I always find it difficult to plug in USB ports correctly because of it goes in only one way. DVI is the most horrible connector in existence, you could potentially bend pins badly if you connect it wrong. Are there connector out here which are as sophistacted as USB and DVI, but are perfectly symmetric, i.e, can be plugged in both ways. I read somewhere that displayport is one such connector, but looking at pictures abd my graphics card, it does not look symmetric at all.
