Will the next iMac — which I expect to arrive in September or October — have an HDMI (High-Definition Multimedia Interface) connector? The Mac mini, Mac Pro, and MacBook Pros do, so why not the company's best-selling all-in-one?
With Apple's increasing dominance in the areas of digital media, it seems like a good idea to have this feature on all desktop Macs. Thunderbolt and USB ports are nice. However, HDMI is getting smaller even as it gets bigger (more on that in a moment).
But let's back up. HDMI is an interface for audiovisual equipment such as high-definition television and home theater systems. It’s able to carry a bandwidth of 5Gbps (gigabits per second), which is purportedly more than twice the bandwidth needed to transmit multi-channel audio and video. HDMI provides an uncompressed, all-digital signal.
HDMI makes perfect sense for inclusion in the iMac. After all, the all-in-one is a computer that's often integrated into home entertainment systems and/or used for gaming and movie viewing.
Apple developed a Mini DisplayPort in the past. Perhaps it's time for a mini-HDMI connector. By the way, you can connect an iMac to an HDMI (as well as DVI, VGA, and dual-link DVI) device, but it requires a separate adapter.
