When testing this monitor, I noticed that the 10-bit color depth is correctly interpreted only for refresh rates below 100 Hz. It looks like that the panel is actually 8-bit native, and uses FRC to simulate 10. The FRC is however not implemented for higher refresh rates, at least in my firmware (V003). The most confusing part about this is that the monitor offers the 10-bit support for all refresh rates available (at least on DisplayPort), but it does not correctly interpret them, and throws away any additional depth in these modes, using only 8-bit of information (hence the “It performs like an 8-bit panel” comment mentioned in the review).
I’ve done this test by downloading testing gradient images and switched the refresh rate back and forth. You can even see the FRC specific “flicker” if you set the brightness high enough in a dark room.
I think that it would be best to include this information in the gradient section of the review.
TLDR; if you want 10-bit depth, you need to set your monitor to 99 Hz or less.
