Question about NEC MultiSync 1760NX 17" LCD Monitor

1 Answer

Help Please! I am getting a "dvi digital no signal video input" message on my monitor and then it goes black. I have replaced the video card and still have the problem. My DVD drives no longer open as well. Are these related issues or two separate issues? Any suggestions on the cause of either problem? Could someone explain what the dvi digital no signal ...message means? The monitor works on another computer so I know it is not the monitor. I have also replaced the cables to the monitor.

Power supply is bad on one of its legs(12 volt or 5 volt) you can have that bench tested at a service center or use a volt meter to check the output on the cables probably the 5 volt as the agp and the dvd roms cdroms etc need 5 volts to operate

My monitor(HPL1950) was working good until i unplugged it to play on PS3. When i connected the monitor to my PS3 with HDMI it showed black screen. I cant figure out what is wrong with it


I assume you have never tried this option before. Based upon the manual for your device, it seems that you may have a compatibility issue. SOME models of your device had digital video input capability. But most operate on analog inputs only. Even the DVI jack (which ironically stands for Digital Visual Interface) on most older devices is an ANALOG input jack. Only when you get to DVI-D and DVI-DD does the input get totally digital. So what you are probably seeing is that the monitor see a signal on the DVI, but cannot comprehend it as it is looking for an analog video signal and is receiving a digital one. Here is a Wikipedia Link explaining the different DVI jacks, their capabilities and limitations.

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.

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.

Power drain


There is a lack of communication between the monitor and video card. Try reseating if add-on video card. Make sure monitor is set to correct input, like VGA (analog), DVI, HDMI, or Display Port. Try testing with another monitor.

The problem might be with your ram. Try taking it out and putting it back in. You might also have a problem with the video card. Make sure it is secure and screwed in.

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.

Please check whether you are using a DVI (Digital Visual Interface) cable or VGA (Video Graphics Array) cable to the monitor.The monitor will adjust automatically to the requirements of the connected cable.From the question I think you had connected a DVI cable to the monitor.Make sure that there is no loose contact between the ports and the cable.Also make sure that the proper settings on the monitor are done for the DVI cable configuration.

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.

"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
