I get this problem too. Also my display is noticeably more crisp at the bottom of the screen.
Date: Sun 15-Feb-1990 15:06:27 From: Unknown Subject: MegaPixel Peculiarities My MegaPixel display is exhibiting classic 'bowing' tendancies. Additionally a slight 'dog-ear' trait is evident on the top corners (right is most evident). I trust that this is not typical of other machines or is it? I admit to being extremely sensitive to monitor idiosyncrasies, but this is quite annoying. Aside from the question as to is this typical; is it a monitor adjustment (added pincushioning), or a video controller [non-]adjustment? Thanks - kevin --------------------------------- Kevin D.

Since they don't have a DE-GAUSS button (I assume) you may need to take a big magnet and run it around the outside edge of the monitor. Of course if your monitor explodes, warrenty expires, or I'm just plain wrong I will flatly deny saying this ;-) std.disclaimer: I don't have a NeXT, but I play one on TV tima@polari uw-beaver!sumax!polari!tima >From: flur@duke.gatech.edu (Peter W.

A couple of years ago I got a Sun 3/60 in my office at school. At first boot there was a striking purple blush across one corner of the hitachi monitor. We had the Sun service reps out several times with hairy degaussers, swapped several boards, monitors, &c before our sales rep got the idea to lug the monitor around the office. Amazingly the orientation in the room had a dramatic effect! The cheery ending is that after several weeks the problem went away on its own. Somewhat like the story of how a swiss watchmaker fixes a slow clock ....

I admit to being extremely > sensitive to monitor This is typical of other machines. We have several NeXTs here at Miami, and we found out what caused it. The monitor is actually visibly sensitive to the earth's magnetic field! I can't remember which orientation gave the best picture, but I believe that is was the user would be facing west if using the NeXT (right side pointing north, left side pointing south). Try orienting it in different directions. You should find it will clear up the problems, however slight they are. > idiosyncrasies, but this is quite annoying.

Another peculiarity (this is strictly rumour, but it sounds plausible) is the cable's 3 meter length may not be changed, or the picture will become distorted due to some filtering aspect of the monitor.
