Hello, I bought an AV cable for the iphone/ipad off ebay for $20 - it is working fine, with sound and video when plugged into my TV (42" plasma) using Air Video - however, the picture quality is not as good as if play it from my laptop to TV. is this due to the 3rd party cable being bad quality build? or just ipad/air video cannot deliver HD quality videos? I want to buy the genuine cable if it in fact can deliver HD quality video, I just dont want to go out and buy the cable and it turns out quality is the same as the 3rd party cable because thats the best an ipad can do. Thanks in advance, I hope someone with prior experience will give some hints.
