Review on Zettaguard 1x4 HDMI Splitter - 1 Input 4 Output Digital Splitter with Full HD 4K x 2K, 3840 × 2160, 3D Support (ZW140) by George Saunier

Used with a TV output (HDMI) and a second output to a MINI HDMI1AV video converter. This output was then routed to multiple DVD/Audio amplifiers/other TV (RCA) inputs etc. Everything worked perfectly. I used a TENSUN HDMI 1x4 splitter but it didn't work properly. Outputting to other TVs (RCA) would split the screen and cause intermittent audio problem messages. Tensun sent me a second MINI which they said worked on their proving ground but still didn't work properly on mine. When the TENSUN power has been reset, it will solve the problem for a short period of time and then repeat the problem. Zettaguard worked great with no issues. I highly recommend this product. Worth a few dollars more.
