Tripp Lite DisplayPort to HDMI Extender Kit - 150 Ft - 1 Input Device - 1 Output Device - (B150-1A1-HDMI) - Cable Adapters and Couplers

I've purchased 4 of these adapters for work to display user and product specs for different systems on an upstairs monitor. The product works great until something causes power to shut off in the building suddenly. Once this happens, nothing I have tried can get these things working again.

I give it one star because it works when you run a single cat5 cable from transmitter to receiver. Any additional connection renders this product useless. I bought it for a conference room. I want to connect a laptop on the table with a TV on the wall without laying a cable on the floor. I intended to use a cat5 connection in the floor that simply runs to another cat5 connection on the wall behind the TV. I tried many things, but the bottom line is this device only works with one cable from transmitter to receiver. I called Tripp-Lite tech support, and their message is that they didn't expect it to work unless there is a single direct connection. I understand that having it go through a Switch or Router might cause a problem. But I think it's unreasonable to sell this product expecting customers to not use any additional connections without disclosing it; it seems unethical to me. And of course, they are not able to take the product back. I've bought many power strips and battery backups; I have a Tripp Lite rack enclosure-all good products. This product though, lacks a full disclosure of its abilities (or rather disabilities). Again, I'm very disappointed in Tripp-Lite.

I have used a Tripp Lite VGA splitter/extender over CAT5 for six years. The device was starting to give out so I look at options. Going to DisplayPort made sense in terms of where display is going while it was more practical than the HDMI options in terms of price and requirements. With a new graphics card (with two DisplayPort jacks) and monitors (replacing fairly old ones) I upgraded my setup with the DisplayPort to HDMI extender. My setup involves mirroring the family desktop monitor from the basement office to the kitchen. At first I had serious problems getting the second monitor not consistently showing (hence four stars instead of five). Hours of troubleshooting I concluded the problem was with following directions: powering the transmitter from a USB port on my desktop tower was causing some sort of conflict with the transmitter or the graphics card. Don't know exactly but once I plugged the USB cable into a adapter brick everything has worked flawlessly ever since. going to a pure digital signal from VGA signal is very nice. It's also nice that Windows can accurately scale the resolution of the screens, whereas it never quite got the VGA correctly and I had to choose an aspect ratio that was not consistent with the specs for my old monitors.
