what model of monitor do you have..?

there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

Nothing wrong with your mon. It is your windows display setting.
Go to display properties and change it back to normal.

replace the monitor: it's lost vertical scanning

the keys ctrl+alt+right arrow should do the trick for you. if not then right click on the keyboard and select properties for options and you will find your graphics software has its own rotational software. good luck with two year old, sounds like you'll need it.

Orientation can be changed to landscape mode by accessing the video card properties in the windows "Control Panel".

What Video card are you using?

WIN XP
Right click Desktop>>>Graphics Options or
Right Click Desktop>>>Properties>>Settings>>>Advance

and change the rotation to NORMAL

For Intel Video card go to GRAPHICS Properties
For ATI Video card go to CATALYST
For NVIDIA Video card go to PHYSx

I have a similar problem with a 2 year old Samsung monitor. I have tried to make a screen dump of it, but the horizontal lines do not show up then. This I have read indicates that the problem is in the monitor and not the video card.
