Successfully got my Roku to mirror my PC screen although the display isn't quite sized right, I can live with that. What I do have an issue with and cannot seem to fix is the constant pulsing of the image.
It is like a sudden blurring of the image at the pace of a resting heartbeat. I got a video of it. I have been through all of my video options to no avail and I really have no idea how to remedy this issue.
If this doesn't work I will post the video to my YouTube account and share that here instead.
