I have two of them and in the meantime I wasn't sure whether I had bought the same models, as I bought them a month apart. In the end, however, it fits, but due to minimal deviations in the factory settings and the need for calibration, as well as the fact that the two mounts do not seem to be aligned quite the same in terms of height (approx. 3 mm), I assume that the monitors differ slightly, depending on the time of manufacture or the serial number (although I am not familiar with the manufacture). Ultimately, however, they are identical.

Does not exist. It was just a name change as far as I know.
