vertical lines

[bob]

Hi all,

I found many vertical lines on the desktop monitor even I swap with another
monitor. It is many thin lines although I can still use the monitor but it
do not look good. It seems to be display problem but I cannot fix it by
re-plug the display card or re-install the driver. Any idea ?

thanks

found on windows graphic.

Try changing the resolution, and see if the lines go away.
