auto adjustment in progress - what is this ?

[birdsofparadise]

When I fire up my computer each day I am hassled by a intermittent flashing "AUTO ADJUSTMENT IN PROGRESS" It flashes so frequently that it is impossible to focus on anything. After some time it will slow down or stop especially if I am not doing anything... then as soon as I move or click on something - it comes back. This is incredibly annoying - what causes this and how can this problem be remedied ?

does it do the same thing in safe mode as well? does it do it on other monitors or just the one? have you tried resetting your monitor to factory defaults (generally a certain combination of button presses)

When you have an analog (VGA) connection to the monitor, there is no set top/bottom or left/right. The video card continuously sends a signal to the monitor. A special change in the signal determines when the top starts, when the left side starts, etc. If you ever messed with an old analog TV and saw what appeared to be a horizontal or vertical bar just off the edge of the picture, that's what it was - a sync signal so the TV could determine where the top, bottom, and sides of the picture were.

Adjusting the image so the picture shows up in the middle of your screen is called synchronization. You had to do this manually on older TVs. Newer TVs and monitors could do it automatically (electrically measure where the bars are and synchronize the signal). That's what the "auto adjustment in progress" means - the monitor is trying to sync its display with the signal.

The fact that your monitor keeps loosing sync could be an indication of a variety of problems. The easiest possibility to fix is a bad video cable, so give that a shot first. Or if your computer has digital output and the monitor has digital input (DVI, Displayport, or HDMI), try using that instead of VGA. Digital signals don't need sync, so this problem goes away. If only one has digital and the other is analog, you could try a converter, like an HDMI to VGA adapter.

Next easiest is that the sync rate of your resolution and refresh rate is just barely within the monitor's capabilities. So try changing the resolution or, if it's an LCD and you'd prefer to keep it at a specific resolution, change the refresh rate from something other than 60 Hz or 59 Hz or whatever you're currently using. Updating your video drivers might help with this as well.

Doing a factory reset on the monitor is worth a shot, but the auto adjust usually scans through the entire sync range so I'm doubtful it'll help. The other possibilities are a lot more expensive to fix. Your video card isn't putting out a clean signal or its sync timing is unreliable (using a digital to VGA adapter could fix this), or your monitor's VGA input is flaky (in which case digital input would bypass this).
