Jerry, Lest anyone get the wrong idea: your monitor is a 25-line monitor -- it just has old-timers disease.
This is a common enough problem with aging monitors. The only variation on this theme that I've seen is the rare case where such a monitor will show this behavior on one video card, but not another. If you plug it into another machine and the view looks the same, then you have a repair scenario. If it looks normal on another card, you may still need it repaired, but the signal is within acceptable limits for this device. Not all video card outputs are created equal, so you may be able to use that to advantage. ~~Garry * [EMAIL PROTECTED] ----- Original Message ----- From: "Jerry J.
