LCD monitors do not need degaussing. They operate in a completely way to CRT monitors.
Tiny black marks are most likely dead pixels, if the black marks are large then the LCD screen may be damaged (cracked glass).
This type of damage cannot be repaired simply, the screen needs to be replaced.
I suggest you put your money towards a new LCD monitor.
I'm currently having the same issue, but after some research I have found that it may be that your video cable is disconnected or damage. I hope this helps.
This problem often occurs in samsung SyncMaster LCD monitors.
The
solution is open your look for the LCD monitor power supply module
(which have PCB connector to the AC power), on that board look for
capacitors, now look for broken one which upper part is bloated, like
the image below: If you find a damaged capacitor as in the picture then you should replace it with the same value.
The thin ribbon that connects the board on the back of the lcd screen to the front glass of the lcd screen got damaged.
It wraps around the top of the screen and is very thin and can be easily damaged.
May be from old age and heat at the top of the screen or it could have gotten hit at the top.
If you keep pushing it in and out you may damage another one and make another line.
The cheapest way to repair this is to replace the lcd screen with a
good used one because trying to find a shop to try to repair it would
cost more than a new monitor.
Sorry there isn't an easy fix to this.

well in order to get rid of the self test window from your monitor... check the cable that connects your monitor to system tower & reset the connection... becase that is the only possible cause of the self test showing up on your monitor...
" as the self test option only appears when there is no video signal going from your video card to the monitor...
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
This box also appears during normal system operation if the video cable becomes disconnected or damaged.
Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
