Dear ENERGY STAR® Displays Partner or Other Interested Stakeholder:
The U.S. Environmental Protection Agency (EPA) welcomes your input on the enclosed Draft 2
Version 8.0 ENERGY STAR Displays specification. The proposed Draft 2 requirements reflect
feedback received on Draft 1. Comments on Draft 2 are requested by September 26, 2018. Thisletter summarizes the proposed changes.
In response to Draft 1, EPA received three sets of written comments as well as verbal feedback
during a webinar EPA hosted on May 7, 2018. EPA made a number of adjustments to thespecification as a result. These changes and EPA’s rationale for them are highlighted in
noteboxes throughout the specification. Additional responses are reflected in the Draft 1
comment response document. The Draft 2 Version 8.0 specification includes the followingchanges:Dataset
 EPA received a request to clarify which models were considered in EPA’s analysis. EPA
updated its dataset with models certified as of May 2018. EPA has clarified this analysis
by referring specifically to 'unique' models that represent a unique tested model number.
Monitors Eligibility Criteria
 Computer Monitors Energy Requirements: In Draft 2, EPA has made a slight revision
to the resolution coefficient and intercept values for the Maximum TEC equation. Further,
EPA has applied a single requirement across all size bins for an overall total dataset passrate of about 28% for ac-powered models.
 Enhanced Performance Displays: In response to comments received on Draft 1, EPA
is proposing a continuous function to apply for enhanced performance displays (EPD)
energy allowance for the variable Color Gamut instead of applying two separate discrete
allowances. EPA is also proposing to raise the minimum Total Native Resolution
requirement from 2.6 to 3.6 megapixels for models to apply the EPD allowance.
 Occupancy Sensor: EPA is proposing to remove the Occupancy Sensor allowance formonitors as there are no data indicating that the presence of such feature will draw
significantly more power.
 Touch Technology: In Draft 2, EPA proposes a revision to the energy allowance formonitors with touch technology from 20% in Draft 1 to 15% of 𝐸𝑇𝐸𝐶_𝑀𝐴𝑋 .
 Curved Monitors: In response to Draft 1 comments, EPA is proposing an allowance of
5% for curved monitors.
Signage Display Definition and Eligibility Criteria1Signage Displays Definition: In response to Draft 1 comments and to better
differentiate monitors from signage displays, EPA proposes to require that signage
displays meet three instead of two of the listed criterion and has added a fifth criterion
related to remote management. EPA also received feedback to create a specific productsubcategory for tiled displays with On Mode power requirements similar to comparably
sized single panel signage displays. In Draft 2, EPA is proposing a definition for Tiled
Display System and Maximum Tiled Configuration.

Signage Display On Mode Requirements: EPA received feedback that the On Modepower limit equation was relatively more stringent for displays over 65 diagonal inches
compared to the criteria for smaller models. In Draft 2, EPA is proposing a revised level
to recognize the top models across the spectrum of sizes, luminance, and resolution.

General Requirements for Monitors and Signage Displays
In Draft 2, EPA is proposing requirements for general user information and notifications. EPA also
added direction regarding use of forced menus and sleep mode settings. In response tostakeholder comments, EPA is not requiring energy savings features to persist across all preset
picture modes. EPA intends for these requirements to better inform consumers about which mode
meets ENERGY STAR requirements and for users to easily return to the ENERGY STAR tested
mode by selecting Default Picture Setting.
Test Method
In response to Draft 1 comments, EPA and DOE are proposing the definition of Tiled Display
System and Maximum Tiled Configuration and new guidelines for testing the maximum
configurations of tiled displays. EPA and DOE are also proposing to add USB-C to the signal
interface order of testing preference list.
Stakeholders are requested to provide comments on the Draft 2 specification no later thanSeptember 26, 2018. Please send comments via e-mail to displays@energystar.gov. Allcomments received will be posted to the ENERGY STAR Product Development website, unlessthe submitter specifically requests that his or her comments remain confidential.
On Wednesday, September 5, 2018, at 12 pm U.S. Eastern Time, EPA will host astakeholder webinar to present details on Draft 2 Version 8.0 ENERGY STAR Displays
specification and address stakeholder questions and concerns. If you wish to attend this webinar,
please register prior to the webinar.
The exchange of ideas and information between EPA, industry, and other interested parties iscritical to the success of ENERGY STAR.
