Hi Folks - I have a 75inch q60ra and it's a great TV - however when I watch some TV content it occasionally dims the whole screen momentarily and then brightens up again. It's quite annoying.
ive turner off the Eco stuff and so on but it's still happening - can anyone advise as it's really starting to bother me.
Does this happen on all sources? Navigate to Settings > Support > Self Diagnosis > Picture Test, and then follow the on-screen directions. Does it appear during the test?
Yes, and it only seems to affect 4k HDR content. Its incredibly annoying and doesn't appear to an issue with any of the ECO or Power Saving settings. The only solution that seems to be credible beyond the basics is outlined here : https://www.youtube.com/watch?v=ov9niiau5x4 but I dont want to delve into the service menu on a TV this new or expensive. I find it very very hard to believe that Samsung are not aware of this issue.

They ARE aware of it. It has to do with Local Dimming and the fact that Samsung won't allow you to turn the option OFF unless you know how to get into the TVs service menu. There's a massive thread filled with replies from people with the same problem. It plagues many of their TVs.
I bought an 82" Q60R a few weeks ago. No matter what settings I used the screen dims on dark material. This is particulary annoying when using subtitles as these dim as well. Then I found a solution that seems odd. If I turn on Intelligent Mode with Adaptive Brightness - No more dimming! One would think that if it was on the dimming would occur. Also I am not seeing it respond to dark or bright room changes which is what I want. Hope this helps others.
The only fix I know of is to change the picture mode from Dynamic to either Movie (gives you the most accurate colors but the dimmest picture) or Standard (a compromise between brightness and color accuracy). If Standard isn't bright enough with the backlight maxed, set Contrast Enhancer to High.
