Many of the cheap KVM models do, indeed, mess up the EDID data coming |
| 7 |
from the monitor. I suspect that this is from old design specs that |
| 8 |
have too much pull-up/pull-down on the EDID lead since the boxen haven |
| 9 |
been re-engineered for newer, higher resolution and higher speed monitors. |

I have had problems specifically with the BELKIN KVMs. |

It may also be that the video drivers for Linux are just enough |
| 14 |
different (necessarily) from the MSFT drivers to not reliably sense the |
| 15 |
EDID return signals. |

I did as others suggested and tried several until I found one that |
| 18 |
worked. Sometimes a slightly different model/serial/part no KVM from |
| 19 |
the same manufacturer would/wouldn't work. |
