4K 30Hz vs 4K 60Hz
As our TVs get bigger and bigger, so does the perceived difference
between refresh rates. This splitter supports 4K 60Hz while some of our
other splitters outside of the SplitDeck series support 4K 30Hz, but why
should you care?
As you know, video is simply a bunch of images played rapidly to give
the illusion of movement. More images viewed per second equates to
more-realistic video. Refresh Rates (measured in Hz) are what is used to
describe the number of unique images played per second. 30 Hz means
that you're seeing 30 unique images per second while 60Hz doubles the
amount of images per second.
But Wait -- I thought the human eye couldn't detect individual frames much past 24 frames per second.
-- That is technically true; the human eye is thoroughly convinced that
they are seeing a moving image even at 24 Hz. Higher Hz rating actually
makes fast-moving objects look more realistic and less blurry/jumpy.
Battling Motion Blur --
One of the outcomes of having a low Hz rating is that fast-moving
objects start to look blurry. This is actually a feature of your
display-- it is trying to compensate for the jarring nature of jumpy
image animation. A football travelling 30 yards/second would technically
only show one frame per yard when seen at 30Hz, making that throw seem
unrealistic to our eyes. The TV must therefore employ motion blur or
ruin the viewing experience.
Motion blur is a lot less distracting than the actual jumpiness of an
image, but neither motion blur nor jumpiness are desired when watching
action flicks, playing a video game, or watching sports. For those types
of video content, we highly recommend that you do not settle for 30Hz.
HDCP 2.2 Splitter Compliance
Like any active HDMI component, you're going to want to start thinking
about future HDCP versions. Unfortunately the new HDCP 2.2 standard is
not backwards compatible. That means that if you're wanting to use an
HDMI Splitter into the future that is not HDCP 2.2 compliant, it will
not work with future HDTV releases or HDMI source releases.
With the SplitDeck 4 port HDMI Splitter, since it supports HDCP 2.2, you
can be sure that it will continue to work after you get that new TV
someday. A lot of TVs being sold these days have at least one port that
supports HDCP 2.2 and is meant for full HDMI 2.0 signals
