Prior to the update in mid-January, pressing Ctrl-Alt-Shift-H caused the pop-up Floating Meeting Controls to permanently disappear. This happens for the people in the physical room every time a person enters the waiting room and every time someone is admitted to the meeting. Worse, the people in the physical room now have the floating meeting controls appearing over the shared video on the projector screen, and when you press Ctrl-Shift-Alt-H to get rid of it, a box appears saying to press Esc to get the floating meeting controls back. You can get rid of the grey boxes by unclicking Optimize For Video, but every time a someone arrives in the waiting room everyone's shared video freezes for several seconds, and then when you admit them to the meeting their video screen freezes again for several seconds. The new update in mid January causes grey boxes to appear during screen sharing for all zoom participants. We run meetings with people in a physical meeting room who can see the Zoom participants via a projector to a screen at the front of the room. It is annoying to me that Zoom made such a significant change in an update in mid January without any warning. This workaround allows clicking the Optimize For Video button which improves the quality of video being shared, especially on low-end user devices such as cell phones.


When someone enters the waiting room, or when they are admitted to the zoom meeting, they will appear in the participants list on the main monitor but nothing will appear or cause grey boxes on the shared screen. Drag it to the main screen so the shared screen on the extended monitor has no other windows over it or behind it.

When you share this screen, click and hold the Floating Meeting Controls menu which will appear over the shared screen. Open the window to be shared, move it to the extended screen and minimize it. Pop out the Participants window, the Chat window and any other windows needed for administration such as breakout rooms, and move them to the primary screen. Move the Zoom window to the extended screen. Do not use the Dual Monitor feature in Zoom. Configure it in Windows as Extended Screen. There is a workaround using a second monitor.
