Wow. This review is so way off. I've owned this monitor for several months and it has problems that Samsung has or is still working on to correct.
1) Putting the monitor into "movie mode", actually called "entertain" mode disables its "game mode" which in turn disables HDR, "adaptive sync", and lowers the max FPS to a maximum of 120.
2) This monitor also has some compatibility issues with GPU's ports. Both HDMI and DP. The problem is when you power down your PC and the monitor goes into standby mode, it has to be powered up manually with its remote each time you power up your PC.
This monitor shines on being a standalone entertainment streaming device. But it has some issues trying to act like a simple PC monitor. I'd get the Alienware versions.
Maybe the reviewer has an updated firmware version I don't...yet. But I check daily.
By the way, when it is configured correctly this OLED monitor is amazing in gaming. And for the record, none of the above holds a candle to its color depth and image quality in gaming. You'll see HDR as it is meant to be. You can verify that by searching for and reading other reviews on this monitor. This panel, Alienware, Samsung, MSI is in a league of its own.
