Question about NEC Computers & Internet
We have two NEC 2190UPX monitors which are used for split view ( that is window is spread across both screens) from a remote work station. My wife works at home and will be working between two locations We need to set up the NEC monitor as the prime in each location and use another Mfg. monitor as the secondary at each location. However when I try to connect a different monitor in place of the secondary NEC monitor, I cant get a picture. I have tried two different monitors in the secondary position without results. The monitors are not connected together, instead each is connected to her laptop. The prime monitor is connected to the laptop. Input to this monitor is using the DVI-D and the cable is connected to the DVI of the laptop. Both connections use a DVI having only the long slot pin without 4 pins around it. The secondary monitor uses a cable with a Vega connection to laptop and a DVI connector to the monitor. However this DVI connection uses a Dvi with 4 pins surrounding the long slot pin. I have tried other monitors with both style DVI connections and have also tried replacing the prime monitor with either of my other monitors and still no picture. Both my other monitors have both VGA and DVI ports.I don't understand this. I also don't understand the difference between the two style DVI connectors some with the extra 4 pins and the ones without the 4 pins. The only thing differant is the monitors I am trying to replace the seconary NEC monitor with are not 21.5 in monitors one is larger and one is smaller however they both have DVI input connectors. I am at a loss Any help please Right now I am using the laptop with two NEC 2190UPX monitors and accessing the remote work station. The reason for this question is that I want to setup another office and was hoping to be able to use some monitors I already have for secondary monitors each Since both monitors are connected to the laptop and not each other I would expect any monitor would work as a secondary monitor since they are just reading the laptop video output. I guess I am missing something Or is there something more special about these monitors . Am I beating the bushes and need to use only NEC 2190upx monitors Any information about this would be appreciated,

SOURCE: 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.

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.
For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.
The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).
If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

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

If the monitor has two video inputs - a DVI-D and a DSub VGA then the monitor needs to be switched to the DVI-D video input.
