Review on 🔌 OREI 1x4 HDMI Extender Splitter: High Definition CAT6/7 1080P Over Single Cable - Long Range - IR Remote & EDID Management - Loop Out - Low Latency by Christopher Pfaffe

We use this (or at least try) for monitoring 8 screens. No cable is longer than 100 feet. Also, there is no signal from the device on the TV. The receiver lights up like it has power, but there is no data. There were no instructions in the box and if you look at the company's website there is no information (check their FAQ section if you want a laugh). We use this type of extension cords all the time for customers, but this is the first and last time we try this brand. After playing around with the DIP switches on the receiver side I got one of them to display video but it had dead pixels all over the frame. The output loop on the device looks good. I suggest you look at MANY other Revain options and avoid OREI. If you look at the support page on their website you'll see that if you have a problem (like we're having) you'll have to pay shipping to and from them to look at the device. They also charge a restocking fee when you return the device. With such a support policy it is obvious that they do not stand behind the product they make and I would not trust such a company.
