Hi folks, Please help; I am using a HDMI over cat5e extender; Neet® - HDMI Extender over Cat5 / Cat5e / Cat6: Amazon.co.uk: Electronics to send HDMI from my PC to my TV screen in another room which is only about 9 Metres away. I am using 2 of my existing installed (9 Metre) Cat5e UTP cables that are terminated with RJ45 wall plates, into which I have short Cat5e patch leads to the sender/receiver units. However, I am getting what I can best describe as black interference/freckles/snow/noise in the image (please see pic below). The receiver unit has a 5V DC power unit which appears to make no difference. I have set up a trial to test the sender by sustituting my 9 Metre Cat5e cables with 2 1M patch leads and the image is fine. After reading for hours on this (excellent) forum, I am suspecting that the 5e cables must be getting some interference or that I should have spent a bit more on the sender/receiver? The 9M cables at one point are about 4 inches from a 240V power socket In order to avoid a huge re-installation of cables; Please could anyone advise me whether a more expensive extender with 2 power supplies, such as the 'OCTAVA' could/would improve the picture? Many thanks for reading. Any help will be greatly appreciated, dingle.
