- Although sometimes you can have more than one "apparent" resolution with
- one horizontal frequency to a monitor, usually this is not the case. As
- stated from the chart above, moving from 640x480 to higher frequency for
- example, the horizontal frequency has to be increased as well. Otherwise
- you don't have a picture! On the other hand, if you are driving the
- monitor at 60kHz (approx.) with 1152x900 resolution, for example, you
- can down the size of the resolution to "virtual" 640x480 without
- decreasing the frequency, but not possible to increase the resolution to
- 1280x1024 without increasing the frequency to 68kHz. (My data might not
- be accurate, but you get the idea).
-
- Therefore, as a general rule, multiple resolution almost always associates
- with multiscanning because of changing driving horizontal frequency.

- I don't mean to flame. Mr. Seymour knows very well in most of the matter,
- and he explained well on the Trinitron technology without mistakes. But
- I'd like to clear up several ones he made in other postings. It is not
- personal.
