3.3 DDC Detection
DDC detection is possible in Windows 95. This feature enables
Windows 95 to query the monitor, and if the monitor is DDC
compliant, to return specific detailed information about the
monitor. This information includes the manufacturer, model
number, maximum resolution, maximum refresh rates, and other
monitor-specific details.
If the monitor is not DDC compliant, Windows 95 detects it as an
Unknown Monitor and prompts for a definition of the monitor.
The DDC feature provides full support for DDC-compliant monitors
and the flexibility to customize settings for any non-DDC monitor.
The first time you run Windows 95, the DDC communication occurs,
and the maximum refresh rate for that particular monitor is set.
If that refresh rate is unavailable in the video BIOS, the BIOS
will step down to the next available refresh rate.
