General User Information: The product shall ship with consumer informational materials located ineither (1) the hard copy or online electronic user manual, or (2) a package or box insert. Thesematerials shall include:i.
ii.

Information about the ENERGY STAR program;Information on the energy consumption implications of changes to as-shipped TV/HTD
configurations and settings, including the implications of software or firmware updates; andiii. Notification that enabling certain optional features and functionalities (e.g., instant-on), may
increase energy consumption beyond the limits required for ENERGY STAR certification, as
applicable.

215
216
217

Note: EPA has included a requirement in Section 3.2.2.ii. that information must be provided regarding theenergy implications of changes to default settings made via a software/firmware update that may change
the power consumption of the product.

218
219
220
221
222

3.2.3

Energy Saving Features: A TV/HTD may not be certified with any detectable or undetectableenergy saving features that are enabled when tested unless that feature provides comparable
energy savings during typical viewing experiences (i.e., the duration of a variety of popular
programming). This prohibition applies irrespective of whether the function’s primary or intended
purpose is energy savings. Further, this applies to features that may be downloaded in the future.

223
224

3.2.4

Forced Menu: For any product that includes a Forced Menu where consumers are provided a
choice of Home Configuration or Retail Configuration at initial start-up:

225
226
227
228
229
230
231
232

i.

ii.

Upon selection of Retail Configuration, either (1) display a second prompt requiring the user
to confirm the choice of Retail Configuration, or (2) display information on the start-up menu
that the Home Configuration is the setting in which the product qualifies for ENERGY STAR.
If option (2) is selected, additional detail about ENERGY STAR certification and energy
consumption expectations shall be included in printed product literature and on the productinformation page on the Partner’s website.
Partners may use alternative terminology if approved by the U.S. Environmental Protection
Agency (EPA).

233
234
235

Note: EPA proposes removing the requirements in Version 8.0 Sections 3.2.6 (Manual Adjustments to TV
Parameters) and 3.2.7 (Special Functions) because the proposed test procedures in Section 4.4 of thisdocument require the energy saving feature ABC to be disabled during testing.

236
237
238
239

As TV/HTDs are required to meet Standby Mode power limits in all three of the PPSs tested (per Section
3.4), a product that achieves certification will meet criterion in a range of PPSs. Therefore, EPA proposes
to delete the requirement to indicate to consumers which standby settings were certified to ENERGY
STAR.

240
241
242
243

Because Thin Client and MVPD-ready Information technology appears to be rapidly giving way to appbased methods of content streaming, EPA proposes to delete requirements previously placed on suchproducts. If it is believed that Thin Client capabilities are still prevalent in the market or will be again,
manufacturers are invited to submit such relevant information for consideration.

244
245
246
247
248

3.2.5

Standby-Active, High Mode Capability: TV/HTDs with Standby-Active, High Mode shall
automatically return to the as-tested Standby-Active, Low Mode or Standby-Passive Modefollowing a manufacturer firmware update or other maintenance operation in Standby Active, HighMode within a period less than or equal to 15 minutes from the completion of said
update/maintenance operation.

3.3

250
251

The following On Mode requirements are based on measurements from a series of On Mode tests
outlined in Section 4.4 that are designed to measure how efficiently a TV generates light.

252
253
254
255
256
257
258

Note: The ENERGY STAR dataset used to develop both On Mode and Standby Mode criteria consistedof over 90 4K LED and 11 high contrast ratio (HCR) models that were available for purchase in 2019 at
popular retail locations. The On Mode adjustment factors developed for HCR models were based on thisdataset. The adjustment factors for HD and 8K models were established by using the California Energy
Commission database to compare HD and 8K model power consumption to the power consumption of 4K
models. The proposed criteria outlined in Sections 3.3 and 3.4 achieve an estimated 25% model-based
pass rate across EPA’s dataset.

3.3.1

262

264
265
266
267

On Mode Requirements

For all TV/HTDs, On Mode Power (POA) metrics, as determined by Section 4.4: On Mode Tests
for All TV/HTDs, shall be less than or equal to the corresponding Maximum On Mode Power limits(POA_ MAX) as shown in Equations 1, 2, and 3, and are subject to the following requirement:i.

Products shall meet the On Mode Power Requirements for all three Preset Picture Settings
indicated by Equations 1, 2, and 3: Default, Brightest, and Default HDR10. Should a TV nothave an HDR10 Preset Picture Setting, it will not be subject to that test and shall only meetthe Default and Brightest Preset Picture Setting criteria. Should a TV have a Default SDR
Preset Picture Setting that is also the Brightest Selectable SDR Preset Picture Setting, thenthe same test result can be used for 𝑃𝑂𝐴_𝐷𝑒𝑓𝑎𝑢𝑙𝑡 and 𝑃𝑂𝐴_𝐵𝑟𝑖𝑔ℎ𝑡𝑒𝑠𝑡 .

