To clarify the issue described in the post and video above (https://www.dell.com/community/Monitors/U2723QE-Smart-HDR-is-useless-b-c-of-the-dimming-implementation/m-p/8175482
It can be reproduced with any U2723QE unit. I assume that Dell's intention to use 4 backlight zone panel was to reduce the cost. However, in complex scenes with enabled HDR the monitor may switch on and off a quater or even half of the panel. This results in an assumption by many customers that the monitor fickers. But in fact, it is a design flaw of using 4-zone dimming panel. See video for more details, in the end there is a real example in a video game.
