Why does my display "Jump" approximately every 3 to 4 seconds?

Check the cable the jumping could be cause by poor cable connections check to see if something around your desk is providing a high amount of electrical noise for example, you may be able to stop the jumping by moving the desk fan to a different outlet your speakers or fluorescent lights placed to close to each other might cause interference try moving your monitor to an altogether different location also try a different refreesh rate if your monitor supports it.
