The 221S6QYKMB/00 has a built-in camera, which is unusual. Most of the other medium monitors that have been around for more than a year do not have a built-in camera.
Alternative PC screens with a built-in camera currently available which you might want to consider include the NEC E171M (£161.04), or the DELL UZ2315H (£149) which both of have better reviews.
There are a number of alternative PC displays which also have a built-in camera that you might want to look at including the HP EliteDisplay E240c (£165).
