According to the manual (http://www.eizoglobal.com/support...) on page 46 (German), the monitor is compatible with VESA 100x100mm mounts.

I cannot give a guarantee because I do not own the monitor. But the W1A mount is in any case a good product, and as has already been written, it comes with both M4 and M5 mounting screws in different lengths, usable with or without spacers.
That's definitely possible - the VESA standard is there for a reason, namely so that the stuff fits together ;)

Since the VESA is not stated in the product description of your monitor, you will have to measure it yourself. The hole spacing is 100/100 and 75/75. M4 and M5 screws are also included.
