My friend's Pc monitor is trembling like when using a cellphone near the monitor. The UPS is far from the monitor that means it cannot be the UPS. The PC and the monitor are getting power from a n extension with two cable only (without the hearth one). and the extension is connected to the UPS. what could be the problem?

It's called radio interference - most monitors are shielded to some extent, but a close source will show the symptoms you describe.  Keep unshielded speakers away also, or you will suffer from magnetic interference, which is more permanent.

Try Hitting the Deguass button on the front of the monitor it releases any magnetic interference .

It is also possible that the interference is coming from a metal stud or something else in the wall.  I had this happen once and we moved the computer desk to the opposite side of the room.  All was well after the move.
It could also be reduced (I believe) by lowering the resolution used.  If it is at 1024x768 try 800x600.
Can you try a different video card?

Try changing the refresh rate.  I have seen old monitors just not like refresh rates other than 60hz.  
Also like Slink9 said, change the resolution.

cell signals are too hard and the megnatic field can distrub the fosforus of the monitor. not keep your cell away from the monitor.

callandor is right - you will not cure this problem,
this is not a monitor or computer problem

RF broadcasts interfer with monitors, TV signals, other radios
just don't use cell phones or other RF devices around them

Some negative feedback should be appropriate if he doesn't come back - he's already started in that direction.

The monitor trembles most when using Microsoft Word 2002 could it be the source of the problem.

I believe I see some negative feedback from Callandor.  I guess that should be expected when the answer accepted starts off with "Callandor is right ..."

chriska,

Any reason for choosing the answer you did, since it isn't different from mine?
