Two monitors are connected to a Gainward display adapter, but it is impossible to get the second
monitor working.
This behavior indicates that either, the primary monitor or the secondary monitor, or both monitors together do not
comply with the DDC2a or DDC2b standard. The DDC2a/b standard is a Plug&Play definition that amongst others,
clearly defines power saving properties. Windows-based operating systems can only use one power
management standard. To prevent serious damage to any non-DDC2 compliant monitor the nView feature is
disabled in the display driver. (The DDC2 issue is a mandatory requirement from Microsoft to pass the “Windows
Hardware Quality Labs” (WHQL) certification.
1.
Try switching the primary and secondary monitors to determine if this is a workable solution.
2. Check your user manuals of both monitors. Some newer monitors can be configured to become DDC2
compliant via the monitor’s OSD – Setup (On Screen Display Setup). This software is built into some
monitors.
3. If nothing helps get a DDC2 compliant monitor.
