Consumer Electronics Association (CEA) has announced that leading industry associations, technical organisations and retail groups have agreed to use 4K Ultra HD and 4K UHD as common terminology.

The groups – including DEG: The Digital Entertainment Group, the Custom Electronic Design and Installation Association (CEDIA), the Advanced Television Systems Committee (ATSC), the Society of Motion Picture and Television Engineers (SMPTE), the Home Theater Specialists of America (HTSA) and the NATM Buying Group – agreed to join CEA in using 4K Ultra HD as common terminology in educational and promotional efforts related to the emerging category of display products with more than eight million pixels, four times the resolution of Full HD.

“Alignment with these important and influential organisations in using common nomenclature will help accelerate growth across the exciting and rapidly-emerging new market of 4K UHD,” said CEA president and CEO Gary Shapiro.

“By working together, we will provide greater consistency and clarity across the full 4K UHD ecosystem to help guide consumers in identifying 4K Ultra HD products, services and related content.”

In July, CEA upwardly revised its sales forecast for 4K Ultra HD. CEA projects unit shipments of 4K Ultra HD displays to reach 800,000 in 2014 – a marked increase over CEA’s initial forecast of 485,000 units – earning $1.9 billion in revenue, a 517% increase over the 2013 total.

Revenue from 4K Ultra HD displays is projected to exceed $5 billion in 2015, an impressive total considering that revenue was virtually nonexistent three years earlier.
