EDID data source
« on: December 09, 2013, 10:43:09 am »

 I do not know if this will be of interest to the winbatch community.  While investigating screen resolution, I came across the command utility DUMPEDID.  I was able to use this utility within a winbatch script to create a text file that contained information regarding resolutions supported by my monitor.  It also contained data regarding the monitor itself.  Since one of the pieces of data was a registry key, I believe this information is being retrieved from the registry.  This text file contains 2 sets of information.  I believe this is because my video card has 2 display adapters.

Sample text follows...

DumpEDID v1.01

I think that a winbatch script could be created that reads this file to display this data and maybe process the resolution data to display allowable resolutions for this monitor(this text file does not contain color depth).


 The following is a 2 line example of executing this command line utility to create the above text file.

  coms = Environment("COMSPEC")
   RunWait(coms, "/c c:\dummy1\dispedid\dumpedid.exe >monitor.txt")
