These relationships look correct, the number of used pixels and lines is known, but the refresh rate is not, and neither is the length of the unused line on either side, the number of unused lines at the top and bottom, and the time taken for the retraces. One can guess their approximate values of course, but that's not what I wanted to know. The mode lines in the X server config controll these timings. For example the vertical refresh rate changes by several Hertz when playing with the timings. If you have a working xvidtune, run it and see for yourself. I haven't found any equivalent to xvidtune yet, nvidia-settings doesn't show the numbers (although it would be easy). Interestingly, my font rendering on xorg nv looks like rubbish, whereas the nvidia one is very good, but that's a different topic.
