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.

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

Unless there is simply some dirt or dust caught in it, I would imagine that the button has lost its 'spring' or bounce-back ability which means that either you can take the big risk of attempting to fix it or come up with some other clever way to give it bounce.

After you've checked that the video cable is connected properly, make sure that all the pins in the video cable plugs are straight and not broken off. Then test on another PC. Make sure your CMOS battery has not gone flat, as some PC's will fail to load basic drivers if CMOS memory is lost. The battery should show no less than 2.5v, if it's marked 3 volts when tested on a multimeter. If you can't test it, just buy a new one at the supermarket or hardware, usually around $4.00.
Next thing to try is your Video Card . If it is an on board one like most are now, there isn't anything you can do but try another card in an expansion slot or fit a new motherboard. At this point, I'm sad to say, you're better taking it to a PC shop where they will have a few things at their disposal to try.

The cases these days are hard to open, they use plastic finger hooks types, they go in easy but real hard to remove without damageing them.
Use thin flat blade to crack open at the bottom edge so the scratches will not be so noticeable, and work your way around, look out for cables attached to the front bezel also.