268
269
270
271
272
273
274
275

Note: EPA is proposing these On Mode Power (POA) requirements to evaluate performance-based
metrics representative of the efficiency with which TV/HTDs produce light in typical picture settings that a
consumer may choose to employ. Current research shows that a majority of devices are either left in theirdefault setting or have been put into their brightest setting. As a result, testing in both of these settings ismore representative of real-world TV use than testing exclusively in the default setting. Additionally, withbroadcast TV transitioning to HDR, the HDR10 PPS (HDR10 being a proxy for all HDR content for now,as it is the minimum specification) is expected to be much more commonly used. Thus, this will be a third
PPS required to be tested and meet criteria for purposes of certification.

276
277
278

The On Mode Power metrics obtained by testing these three PPSs per Section 4.4 and evaluated per the
On Mode Power Requirement equations are separate from the On Mode Power metric obtained per theFederal Test Procedure, labeled POn, which must also be reported for certification under ENERGY STAR.

A is the viewable Screen Area of the product in square inches;
DL is the Dynamic Luminance measured for the Preset Picture Setting;
Adjustment factors are applied to TV/HTDs that possess the resolution characteristics for which eachis named (e.g., A TV/HTD with the resolution of an HD display incorporates the HD adjustment factor
into the appropriate On Mode Power Requirement equation);
The 4K_HCR adjustment factor applies to TV/HTDs with a 4K resolution and a contrast ratio of atleast 1,000,000:1;
For TV/HTDs possessing a resolution other than those with a determined adjustment factor,
incorporate the adjustment factor of the horizontal resolution immediately below it (e.g., A display witha 5000x2900 pixel resolution should apply the 4K adjustment factor into the appropriate On Mode
Power Requirement equation); andFor TV/HTDs with a resolution less than that defined by the HD Display definition (i.e. 720p), the HD
adjustment factor shall apply.

Note: EPA has developed these performance-based efficiency limits for the Default SDR, Brightest SDR,
and Default HDR10 PPSs to promote the development of TVs that generate light more efficiently. Limit 1,
the performance-based efficiency limit, promotes the development of TVs that generate light more
efficiently in terms of power per luminance x area. Limit 2, the power cap limit, provides a mechanism tolimit extremely bright backlight settings for the three PPSs tested.

The proposed HD, 4K, and 8K Adjustment Factors in Table 2 adjust the Maximum On Mode Power limit
according to the power consumption of several distinct classes of display resolution. EPA developed
these Adjustment Factors by determining how energy consumption varies with different screen
resolutions. In examining the current market, it appears that the majority of TV/HTDs for sale consist of
those with resolutions for which the adjustment factor has been tailored. If there is reason to expect that
there should be an increase in the market share of other resolution standards (e.g. 720p, 2K, etc.),
stakeholders are invited to provide such relevant information for consideration.

The High Contrast Ratio (HCR) Adjustment Factor (4K_HCR) was derived after testing HCR capable 4K
models. There are not enough HD or 8K models with HCR capabilities available to consumers from whichto assess the need for separate HD_HCR or 8K_HCR Adjustment Factors. EPA expects that as themarket for 8K TVs grows, more HCR capable models will become available. However, until enoughmodels are available to form a dataset, an 8K HCR Adjustment Factor cannot be determined. If there isdata available, EPA would appreciate information regarding the need for a separate 8K HCR adjustment
factor (currently an 8K HCR capable TV would qualify for the 8K adjustment factor). Stakeholders areinvited to provide additional data for consideration in developing appropriate Adjustment Factors as partof their written feedback to Draft 1. Also, EPA understands that Quantum Dot Color Conversion
technology has the potential to significantly reduce energy consumption of HCR TVs. EPA requests
additional information about the magnitude of savings and market timing for this technology, which may
cause EPA to reconsider the need for an HCR adjustment factor.

EPA believes these performance-based criteria will encourage more efficient product design through the
adoption of efficient components (e.g., LEDs, films, power supplies, etc.) and energy saving features(e.g., local dimming). These criteria also eliminate the need for luminance requirements, allowing for awide range of luminance settings while ensuring that luminance is provided efficiently. In doing so, thisapproach provides manufacturers more flexibility and an incentive to deliver light efficiently (i.e., more
efficient TVs can be brighter than less efficient TVs). As a result of this proposal, EPA has removed
Section 3.6 Luminance Requirements from Version 8.0 for Version 9.0.

TV/HTDs must meet Additional Standby-Active, Low Mode power requirements in each of thethree Present Picture Settings identified in Section 3.3.3.i: Default SDR, Brightest SDR, andDefault HDR10 for both tests without and with a smart speaker (4.6.1 and 4.6.2,
respectively).

