  jirsoft said  I have no experience with this part, but I'm doing some retro computing with C64, C128, Apple IIC... and I'm usually trying to solve to opposite way (S-video/Composite -> VGA/HDMI) and my 2 cents are:
1. with buffered convertor you can (and probably will) have some sync problems with fast animation coming from CMM2 - it will be synced on VGA side and not on the 15kHz side
2. colors will be washed out (you in Germany will have this better with PAL than NTSC, but anyway)
3. this destroying of "VGA quality" will cost you the same money, that you can put into small LCD monitor with VGA input (some 17" or 19")
4. higher resolutions will probably not work


All good points. I bought the Extron for use with my A4000 on a Sony PVM monitor. It cleaned up the signal quite nicely, and made for a pretty easy connection.

Prior to the Extron I was getting a crappy picture, if any at all. Pretty ugly...

A "down scalar", if those exist, might be necessary for this application.

And +1 on your recommendation for going with a more modern monitor. That's the sane approach. I have one that can handle 15khz as well as the "normal" frequencies, so I get the best of both worlds.

You can usually find a compiled list of monitors that support 15Khz at sites such as Lemon64 or Amibay.
