In each classroom or meeting space, there are 15-foot-long HDMI cables including multi-device connectivity dongles.
Convenient video dongles
Although Zoom can be used as a backup screen-share option, experience has shown us that in-person classes still sometimes hinged on the presence or absence of the right video adapter. Now you will find a slew of adapters tied to every HDMI cable. These cover modern and legacy cable types and, best of all, won't suddenly disappear between classes.
Which adapter should I use?
Whatever fits!
First try the cable with no adapters at all. If you can't find a slot on your computer that matches, try out the dongles until you find a winner (in most cases, it'll be the green adapter seen above and below).
