You can declaratively create pages that display master-detail data using the Data Controls panel. A change in the current row of the master view object instance causes the row set of the detail view object instance to refresh to include the details for the current master.Ģ4.2 Identifying Master-Detail Objects on the Data Controls Panel For example, in the Fusion Order Demo application, there is a view link from the ProductsVO view object to the WarehouseStockLevelsVO view object based on the ProductId attribute, both contained in the application module data model, as shown in Figure 24-1. ![]() To enable master-detail coordination, you must add both the master view object and the detail view object instances to the application module data model. When using ADF Business Components in combination with the ADF Model layer and ADF Faces UI components, the data model automatically updates to reflect any changes to the row sets of these business objects. To display master-detail data on a page using ADF data binding, you exclusively use data model view link instances, which support master-detail coordination. The view link associates a row of one view object instance (the master object) with one or more rows of another view object instance (the detail object). As described in Section 5.1, "Introduction to View Objects", a view link represents the relationship between two view objects, which is usually, but not necessarily, based on a foreign-key relationship between the underlying data tables. In ADF Business Components, a master-detail relationship refers to two view object instances that are related by a view link. DisplayHDR True Black allows for significantly deeper black levels in addition to greater dynamic range and improved rise time – enabling a visually stunning experience for home theater and gaming enthusiasts in subdued lighting environments.24.1 Introduction to Displaying Master-Detail Data In January 2019, VESA followed this up with the release of the DisplayHDR True Black standard, a variant on DisplayHDR, which is optimized for emissive display technologies – including organic light emitting diode (OLED) and future microLED displays. The first release of the DisplayHDR specification, DisplayHDR version 1.0, was introduced in December 2017 and is geared toward liquid crystal displays (LCDs). Delivering a robust set of test metrics for HDR that clearly articulates the performance level of the device being purchased.You can download DisplayHDR Test Tool for HDR display performance verification aimed at professional users here. Developing an automated testing tool that end users can download to perform their own testing if desired.Creating an open specification for the PC industry shared publicly and transparently.With DisplayHDR, VESA is helping to alleviate consumer confusion surrounding HDR performance specifications in the PC space by: The High-Performance Monitor and Display Compliance Test Specification (DisplayHDR) from VESA defines the display industry’s first fully open standard specifying HDR quality, including luminance, color gamut, bit depth, and rise time (see EE Times article). What’s the difference between HDR-10, HDR-1000, and DisplayHDR 1000? Read our post “ Not All HDR is Created Equal” to learn more. Until the website displays DisplayHDR 2000, any such logo usage should be assumed to be unapproved and deceptive. VESA does not endorse the use of this logo unless and until a DisplayHDR 2000 tier has been officially announced by VESA, and any products claiming to meet this tier level have been officially certified by VESA and are listed on our website at. However, VESA takes any misuse of our trademarks and logos seriously. VESA has no knowledge of the origins of the DisplayHDR 2000 logo currently posted on these display listings on the Taobao website. There is no “DisplayHDR 2000” tier in the VESA DisplayHDR specification and logo program at this time. VESA wishes to set the record straight on this development. In addition, several media outlets have reported that these monitors have received “DisplayHDR 2000” certification from the Video Electronics Standards Association (VESA). VESA Addresses Use of Illegitimate DisplayHDR 2000 Logo: Recently, the Chinese retail website Taobao has listed two display products that have a VESA certified “DisplayHDR 2000” logo – an updated Samsung Odyssey G9 monitor as well as a new Acer EI491CRG9 monitor. Consumers can refer to the current list of certified DisplayHDR products on this website to verify certification. If a monitor claims HDR support without a DisplayHDR performance specification, or refers to pseudo-specs like “HDR-400” instead of “DisplayHDR 400” it’s likely that the product does not meet the certification requirements. ![]() DisplayHDR is the open standard for HDR quality and performance and only displays that meet all the specifications may carry the DisplayHDR logo.
