Using recommended cables
SMART recommends the following varieties of cable:
Cable type Maximum length Recommendation
Display Port 23' (7 m)
2
Use only certified Display Port 1.4 cables that have been
tested to support the performance standard you
require.
HDMI 23' (7 m) Use only certified premium high-speed 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) Use only shielded 3.5 mm cables
Important
Use only a 3.5 mm stereo jack (15 mm long barrel) to
connect to the display.
USB 2.0 16' (5 m) Use a Hi-Speed USB 2.0 USB extender if the distance
between the computer and the display is greater than
16' (5 m). For more information, see
USB extenders
on
page15.
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
exceed the recommended length. 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.
2
The performance of cables longer than 23' (7 m) is highly dependent on the cable’s quality.
