4K2K DP/VGA USB KVM Extender over IP with Video-Wall

The 4K DP (DisplayPort) Video-Wall controller is based on Gigabit IP Ethernet, and support VGA as well. It provides the best Video quality (1080p~ 4K) and the most flexible expansion abilities (8x8 displays).
Model : DP-9521

The DP-9521 is a perfect solution for 4K2K DP (DisplayPort) with VGA/USB/IR/RS232 over Gigabit IP Ethernet. The system includes DP-9521T Transmitter (TX) and AV-9520R Receiver (RX). The TX connects to PC or Blu-ray player for the 4K2K DP (DisplayPort) or VGA source, the RX connects to display, speaker, microphone, and USB devices. 

The solution is based on the standard IP technology, the TX converts input signals (DP, VGA, Audio, USB, …) to IP packets and Multicast/Unicast to Gigabit Ethernet switch. On the other end of RXs, receiving IP packets from Ethernet switch then converts to HDMI, Audio, USB… and send to display, speaker, USB devices. The 4K2K Encoder/Decoder engine built with Scaling function, multiple RXs are flexible to be configured as Video-Wall displays. Perfect for AV Broadcasting, KVM Matrix Control, Video-Wall applications like informational displays, entertainment, boardrooms, courtrooms, medical, military, and education digital signage.
