UHD Logo FAQ

1) What is Ultra HD?

Ultra HD (Ultra High Definition) is the future of digital display technology. It allows displaying an image four times richer than what traditional HD resolution is capable of. With more than 8 million pixels, this new technology allows displaying pictures with a depth and clarity never achieved before.

 

2) Why do I need to care about the Ultra HD logo?

DIGITALEUROPE’s intention by issuing the logo is to propose a baseline to foster interoperability in the Ultra HD market. These parameters are meant to help content producers optimise their production to these rendering parameters for a baseline Ultra HD Display and ensure that they will adequately reach the Ultra HD Display market with their content.

Our team of experts has designed a set of minimum requirements that any device carrying the Ultra HD logo has to comply with. The logo will be displayed on packages, manuals as well as on devices themselves.

Provided that source devices follow the baseline proposed by DIGITALEUROPE with these minimum requirements, the Ultra HD logo gives you the assurance that the display you are about to buy will be compatible with such Ultra HD source devices and that it will really be able to render the content of that source in Ultra HD resolution. For any parameter values beyond DIGITALEUROPE’s minimum requirements, source devices may have to provide a conformant baseline signal unless the negotiation between source device and display results in higher capability.

3) What does the Ultra HD Display logo stand for?

The logo requires that whatever content comes into the display device with an original 3840*2160 resolution will be processed and displayed with the same 3840*2160 resolution. In addition, provided that source devices follow the baseline proposed by DIGITALEUROPE through the logo’s minimum requirements, it enables interoperability with a number of Ultra HD source devices. For any parameter values beyond DIGITALEUROPE’s minimum requirements, source devices may have to provide a conformant baseline signal unless the negotiation between source device and display results in higher capability.


4) What kind of products will carry the Ultra HD Display logo?

The Ultra HD logo can be carried by any display technology that fulfils the technical requirements set by our experts. Such display devices can be any kind of screen or video-projector technology.

 

5) Can I access Ultra HD services with Ultra HD devices?

The intention behind the launch of the Ultra HD Display logo is to propose a baseline that can help source device manufacturers and content providers understand how their content is rendered on a baseline Ultra HD Display. For any parameter values beyond DIGITALEUROPE’s minimum requirements, source devices may have to provide a conformant baseline signal unless the negotiation between source device and display results in higher capability.

Provided that source device manufacturers and content providers follow this baseline, the DIGITALEUROPE logo focuses on ensuring that your display device carrying the logo is interoperable with such Ultra HD source devices and content and that it renders the content of these source devices in Ultra HD resolution, according to the minimum requirements defined by our experts. The Ultra HD Display logo is not linked with any particular service.

 

6) Can a TV set carrying the Ultra HD logo receive Ultra HD television programmes?

The DIGITALEUROPE Ultra HD logo is a display device logo and, as such, it is not about reception capabilities.

 

7) Will other devices also become Ultra HD-compatible, such as gaming consoles, video and still cameras? And will they also carry the Ultra HD logo?

 

Currently, a number of devices such as Ultra HD cameras, certain web players, computers and consoles already deliver Ultra HD content and services. As the market matures, more content should become available via Ultra HD disc players, set-top boxes and eventually broadcasting.

These will however not carry DIGITALEUROPE’s Ultra HD display device logo as these are source devices of content. The Ultra HD logo is designed for display devices.


8) Will I be able to view my existing SD and HD DVDs, home movies, photos on a UHD display carrying the DE logo?

The DIGITALEUROPE Ultra HD logo simply assures the display device’s capabilities relating to Ultra HD. Such devices will most likely also display HD and SD content, but consumers would need to check such capabilities separately. However, such legacy content can never be an Ultra HD resolution picture.

9) Why did DIGITALEUROPE choose these parameters?

With this logo, consumers are able to identify that their Ultra HD display device preserves the 3840*2160 picture with its original resolution with up to 60 frames per second and, provided that source device manufacturers and content providers follow the baseline proposed by DIGITALEUROPE through its technical specifications, the logo ensures your display device’s interoperability with such Ultra HD source content and devices. For any parameter values beyond DIGITALEUROPE’s minimum requirements, source devices may have to provide a conformant baseline signal unless the negotiation between source device and display results in higher capability.

You can find the rationale for the parameters here.

10) How can I check whether the device I am interested in is an Ultra HD display device?

You will find the logo on the packaging, user manuals or on the devices complying with the minimum technical requirements defined by our experts.

11) What is the difference between the HD-Ready, Full HDTV and the Ultra HD logos?

Over the past decade, DIGITALEUROPE has developed a family of logos for consumers to make sure that devices meet the performance levels as defined by DIGITALEUROPE for the successive generations of new technology, each time setting a new level of viewing experience. The HD-Ready logo family was developed by DIGITALEUROPE some years ago when High Definition was introduced on the market. The Ultra HD Display logo is the latest addition to the family and it aims at giving consumers the next performance level: Ultra High Definition, a picture four times richer than its predecessors.

12) Can any company use the Ultra HD Display logo?

