I have two identical monitors and a windows 8.1 system. The system intermittently recognizes the screen or not, and i often get a 'no signal', even though it is plugged in. I actualy swapped out cables and it worked occasionally, then thought it was a bad cable, but now it is not recognizing the signal with the good cable
People forgot to mention, check the current drivers installed on your computer.
Try checking you current drivers.
How to Check the Video Driver

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

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.

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
SOURCE: monitor says: no signal input check video cable .
Sounds a bit bland but either the monitor has failed or the video card
Only test is to plug your monitor into another system and see if it comes to life
If it does then your video card has expired.
If it is part of the motherboard then the easiest option is to buy a replacement which plugs into the AGP slot
They are dirt cheap unless you are into gaming when the sky's the limit

I used 2 resistor of 100 ohms (1/8W) to make one of 50 ohms. Like others instruction, just put the 50 ohms resistor between pins 5 and 6 of this chip and the problem is solved.
