This case fits perfectly on my new 22 "16:10 LCD monitor (1680x1050) and fulfills the purpose to protect the screen surface from dust. Unfortunately, it is open at the back, which on the one hand has the advantage that they each monitor, as well fits with (as in my case) behind an integrated power supply, on the other hand, of course, has the disadvantage that precisely the power supply and the rearward parts incl. vents are of course not immune to dust.
Therefore only 4 stars. Otherwise all is well, there is no material error or the like.
