Knoppix is doing its best autodetecting the PC's hardware and in many cases it gets it right. In this case I think it is setting the video resolution & refresh rates beyond the capabilities of the monitor.

Knoppix boots with a splash screen. At that splash screen you can enter codes which will force Knoppix to do certan things. Theses codes are known as Cheat Codes (http://www.knoppix.net/wiki/Cheat_Codes). You should try the ones that involve the video, such as:
knoppix vga=normal
knoppix vga=normal screen=800x600 xvrefresh=60

Where do i use the cheat codes?

Knoppix boots with a splash screen.Do you see a splash screen at all? It should look something like:
