Delayed image on second monitor, MacBook Pro 13 inch i5
The problem is because analogue (VGA) connection is used and the "auto" positioning does not detect the image bounds correctly. Check your monitor controls (menu) and move the image left/right and up/down (usually labeled HPOS/VPOS). Here are my recommendations:


Use the native resolution (1440 x 900) and 60 Hz refresh rate.
If still not centered, use the monitor's controls to position the image.
If this does not work - try lowering the resolution or changing the refresh rate and again centering the image.
