So after giving up entirely on the SEDK1102, I opted for the SEDK0701. Thankfully, with this dock I was able to push video to three monitors, however, the resolution on the third display is terrible. I'm currently running Samsung Odyssey G5s (2 24" and 1 32") in the following configuration:
System specs are as follows:
I've updated drivers for the Intel UHD 620 card and that didn't seem to help. I've also set the BIOS to run high resolution over USB-C. That seemed to only help for the second display which was maxing out at 800x1200 in portrait, but is now able to render 1080x1920. After all I've tried, I can only get 720x576 out of the third display. Would love to get a fix for this so I can actually use all three monitors.
