2) Full Network Connectivity: The ability of the TV/HTD to maintain network presence while inStandby-Active, Low mode. Presence of the TV/HTD, its network services, and its applications, ismaintained even if some components of the TV/HTD are powered down. The TV/HTD can electto change power states based on receipt of network data from remote network devices, butshould otherwise stay in Standby-Active, Low mode absent a demand for services from a remote
network device. Full network connectivity is not limited to a specific set of protocols. Also referred
to as “network proxy” functionality and described in the Ecma-393 standard.
D) Special Functions10: Functions that are related to, but not required for, the basic operation of thedevice.
Note: Special functions include, but are not limited to, special sound processing, power saving
functions (e.g., Automatic Brightness Control).

78
79

1) Automatic Brightness Control (ABC): A feature that senses ambient light conditions and changes
display brightness accordingly, possibly reducing power consumption.

80812) Motion-based Dynamic Dimming (MDD): A feature that adjusts luminance in response to theamount of motion in the displayed image.

82
83
84

3) High Contrast Ratio (HCR) Display: A display where pixels emit no light when displaying a pure
black color, thus yielding a contrast ratio of infinity:1 when comparing these pixels against thosethat do emit light.

85
86

Note: EPA has consolidated the definitions of Special Functions to contain only those terms used in thisdocument.

87
88
89

EPA also proposes the definition of an HCR Display. For the purposes of this specification, the definitionencompasses the current (e.g., micro-LED and OLED) and anticipated display technologies that areunderstood to provide an exceptionally high contrast ratio.

90E) TV/HTD Settings and Menus:

91
92
93

1) Preset Picture Setting11(PPS): A preprogrammed factory setting obtained from the TV/HTD menu
with pre-determined picture parameters such as brightness, contrast, color, sharpness, etc.

95
96
97
98

2) Default SDR Preset Picture Setting: The as-shipped Standard Dynamic Range (SDR) Preset
Picture Setting that the TV/HTD enters immediately after making a selection from the Forced
Menu. If the TV/HTD does not have a Forced Menu, this is the as-shipped SDR Preset Picture
Setting. As referenced in this specification, default settings must be determined through direct
observation of the as-shipped configuration.

991003) Brightest SDR Preset Picture Setting: The user-selectable SDR Preset Picture Setting within the
Home Configuration in which the TV/HTD produces the highest screen luminance.

101
102
103

247

ii.

For PPSs with ABC enabled by default: Measurements at different illuminance conditions arethus taken (at 3, 12, 35, and 100 lux) per the forthcoming CTA-2037C: Determination of
Television Set Power Consumption and Average Luminance:

248
249
250

a) To calculate DL for the PPS: The value of DL used to represent the PPS for the
purpose of calculating POA_Average_Limit per Equation 5 shall be the calculated average of
the DL measurements taken at each illuminance condition, as outlined by Equation 1.

251
252
253
254

b) To calculate POA for the PPS: The value of POA that represents the PPS for the
purpose of calculating POA_Average per Equation 4 shall be the calculated average of the
POA measurements for the PPS taken at each illuminance condition, as outlined by
Equation 2.

255
256
257
258
259
260
261
262

iii. If the value for the DL used to represent an SDR PPS is measured or calculated to be lessthan 20 cd/m2, then 20 cd/m2 shall be the DL value used to represent the PPS for the
purpose of determining certification, and the value of POA used to represent the PPS shall be
the interpolated POA value of the PPS when the TV/HTD is set to a DL of 20 cd/m2. Likewise,
if the value of the DL for an HDR PPS is less than 10 cd/m2, then 10 cd/m2 shall be used as
the DL representing the PPS for the purpose of determining certification, and the value of POA
used to represent the PPS shall be the interpolated POA value of the PPS when the TV/HTD
is set to a DL of 10 cd/m2.

263
264
265
266
267

a) For PPSs without ABC enabled by default: The POA values of a PPS correlating to a
projected DL of 20 cd/m2 or 10 cd/m2 shall be calculated through interpolation of thelinear trendline created by plotting the PPS’s measured POA values at its default andminimum backlight setting (or brightness if no backlight-specific control is available)
against the measured DL values at the same points.

268
269
270
271
272

b) For PPSs with ABC enabled by default: The POA values of a PPS correlating to a
projected DL of 20 cd/m2 or 10 cd/m2 shall be calculated through interpolation of the
2nd order polynomial trendline created by plotting the PPS’s measured POA values at 3
lux, 12 lux, 35 lux, 100 lux, and the ABC-disabled datapoints against the measured DL
values at the same points.

