HDMI	DisplayPort
1. HDMI 1.0: This was the initial version introduced in 2002. HDMI 1.0 supported a maximum resolution of 1920x1200 pixels at 60Hz and had a bandwidth of 4.95 Gbps. It also supported 8-bit color depth and two audio channels. Supports audio. It introduced the capability to transmit both high-definition video and multi-channel audio signals over a single HDMI cable.	1. DisplayPort 1.0: This was the initial version introduced in 2006. It supported a maximum resolution of 2560x1600 pixels at 60Hz and provided a bandwidth of 8.64 Gbps. Supports audio, provides support for up to eight digital audio channels, allowing both video and audio to be transmitted through a single DisplayPort cable.
2. HDMI 1.1: Released in 2004, HDMI 1.1 added support for DVD-Audio, a high-quality audio format commonly used on DVDs.	2. DisplayPort 1.1: This version was released in 2007 and added support for High-Bandwidth Digital Content Protection (HDCP), a copy protection mechanism used for protected content. It also allowed for multiple audio streams to be transmitted simultaneously.
3. HDMI 1.2: Introduced in 2005, HDMI 1.2 brought a few enhancements. It added support for One Bit Audio, a high-quality audio format used in Super Audio CDs (SACDs). HDMI 1.2 also introduced support for Consumer Electronics Control (CEC), which allows interconnected HDMI devices to control each other through a single remote control.	3. DisplayPort 1.2: Released in 2009, DisplayPort 1.2 brought significant improvements. It increased the maximum resolution to 3840x2160 pixels (4K) at 60Hz or 2560x1600 pixels at 120Hz. It also introduced Multi-Stream Transport (MST), which enabled the daisy-chaining of multiple displays using a single DisplayPort connection. Additionally, it increased the bandwidth to 17.28 Gbps, enabling support for higher color depths, refresh rates, and multiple displays.
4. HDMI 1.3: Released in 2006, HDMI 1.3 brought significant improvements in terms of bandwidth and features. It increased the maximum bandwidth to 10.2 Gbps, allowing for higher resolutions and refresh rates. HDMI 1.3 supported resolutions up to 2560x1600 pixels at 75Hz and introduced support for Deep Color, which allowed for increased color bit-depths beyond the traditional 8-bit. It also added support for Dolby TrueHD and DTS-HD Master Audio, high-definition audio formats used in Blu-ray discs.	4. DisplayPort 1.3: Introduced in 2014, DisplayPort 1.3 further increased the bandwidth to 32.4 Gbps, allowing for even higher resolutions and refresh rates. It supported resolutions up to 7680x4320 pixels (8K) at 60Hz or 3840x2160 pixels (4K) at 120Hz. DisplayPort 1.3 also introduced support for Display Stream Compression (DSC), a visually lossless compression algorithm, which enabled higher resolutions and refresh rates without sacrificing image quality.
5. HDMI 1.4: Introduced in 2009, HDMI 1.4 added several new features to support emerging technologies. It introduced support for 3D video, allowing for the transmission of 3D content from compatible devices to 3D-enabled TVs. HDMI 1.4 also supported an Ethernet channel, which allowed for an internet connection to be shared between HDMI devices via the HDMI cable. Additionally, it added an Audio Return Channel (ARC), enabling the transmission of audio from a TV's built-in tuner or other sources back to an AV receiver without the need for a separate audio cable.	5. DisplayPort 1.4: Released in 2016, DisplayPort 1.4 maintained the same maximum resolution and refresh rate as DisplayPort 1.3 (8K at 60Hz or 4K at 120Hz) but introduced improved support for High Dynamic Range (HDR) and increased the maximum number of audio channels to 32. It also added support for the Display Stream Compression 1.2 standard.
6. HDMI 2.0: Released in 2013, HDMI 2.0 provided a substantial increase in bandwidth to 18 Gbps. This allowed for higher resolutions and refresh rates, including support for 4K resolution at 60Hz. HDMI 2.0 also introduced support for High Dynamic Range (HDR), which enhanced the color and contrast range for more vibrant and lifelike images. It maintained compatibility with previous HDMI versions and cables.	6. DisplayPort 2.0: This is the most recent version, announced in 2019. DisplayPort 2.0 provides a significant upgrade in terms of bandwidth, delivering up to 80 Gbps. This allows for even higher resolutions, refresh rates, and color depths. It supports resolutions up to 16K (15360x8460 pixels) at 60Hz or 8K at 120Hz with full HDR support. DisplayPort 2.0 also introduces Forward Error Correction (FEC), which improves the reliability of data transmission.
7. HDMI 2.1: Announced in 2017 and widely adopted in newer devices, HDMI 2.1 brought significant enhancements. It increased the bandwidth to 48 Gbps, enabling support for higher resolutions, refresh rates, and color depths. HDMI 2.1 supports resolutions up to 10K at 120Hz or 8K at 60Hz. It also introduced Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Auto Low Latency Mode (ALLM), features that improve gaming performance by reducing lag and screen tearing. Furthermore, HDMI 2.1 added support for Enhanced Audio Return Channel (eARC), allowing for high-quality audio formats such as Dolby Atmos and DTS:X to be transmitted over HDMI.
