Beware Using HOME mode on Sony televisions ( at least those made after 2010 year ) will have what is called peak luminance ratio , meaning that home mode will limit the POWE consumption ( TURN ON AN ENERGY SAVINGS ) and cut off the power from 100 % ( shop mode ) to 70 % . If you want proper and full performance of your tv you should do Auto Set up Wizzard/Factory reset and then choose SHOP MODE and on the next steps make sure u DISABLE THE DEMO and E-pop futures ( cos they will display demos and reset ur settings ) . Using Home mode will not just limit the maximum amount of backlight it makes the whole image way off than what is supposed to be . Even if u Set up Home mode backlight to 10/10 maximum , switching to shop mode would give u better image even if u have backlight set to way lower option 4/10 and so . Basicly Home mode is like turning on the POWER savings option .
I am an owner of European KDL-55HX750 and i can confirm that there is a huge difference between Shop and Home mode . As i said its not just different settings for the Picture presets and so , Same picture settings give different results . I have set the tv as a computer monitor via HDMI , have FULL PIXEL 1:1 mapping , Full Color space/range 0-255 , and Scene selection set to Graphics ( all of you who want best performance and 1:1 mapping should make sure these option are set , for example all other scene selections make like " smears " around the text even with full pixel mapping " ) . Can anyone with US model confirm it ? Firmware should be the same for both versions only difference is that US model has MotionFlow on 240/480Hz instead of 200/400 for the EU model .
Turns out there is a Europe Union directive 642/2009 which regulates energy efficiency . Which basicly says all Tvs that have no DVI ( because tv with dvi , like samsung for example have HDMI1 set as DVI ( no audio ) is intended to work as a PC monitor ) do not fall in that category . Since ALL HDMI inputs on the Sony have audio output they r not DVI so this tv falls in the tv category and according to the Europe Union 642/2009http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/tv_vcr/Forced_Menu_Proposal_111607.pdfhttp://ec.europa.eu/energy/efficiency/ecodesign/doc/regulations/guidelines_ecodesign_televisions_may_2011.pdf
"With this in mind, stakeholders suggested that use of a forced menu option may meet manufacturers’ need for a retail setting while meeting EPA’s need for products to be used by consumers in a lower power setting.
Thus, EPA calls for the use of IEC 62087 and clarifies that products with a forced menu at start up (i.e., a menu where a user must select a mode in which the product will operate prior to being able to view anything on the TV) may test and qualify their products in a standard mode. To further consistent messaging to consumers about how to set their TVs for home use, EPA is calling on manufacturers to provide two choices: “home” or “retail” in the interface that appears when a consumer or retail customer first starts a TV that makes use of a forced menu option."
"Question: Are products with SDI and/or DVI and additional standardised video signal paths
included in the scope of the regulation considered to be a "television monitor"?
Answer: No, products which provide SDI and/or DVI connectors are not considered to be
"television monitors" and therefore not in the scope of the regulation, irrespective of any other
signal connectors which are also fitted to the product."
"Answer: Article 2, definitions, point 10 states that ‘forced menu’ means a set of television
settings pre-defined by the manufacturer, of which the user of the television must select a
particular setting upon initial start-up of the television.
If a television offers a choice of non-picture related settings, e.g. language or country, on
initial activation, then such settings are not regarded as ‘forced menu’, as these settings have
no influence on the energy consumption of the TV.
If the television does not provide a forced menu (for example containing “home” and “shop”
modes), then the picture settings of the television as delivered by the manufacturer shall be
used for power consumption measurements."
4. Brightest on-mode condition
Question: What is meant by "brightest on-mode condition provided by the television"?
Answer: The "brightest on-mode condition" is the product’s maximum luminance that can be
provided by the television when "manually" adjusting the relevant picture settings while
maintaining optimum picture contrast as tested using relevant grey-scale test patterns.
In case that a preset mode (for example, “shop” mode) is identified as the brightest on-mode
condition provided by the television, manufacturers shall ensure that no further upward
modification of the luminance through manual adjustment is possible by the user.
Further to the third indent of point 5(b) of Annex I, the sequence of steps for achieving a
stable condition providing the brightest on-mode condition applied for conformity assessment
has to be included in the technical documentation.
5. Peak luminance ratio
Question: What are examples of appropriate test patterns for establishing the peak luminance
Answer: Annex II, 3(a) requires that “Measurements shall be made using a reliable, accurate
and reproducible measurement procedure”, where Annex II, 3(b) demands "a full (100 %)
white image, which is part of a ‘full screen test’ test pattern that does not exceed the average
picture level (APL) point where any power limiting occurs in the display luminance drive
In order to deliver reliable, accurate, and reproducible measurements of peak luminance ratio,
manufacturers have to choose an appropriate test pattern that meets the applicable
requirements. The test pattern chosen should not introduce power limiting and should not
introduce any other display power drive irregularity that distorts a linear power to luminance
characteristic at the home mode.
ANYWAY BASICLY THE POINT OF USING THE HOME MODE IS ONLY IF YOU WANT TO SAVE ENERGY , BECAUSE IT DRASTICLY CUTS OFF THE REAL PERFORMANCE OF YOUR TV .
All samsungs work on 100 % because they escape this category of EU because as i said they have DVI ( samsung give u pixel mapping only on HDMI1/DVI and no audio on that HDMI because it is indeed a DVI connection ) . While SONY give u a global settings for FULL PIXEL 1:1 mapping which can give u FULL PIXEL on all 4 HDMI ports and also have HDMI Audio .
I Will provide couple of pics attachments soon so u can see the difference
Also i would like to ask the moderators to consider if this thread should be made sticky/imporant as it turns out that very little amount of people are aware of the information above in details .
