I ordered this adapter to wall mount my Samsung PX2370 monitor with a VESA swivel mount. The adapter fits perfectly on the bracket and all the holes match up perfectly. There are four holes on the bottom of this adapter bracket. You can use any of these four holes to attach the adapter to your monitor. I don't know if that was intentional, but it was nice to be able to choose how far from the adapter I want the back of the monitor. The only downside to this adapter is that it requires the use of a screw that secures the monitor. Hand on a flat table top. I tried reusing this screw but it was too short and about 1/4" too short from the threads on the monitor arm. I got lucky, I went to my screw jar and was able to find the screw. It worked. I don't know wondered if the adapter usually comes with a longer screw but after checking the packing bag/stuff a few times I couldn't find it so that's why I'm giving 4 stars If a longer, this adapter was included in the kit, this adapter would easily be rated five stars. As a side note, there are some reviews here that mention that the single-screw mounting system is a weakness of this adapter. The Samsung PX2370 has only one desktop base mounting screw, which has worked very well for me over the last few years worked. I see no reason why a single mounting screw with an adapter would be any less secure when using the correct length screw.
