So it’s coming up to Christmas, people are buying new TV’s, game consoles and Blue-ray players, one thing I see in shops that really annoys me is HDMI cables been sold for astronomical prices! You could pay as much as £80 for a 5 meter HDMI cable from shops round here. If you look on Ebay you will find a cable that’s just as good and it will probably cost you around £3-5 delivered. HDMI carries a digital signal which means its either going to: A) Work B) Not work Or in very rare cases have interference of some kind. In the very unlikely event your getting interference this could mean your cable is either faulty (most likley), or another electrical device is interfering with the cable so you're going to have to invest in a more expensive cable with better insulation. This would probably only affect you if you’re running a 30+ meter cable around the outside of your house. For 99% of people out there hooking a HDMI device up to the TV with a £3 cable will be just as good as using an £80 Gold plated monster HDMI cable. I have personally got quite a few £3 HDMI cables from World of Data and there is honestly no difference between them and a friend’s £50 cable.
