Twitching display = sign of monitor or graphics card problems?
Can you try another computer (or graphics card) with your monitor? This will
determine whether it's your monitor or card. If your monitor still causes the same problem and if its not an electronic fault then it could be that some device probably nearby is 'switching' causing a magnetic field to interupt the display. I had a similar problem when I'd placed the power supply adapter for my MSFF wheel behind the monitor when I was tidying up and forgot I'd put it there. Alan "Franklin" wrote in message ... My monitor's display seems to twitch slightly every ten minutes or thereabouts. It's just a very small movement but I notice it easily when I am reading the screen. The movement seems to be mostly in the horizontal plane. It never used to do this. As best as one can guess, is this likely to be a fault with the monitor or with the graphics card? The monitor is a 17 inch CRT and the graphics card is an NVidia GeForce2. Both are about 3 years old and have worked faultlessly up to now. My mains power supply seems fine. I recently removed several devices from my PC (three hard drives) so PSU is more lightly loaded than it has been. |

nearly went and bought a new monitor this summer, as the same was
happening to me only on the vertical plain on one side. Looked for a solution on various tech sites. One fellow had said that the routing of my monitor cable was passing to close to power cables/outlets and sure enough I moved it away and the monitor is perfect for the last 4 months.

Sizzling noise at the same time so probably voltages of 50 volt or less. Cracking noise would be higher voltage area. Sometime I'll take the cover off and trace the dry joint/loose wire. ********* electronic hints and repair briefs , schematics/manuals list on http://homepages.tcp.co.uk/~diverse |

If you wait until "someday" chances are you'll be doing much more troubleshooting and component replacement than if you fix the solder joint now. Bad solder joints are the cause of probably 60% of power semiconductor failures. |

It could be an optical illusion. I have heard of such an effect, but
don't recall the specifics. Apparently easily reproducible if you know how. Franklin wrote: My monitor's display seems to twitch slightly every ten minutes or thereabouts.
