DisplayPort to HDMI conversion: should I use an active or a passive adapter?

The theory of DP++ is actually quite simple: when the device detects an MI adapter attached to it, the graphics card or GPU (Graphical Processing Unit) will automatically make a translation and send HDMI TMDS signals via the video output. The pins of the DisplayPort connector are then mapped onto the HDMI pins, making the transition very simple. The system is completely plug and play, handles both video and audio, and does not need any driver to work. You even don't really need a special adapter anymore, because there are DisplayPort to HDMI cables available on the market. There is normally no loss in quality when using such a dp to hdmi cable. Note however that this simple transition only applies to single-link DVI signals, so up to HD resolution. Furthermore, when you want to connect multiple DVI or HDMI monitors to a DisplayPort output, you will need an active adapter or splitter as well. Many graphics cards can’t support DP++ output to multiple monitors. Check with the customer service of the graphics card manufacturer for the type of adapter that suits your requirements the best.
