On Screen Display gone haywire

[mrK]

here is my problem: the onscreen display of my monitor had gone haywire, that is, it started to change the monitor settings on by itself..also, i could not counteract this because pressing the buttons in my monitor (which supposedly made the OSD appear) had no effect.

here is a video i recorded about the phenomenon

The sharpness of your video is pretty bad, so I can't really see much.
What is that bar in the middle, and jumping green squares/
Does it happen at booting?

[mrK]

Sorry about the sharpness of the video.
Here is another video, a 'sharper' one.

The green one simply means that a setting was selected
and can be modified.  So what happens is that many of the
settings are modified with me doing nothing, (it just goes on
it own).  It especially bugs me when the image setup is altered
(the v-size and h-size, the zoom level, etc.).

This happens as long as the monitor is turned on.

Honestly, I've never seen anything like that before.
Same thing in Safe Mode?

[mrK]

I've never tried to boot in safe mode. So I'll try.
I'll reply after doing so. Thanks for the persistence
in answering me. 

[mrK]

Even on safe mode it happens.
Apparently, it happens whenever the monitor is turned on.

Do you have Windows CD?

That appears to be the on screen display that's built into the monitor.  I've never known an operating system to interact with it.  Have the buttons on your monitor been damaged? 

(That video is excellent for troubleshooting your issue, by the way!)

[mrK]

No real cd.  And the monitor buttons have no damage either. I wonder what's going on.

Tried the monitor on another machine ? ?

My guess as to what may be happening here is a bad cold solder joint on the board close to the pots for the monitor buttons and when the unit heats up and the contact expands it's causing the above...
Generally speaking monitors are like Bic lighters...when they run out of gas you throw them out and get a new one. They're usually too expensive to be repaired.
