3rd Party Control System Connections
Utilize an array of connections for 3rd Party Control system including RS-232, LAN, IR and USB.

Auto-Switching
Auto Switching is when an active source signal is detected via an HDMI connection and the device detects this signal source, then automatically switches to the correct input connection. This assists with basic operations eliminating the need to remotely switch the input.

4K 60 4:4:4 Support
Ultra HD refers to a TV resolution of 3,840 x 2,160 pixels. That's four times as many pixels than in a full HD TV, a total of about 8.3 million pixels. Having so many pixels means a higher pixel density, and you should have a clearer, better defined picture.

HDCP 2.2
HDCP stands for High-bandwidth Digital Content Protection, a copy prevention technology directed at HDMI connections. Version 2.2 is the latest, designed specifically to prevent illegal copying of 4K Ultra HD content.

18Gbps / HDMI 2.0
The maximum bandwidth possible due to the introduction of HDMI 2.0. Prior to HDMI 2.0 was HDMI 1.4 limited to 10.2 Gbps. The new technology permits resolutions of 4K@60Hz (4:4:4) while still capable of transmitting audio and control signals simultaneously.

USB Data Transfer
There are multiple USB standards based on release date of new USB technologies. Here is a reference regarding speeds and transfer rates. Make sure your source and destination devices are compatible for proper operation.

Interface

RS-232
Serial communication Interface connection standard commonly utilized to control equipment via computers and control systems using a common DB9 pinout.

TCP/IP / Ethernet / LAN - RJ45
Connection port for communicating to devices via a Network using IP (Transmission Control Protocol/Internet Protocol) transmitting data packets to and from a Server/Computer.

IR EXT
Permits the use of an IR Receiver for remote extension providing control for a device using a 3.5mm mini jack.

L/R Audio Out
A connection in the form of a 3.5mm mini jack or Pin connector that enables audio extraction from HDMI Input to another device like Active Speakers or an Amplifier to distribute sound, typically only supports Mono and or stereo audio formats.

Digital Coax Out
A connection in the form of a single RCA port that enables audio extraction from HDMI inputs to another device like Active Speakers or an Amplifier to distribute digital quality audio including surround sound formats such as, Dolby Digital, Prologic, 5.1/7.1 and DTS.

EDID DIP Switch
Extended Display Identification Data (EDID) manual switch providing the ability to match the source devices resolution the Display's video resolution.

IR Input
A connection in the form of a 3.5mm mini jack or Pin connector responsible for receiving IR signals from devices and sources using a set of commands for control in pulse form using infra-red spectrum.

IR Output
A connection in the form of a 3.5mm mini jack or Pin connector responsible for sending IR signals from a device to other device sources using a set of commands for control in pulse form using infra-red spectrum.

HDMI Input
A digital port connection providing an interface for HDMI cables to plug into any audio/video source, such as a set-top box, or DVD player usually found on TV Displays, Matrix Switchers and other video distribution devices. (HDMI 1.4, 2.0, 2.3 are numbers representing types of resolutions supported).

HDMI Output
A digital port connection providing an interface for HDMI cables to plug into any audio/video source, such as a set-top box, or DVD player usually found on AV Receivers, TV Displays, Matrix Switchers and other video distribution devices. (HDMI 1.4, 2.0, 2.3 are numbers representing types of resolutions supported).

HDBaseT
A global standard for the transmission of ultra-high-definition video & audio, Ethernet, controls, USB and up to 100W of power over a single, long-distance, cable using Category cable such as Cat5/5e/6/6a/7 with RJ45 connectors.

ARC (Audio Return Channel)
Connection typically in the form of SPDIF (Fiber Optic) port on a Display responsible for returning audio from the HDMI input in which a Source is connected providing sound back to a Surround Sound receiver to amplifier for audio distribution.

HDR10/HDR10+
(High Dynamic Range) Enhances picture quality on displays by Producing 1000 NITS of peak brightness, whereas HDR 10+ supports up to 4000 nits. In addition, both the standards support 10 bit color depth, which is approximately 1024 shades of primary colors.

4K
Ultra HD, refers to a TV resolution of 3,840 x 2,160 pixels. That's four times as many pixels than in a full HD TV, a total of about 8.3 million pixels. Having so many pixels means a higher pixel density, and you should have a clearer, better defined picture.

8K
Highest Resolution offered with 2X more pixels than 4K with a width of approximately 8000 pixels (7680 x 4320) on displays.

USB - A
