It is important to say that our graphics controllers support DDC/CI besides some other technologies and these are automatically activated by installing the graphics driver.
You can check more information about this at the following link:
We recommend you installing the latest graphics driver from our side. You can download it at the following link:
At your first link - http://www.intel.com/support/graphics/sb/CS-020934.htm?wapkw=020934 - it is stated that the page applies to 2nd Generation Intel® Core™ Processors with Intel® HD Graphics 3000/2000. Intel(R) HD Graphics 4600 is not listed.
Also, I had an error in my first message. I have already downloaded and installed the latest driver version 184.108.40.20665 available at your second link. It did not help.
Do you have any other suggestions?
The Intel® HD Graphics 4600 indeed supports DDC/CI; this is a feature that started to become available since the Intel® 82845G Graphics controller which is an extremely old graphics controller.
Please note the website is not up to date, reason why the Intel® HD Graphics 4600 does not show up; however, the processor features are not downgraded with new releases, instead, they are improved.
DDCI/CI support is already included on the driver; if any issues are presented with the software having the latest graphics driver, our best recommendation is contacting a Field Application Engineer for coding assistance as this would basically mean the software needs to be configured.
The latest graphics driver can be found at: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22842&lang=eng&OSVersion=Windows%207%20(64-bit)*&DownloadType=%0A%09%09%09%09%09%09%09Drivers%0A%09%09%09%09%09%09
