Review on HDMI Booster 2.0: Enhance HDMI Signal with Flashmen 4K2K 1080P 3D Amplifier - 18Gbps Bandwidth, HDCP 2.2, Up to 60m/200ft Transmission Distance by Jason Cho

When I turn on the TV, I often get the message "HDMI weak or no signal". My TIVO Bolt Vox is connected to my Hisense 55H9F TV via HDMI1 with a 3ft HDMI cable. If I switched to HDMI4 and then back to HDMI1, I usually had a connection. I installed the HDMI amplifier using a 1ft HDMI cable from TIVO to the amplifier and then a 3ft HDMI cable from the amplifier to the TV. Communication was still unstable. But when I connected the included HDMI Booster USB power cable from the amp to the TIVO USB port, the problem was resolved. I no longer get the "HDMI weak or no signal" message!
