I sure appreciate this information, and I wonder how widely this is known. RU> I cannot find anywhere in the thread a mention of which video card RU> you're using. What is its maximum clock rate? I think I mentioned it sometime near the very beginning of this, but in any case it is an nVida based card, a GeForce4 MX440.

Okay <screaming newbie alert> I had no success with "startx --probeonly". I tried it just about as many ways as I could think of to try it. Maybe it *was* doing what it was supposed to do, and I just did not realize it. In any case, I get X opening, to a desktop I've not seen before. (I tried this both as lance and as root.) Do I need to pipe the output to a file? If so, can you specify the command? RU> If you were you, I'd try all three. If one works then we don't RU> need to bother going any further.

As for trying them, I'm not sure exactly how to do it. There seems to only be 3 modelines at all in XF86Config-4. These modelines do not seem related to the frequency I'm running at, but seem to be for a Sony laptop and some TV settings. Well, I'll give it a go and see what happens. One thing you might clarify for me: It is my suspicion that only rather prolonged running of the monitor (more than 2 or 3 minutes at least) at specifications it's not designed for would damage it. Is that right? If so, I can feel a bit freer to experiment, because I do know how to set the file back. But if I'm risking permanent damage by simply trying a modeline that is wrong, I'd rather not fool around. Thanks for your help, Lance
