Dear ENERGY STAR® TV Partner or Other Interested Stakeholder:
The U.S. Environmental Protection Agency (EPA) is pleased to share the ENERGY STAR Version 9.0 TVs
Final Draft Specification. This Final Draft contains changes made in response to written comments received
regarding the Draft 2 specification, the Limited Topic Proposal (LTP), and to account for the continued progress
made towards finalizing the Consumer Technology Association’s CTA-2037C: Determination of Television Set
Power Consumption test procedure, which is referenced by the specification.
These changes are highlighted in noteboxes throughout the specification and outlined below. Stakeholders
may submit written comments on this Final Draft by December 22, 2021.
Overview of the Final Draft Specification
EPA received generally positive feedback regarding the approach and criteria levels proposed by the Draft 2specification. Several stakeholders expressed support for the following aspects of the Draft 2:•Standby-Active Mode Power requirement of 1 W,

•Average On Mode Power approach, which allows manufacturers added flexibility in programming
Preset Picture Settings (PPS) so long as On Mode requirements are met on average, and•The introduction of lower luminance thresholds for certification, which allow manufacturers to set default
backlight levels however they wish while eliminating the incentive to provide overly dim settings to meetcriteria.

As such, EPA maintained these proposals for this Final Draft.
In response to the Limited Topic Proposal (LTP) published in September 2021, regarding the High-ContrastRatio (HCR) adjustment factor, EPA received feedback requesting additional clarification for the definition of an
HCR Display included in the specification. As such, the definition for an HCR Display included in this Final
Draft contains the requirement that the display must be capable of controlling pixels individually, which is an
integral factor in their ability to offer such high contrast ratios.
Also in response to the LTP, EPA received feedback and data regarding the proposed value of the HCR
adjustment factor. EPA has retained the proposed AFHCR value of 1.12 for this Final Draft specification. Testingdata used to develop the value proposed in the LTP indicated that the current value of 1.12 will allow only themost efficient HCR-capable models to earn certification.
Testing data submitted in response to the LTP indicates that some of the most recently developed HCR
Display models would be able to meet requirements with a smaller adjustment factor. The observed increases

in efficiency between this sample of adjacent model years support EPA’s belief that there are readily available
means by which manufacturers can increase efficiency and reinforces the viewpoint that by making ENERGYSTAR certification obtainable for these products, there is an incentive for manufacturers to do so. Additionally,
these models observed to meet requirements after some redevelopments are significantly more efficient thancomparable models that have not been updated, which supports the notion that the models that have beenengineered to perform well above the baseline should be recognized. EPA has maintained the 1.12 value as
further restriction of the adjustment factor risks making certification unobtainable for the most efficient HCRcapable models, thus eliminating the incentive to increase efficiency.
Finally, EPA acknowledges that the CTA-2037C: Determination of Television Set Power Consumption test
procedure referenced in the Draft 2 is now complete and available to the public for reference. Included in thisFinal Draft are several amendments to calculation methodologies that follow the changes made to CTA-2037C
between the time of Draft 2’s publication and finalization of the test procedure.
