Problem with HDMI stutter playback

Hello, I’ve recently purchased the latest version of Infuse 7 for my Ipad Mini 5, I have a lightning to HDMI adapter (original from Apple) that works with any streaming program.

When I connect my Ipad with an Hdmi cable to a device (tv, projector, etc., even with different HDMI cables) and I start a movie, the playback start to stutter immediately, but when i watch a movie on the Ipad mini screen it plays without a problem.

Can you help me?

Thanks in advance

Is this affecting all videos, or just a few?

Do you see a difference between 4K and 1080p?

Does adjusting the settings in iOS Settings > Display & Brightness > (Your TV) have any effect?
