Unusual 30 ich monitor problem
My 30 inch aluminum monitor very often shows a noticeable "gray
smudge" in the left center area (extends from the left edge to about the center of the screen and in the middle relative to vertical position; perhaps 2.5 inches in height). If I set the screen intensity to HIGH it will disappear after about 10 minutes. Usually the screen remains normal after this initial burn-in for the next several hours.
Very infrequently the screen behavior is normal following the initial boot process. Infrequently, the gray area returns if computer is little used while operating.
This phenomena is independent of the type of Apple computer driving it. O S is 10.5.6. Most often used with a MBP 2.5 GHz core 2 duo.
Think one of the back-light tubes is bad, but why does it always return to full brilliance?
Thanks for your suggestions.
