I was contacted by Dell, which said the same as mentioned in the documentation, so I guess I'll never know the real reason.
I have this OSS21 SFF stand, with a 27" monitor. I am interested in purchasing a 32" monitor to replace it, but the OSS21 documentation says it's for monitors up to 27", and I wonder why. I would like to understand the constraint(s) so that I can decide for myself what I do with it. Does anyone know why it has this documented limitation? Weight?      [URL]  
SFF OSS21 stand : OK with monitor larger than 27" ?
