I've had this NEX MultiSync LCD1760V monitor for a good 6-7 years and it has not failed me since last week.
It's been in the same position in the same environment for 5 years (i moved).
Last week, I turned the computer on and noticed a general shaking.
It has been getting worse as the days go by.
A small portion of the top of the screen is cut off with minor white lines and shaking, and is showing up on the bottom of the screen.
The shaking, however, is minor in a black background and during startup/shutting down.

I'm wondering if this is a symptom of monitor failure, or something related to the graphics card/driver/etc.

Please help, because the shaking is bad for my eyes, yet I cannot replace the monitor anytime soon.

(Also, print screen shows the perfect image without the shaking)

Anything nearby that might be causing interference?
In the beginning there was the command line.

It's an LCD screen and has been in it's environment (speakers and printers) for a long long time.
It just suddenly started shaking one day.

It should. The problem lies within your monitor and not the video input.
I'm guessing it's a sign of failure. :thumbsup:

The fact that print screen capture is unaffected does point towards the monitor, although the video card's output circuitry after the frame buffer could also cause the problem.

The best way to be certain is to try the monitor on another computer, or connect another monitor in place of the NEC.

I expect it's likely the monitor, and first guess for a likely cause is failing electrolytic capacitors. This is very common and your description is certainly like symptoms I've seen in numerous monitors with bad capacitors. If this is the problem, it's not a difficult repair, but with the low cost of monitors these days, having it done professionally can seem expensive by comparison.
