Thanks! I don't know about my relative's monitor, but the monitor attached to the T42 has a dedicated "Auto" button. I think I had waded through the separate menu choices without success, but I never tried that "Auto" button. Pressing "Auto", the image futzed around for a few seconds and then apparently aligned properly. It didn't even mess up my brightness setting. Sigh... I'm getting old. I guess I'll add that for a long time, this monitor was dual boot, and I wasn't too interested at regaining the pixels in Ubuntu, only to lose them or their corresponding columns on the other side, under Windows. Nowadays, no longer a concern...
