Question
My monitor is 6 months old, and has always worked fine, but now the automatic adjustment bar comes up at different times, and self adjusts itself. This happens in "spells". It will be fine for awhile, and then start to misbehave. I had problems with my DSL connection the other day, but I don't know if this is just a coincidence, or if I have problems. I have done all the self-help things, but still it acts up. Thanks for any ideas you might have. Janet
Answer
1)certain programs will change your screen settings for their own purposes. This should not happen alot though. See if you notice this happening when you are performing certain tasks.
2)make sure your screen settings are not a setting for a wide screen monitor. (right click the desktop, select properties and settings. Move the slider to the desired setting and click apply). If you have a wide screen monitor you may still want to do this.
3)Set the monitor to default factory settings. This can be performed using the menu buttons on the front of the monitor.
4)try to move speakers away from the monitor.
