HDMI, DVI, DisplayPort and Co.: Which is the better connection?

With the new MacBook Pro models, Apple has made a bold decision: instead of a colorful mix of connectors, four Thunderbolt-3 connectors (USB‑C) are universally available. If you do not want to connect one of the few USB-C monitors at the latest, the question is: What do I need?

Apple has seldom shown its compatibility with the display connectors. Although earlier generations had a DVI connection, only the "pro" variants were available. On MacBook and Mac Mini, Apple set to mini-DVI. On mini-DVI followed the next proprietary interface: Mini Display Port. From the current standard HDMI, which was previously installed in the MacBook Pro with Retina display, the latest generation of Cupertino deviates again. The result: At least one adapter must be purchased for new devices.

VGA, DVI, HDMI

Although VGA is celebrating its 30th birthday next year, the analogue standard is almost impossible to imagine, especially from educational institutions and companies. The reason: Beamer. For a long time, these output devices have been dispensed with modern, digital connections. If you want to use your new Mac at school, university or business appointments, you should always pack a VGA adapter. These are available for devices with Thunderbolt and USB-C. In the case of presentations, it should be noted that VGA supports a maximum of 1,920 x 1,080 pixels.

The successor DVI is about twelve years younger than VGA and delivers a much better quality with up to 2,560 x 1,600 pixels, as the signal is transmitted digitally. Unlike VGA with only one standard, there are DVI in several subversions: DVI-A can only transmit analog signals, DVI-D only Digital and DVI-I both versions. The additional "dual-link" means that the data line is doubly efficient and thus allows a higher resolution. For example, the old Apple Cinema display in aluminium with 30-inch screen diagonal must be connected via dual link to achieve the maximum resolution of 2,560 × 1,600 pixels. Most DVI cables and adapters are DVI-I dual-link and therefore compatible to all standards.

The third generation display connectors – HDMI and Display Port – are closely related to DVI. This means that you can connect HDMI and DVI devices with a cheap adapter. The biggest difference is that DVI does not transmit any sound signals. While televisions almost always use HDMI, Display Port is popular in the graphics area. The two standards are more closely related than DVI and differ only by different plugs. Display Port also allows the concatenation of multiple devices, the so-called Daisy chaining. This means that a plug on the computer is sufficient for several monitors, all other monitors are connected.

Another note about HDMI: The all-rounder is also available in different versions, such as HDMI 1.4 or HDMI 2.0 a. New functions were added with each version number. For example, since 1.4, an Ethernet channel has been included that integrates entertainment devices without LAN cables on the network. HDMI 2.0 is required for HDR transmission. An overview of the possibilities your Mac has with HDMI can be found in this support document.

What works with USB-C?

Although the new MacBook Pro seems to be a consistent connection, we will have to get used to studying the fine print. For example, the Thunderbolt-3-on Thunderbolt-2 adapter, at first glance, looks like the perfect complement for transferers, since Thunderbolt 2 is compatible with Display Port to HDMI adapters. Actually. In the new adapter, this is not true, as Apple writes: "The Thunderbolt-3 to Thunderbolt-2 adapter does not support connections to the following devices: Apple display with Display Port, DisplayPort devices or accessories, such as Mini Display Port to HDMI adapters or Mini Display Port to VGA adapters and 4k displays with Mini Display Port, but without thunderbolt. Also devices that have the connection current and devices, displays and adapters with USB-C, but without Thunderbolt, are incompatible. Before you get on the road to selling adapters, make the most of a list of devices and ask our experts in the shop for which adapter is the right one. Or you can simply get an all-in-one adapter like the Minix Neo C, which covers most application cases with two USB ports, SD card slot, LAN and HDMI port. Additional USB ports as well as a headphone connector are OWCs with the USB-C dock.
