22 |
something like that. I don't usually set it, but I think that's mostly |
23 |
because the only time I have to specify settings myself is when the |
24 |
EDID or whatever isn't working properly. Monitors' support for this |
25 |
mode-gathering stuff seems to vary inversely with it's age. Many of |
26 |
the older ones I have refuse to help X configure them at all. |

++. It's so true. |

I am not familiar with ddcxinfo-knoppix, but it probably lists modelines |
35 |
from up to 3 different sources. The graphics card can supply a list of |
36 |
available resolutions -- that's where 1920x1440@75 came from I bet. |
37 |
The monitor's refresh rates can also be used to extrapolate possible |
38 |
modelines -- I don't know how to do this, but aside from this program, |
39 |
there are websites that can do so for you. Finally, the VESA standard |
40 |
defines what would likely be called generic settings that are supported |
41 |
by any VESA-compliant monitor and graphics card (just about all of them |
42 |
you can still physically connect to new computers, nowadays). These |
43 |
standard values are a good place to start, as your monitor should work |
44 |
for them, and you should be able to find one (1280x1024@70, maybe) |
45 |
that your monitor supports and that looks nice and doesn't flicker too |
46 |
much, and performs well on your hardware. the Modes line is meant to |
47 |
be a list of modeline names, so you may or may not need the @70 part |
48 |
depending on where the modeline came from. the X logs should list many |
49 |
modelines which X came up with after probing the hardware, and you |
50 |
probably want to use a name from the desired one of these. |
51 |
|
52 |
Have you tried looking up online and entering the refresh rates |
53 |
manually? I highly recommend doing so. |
54 |

Best of luck, |
56 |
dan. |
