My KDS XFlat X7-Fe is losing its picture quality....

Yesterday I unhooked my KDS 17" monitor from my system and sat the cable down on the desk in order to move my system.
For some reason I heard a twing sound and I wondered what must have broke. I didn't see anything anywhere on my table. Well when I went to hook my monitor back up to my system. I noticed that PIN #5 on the monitor's SVGA plug was missing, which is very unusual.

When I turned on the monitor and the system, everything seemed fine. But for some reason the monitor displays images a little more blockier than it used to. The monitor is suppoed to have a .25 dot pitch, but now it looks like the monitor has a .28 dot pitch. The image seems little more grainy.

Could this missing pin #5 be attributed to this problem? What does pin 5 control on SVGA monitors?

Any help would be appreciated. thanks.

The pin 5 on SVGA connector must to be GROUND. If it is missing, this may cause the signal distortion, if this pin was be connected to signal line shield.

Interesting... I kind of thought it controlled something like that. However, I have searched the net for pinouts and and most of them say that pin 5 is UNUSED. Others say it is RESERVED. Thanks for your help.

Okay... I called KDS tech support and they said that the PIN 5 on the XF-7e monitor controls nothing. Not a ground or anything.

The tech support person said that the problem lies within windows.

On other news, my monitor does make a squealy sound. It always has when there was when white is displayed workspace is displayed on a maximized window. Its very odd.

My monitor is set at 85Hz (one very good setting) and its set at 32-Bit Color mode.

Well, it's similar to the high-voltage breakdown of isolation on a CRT board or somewhere in high-voltage circuits. The possible solution of a problem can be the following: it is necessary to take off a cover and to remove a dust from all contacts on a CRT board. If you have experience of similar work performance, remember, that all operations when the cover is removed are necessary for carrying out at the unplugged power cords.
The best decision (especially, if there is a guarantee period has not expired) will to visit the service center as the problem can be caused also by damage of isolation of high-voltage circuits.

That could be one solution to the problem but I do not ever want to take apart this monitor. Its not worthing risking my life or the monitor itself over. I am not a monitor repair technician. I am just a plain Joe Bloe A+ certified technician (who is soon to have an A.S. in Computer Info. Technology this December).

I think that tech support people at KDS are complete idiots. I called a local monitor repair shop and a person there said, exactly what you said about the GND and signal interference. However, they refuse to service anything made by Korean Data Systems because they only work on CRTS, not the cables or connectors. :-(

You have been very helpful and have affirmed some of the things that I have originally thought were wrong with the thing. I just know not to buy a KDS monitor again. Thank You for your assistance.
