Why on earth would Apple choose to adopt a new interface when we already have standards like HDMI? It costs $100 to adapt Apple’s Mini DisplayPort back to Dual-Link DVI, bad news for people wanting to connect their New MBPs to older Displays. Look at the bright side though;

• The mini Display port is 4x smaller then a standard DVI port.
• Mini DVI and Micro DVI can only support resolutions up to 1920×1200, whereas mini DisplayPort can push resolutions up to 2560×1600
• Unlike HDMI, DisplayPort is 100% open which means no license fees for using it in your product. This means Apple can pass the savings on to you.
• The DisplayPort specifications allow for daisy changing multiple monitors

It’s not all gold and roses though, lack of audio support from the mini version of DisplayPort and difficult conversion to HDMI makes for some slight headaches when trying to use your new Mac with older technology. It’s not perfect yet, but continued support and development can produce a solid interface.
