I've recently ordered a second monitor for my pc but my desk isn't big enough for both monitors because the stands that come prepacked with them make them stand a good 6 ins away from the wall. I was looking into a dual monitor stand (either fixed to the wall or the desk) but I'm worried because the main one I was is a BenQ 24" LED monitor, the other (same brand) is 21.5". I'm not sure if a dual monitor stand would take both because of the difference in size and (most likely) weight. I would like to know because it's either the dual monitor stand or a bigger desk.
Any advice would be much appreciated.
