- I thought this wouldn't be possible because:
- 1) The speed (ferquency) of moving the electron-beam of a computermonitor
- is (much) higher then the speed of video (or television).
- 2) There are far many dots on a computermonitor then there are on video.
- 3) There are more lines vertically too.
