I was trying to get a mini display port to DVI converter NOT from Apple as it was ridiculous expensive, so I went to Amazon, and then I spent ~20 minutes to do the research to figure out what is DVI-A, DVI-D, DVI-I, with single link or dual link …
It seems we are using stuffs we actually don’t quite understand, we just blindly follow some sort of instructions to get things connected, I believe this is common to most “normal” consumers, which means all products facing massive consumers should have similar characters – work without knowing too much.
Sure, we are not “normal” consumers … we are abnormal geeks, or nerd, or whatever.