Yes. The Ultra HD Display logo will be a registered trademark and DIGITALEUROPE will be the sole owner of the logo. However, its use will be open to any brand provided that its manufacturer signs the Logo License Agreement and uses the logo only together with products meeting at least the technical requirements defined by our experts.

13) Is the DIGITALEUROPE Ultra HD Display logo reserved for certain brands?

No. Our logo programme is open to all display device manufacturers provided that they sign our Logo License Agreement. The logo can only be used on products that comply with the minimum requirements defined in the Logo License Agreement.

14) I want to use the logo for advertising and information purposes. Where do I have to ask?

Anyone can use the UHD logo for advertising and information purposes provided that this use is complying with the UHD Logo Usage Guidelines. Especially, it is strictly prohibited to use the logo on products, product packaging or other documentation for products without a valid license agreement.

Should you have any question, please do not hesitate to contact us at logos@digitaleurope.org.

15) Does any device carrying the name UHD TV, 4K and UHD fulfill the logo requirements?

Not necessarily and that’s exactly why DIGITALEUROPE has initiated its Ultra HD logo programme. It is only for brands carrying the DIGITALEUROPE Ultra HD Display logo that manufacturers committed themselves to the technical requirements defined by our experts. Other logos are not related to DIGITALEUROPE’s programme. UHD devices not carrying the Ultra HD Display logo have to be verified against DIGITALEUROPE's baseline requirements.

It is only with display devices carrying the DIGITALEUROPE UHD Display logo the consumer is assured that devices are fulfilling the baseline requirements.

16) When will UHD broadcast and services be launched?

This will be market driven. In 2015, the first Ultra HD services were launched. A number of UHD broadcast trials in several countries over terrestrial, satellite and internet have taken and are taking place.

17) What are the benefits of such a logo for my company?

You can find description of the benefits here.

18) What is the procedure to register a brand?

You need to sign the Logo License Agreement and fulfil the minimum technical requirements set out therein.

19) Where can I find details about the parameters qualifying for the Ultra HD Display logo?

You can find all detailed parameters here.

20) Do devices qualifying for the DIGITALEUROPE UHD logo require HDMI2.0 or is HDMI1.4 sufficient?

In the case of the DIGITALEUROPE UHD logo, one or several HDMI inputs shall be capable of 3840x2160p, 50 Hz or 60 Hz, 8 bits, 4:2:0.

This mode is not part of the HDMI 1.4 specifications, but only part of the HDMI2.0 specifications.

(See HDMI 1.4 specifications and HDMI 2.0 specifications

In other words, DIGITALEUROPE UHD logo qualifying devices must implement the mode 3840*2160, 8 bits, 4:2:0, 50Hz or 60Hz according to the HDMI2.0 specifications.

NOTE1: HDCP2.2 is also a mandatory requirement for the DIGITALEUROPE UHD logo.

NOTE2: Devices with DIGITALEUROPE UHD logo may support additional modes of the HDMI2.0 specifications. Please see question 21 and 22 below.

NOTE3: Following HDMI: “Effective January 1, 2012, when marketing an HDMI Product, any references to HDMI version numbers is prohibited” (see here).

21) Why does the DIGITALEUROPE Ultra HD logo not cover HDR?

HDR (High Dynamic Range) is not part of the DIGITALEUROPE Ultra HD logo, but it may be supported by display and / or source devices.

Additionally there is no single HDR solution, there are several HDR solutions, competing in the market. Depending on the media (disc, broadcast, streaming) some HDR systems may have advantage over others. The DIGITALEUROPE Ultra HD logo aims to be agnostic to the different technologies, and focus on the core interoperability rather than on multiple add-on features.

22) What about the HDR feature on the Ultra HD Blu-Ray Discs? Will this work with devices carrying the DIGITALEUROPE Ultra HD logo?

HDR is an optional feature on top of the DIGITALEUROPE Ultra HD logo technical requirements, as well as on Ultra HD Blu-Ray Discs.

Display devices and source devices such as Set-Top-Boxes or Ultra HD Blu-Ray players are designed to communicate with each other via HDMI in order that they can establish their optimal capabilities. This enables interoperability between a number of Ultra HD devices. HDR is an optional feature for Ultra HD Blu-Ray. Therefore, if all parts of the chain (disc, player, display device) support HDR and correctly communicate their capabilities to each other, content could be enjoyed with high dynamic range. Otherwise it should default to be displayed in SDR (Standard Dynamic Range). This is also in line with the Ultra HD Blu-Ray player specification

23) What makes the difference between DIGITALEUROPE Ultra HD logo and other Ultra HD logos?

Some Ultra HD logos focus mainly on certain aspects of Ultra HD, like for example dedicated picture parameters.  DIGITALEUROPE's Ultra HD logo is focusing primarily on interoperability without compromising Ultra HD quality.

24) Does DIGITALEUROPE test devices?

DIGITALEUROPE does not test products and licenses are granted to any brand that signs a valid Logo License Agreement including the self-declaration by the licensee that their products comply with the minimum requirements set out in the Logo License Agreement. In case of infringements however, DIGITALEUROPE reserve its right to perform the necessary checking.

25) I saw a device with the Ultra HD Display logo. However, it seems not to fulfill the requirements. Where can I verify?
