Using recommended cables
SMART recommends the following varieties of cable:
Cable type Maximum length Recommendation
HDMI 23' (7 m)
1
Use only certified HDMI cables that have been
tested to support the performance standard you
require.
VGA 23' (7 m) Use VGA cables with all pins in their connectors fully
populated and wired.
Stereo 3.5 mm 20' (6 m) [N/A]
USB 2.0 16' (5 m) 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.
USB2.0 cables support Hi-Speed (480Mbps),
whether connected to a USB 2.0 or USB 3.0
receptacle. For SuperSpeed (5Gbps), connect a
USB 3.0 cable to a USB 3.0 receptacle.
USB 3.0 9' (3 m) SMART supports only installations that use directly
connected video and USB cables, AC-powered
extenders, or USB extenders purchased from
SMART.
You might be able to use higher-grade cables that
are longer than specified. If you have problems with
such a cable or an extender of any type, test the
connection with a shorter cable before contacting
SMART Support.
Using cables that exceed these maximum lengths may produce unexpected results, degraded
picture quality or degraded USB connectivity.
Connecting USB drives, peripherals, and other devices
You can use USB drives, peripherals, and other devices with a computer connected to the display

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