Beware: there are no built-in speakers in the HS model.

Just received my S2721HS model and was not getting the expected sound either through HDMI or DisplayPort. Checking closer on the Dell site, no wonder: It's either the adjustable stand for the HS, or speakers for the H model, not both. Amazon’s title description was wrong and only the higher models in this series (DS or QS) have speakers along with the adjustable stand. Separately, I'm giving four stars because I find the sharpness of text not satisfactory. In fairness, the pixel size of native 1920 x 1080 is probably not fine enough for 27in screens if one is looking for the finest text.
Update: If you want a "perfect" looking 1920x1080 27in, buy a 3840x2160 (4K) monitor instead, such as the Dell 2721QS, and scale it down to 1920x1080. Because the 3840x2160 resolution involves whole number multiples of pixels relative to the 1920x1080, the scaling down to 1920x1080 gets you identical clarity as with the native resolution, only much crisper due to the higher pixel density of the panel. That's what I did and got the 2721QS as replacement. Stunningly clear and crisp down-scaled to 1920x1080 on a 2014 Mac mini. You just want to make sure in your computer's specs that its graphics can handle a 4K monitor.
