Hdmi cable no signal on tv mac

Is there a reason to get the official apple one or should Anker work? I hardly use "official" Apple adapters based mostly on their build quality - the better 3rd party manufacturers seem to do a better job. The plus side to using "official" Apple is that you have one place to look when things go wrong. I've been trying to find some place to order anker, but alas, since moving from London to Singapore last month online shopping has taken a step back Any suggestions for other brands?

What about StarTech or TrendNet? I have used both brands from time to time, but disclaimer I have never used either of these particular adapters. Thanks I will check it out. Still a bit wary given that I already tried two though. You probably don't need to replace adapter. It should work unless it is defective.
