Samsung TV dimming with Eco Mode off

I recently purchased the Samsung Frame QE43LS03RAUXXU and the picture is constantly altering brightness.

I have turned off all Intelligent Mode Settings and all ECO Solution settings but it brightens and dims the screen every time there is a camera cut.

This happens on HDMI input and Apps so it's not a problem with the input.

According to the TV I am on the most up to date firmware (version 1335) 

I tried to capture a video here:

Solved! Go to Solution.