376
377
378
379

Note: Standby-Passive testing is intended to be conducted per the Federal Test Procedure and thecriteria proposed here remains unchanged. However, the Additional Standby-Active Low Mode is
proposed to be tested according to the Federal Test Procedure and the additional testing outlined in
Section 4.6.

380
381
382
383

EPA is interested in exploring the relationship between different PPSs and Standby Mode power
consumption. If standby power consumption does not vary based on PPS employed while in On Mode,
the repetitive Standby Mode testing of TV/HTDs in different PPSs may be unnecessary. As a result, EPA
welcomes stakeholder data relevant to the relationship between Standby Power and the PPS enabled.

EPA believes this will capture anychanges in power consumption resulting from software updates, while eliminating some test burden. Also,
EPA has removed the additional HDR upscaling and luminance tests since EPA is now requiring testingin the HDR10 picture setting, as well as measuring dynamic luminance per the tests in Section 4.4.

The On Mode tests require the measurement of Dynamic Luminance with a camera photometer –equipment and set-up requirements are defined here. Dynamic Luminance shall be measured with amonochrome camera photometer that meets the following requirements:
i. Capable of measuring screen-average luminance (in cd/m2) during video test clip play with
TBD% accuracy as measured by TBD;
ii. Able to sample data at 6 fps without dropping data between frames and to log data at 1
second intervals;
iii. Minimum resolution of 720 x 540 pixels;

Note: The camera photometer approach was developed in conjunction with DOE and is being reviewed
by IEC for consideration in future revisions of IEC 62087. Camera photometer performance evaluation isin progress. Preliminary results suggest that the use of color correction factors can achieve low cost andhigh accuracy measurements. The above accuracy metric labeled as TBD will be specified once theappropriate color correction factors are determined. EPA expects these metrics to be included in the Draft
2 Specification.

The camera photometer shall be positioned at a distance of 1.0 to 1.1 times the TV/HTD
screen diagonal dimension away from the center of the screen, pointing at the center of thescreen. For example, the camera photometer should be placed 55” to 60.5” away from a 55”
TV.
ii. The camera must be stabilized before testing is conducted, requiring a 60-minute warm-up(dependent on the model), and set to log data at 1 second intervals.
iii. The camera shall be focused on the screen and the appropriate vignette correction file forthat focus distance must be used for the test.

All testing shall be performed with ABC and Motion Detection Dimming turned off. The following test
sequence shall be used to determine power and luminance measurements. Measure and record theaverage power (POA) and dynamic luminance for the following tests:i. SDR Default Preset Picture Setting with IEC 62087 Ed. 3.0 Blu-ray DiscTM Dynamic
Broadcast-Content Video Signal.
ii. SDR Brightest selectable Preset Picture Setting with IEC 62087 Ed. 3.0 Blu-ray
DiscTM Dynamic Broadcast-Content Video Signal.
iii. HDR10 Default Preset Picture Setting with IEC 62087 provisional HDR10 dynamic test clip

461
462

If it is possible to manually adjust the backlight setting of the unit under test, repeat these tests in thedimmest manual backlight setting.

463
464
465
466
467

Note: EPA proposes that all testing performed for purposes of ENERGY STAR certification be performed
with ABC turned off. EPA does however recognize the potential saving opportunities that a wellprogramed ABC feature can deliver to consumers. As a result, when a test method is introduced to allow
for a better understanding of the relationship between ABC’s persistence and energy consumption,
reintroducing requirements for ABC-implementation can be evaluated.

468
469
470

Future ENERGY STAR TV Specification revisions will require an understanding of TV/HTD dimming lines
when power is plotted against dynamic luminance for multiple backlight levels. As such, EPA requests
test results in the dimmest manual setting for each of the three PPSs tested.

471
472

If the SDR Default PPS is also the SDR Brightest Selectable PPS, then there is no need to test this PPS
twice.

For this test, measurement, test preparation and configuration requirements are determined by theFederal Test Method prescribed in Table 3, except where the following test procedure indicatesotherwise.
i. Configure the TV in its SDR Default Preset Picture Setting with MDD and ABC off.
ii. Display the rtings.com contrast ratio test pattern19.
iii. If it is possible to manually adjust the backlight setting of the unit under test, set the display
backlight level so that the screen-center luminance is approximately 100+/-5 cd/m2 as
measured in center 1% of screen with camera photometer.
iv. Measure the luminance in the center of the black box immediately above screen center using
camera photometer with a 1% measurement window located in the middle of theaforementioned black box.
v. Calculate contrast ratio as Luminance_white/Luminance_black

486
487
488

Note: Calculating the contrast ratio per Section 4.5 will determine whether a model receives the HCRbased adjustment factor and provide metrics from which to establish a relationship between contrast ratio
and energy consumption for future specification revisions.

