Using recommended cables
SMART recommends the following varieties of cable:

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 a 3.5 mm stereo jack (15 mm long barrel) only 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
page14.

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