The UHD88-EXB400R-K is a 4K HDMI Matrix extender that distributes media signals from 8 inputs to 8 distant displays. It supports video resolutions up to 4K@60Hz and 2K@60Hz and is compliant with HDMI 2.0b and HDCP 2.2 standards. This matrix extender can extend HDMI signals up to 400 feet at 4K@60Hz 4:4:4. With a video bandwidth of 18Gbps, it also allows for seamless pass-through of HDR, HDR10, HDR10+, Dolby Vision, and HLG. For displays that don't support 4K resolution, this matrix extender can downscale the resolution to 1080p for any HDBaseT output ports. This matrix extender supports a wide range of audio formats up to 7.1 channels, including LPCM, Dolby TrueHD, and DTS-HD Master Audio, with audio de-embedding (audio extraction) through analog and coaxial outputs simultaneously. It is equipped with bi-directional IR control allowing the control of the source device from the receiver's location and vice versa. Its Power over cable technology enables powering up the setup through only one power adapter connected to the transmitter. The unit can be controlled via the front panel buttons, remote control, RS-232, LAN, or the WebGUI interface. With its rack-mounted design, integration into both residential and commercial setups becomes easy.

Yes, you will be able to get a signal beyond the mentioned distance but the quality of the video decreases with increase in the distance and that too when using with shielded CAT6 cable.
Yes, you can implement the daisy chain method.
Both the ends of the CAT cable should be termed as EIA-568B & the cable should be straight & not crossed.
We recommend you to use High-Quality HDMI cables & shielded CAT6 cables.

No, this product doesn't upscale/downscale the video resolutions.
You can extend the display devices up to 400 Feet when using with a shielded CAT6 cable.
The issue might be with the CAT cable. This might be due to the external interference of the signals & CAT5e has low bandwidth as compared to the CAT6. We recommend you using shielded CAT6 cable.
If the power and link led lights does not illuminate on the RJ45 port of the transmitter and the receiver, then the transmitter & receiver might be dead.
Please contact us so that we can troubleshoot the issue.
You can upgrade the firmware by connecting the PC & this device via RS-232 cable.
Please note that this product only supports the CEC function between HDMI input & HDMI output 1.
No, optical output doesn't supports CEC due to its limitations. CEC will work only with HDMI devices.
HDBaseT is the technology used for long distance transmission of lossless signals, resulting extremely low latency & giving the best picture quality.
In normal extenders, if you extend your signals up to some extend, the quality of the signals will degrade & you may find some latency issues. HDBaseT is the lastest standard which provides extending your signals to the longer distance without degrading the quality of the signals & with 0 latency.
We recommend you using a shielded CAT6 cables for optimum performance.
Our all the extenders supports IR Frequency & the devices using RF frequency will not be compatible with our products.
The IR Blaster/Emitter should be connected to the IR out port on the Transmitter and the IR Receiver should be connected to the IR in on the Receiver.