Note: EPA has observed that some TVs use significantly more power (e.g. > 10 watts) in standby-active,
low when Multicast DNS requests are present on the network. These are packets broadcast by anapplication (e.g. Spotify, YouTube) on one device (e.g. iPhone) requesting identification (i.e. local IP
addresses, device profiles) from other devices on the subnet. The traffic may be unrelated to the TV, but
the TV responds to notify the network that it is ready to receive casted content and then stays ready at ahigher power level for a period of time. Research is needed to further characterize this TV behavior and todevelop a network traffic test environment that is representative and repeatable using a packet generator(i.e. Ostinato). After that is developed, EPA will include the metrics currently labeled as TBD above.

EPA is open to inclusion of text similar to that in CTA-2043-B, STB test method: “Review the captured
power samples. If, during the 60 minutes of samples, it appears that a maintenance activity occurred (e.g.
the power consumption spikes up for a short duration), re-run the test. Using a charting utility (such as theutility in Microsoft Excel) can help to analyze the results.” EPA notes, however, that the direction to
update software before testing and the development of a network test environment is intended to limit thepossibility of a maintenance event and spikes related to LAN traffic during testing, respectively.
Stakeholders are invited to comment on the proposed tests.

Additional Standby Mode Tests

Without Smart Speakeri.

Standby-active, low shall be measured with the TV in its default configuration without aconnection to a smart speaker or other device besides the LAN equipment used for testing.
ii. At the end of the standby test period, wake time should be measured by pressing the power
button on the remote control and measuring the time period before an active HDMI SDR
video feed (e.g. looped IEC test clip) appears on the display.
iii. The SDR video clip shall be playing before TV power-down through wake. For TVs with a
Quick Start (QS) feature that is disabled by default: if the wake time is equal to or greaterthan 10 seconds, perform this standby-active, low test with QS enabled to enable compliancedetermination.

520
521
522

Note: The wake time condition included to determine whether a TV/HTD would be tested with Quick Start
enabled is consistent with the industry-standard CTA/ANSI-2037-B ten-second QS persistence rule
(Section 6.3.10.6.3).

Where the TV supports the capability, Standby-Active, Low Power and wake time shall be measured with
the TV in its default configuration and a smart speaker manufactured by Amazon connected andconfigured to wake the TV.
i. This test should be repeated for a smart speaker manufactured by Google after disabling the
Amazon speaker connection to the TV.
ii. For each of these tests measure voice-wake time to an active HDMI SDR video feed, whichshall be playing before TV power-down through wake.
iii. For TVs with a Quick Start (QS) feature, disable this feature before testing with a Smart
Speaker.

533
534
535
536

Note: EPA proposes to conduct testing with a smart speaker connected after all other additional tests toavoid requiring the performance of a factory reset on the TV/HTD to restore factory default settings.
Configuring a smart speaker to wake a TV/HTD may involve logging into a personal account held with the
speaker manufacturer on both products (a Google account for example).

Testing with multiple types of smart speaker is required, as previous testing has shown variation inenergy consumption with different brand, a relationship which EPA seeks to understand more about.
Amazon and Google smart speakers have been identified for these tests because their digital assistantproducts represent the largest market shares (both current and forecasted) by a wide margin.

541

544

The above chart, sourced from Statista, is one of many that shows that if a TV is paired with a digitalassistant today, it is likely to be from Amazon or Google. The brand with the next largest current sharehas far less penetration and is not currently configured to control non-Apple devices.

7.1.2

Implementation of Filmmaker Mode and Performance: EPA is interested to see if the increased
implementation of a “Filmmaker Mode” Preset Picture Setting by manufacturers is followed by atendency to apply the setting by consumers and how the characteristics unique to this setting
affect energy efficiency.

577
578

7.1.3

Color Quality and Energy Efficiency: EPA looks to explore the relationship between image quality,with respect to color (viewing angle, gamut size, etc.), and energy efficiency.

579
580
581

Note: Items in this section have been removed as many have been addressed in this Version 9.0
Specification. EPA has added the items above as they represent emerging technological advances thatshould be studied in future revisions.

Partners are encouraged to design products in accordance with the user interface standard IEEE
1621: Standard for User Interface Elements in Power Control of Electronic Devices Employed in
Office/Consumer Environments. For details, see http://eetd.LBL.gov/Controls.

Effective Date: The Version 9.0 ENERGY STAR Televisions specification shall take effect on
TBD. To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR
specification in effect on its date of manufacture. The date of manufacture is specific to each unit
and is the date on which a unit is considered to be completely assembled.

Future Specification Revisions: EPA reserves the right to change this specification should
technological and/or market changes affect its usefulness to consumers, industry, or theenvironment. In keeping with current policy, revisions to the specification are arrived at throughstakeholder discussions. In the event of a specification revision, please note that the ENERGYSTAR certification is not automatically granted for the life of a product model.
