Review on Orei 4K HDMI Splitter 1x4 - 4 Port 4K Screens Duplicate 60 Hz @ 8-Bit - HDMI 2.0, HDCP 2.0, 18 Gbps, EDID Support - UHDS-104 by Michael Glassburn

Received on time and well packaged. The hub was used not only to separate the signal, but also to separate and amplify multiple HDMI output signals. ONE at the entrance, but then THREE at the exit. I wasn't sure if it would work, but it did. Build two (2) full-size arcade machines with high-resolution computer monitors that provide high signal strength. I split the signal from the Raspberry Pi into both cases and also routed it to an 80" TV to reflect what was being played. The signals didn't work because the signal was too weak, but actually worked after connecting to this device. It canceled and amplified the signal. Big. Thank you for this wonderful product. Doctor M
