solutions Say you have a brand new 4K/60 Hz HDTV in one room, but want to also connect your Blu-ray player or satellite box to an older 1080p TV in another room. The B127A-004-BH is backward compatible with 4K/30 Hz and 1080p resolutions via automatic switching, allowing each connected monitor to display video at its maximum resolution. Local HDMI Port on Transmitter Supports 4K @ 60 Hz Resolution and Cascading  To monitor the video signal being extended to the receiver, connect a 4K display to the splitter’s local HDMI port with a user-supplied HDMI cable. This port does not support multi-resolution capabilities, so the connected monitor must also support 4K/60 Hz to function properly. Add even more displays to an installation by connecting an additional B127A splitter unit (sold separately) to the port. Built-In PoC Technology Provides Receiver Power to Avoid Bulky External Power Bricks Power over Cable (PoC) technology powers the connected receivers over Cat6 cable. LEDs indicate when the system is receiving power and a signal is being transmitted. PoC lets you avoid the hassle of a bulky power brick and gives you the freedom to place the receivers where needed without worrying about finding a nearby AC outlet. Plug-and-Play Operation for Quick Setup and Immediate Use The splitter works right out of the package with no software required. Mounting hardware is included for installing it on a wall, pole or 19-inch rack. Connect the splitter to an HDMI source device with a user-supplied HDMI cable (such as Tripp Lite’s P568- or P569-Series). Then, connect the splitter to Tripp Lite B127A-Series remote receivers with user-supplied Cat6 cable (such as Tripp Lite’s N202-Series). TAA-Compliant for GSA Schedule Purchases The B127A-004-BH is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
