@NickAlexeev Yeah, active adapters are almost guarenteed to work, whereas passive only work in certain cases. Back to your original question, though, most cables are passive, but you can fine some that are active if you wanted one
I'm not sure if it's relevant to displayport and dvi, but cables are usually passive adapters and adapters are usually active adapters. But it might not matter depending on the formats.. idk
If I were to work on a project, I would most likely be lead programmer. I've examined a lot of the most popular engines already out there. Developing my own would certainly give me experience as a software developer. I know that I won't exactly make a AAA engine for Crysis, but..
