    Could be an encoding issue. The data rate may spike when there is significant change in the content.

    Could be the HDMI connection. Are you using any HDMI extender? Can you try with a short HDMI cable?

    We see flickering/stutter when frame rates do not match between the display, presentation, and video encoding.  We notice it most when text or video is moving horizontally.  If we do everything at the same frame rate (60p) we do not see the issue.

    As mentioned above, it might be an encoding problem. Always remember to use PROGRESSIVE scan when rendering Your video and not INTERLACE (like in the old days, with CRT monitors). Progressive is 23.976 frames / second.

    You can also look at this link, where there are very good information about the issue

    Good luck with the encoding
