2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM-28H, VM-216H away from moisture, excessive
sunlight and dust

VM-28H, VM-216H - Overview
3 Overview
The Kramer VM-28H 2 Input 1:8 HDMI Distributor and VM-216H 2 Input 1:16
HDMI Distributor are high-quality distributors that accept one of two HDMI inputs
and distribute the signal to 8/16 outputs, allowing one or more of the outputs to be
connected to receiving devices, thus making them a versatile, reliable component
in a video system. The VM-28H/VM-216H distributes signals having resolutions up
to 1080p, including all HDTV formats.
Each high-quality HDMI Distributor accepts one of two HDMI inputs, and
distributes the selected signal to:
8 outputs (the VM-28H)
16 outputs (the VM-216H)
Both machines—the VM-28H and VM-216H:
Support up to 6.75Gbps (2.25Gbps per graphic channel)
Suitable for resolutions up to 1080p, and for all HD resolutions.
Can read and store, in non-volatile memory, the EDID block, for each input
separately, from an output display device, so it can then provide the EDID
information to the HDMI source even if the display device is not connected
Let you acquire the EDID from one output, from several connected outputs
or acquire the default EDID for fast and efficient connection of the unit
Lets you use the EDID default value when no display from which to read the EDID is
connected.
Have a 19" 1U rack-mountable enclosure, and are fed from a 100-240 VAC
universal switching power supply
