Conference Adapter Kit

Description, pictures and information on adapters needed for conferences which wish to use HDMI2USB device.

Passive adapters are just pretty much plain wires, this makes them *really* reliable. They can only really be destroyed with a great effort. Quality rarely matters here, buy the cheapest you can.

Active adapters have powered silicon chips inside them. This often makes them less reliable and more likely to get destroyed as the chips can be damaged by ESD, power fluctuations and similar problems. Have spare active adapters. Quality does matter here as they cheaper chips are less reliable.

DisplayPort is a packet based protocol which means it needs active adapters to convert to HDMI.

There is a difference between DisplayPort to HDMI and DisplayPort++ (or ++DP) to HDMI.

DisplayPort to HDMI has active components internal to it.

DisplayPort++ to HDMI is passive and the controller inside the computer does the conversion, this is less compatible.

Is an active adapter, and works by the phone encoding H.264 video to a processor inside the adapter, which then outputs to HDMI.  This is limited to a maximum resolution of 1600x900, and is subject to visual artifacts.

Lightning to 30-pin dock adapters only work to convert USB and audio signals.  It does not convert the signals needed for video.

This appears to be an active adapter, and runs a variant of DisplayPort over the USB connection (like Mobility DisplayPort / SlimPort). They may also implement the display adapter as a USB device, and present it to the host.

Either option, this is an active device, with varying quality.

Some third-party adapters lack a power connection, which is an issue with the Macbook which only has one USB-C connection which is also used for power.  This will cause the laptop to engage extra power saving features which will reduce performance.

Phones with USB-C may not support this display mode.
