Screen Lock allows you to control the availability of the InstaShow Host for use. When Enable is selected, use of the InstaShow Host for presentation purposes will be prohibited and a lock screen will be broadcast by the InstaShow Host (as shown below) as the LED flashes red. When Disable is selected, normal use of the InstaShow Host is allowed. EDID (Extended Display Identification Data) is the data provided by digital displays (e.g. projectors, TVs, etc) to indicate their capabilities to its media source. When properly connected InstaShow™ delivers HDMI signals from your video source (i.e. laptop, etc.) to the HDMI display. In order to deliver the optimal audio and video format supported by the InstaShow Host, InstaShow button, and HDMI display, the InstaShow Host reads the EDID data provided by the connected HDMI display and determines the optimal video resolution and audio format based on the video resolution and audio format supported by InstaShow™. Once the InstaShow Host decides the optimal video resolution and audio format, the revised EDID will be sent to the InstaShow Button to replace the old EDID. The video source (i.e. laptop, etc.) then automatically outputs the best or suggested video resolution based on the EDID of the connected HDMI display. In order to check the EDID status, the InstaShow Host reads the EDID whenever a display is plugged in, unplugged, or powered on/off. Whenever the InstaShow Host discovers that the EDID of a connected display has changed (i.e. when there has been a change of display), the InstaShow Button's EDID will be updated when the InstaShow Button or InstaShow Host restarts. 50 Web management

Screen Lock
allows you to control the availability of the InstaShow Host for use. When
Enable
is
selected, use of the InstaShow Host for presentation purposes will be prohibited and a lock screen
will be broadcast by the InstaShow Host (as shown below) as the LED flashes red. When

is
selected, normal use of the InstaShow Host is allowed.
EDID (Extended Display Identification Data) is the data provided by digital displays (e.g. projectors,
TVs, etc) to indicate their capabilities to its media source.
When properly connected InstaShow™ delivers HDMI signals from your video source (i.e. laptop,
etc.) to the HDMI display. In order to deliver the optimal audio and video format supported by the
InstaShow Host, InstaShow button, and HDMI display, the InstaShow Host reads the EDID data
provided by the connected HDMI display and determines the optimal video resolution and audio
format based on the video resolution and audio format supported by InstaShow™. Once the
InstaShow Host decides the optimal video resolution and audio format, the revised EDID will be sent
to the InstaShow Button to replace the old EDID. The video source (i.e. laptop, etc.) then
automatically outputs the best or suggested video resolution based on the EDID of the connected
HDMI display.
In order to check the EDID status, the InstaShow Host reads the EDID whenever a display is plugged
in, unplugged, or powered on/off. Whenever the InstaShow Host discovers that the EDID of a
connected display has changed (i.e. when there has been a change of display), the InstaShow Button’s
EDID will be updated when the InstaShow Button or InstaShow Host restarts.