EPA has used an updated dataset consisting of 41 2020-2021 TV models from 10 different manufacturers
to evaluate the criteria levels presented in Draft 1. This variety of TVs includes models with several
different resolutions, sizes, and display technologies. Furthermore, the dataset was obtained by testingthese TVs per the current iteration of the forthcoming CTA-2037C: Determination of Television Set Power
Consumption and Average Luminance test procedure, which includes provisions for testing TVs with ABC
enabled by default. Use of this dataset has led to the Agency proposing the following for determining P OA
and DL, as outlined in Section 3.3.1:

302
303
304
305
306
307
308

(1) For PPSs where ABC is enabled by default, EPA proposes using metrics that are the average DL and
POA taken at several illuminance conditions to represent the PPS in calculating POA_Average_Limit and
POA_Average metrics, respectively. As mentioned in the Draft 1 cover memo, EPA continues to monitor thedevelopment of an updated approach towards ABC testing. At this time, the approach as presented in theforthcoming CTA-2037C: Determination of Television Set Power Consumption and Average Luminancehas been developed to the extent that the Agency feels it appropriate to include ABC-based metrics in the
Version 9.0 criteria levels as proposed in this Draft 2 specification.

Recent testing has shown that many manufacturers configure their TVs to have ABC functionality enabled
by default in the Default SDR PPS, among others. A 2019 NEEA study of consumer behavior regarding
changing TV settings indicates that a majority of consumers do not change the default settings of the TV(although they may change PPSs), EPA believes that incorporating ABC-enabled metrics for PPSs thathave it enabled by default, as outlined in Section 3.3.1.ii, leads to criteria that are more representative of
how the TV is likely to perform in the home. Also, testing has illustrated the extent to which an ABC
feature can provide energy savings to the consumer and the Agency wishes to encourage persistence ofthe feature.

(2) If the DL used to represent a PPS is below a certain luminance, 20 cd/m2 for SDR PPSs and 10 cd/m2
for HDR PPSs, use interpolated values for POA at these specific DL values to represent the PPS in
calculating POA_Average. The goal of including these lower luminance thresholds (as presented in Section
3.3.1.iii) to determine certification is to ensure that there is no incentive to overly dim TVs in order to meet
ENERGY STAR criteria levels.

These thresholds were developed by looking at the measured DL data of 18 4K LCD TVs with ABC
functionality from four different manufacturers. Because there is no current policy incentive to set a TV’s
ABC algorithm in any particular way, EPA considers these datapoints to be representative of the backlightlevels that manufacturers believe consumers find desirable. As such, the proposed DL thresholds for
SDR and HDR PPSs are slightly below the DL that would be calculated per 3.3.1.ii for all but the dimmest
tested TVs. The proposed thresholds are not minimum luminance requirements and for any
current or future TV model with a representative DL below the threshold, there is no penalty, only
a lack of incentive to dim further to meet criteria levels. In other words, manufacturers may still
set their TV default settings to have a representative DL below this threshold, but compliance for
ENERGY STAR will be determined no lower than these thresholds. EPA believes that this proposal
will give manufacturers the freedom to program their backlight settings for however they believe will
deliver the best viewing experience while ensuring that ENERGY STAR is not providing an incentive to dootherwise. A chart showing the distribution of default DL values used to create these thresholds is below:

For PPSs with a representative DL value below its corresponding threshold, the datapoints gathered
through testing will be used to determine POA as outlined in Section 3.3.1.iii. When ABC is not enabled bydefault, the relationship between DL and power is observed through a linear trendline that passes throughthe datapoints of the PPS’s default DL and the manually-adjusted-dimmest backlight setting. However,the current dataset illustrates that this linear relationship between DL and power is not always present for
PPSs where ABC is enabled by default. As such, when a PPS has a representative DL below its
corresponding threshold, the trendline used to interpolate POA values shall be a 2nd order polynomial thatpasses through the DL datapoints taken at the four illuminance conditions and the DL when ABC isdisabled. A higher order equation such as this has been observed to accurately interpolate POA for all TVs
with ABC enabled by default in the current dataset.

Should a TV not be capable of displaying HDR10 content in an HDR format, it will not be

Note: EPA has replaced the On Mode Power requirements prescribed for each PPS as proposed in Draft
1 with an average On Mode Power requirement (Equation 4). The Agency believes that combining thisrequirement with the Average On Mode Power Limit (Equation 5) approach allows manufacturers more
flexibility in designing their TVs for efficiency – a model that would not meet power requirements for all
three PPSs may still be certifiable if the efficiency of the model’s PPSs meets requirements on average.

411
412
413

The On Mode Power Limits, as outlined in Table 1, have been updated to apply even stringency acrossvariations in product type (e.g., resolutions, display technology, size bins, etc.), as evident throughanalysis of the current, 2020-2021 model dataset.

