History
In what year was the first HDMI specification (version 1.0) officially released?
Correct! HDMI 1.0 was released in December 2002 and became commercially available in 2003. It was developed by a consortium of electronics manufacturers including Sony, Panasonic, and Philips as a successor to analog standards.
Not quite — HDMI 1.0 arrived in late 2002 and hit the market in 2003. It was a landmark moment for home entertainment, replacing bulky analog connections with a single digital cable capable of carrying both audio and video.

Standards
Which founding companies were part of the original HDMI consortium that developed the standard?
Correct! The original HDMI founders included Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, and Toshiba. Together they created a royalty-bearing standard that would go on to dominate home AV connectivity worldwide.
Not quite. The founding seven companies were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, and Toshiba. Notably, Apple was not an early backer, and Samsung joined later as a major adopter rather than a founding member.

Versions
Which HDMI version first introduced support for 4K video at 60 frames per second?
Correct! HDMI 2.0, released in 2013, boosted bandwidth to 18 Gbps and introduced 4K resolution at 60Hz. It was a crucial upgrade for the emerging 4K TV market and also added support for 32 audio channels.
Not quite — it was HDMI 2.0, released in 2013, that first enabled 4K at 60fps. HDMI 1.4 could handle 4K but only at a sluggish 30fps, which was fine for still images but not smooth enough for video or gaming.

Features
What does the 'ARC' in HDMI ARC stand for?
Correct! ARC stands for Audio Return Channel, introduced in HDMI 1.4. It allows a TV to send audio back down the HDMI cable to a soundbar or AV receiver, eliminating the need for a separate optical audio cable.
Not quite — ARC stands for Audio Return Channel. Introduced with HDMI 1.4, it was a clever addition that lets your TV send audio upstream to an external speaker system using the same cable already carrying video to the TV.

Hardware
What is the maximum bandwidth supported by the HDMI 2.1 specification?
Correct! HDMI 2.1 supports up to 48 Gbps of bandwidth, a massive leap from HDMI 2.0's 18 Gbps. This allows it to handle 8K at 60fps, 4K at 120fps, and features like Variable Refresh Rate (VRR) for gaming.
Not quite — HDMI 2.1 delivers a whopping 48 Gbps of bandwidth. That's nearly triple the 18 Gbps of HDMI 2.0 and enables next-generation features like 8K resolution, 4K/120Hz gaming, and Dynamic HDR all over a single cable.

History
HDMI was designed as a digital successor to which widely used analog video interface?
Correct! HDMI was conceived as a successor to component video, the analog standard that dominated home theater setups in the late 1990s and early 2000s. HDMI combined audio and video into one cable, something component video could never do.
Not quite — HDMI was designed to replace component video (YPbPr), the three-cable analog system common in home theaters. While DVI is a digital cousin of HDMI and shares much of its underlying technology, component video was the primary analog standard HDMI aimed to supersede.

Versions
Which HDMI version was the first to support Ethernet data sharing over the HDMI cable?
Correct! HDMI 1.4, released in 2009, introduced the HDMI Ethernet Channel (HEC), which allows a 100 Mbps network connection to be shared between devices over the same HDMI cable. It was a forward-thinking feature, though rarely implemented by manufacturers.
Not quite — HDMI 1.4 was the first version to include the HDMI Ethernet Channel when it launched in 2009. In theory it lets devices share a broadband connection without extra cables, though in practice very few products ever took advantage of this feature.
08 / 8
Features
What key improvement does eARC offer over the original ARC in HDMI 2.1?
Correct! Enhanced Audio Return Channel (eARC) introduced in HDMI 2.1 supports high-bandwidth, lossless audio formats including Dolby TrueHD, DTS:X, and object-based formats like Dolby Atmos. Original ARC was limited to compressed formats like Dolby Digital 5.1.
Not quite — the big leap with eARC is its support for uncompressed, lossless audio and object-based formats like Dolby Atmos and DTS:X. Standard ARC could only pass compressed audio, meaning audiophiles with high-end soundbars were missing out until eARC arrived with HDMI 2.1.
