CHAPTER 3
CONNECTING POWER AND DEVICES
Connecting cables for room computers,
guest laptops and other input sources
You can connect cables to the display so that users can connect and use room computers, guest
laptops or other devices, such as Blu-ray™ disc players.
NOTE
For information about configuring connected computers, see Chapter 5: Configuring connected
computers on page 49.
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.
1
The performance of cables longer than 23' (7 m) is highly dependent on the cable's quality.

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.
See

information.
[N/A]
Use a USB extender if the distance between the
computer and the display is greater than 16' (5 m).