414
415
416
417
418

420

The Average On Mode Power Adjustment Factors, as outlined in Table 2, have been updated in two
ways: (1) the three, resolution-based AFs presented in Draft 1 have been replaced by the single
AFResolution in order to eliminate the need to determine which AF applies to the TV/HTD and better apply aneven stringency across both common and atypical resolution categories and (2) the HCR AF that was
exclusive to 4K resolution models in Draft 1 has been replaced with AF HCR, which relates pixel count toefficiency in order to account for future models that may combine HCR-capable display technology withother resolutions.

422

EPA proposes to remove the requirement to verify contrast ratio through testing to determine AFHCR
applicability. This is due to the lack of a standardized testing approach for measuring contrast ratio andthe innate difficulty in arranging a test environment so that the light projected by a pixel does not influence
the measured luminance of an adjacent pixel. Because there is common understanding that some current
and anticipated TV technologies can precisely turn on/off individual pixels to provide an exceptionally highcontrast ratio, the Agency believes that Certification Bodies will be able to determine applicability of AFHCR
when reviewing the manufacturer-provided specification manuals during certification testing.

428

Analyzing the current dataset, approximately 39% of TVs meet these On Mode Power requirements. This
percentage does not incorporate the effect of Standby requirements on pass rates.

The following Standby Mode Requirements are based on measurements from the Federal Test
Procedure Standby-Passive Mode Test as well as the series of additional Standby-Active, Low Modetests outlined in the forthcoming CTA-2037C: Determination of Television Set Power Consumption and
Average Luminance, that are designed to measure standby power in a more typical network environment(e.g., multicast traffic on the network).

436
437

3.4.1

Standby-Passive Mode Power (PSTANDBY-PASSIVE), as measured per Section 7.3.2 Standby-Passive
Mode of the Federal Test Procedure, shall be less than or equal to 0.5 W.

438
439

3.4.2

For TVs capable of network connectivity, Standby-Active, Low Mode Power (PADDITIONAL-STANDBYACTIVE-LOW), as measured per CTA-2037C, shall be less than or equal to 1.0 W.

Note: EPA proposes to reduce the number of Additional Standby-Active, Low Mode Power tests requiredin Draft 1 by only requiring the information gathered through testing Standby-Active, Low Mode after
powering down from the Default SDR PPS for certification evaluation. Additional research has shown that
there is no significant correlation between the PPS selected for On Mode and energy usage while inStandby Mode.

446
447
448
449

452

The Agency proposes to remove the requirement for Standby-Active, Low Mode Power as measured per
the Federal Test Procedure because the requirement set for this mode as measured per CTA-2037C is ofequal stringency (1 W). This proposed removal follows EPA’s understanding that the standby-activemode power as measured per CTA-2037C will always be higher than that measured per the Federal Test
Procedure because it requires the configuration of wake-by-voice and wake-by-cast capabilities if
available, which the Federal Test Procedure does not. As a result, a requirement based on
measurements taken per the Federal Test Procedure would be redundant because the TV must alreadymeet an identical requirement for a higher power consuming version of the same mode.

453
454
455
456
457

EPA also proposes to lower the Standby-Active, Low Mode requirements from 2 W to 1 W. The current,
2020-2021 model dataset shows that several manufacturers have been able to configure their smart TV
lineups to have Standby-Active, Low Mode Power values of well below 1 W, despite the industry average
being much higher. The overall pass rate of TVs meeting both On Mode and Standby requirements, ascalculated for the current dataset, is 20%.

The Agency proposes to delete power requirements and associated testing for Download Acquisition
Mode (DAM). Looking at the products certified to ENERGY STAR since 2016, the Agency has seen adecline in the hospitality-specific models that employ a DAM function and as such, believes that theavailability of these models in general has declined in recent years (as smart TVs have grown in market
share). EPA would appreciate stakeholder feedback and associated data regarding whether DAM
requirements are still relevant.

Note: Since publishing the Draft 1, EPA has begun to work with stakeholders in the Consumer
Technology Association (CTA) R4 Working Group 13 to develop the CTA-2037C: Determination of
Television Set Power Consumption and Average Luminance test procedure that is based on the same
approach to measuring TV power and projected luminance as the additional test procedures outlined in
Draft 1. As such, and so long as the working group continues to make timely progress towards the
finalization of CTA-2037C, the Agency intends to reference it for use in testing to determine compliancewith this specification. This will allow for ENERGY STAR to align with the industry accepted approach tomeasuring TV efficiency and reduce the test burden that having an additional test method would put on
manufacturers looking to certify products under the program.
