Thank you for contacting the Intel community.
Please bear in mind that Intel has not validated any splitters or adapters to work with the Intel graphics, also at this point your best contact support is with your computer manufacturer as they are more familiar with your system and how all the components interact with each other. Also your computer manufacturer can provide you with a list of supported components and configuration for your system (BIOS update, software update etc).
This driver has been tested with straight connection (no splitters) and it works without issues.
If you try the graphics driver from your computer manufacturer do you get the same problem?
Check with your computer manufacturer to find out what is the proper graphics driver for your system, they may have altered the feature, incorporated customizations or made other changes to your driver to have it work based on your system configuration.
