I'll add this to the list of things I learned today. Apologies for the |
33 |
inconvenience. |

I am now using a VESA-compatible modeline for 1280x1024@75 (not sure |
55 |
about the last one). I just pasted it from ddcxinfo-knoppix, knowing |
56 |
the monitor would work with these settings. |
57 |
|
58 |
One more question, though. If I switch back to my older, smaller |
59 |
monitor and forget to change the modeline, will it get fried? I seem |
60 |
to see this warning quite often. |
61 |
|
62 |
Thanks for the help, |
