CHAPTER 3
CONNECTING POWER AND DEVICES
Using recommended cables
SMART recommends the following varieties of cable:
Cable type
Maximum length
HDMI
23' (7 m)
VGA
23' (7 m)
Stereo 3.5 mm
20' (6 m)
USB
16' (5 m)
Using cables that exceed these maximum lengths may produce unexpected results, such as
degraded picture quality or degraded USB connectivity.
Connecting to the side connector panel
The side connector panel includes two HDMI video connectors: HDMI 1 and HDMI 2. Both
connectors can accommodate an HDMI cable for video and audio, and both support HDMI 2.0.
NOTES
The USB Type-B connector for touch control is located on the bottom connector panel. See

Connecting to the bottom connector panel on the next page.
You can connect a wireless USB keyboard and mouse to the two USB Type-A connectors.

The performance of cables longer than 23' (7 m) is highly dependent on the cable's quality.

Recommendation
1
Use only certified HDMI cables that have been
tested to support the performance standard you
require.
Use VGA cables with all pins in their connectors fully
populated and wired.
[N/A]
Use a USB extender if the distance between the
computer and the display is greater than 16' (5 m).
For more information, see USB extenders on page 9.
