The DV-HAD-15 by FSR offers signal routing to five displays, up to 60Hz 1080p resolution support, 36-bit deep color, Dolby True HD, and DTS-HD. It is HDMI 1.3 and HDCP 2.1 compliant on the input and all outputs. Its front panel houses an LCD display for ease of setup and resolution confirmation, a toggle switch to control power, and two hard keys for settings adjustment. Front-panel LEDs give visual feedback as to where signals are distributed. It accepts up to 1920x1200 input resolutions. The FSR unit amplifies signals for cable runs up to 33ft. without signal loss. The unit is rackmountable and takes up one rack unit.
Gefen’s 1:4 Splitter replicates a high-bandwidth HDMI 1.3 signal across four outputs, supporting 1080p and 2K resolutions. It is equipped with EDID management. It features 3D signal pass-through and EDID management for quick integration with various sources and displays. LEDs for power, EDID selection and signal confirmation comprise the front-panel display elements. It is possible to achieve larger video displays by using two or more splitters working in conjunction with one another. Signals may also be passed via Cat-5 through use of Geffen’s accessory extender product.
The Hall Research SP-HD-4A 1x4 HDMI video splitter supports up to WUXGA PC resolutions and up to 4K HDTV resolutions to recreate images on four displays. The unit is HDMI 1.4 compatible and HDCP 1.1 compliant, can pass deep color and 3D images, and supports the gamut of HDMI audio formats available with 1.4. The unit boasts a 10.2Gbps bandwidth rating and has two LEDs, one for power and the other video. DVI adapter cables can be used to route non-HDMI HD signals from source to monitor. It is serviced via a mini USB on the back panel.
The KanexPro ProBar 1x4 1x4 HD splitter has full 1080p 3D and 4K support with a bandwidth rating of up to 10.2Gbps. It employs EDID management and is HDCP 1.3 compliant. HDMI 1.4 allows it to pass 12-bit deep color, 5.1 and 7.1 digital audio formats, and LPCM uncompressed audio. The input is located on the unit’s underside, while the front face displays the four female HDMI ports. Brackets flank the ProBar for easy wall mounting.
Kramer Electronics’ VM-114H 2x1:4 switcher/amplifier accepts signals via HDMI and twisted copper pair sources. It houses four HDMI output ports, one input via HDMI, and one RJ-45 jack. The 114 is HDMI and HDCP compliant, and allows 3D pass-through. Plug-and-play operation is ensured by EDID processing technology. Using Kramer’s proprietary twisted pair cables, the distribution range maxes out at a lengthy 330ft. Within 270ft. power can be sent via Ethernet instead of via the accessory power supply. Control is managed via an included remote, RS-232, or IR. LED indicators adorn the front fascia for confirming IR communication, power, input and output signals.
TVOne’s 1T-DA-674 4K HDMI 4K distribution amp can send four independent signals from a single HDMI source. It supports the HDMI 1.4 spec and therefore 12-bit video and 3D resolutions. It is HDCP compliant and can move up to Ultra HD 4096x2160 (4K) pixel image at 24Hz. Signal equalization allows for longer cable runs. Monitor discovery is made possible through the unit’s EDID feature.
