First, meetings are expensive, and getting a meeting started on time is critical to keeping your meeting costs low. If you have an office space with meeting rooms and collaboration spaces, choosing the right system becomes more important. Buying, managing, and often losing these adapters can be a hassle – and waste time in obtaining and configuring the right adapter to make a presentation. Other laptop manufacturers such as Dell, HP, and Lenovo also have produced models with all four of these wired interfaces. For example, and older Macbook might have a VGA port or a full-size HDMI port, while a newer MacBook might have a mini Display port or USB-C Thunderbolt video output. The challenge today with wired connections is that many models of laptops have different video outputs that require different types of adapters. There are many kinds of VGA to HDMI adapters available, as some only carry video signals while others separate the audio and video signals so they can be sent over legacy analog systems.

If a classroom or meeting room still uses VGA cables, an HDMI to VGA adapter will be needed. While older laptops have legacy VGA ports, newer models come with digital ports that share HDCP information with the display to enable copy-protected content to run. Cables are the most secure and often the fastest way to connect a laptop to a projector.
