the webcam doesn't have any settings or configuration that would enable you to rotate it, so if you use the monitor in a portrait orientation, your camera will be rotated 90 degrees. this seems like something really easy to compensate for in software, but it doesn't currently seem possible. zoom can compensate for this, but other video chat apps cannot.
having bought this monitor simply because it had an integrated webcam, to have this particular flaw costs the products 3 stars. it is otherwise a fine monitor, but one of its key selling points makes it essentially unusable for my needs.
