Mini DisplayPort Fades From New Computers, but DisplayPort Standard Endures

Mini DisplayPort has largely disappeared from new computers as Thunderbolt 3 and USB-C took over video, audio and data duties, but the DisplayPort standard remains important for high-end monitors and graphics cards, according to Engadget.

Apple announced Mini DisplayPort in 2008 to replace interfaces such as VGA and DVI with a single, slimmer connector. It appeared on most Mac models for several years. The connector is a smaller version of full-size DisplayPort; both carry video and audio over one cable and share the same core specifications. Apple chose the smaller version because it fits better on computers such as MacBooks and the Mac mini.

DisplayPort offers much higher bandwidth than older connectors like DVI and VGA. Depending on the generation, it can handle resolutions up to 8K and beyond, at high frame rates such as 144Hz or more depending on resolution, Engadget reported. Older connectors struggle above 1080p.

When Thunderbolt emerged, its first two iterations used the Mini DisplayPort connector. A standard Mini DisplayPort only carries video and audio, while Thunderbolt also supports high-speed data transfers. That let the same connector handle video, audio and data, which suited accessories including Apple's Cinema Display. In late 2015 and 2016, Thunderbolt 3 arrived and switched to USB-C. Apple and other PC manufacturers quickly moved to USB-C or HDMI, leaving Mini DisplayPort behind.

USB-C has since become the standard for nearly everything. It can support high-speed data transfer, video, audio and even the Thunderbolt protocol in one small, reversible connector. Not every USB-C port handles the same tasks, but some version of the port appears on almost every device. USB-C also supports DisplayPort Alternate Mode, meaning compatible USB-C cables and ports can carry the same DisplayPort signal. That removes much of the reason for PC makers to push consumers toward a Mini DisplayPort-to-DisplayPort cable when a USB-C-to-DisplayPort cable can do the job.

DisplayPort itself is not gone. Older hardware with Mini DisplayPort, such as past laptops and graphics cards, can still connect to a modern monitor with a Mini DP-to-DP cable because the protocol is the same. New hardware continues to use the full-sized DisplayPort connector, which remains common on many high-end monitors and graphics cards.

HDMI has improved and can now transmit video at very high resolutions, but DisplayPort remains a standard for very high resolutions and refresh rates, such as 4K at 240Hz. HDMI 2.1 offers up to 48 Gbps of bandwidth, while DisplayPort 2.1 can reach 80 Gbps, according to Engadget. HDMI 2.2 offers 96 Gbps and may close part of the gap once compatible devices are widely available.

There are caveats with older hardware. VR headsets can be picky about their video signal and do not always work well with Mini DisplayPort when an adapter is used. Apple also states that the old Apple Cinema Display does not work through a Thunderbolt adapter. Engadget notes that it still may be worth trying if the right cables are available.

Editor's Summary

Mini DisplayPort has been phased out of new computers as Thunderbolt 3 and USB-C became preferred connectors for video, audio and data, according to Engadget. The DisplayPort standard still matters for high-end monitors and graphics cards, where bandwidth and refresh rates remain important. Users with older Mini DisplayPort hardware can often connect to modern displays with the right cable, though some devices may not work through adapters.
