The HDMI5 features receiver equalization that can be used to com-
pensate for the losses that occur in var ying length, and var ying
qualit y, cables.
A1 A2
The HDMI5 allows for 15 levels of equalization. Using high qualit y
DVI or DVI to HDMI conversion cables, the HDMI5 can compensate
for cables of up to 65 feet (20 meters), on all its inputs and still
reliably receive a stable, spar k le free image at 100p. Longer cable
lengths can be achieved at lower resolutions.

When a cable's tuning is too shor t, the display will begin to spar-
k le, eventually going blank . For best results, star t long, and use an
equalization a step or t wo above any noticeable ar tifac ts on the
screen.
Note: O utput c able lengths depend on the display's receiver's
c apabilities, and the qualit y of c abling used. The HDMI5
uses source termination to compensate for all lengths of
output c ables, and to help in c ases where the receiver
may not have followed the specific ations properly.
Note: Each input c an be tuned individually andall settings are
saved in non-volatile memor y and are not affec ted by a
power failure.
