A modeline is a one-liner way of representing a display driver mode. I |
| 16 |
always preferred the block form; it's far more readable. It's been |
| 17 |
almost a decade since I've written one, though. Haven't really needed |
| 18 |
to since XFree86 4 came out. |

I don't remember all of the bits of information in it, but here are |
| 21 |
some of the highlights: |
| 22 |
* Vertical refresh rate (in kHz): how rapidly the CRT's electron beam |
| 23 |
crosses the screen horizontally. |
| 24 |
* Horizontal refresh rate (in Hz): how rapidly the CRT's electron beam |
| 25 |
crosses the screen vertically. |
| 26 |
* Some horizontal and vertical overdraw values I don't remember the |
| 27 |
specifics of, but it amounts to realizing that the electron beam is |
| 28 |
active past the bezel of your monitor. |

"xvidtune", by the way, was an awesome way to do live testing and |
| 31 |
configuration of these values, and it would emit a modeline for you |
| 32 |
when you asked it. |
