What is the specific version of the EMGD driver used on the E6xx on Win7?
Have you tried installing the XP driver on Win7 (yes it should work in XPDM mode but you do not get Aero support).
Have you tried adding the option to the Win7 INF file? It may not be supported but it will not hurt anything if it is not.
Hope this helps.
>> Version of EGMD ?
Version 1.8 for both WinXP or Windows 7
>> Have you tried installing the XP driver on Win7
Yes i tried, and the problem is not present.
But the client want to use Windows 7 version
>> Have you tried adding the option to the Win7 INF file?
Yes, but it did not work !
I did a text search in the driver files but did not find the "DisplayDetect" string.
other value like "DisplayConfig" can be found.
WinXp drivers contains both keys in the driver files.
Well sometimes we do not always get to do what we want. The DisplayDetect feature does not exist in the Win7 specific version of the driver and is not planned to be added.
So you can either use the Win7 version and put up with this particular operational characteristic, or use the XP version of the driver on Win7 and NOT have that issue.
Hope this helps.
It is all a mater of targeted use case for the source base for each solution. The XPDM EMGD code was purpose built for embedded that needed capabilities like leaving an output port alive even when there is no monitor. There is a LOT of configurability designed into the driver. The Win7 specific EMGD uses a different code base where the use case values the driver doing what it thinks is right rather than what the user may want to do so we gain ease of configuration at the loss of configurability. Personally I prefer the driver do what I want which is why I use the EMGD "for XP" on Win7 rather than the Win7 specific driver.
