I purchased for my self as kind of Christmas present a Cisco Webex Deskpro. What a great device!. One thing I can not figure out yet. Contrast and brightness. Brightness is automatic, but the contrast I can not control. The WebEx “overlay” contrast is fine, but by USB-C monitor input ( no difference with HDMI ) is not as crisp as it should. Black is not black and white is yellow-is. When you have a “regular monitor” you have all kinds of schema’s and controls to alter the screen output.
