Im trying to connect a Samsung 40" LCD telly to my computer using a 10 metre HDMI cable. Its connected to my PC's Nvidia GTX580 HDMI output with a cheap 10 metre HDMI v1.3 cable I bought off Amazon. The signal is intermittant and the screen will get signal for a second or two and then go blank and search for signal. This keeps repeating every couple of seconds so its unusable. Im guessing that the cheap 10m cable is too crappy to carry the 1080p 60hz signal and that theres nothing I can do short of buying a better quality cable, but if there is something that im overlooking then please could someone let me know. The strange thing is that this cable was highly rated on amazon with a lot of positive feedback, so other people must be able to get this cable to work.
