.

I have a nVidia Quadro2 MXR/EX video card which works fine on the analog input but when you use the digital input the screen sometimes flashed at startup and then goes blank. If you move the mouse,...

There are a few things that come to mind here. Number one is to try a different and known functioning DVI cable. Maybe see if you can recreate the problem simply by wiggling the dvi cable. If there are any splitters/adapters, remove them and plug the cable straight from the video card to the display. Make sure the display is set to digital input mode. When you are using the digital cable, make sure to completely remove the analog cable. See if this problem happens outside the operating system (such as in the system bios, if it does, this indicates a hardware issue). Finally, the digital input on the monitor could be having an issue, try a different monitor or try this monitor with digital input from another system.

If you add a DVI adapter to the the DVI cable going to the Dell Inspiron 580 VGA input, do you get true DVI quality? Can you use a DVI to HDMI adpater?

For the best results, you a straight DVI cable.

VGA is analog, while DVI is digital. The quality will not be as good a a regular DVI cable.

You can use a DVI to HDMI.

I use one going from my PC to TV and the quality is awesome.

Dell228wfp on start up pwr on is green screen

Either the cable is not connected to the proper port or the display-source is not configured properly.Here's what you can try.
  • Ensure that you have connected the VGA/DVI cable in the correct port. If you have an extended graphics card in your computer, use a DVI cable(Digital input) else the VGA would be the only option available.
  • If the cable seems to be plugged at the right place, press the first button from the left on the front panel of your monitor (Button 1 shown in the front view: http://support.dell.com/support/edocs/monitors/E228WFP/En/ug/about.htm#Front_View), once. This toggles the digital mode to analog mode of your monitor, and vice versa.
  • If the first two steps do not work, its not an issue with the monitor. It could be a failing cable or a defective video card, or the system itself is not completing the POST.

Thanks,
Abhishek

VGA connection works, DVI does not

Everything seems perfectly normal...

When you connect the computer to the monitor via an analog VGA cable, you get signal on the analog input.
When you connect them via a DVI cable, you feed the monitor's DIGITAL input, so the monitor doesn't get any signal on it's analog input, and informs you about it.
You have to select the digital input from the monitor's On Screen Menu, and then start the computer up - you should see the picture OK.
Also remember to set the display resolution on your computer to match the optimum (native) resolution of your monitor - this will give you optimum picture quality. In case of VA712B it will be 1280x1024.
Good luck and please come back with a testimonial if helped.

Inoperative monitor

Here are a couple things to try.

1. try the input select button on the monitor (The minnus button) without pressing the OSD menu button 1st, see if it changes to analog.

http://support.us.dell.com/support/edocs/monitors/1703fps/en/controls.htm

When the DVI self-test screen is up, it is indicating monitor is in DVI mode.

2. If that doesn't work, try a DVI to analog converter on the DVI port on the monitor and connect the analog cable to the converter. See if you get any video that way.

3. If you can access the On-Screen Display (OSD Menu) perform a factory reset.

"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
