The UHD115K extender transfers raw digital data through HDBaseT technology with zero latency and no compromise in picture quality. It supports LPCM, Dolby Digital DTS 5.1 & X, DTS-HD, Dolby Digital +, TrueHD, DTS-HD Master, Atmos. It is easy to install, works as described, and has great picture quality. It can be used with Cat5e or Cat7 cable to extend a run for a security monitor, but it only supports 1080p resolution with Cat7. POE works perfectly, but it doesn't need to be supplied to both the receiver and transmitter. It does not have VRR pass-through and cannot connect to a network switch to connect multiple units to extend to multiple monitors. It comes with a defective period of 90 days, and there were reviews of issues with dropped signals during use. CEC does not work, and it doesn't transmit on-screen display info from an AV receiver.
