So, in treading a thin line, to hopefully keep the forum police happy, I will post my experience's with Samsung's AMP that I've had with numerous models I've owned from Samsung. With Samsung AMP it could be be said that they seem to go down a different path from most manufactures, such as Sony who, according to what I've read, seem to implement it better, however I have no personal experiences of that brand. But it can be a matter of individual personal preference to what they are set too and I have read of extremes that I could never live with. Generally though there tends to be two settings in the majority depending upon what the source is. Also note that some Samsung sets had a AMP bug where it was actually on when all the settings were set to off, but I don't think any of their current TV's suffer from this.
With most content I have found setting AMP to off works fine, however I have experienced the halo effect around moving objects and slight stutter when viewing through the built in apps, such as Netflix. There the preference can be set to custom and all settings to zero but it isn't a setting required required by all Samsung models, with every apps and our personal preferences.
Hence why the AMP settings can require some experimenting with do find your ideal personal preference and what source.
To complicate things some users are experiencing sound and picture stutter with certain SkyQ boxes, although I have not experienced this myself..
