I found this fixed my issue. The resolution was 4k'is and refresh rate was 30hz. I suspect this is due to limited resources based on my particular hardware setup. In any case switching from 30hz to 60hz also reduced the resolution to half of what it was. This was a win-win in my case as I didn't need/want 4k. I do have a pretty old machine and I am pumping this all through USB3 so probably a resource issue and then the slow refresh confused my considerably, compared to PC, newer HDMI --> TV <-- . Forgot to add, I am using a TV. I also tried configuring my TV HDMI input to allow for slower synch but that did not resolve the issue when using 30hz. Good luck! Edit: This was with Windows 10.
