- This is no big deal. Monitors that sync at 120 Hz have been around
- for quite some time. One of the primary uses of such monitors is to support
- stereo viewing, which usually works by doubling the vertical sync rate and
- sending alternating frames to each eye separately. For such an application
- 100 Hz would probably result in too much flicker (50Hz frame rate). For normal
- viewing these high sync rates would be pretty meaningless since no graphics
- card in existence supports them, AFAIK. Also, some people may be confusing a
- 100 Mhz *bandwidth* (as opposed to 100 Hz sync rate), which definitely does
- have advantages in terms of a sharper picture (all else being equal).
