[[File:DisplayPort16.png]]DisplayPort first appeared in 2006, while HDMI came out in 2002. The DisplayPort and HDMI digital signals use bitrate encoding of some form — 8b/10b for most of the older standards, 16b/18b for HDMI 2.1, and 128b/132b for DisplayPort 2.0. 8b/10b encoding for example means for every 8 bits of data, 10 bits are actually transmitted, with the extra bits used to help maintain signal integrity (eg, by ensuring zero DC bias). [[File:HDMI-DisplayPort.jpg]]HDMI is a licensed brand and specification, whereas DisplayPort is a royalty-free standard. DisplayPort has typically offered higher maximum bandwidth than HDMI. While HDMI 2.1 does beat DisplayPort 1.4, DisplayPort 2.0 is faster yet. The original Display 1.0-1.1a spec allowed for RBR (reduced bit rate) and HBR (high bit rate) cables, capable of 5.18 Gbps and 8.64 Gbps of data bandwidth, respectively. DisplayPort 1.2 introduced HBR2, doubled the maximum data bit rate to 17.28 Gbps and is compatible with standard HBR DisplayPort cables. HBR3 with DisplayPort 1.3-1.4a increased things again to 25.92 Gbps, and added the requirement of DP8K DisplayPort certified cables.Unfortunately for consumers, DisplayPort also fully supports [[High-bandwidth Digital Content Protection (HDCP)]] just like HDMI. == Universal Serial Bus aka USB ==six most common types#Type-A -- rectangle type on computers #Type-B -- device connectors almost-square#Mini-USB -- also known as Motorola connector, PlayStation 3 controller, MP3 players#Micro-USB -- Android phones #Type-C -- Newer Android phones, modern laptops and smartphones, including MacBooks, Pixel phones, and controllers for the PlayStation 5#Lightning -- Apple's proprietary connector for the iPhone, AirPods, some iPad models[[File:USB-types-2x-1024x334.png]][[File:usbchart1210789874.jpg]][[File:usb3162700290.jpg]]
