At my current job I am using an older computer (Windows ME era so to speak). it Currently has Windows XP home and a Nvidia Vanta card. The problem is possibly not monitor related as I have tried two different CRT's. The only words I can use to describe this is "stretch ghosting" or "shadowing" as my IT experience is very limited.
Here is a screen cap of the visual bug: Any ideas?

Re: CRT Monitor and
The pot (variable resistor / preset on the circuit board inside the monitor) in the horizontal sync section needs cleaning, replacing & adjusting. but before that try the horizontal adj on the front panel of the monitor. Every monitor (digital or analogue) has it. Only if it doesn't clear the problem, try opening the monitor. Be careful so as not o venture too close to the EHT transformer.
Also make sure to degauze the CRT by earthing it (after switching it OFF) before toching any components inside. Also when you adjust the preset, make sure to use a highly insulated flat screw driver and wear heavily insulated rubber / PVC soled shoes because you'll have to adjust it with the monitor Powered ONonly then you'll be able to see the results. For your convenience, put a mirror in front of your monitor when you adjust the preset on the circuit board. Also make sure that you don't turn the preset very fast or put excess pressure on it as it may brea causing further damage to the circuit board.

It sounds like a driver/software issue. When you ran the Princeton VL173 on XP you probably had all the correct software for your video card and the correct drivers to support your video output. When you changes OS to Windows 7, the XP drivers are no longer in place. My best guess is that you need to find and install the correct drivers for your system video and for your video card that are Windows 7 compatible. The old XP drivers will not work in Windows 7.
I am running XP with a Princeton VL173. It works great. I identified the correct video drivers for my system and installed them. My video card is nVidia 8800GT. I downloaded and installed the latest software from nVidia and installed it. It runs like a champ.
Several months ago my display died. It was just blank -- black. I tried using a power supply (AC adapter) from an old HP printer that died, and it worked! The plugs were identical, and the power output profiles were very nearly identical. It has been rinnung great for many months now.
Lower the resolution on the computer to 800 x 600 and then hook up that monitor see if it at least accepts that and doesn't go black. You may have to go into safe mode to do it plus then go back into regular mode.
Go into your "Device Manager" in Windows and find out if your HDTV monitor is still installed. Delete the settings under the monitor tab and reboot the computer. With any luck the reboot will cause Windows to re-detect your current monitor and install the proper settings. A similar process may need to be followed with your video card driver as well. CAUTION: Make sure you have a disk or some means of installing a copy of your video card driver before you delete out the currently installed one.

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"
Look the problem it may not your monitor it's your windows XP.
Let me guess you have a VGA/Svideo card. From prior experience I can tell you that dual output Nvidia cards will default to Svideo first, and then "adjust" your windows settings to do so every time even if a VGA monitor is re-connected (HIGHLY ANNOYING).
So if the last thing you see before nothing is the Windows XP boot screen, here's how to fix it.
Boot to safe mode
uninstall your video driver, reboot then reinstall.
You can substitute a system restore for uninstalling your drivers if you can remember when the monitor was last working.
This really really pissed me off when it happened to me.
