Just wondering if anyone here might be up to speed about Sony Trinitron monitors. I've just purchased a Sony G410 (brand new) Trinitron FD 19" monitor. It works ok, is sharp, colors look good, etc.I've noticed however that the screen image changes size slightly as the monitor warms up, and it doesn't completely stabilize into it's final position until 20-30 minutes after power up. I've tried Googling this issue to death, but to no avail. The only answers I've found so far is that this is possibly related to cheap assembly components and shouldn't happen with higher-quality monitors. Several user reviews of this particular Sony monitor suggest that this screen fluctuation during warm-up is a univeral characteristic with the G410.What do you guys think? Is it a Sony thing or do other brands experience a slight screen shift during warm up? Should I be concerned and think about returning it?Thanks a lot.

Other CRT monitors have the same problem. All monitors that I know to behave like this have a diamondtron tube, which is a similar technique to Trinitron, so it might be a characteristic of this type of technology.Allard.
