Question: How far have owners run Cat-5e or Cat-6 cable with these extenders before seeing digital artifacts, or blotches of coarse pixels, on the screen?
Document: I first tried this product with my old(er) blu ray player with success at 1080p over a 50ft cat-6 run. When I plugged it into my cable box, however, I got handshake failure signals and when I tried the AV Receiver I got a blank screen.The product works for older devices that are not as strict with handshake rules. My new components were not so happy.
I bought this because I thought it would give me more flexibility to run cables not that thick nor expensive as those hdmi cables. So, after getting a new roof, I decided to run those cat 6 ethernet cables and use this converter. But for my totally surprise, it didn't work. No signal at all. I thought I should have tried with smaller cables, so I took a pair of cat 5e tested cables and plugged them in and... nothing again.
I just purchased a HD projector and when I used a 6 feet HDMI cable to connect the projector to my receiver for testing, the picture had white pixels all over the screen. However, when I connected the projector with the DHMI extender using 30 feet of CAT5e cables, the picture quality was as good as expected. This product really works as promised and I am glad I had the foresight to order it in advance.
I tried using these to extend the signal over cat 6 with a distance of 40' and one with a distance of 60'. Neither worked. I connected to a dvd player using two 3' cat 6 cables just to test and it worked fine. This was all brand new cat 6 in a new construction house and the cat 6 I used was average grade run through the joists. I bought powered ones and they work great. Stick with powered extenders if you're doing any sort of distance.
I recently mounted a flat screen TV out in my back patio to use when hosting sporting events. I did not want to pay for additional cable box. It was necessary to run 2 cat 5 cables to make up 1 HDMI signal. The distance was apx. 60 ft . This worked out just as I hoped and I would recommend this to anyone else.
These little extenders looked perfect for my new media wall. I replaced a shallow exterior sheetrock wall with plywood and placed a power outlet for the TV and ran 6 cat5e runs behind the wall to where my media center would be. Being a concrete exterior wall, there was only 1' of depth so I couldn't run any cable terminated to jacks except cat5 reasonably.I ordered this product along with a component extender because of their small size and "attached" pigtails to directly connect to the TV.
Be certain to pay attention to the install instructions. Needs two cables, not just one. Attempted to use 4 wire for each port before using two to run it. Didn't work, but it works beautifully with two cables. Used Cat 5e.
I have 3 lines running to this location for this TV specifically. (2) are for this HDMI device and (1) is for a USB extender. I tried to run the HDMI extender over CAT 5e, but it kept freezing the signal on the TV. So it never really worked. Then I ran a new CAT 6 for it and it works about 90% of the time. My video card pushing out the signal is an Nvidia G Force 500 series and has great capabilities for what I need.
very very good, just wrie 2 cat 5e cable, with in 30 meters support 1080p, and 3D when long then 30 meters support 720p,
Actually works but I only used it with short distance wires. Cat5 only about 10 feet. Works well with no power needed. There is some interferrence and when I turn the room lights on sometimes the screen resets.Good if you are doing a short run with high quality cat cables. Otherwise stick with powered version.I am connecting a reciever to a projector btw.
Answer: I'm running them through 50' cables and have not had any issues
